Title: Manufacture of thin film
Inventor: SAKAI OSAMU
IPC: H05H1/46
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To form a thin film on a substrate with a large area in uniform film thickness by decomposing material gas made in a plasma state by means of electric energy into active species, depositing the active species on the substrate and making the supply time of electric energy to be shorter than plasma density relaxation time. SOLUTION: A glass substrate 7 is fitted onto the face of an electrode 3 toward an electrode 2 as a substrate where an a-Si film is grown. Material gas is supplied to a chamber 6 from a material gas holder 5 through a gas jetting port 4. The supply/restraint of higher frequency energy are repeated on a power generation device 1, and the halt time of electric energy becomes substantially equal to supply time. The material gas of SiH4 is set to a plasma state and SiH4 is decomposed into the active species. The active species are deposited on the glass substrate 7 and the a-Si film is formed. At that time, the supply time of electric energy is made to be shorter than plasma density relaxation time and to be shorter than temperature relaxation time, if desirable.

IPC: B41J2/045
Filed: 1985-08-13
Abstract: PURPOSE:To equalize air flow rates among each air discharge opening by forming projecting sections in intermediate sections among ink discharge openings in an ink nozzle member or an air nozzle member and in the direction orthogonal to the direction of arrangement of the air discharge openings or ink discharge openings and shaping respective projecting section so that clearance sections are left between the ink nozzle member and the air nozzle. CONSTITUTION:In an air path 7, projecting sections 16 are formed integrally in intermediate sections among ink discharge openings 9 in an ink nozzle member 5 and in the direction orthogonal to the direction of arrangement of the ink discharge openings 9 and each projecting section 16 does not reach an air nozzle member 3 and is shaped so that there is slight clearances between the air nozzle member 3 and the ink nozzle member 5. The clearances among respective projecting section 16 and the air nozzle member 3 are set in narrowness of approximately one third or two third as large as other sections where the air nozzle member 3 and the ink nozzle member 5 are faced oppositely. The air path 7 is divided approximately at every ink discharge opening 9 and every air discharge opening 10 in the direction of arrangement of the air discharge openings 10 by the projecting sections 16, thus equalizing the flow rates of air flowing into each air discharge opening 10 from an air chamber and flowing out of respective air discharge opening 10.

Title: Piezoelectric resonator
Inventor: NAKATANI HIROSHI
IPC: H03H9/17
Filed: 1982-10-08
Abstract: PURPOSE:To suppress the spurious response due to the thickness oscillation component of a piezoelectric substrate by adding a mass to the piezoelectric substrate and applying damping to the thickness oscillation component, in the piezoelectric resonator having the oscillation mode other than the thickness oscillation mode of the piezoelectric substrate. CONSTITUTION:Electrode films 2 and 3 made of a metal such as Ag are formed on the electrode forming major planes opposing with each other of the piezoelectric substrate 1 of square type having the spread oscillating mode, and a different kind of film 4 is formed over the entire surface by the sputtering on the electrode film 2. In taking the total weight of said electrode films 2, 3 and the different kind film 4 as 2-5% of the weight of the piezoelectric substrate 1, the ratio of peak and notch of the main response is almost constant from zero to some 5% of said weight ratio, while the ratio of peak and notch is small rapidly in the spurious response, when said weight ratio exceeds almost 2%. Thus, the weight ratio is taken to 2-5% where the suppression of the main response is small and the suppression of the spurious response is large.

Title: Magnetic resonance image picture method
Inventor: SUWADA TAKESHI
IPC: G01R33/48
Filed: 1989-07-12
Abstract: PURPOSE:To clearly image a tomographic image of a transfer part by suppressing the magnetic resonance signal generated from the static part of an inspected body and collecting the magnetic resonance signals generated from the transfer part, in emphasis. CONSTITUTION:Though the magnetic resonance signal B1 generated from a static part is suppressed by constituting each inclined magnetic field from a plurality of pulses, the magnitude of the magnetic resonance signal B2 is proportional to the volume occupied on an inspected body 1. Therefore, when the blood stream in a human body is image-displayed, the magnetic resonance signal B1 is obtained in the larger signal form in comparison with the signal B2, since the volume of the static part is larger than that of a transfer part (vein part). However, when the flow encode magnetic field in bipolar form in which the polarity is reversed in the sequence in two times is applied, and the magnetic resonance signal B is reduction-calculated, the magnetic resonance signal B1 supplied from the static part is suppressed. Therefore, the generation of the phase disturbance in the transfer part of the inspected body 1 is prevented, and the transfer part can be clearly image-pictured.

Title: Lsi designing method
Inventor: KUMAGAI SATORU
IPC: H01L21/82
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To improve designing accuracy when designing clock interconnections for an LSI having multilayered interconnections by correctively designing the clock interconnections in consideration of the multiple layers. SOLUTION: The LSI designing method comprises: a step S1 of inputting data such as layout information and terminal connection information about elements of an LSI having multilayered interconnections; a step S2 of inserting buffers into timing- affecting interconnections; a step S3 of roughly forming multilayered interconnections for signal lines other than the timing-affecting interconnections; a step S4 of roughly forming the timing-affecting interconnections; a step S5 of selecting multilayered interconnections crossing the timing-affecting interconnections; a step S6 of estimating the volume of the multilayered interconnections selected by the step S5 crossing the timing-affecting interconnections; a step S7 of forming isodelay interconnections for the timing-affecting interconnections;  a step S8 of completely interconnecting the signal lines other than the timing-affecting interconnections; and a step S9 of outputting interconnection information. The volume of the multilayered interconnections crossing the timingaffecting interconnections is corrected more with less number of layers through which the timing-affecting interconnections cross the multilayered interconnections.

Title: Linear motor type power door device
Inventor: MATSUKAWA KOJI
IPC: E05F15/60
Filed: 1994-07-29
Abstract: PURPOSE:To simplify a structure by feeding a current flow through the primary winding of a long-sized primary conductor disposed to a long cylindrical door support frame and moving a long-sized moving body for holding a door oppositely faced to the primary conductor along the primary conductor by generated magnetic flux. CONSTITUTION:When the signal of a human-body detecting sensor is received, a control section makes three-phase current flow through a primary winding 5 from an inverter circuit, and a shifting magnetic field is generated around the primary conductor 3. Overcurrent is generated in the secondary conductor 12 of a moving body 11 by the magnetic flux of the shifting magnetic field while thrust is generated in the moving body 11 and a door 22 is moved in the direction of opening or closing. When the direction of thrust is changed, a signal altering the direction of three-phase current made to flow through the winding 5 is output from the control section. When the door 22 is brought near to both ends of a support frame 1, a position sensor detects the approach, the control section adjusts current frequency, and the door 22 is stopped smoothly. An on-off switch is operated, and the door 22 is opened and closed at a desired place. Accordingly, a magnetic detecting sensor for sensing the place of the door is unnecessitated, thus simplifying structure.

Title: Method and instrument for measuring interval between parallel flat plates
Inventor: TAKEBAYASHI MOTONARI
IPC: G01B5/14
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the interval between parallel flat plates can be measured easily through such a simple operation as rotation. SOLUTION: In the method for measuring the interval between parallel flat plates, the interval between parallel flat plates is measured in such a way that a bar-like pipe having a prescribed length is rotated around a fixed center of rotation so that the radius of gyration of the front end of the piece may become constant (L) and the angles of rotation (θ1 and θ2) of the front end of the piece until the front end comes into contact with the lower surface of the upper flat plate and the uppers surface of the lower flat plate (e.g. the upper electrode 4 and the lower electrode 5) from a horizontal state are detected. Then the interval between the flat plates is measured based on the detected angles of rotation.

Title: Television receiver with opening and closing door
Inventor: ICHIMURA HIDEKAZU
IPC: H04N5/64
Filed: 1981-11-07
Abstract: PURPOSE:To specify the stop position of an opening and closing door (door) by turning a motor for a prescribed time in a driving direction after detecting the position where the door is fully opened or closed. CONSTITUTION:When a door is fully opened, a switch for detecting the position of the opened door is turned on to hold terminals 9L' and 9R' at high potentials. Consequently, NOR circuits 27L and 27R generate high-potential outputs to hold monostable multivibrators 28L and 28R at low potentials, and monostable multivibrators 29L and 29R are reset after a prescribed time. Therefore, the switch is turned on to stop motors 6L and 6R a prescribed time later. When the door is fully closed, a switch for detecting the position of the closed door is turned on to hold terminals 8L' and 8R' at low potentials. Consequently, waveform shaping circuits 25L and 25R generate high-potential outputs to invert the monostable multivibrators 28L and 28R, and the monostable multivibrators 29L and 29R are reset after a prescribed inversion time and stop the motors 6L and 6R. Thus, the motors are stopped after idling to specify the stop position of the door.

Title: Key telephone set
Inventor: SEKIGUCHI SHINICHI
IPC: H04Q3/58
Filed: 1981-11-06
Abstract: PURPOSE:To release ineffective holding securely by providing a means of outputting a forcible on-hook signal when a holding state is set continuously for a specified time after the time when a holding alarm tone is generated. CONSTITUTION:On receiving a holding signal, a control part 3 drives a holding relay Ry2 to switch contacts SW2-1 and SW2-2 to the side of a holding tone oscillator 4 and the side of a holding alarm oscillator 5, and a holding tone is sent to trunk lines L1 and L2 to connect the oscillator 5 to a speed line O1. The control part 3 sends a clocking start indication to a timer 6 for a holding alarm. When a holding state is reset by a terminal set before a time-up state is detected, timers 6 and 7 are reset through the control part. When, however, the timer 7 detects the time-up state to send a signal to the control part 3, the control part 3 finishes energizing a call relay Ry1 and the relay Ry2 and resets them, and consequently the trunk lines L1 and L2 are disconnected forcibly from the telephone set 1 to set an on-hook state. Consequently, a free state is prevented securely to improve the effect of trunk lines.

Title: Output voltage control method of pwm inverter
Inventor: HANADA MASASHI
IPC: H02M7/48
Filed: 1990-07-06
Abstract: PURPOSE:To eliminate a change in voltage caused by changing a carrier pulse number from low speed to high speed by correcting the output voltage control signal of an inverter through a corrected value at the time of changing the pulse number and by correcting the change of the fundamental wave component of a PWM wave, which is caused by changing the pulse number, according to the corrected value. CONSTITUTION:In order that the output frequency is controlled from low frequency to high frequency, a carrier pulse number is changed according to a frequency domain and, at the same time, an output voltage control signal is corrected by a corrected value so that the change of an output voltage accompanying the change of the carrier pulse number is corrected. Therefore, the stepwise change of the output voltage at the time of changing the pulse number is eliminated so that it is possible to eliminate not only the uneven rotation of a motor 3 and the generation of an overcurrent in a power inverter part 2 but also the change in the ratio of frequency to voltage in each operating stage.

Filed: 1984-08-28
Abstract: PURPOSE:To provide a construction of generating a sampling pulse simply and at a low cost, by using an oscillation output of a fixed-frequency oscillator as sampling pulse. CONSTITUTION:An input signal is sampled and converted into an digital signal with an A/D converter 2 according to a sampling pulse applied to a fixed-frequency oscillator 9 and (n) cycles [(n) is integer of 2 or more] of reference input signals are fetched into a memory 7. A CPU3 performs a Fourier analysis on (n) data for the cycles of the reference input signal feched as one cycle data to determine amplitude data for respective degrees of harmonic. Then, the degree of harmonic giving the peak in the amplitude data is found corresponding to the fundamental wave and high harmonic of the input signal referring the amplitude data for degrees of harmonic. Based on the amplitude data for the degrees of harmonic before and after the degree of harmonic thus obtained, errors due to non synchronization between the sampling pulse and the input signal is corrected to determine the amplitudes of the fundamental wave and harmonic in the input signal, which is outputted to a printer 8.
