Title: Heat-sensitive recorder
Inventor: SAITOU TAMIO
IPC: H04N1/23
Filed: 1980-01-31
Abstract: PURPOSE:To shorten a transfer time of a recording signal and to enable a high- speed recording, by a method wherein, in a simultaneous drivind type heat-sensitive recorder, shift registors for reading a recording signal are divided into a plural number of groups and a recording signal input terminal is mounted at each group. CONSTITUTION:Shift registors 2, consisting of the number of bits being equivalent to that of heating resistors 5, are divided into (n) pieces of groups 2a-2n consisting of a plural number of the consecutive bits, and recording signal input terminals 1a-1n are mounted at each group. In order to enable the shift registors 2 to read the recording signal equivalent to a line, the recording signals divided beforehand are simultaneously inputted from the terminals 1a-1n, and are transferred in turn to the right in the group by means of a clock signal. This shortens the transfer peiod of the recording signal to 1/n in comparision with the shift registor in which all bits are connected in series.

Title: Magnetism detecting element
Inventor: SHIBAGAKI SHIGEKI
IPC: G01R33/035
Filed: 1988-01-19
Abstract: PURPOSE:To improve the sensitivity of a magnetism detecting element and to prevent fluctuation due to temperature, by providing a superconductor and a piezoelectric body which detects the Lorentz force generated due to the Meissner effect as stress at one surface of the pressure receiving surfaces. CONSTITUTION:Electrodes 2 and 2 are deposited on two surfaces of a piezoelectric body 1 having a crystal structure by evaporation and the like. The two surfaces are arranged at aright angle to the crystal orientation where the piezoelectric effect of the piezoelectric body 1 appears most intensely. A superconductor 3 is deposited on one of the electrode 2 by the same way. The other electrode 2 is fixed to a fixing plate 4. When this element is placed in a magnetic field 8, a screening current which repels the magnetic field 8 flows in the surface of the conductor 3. Lorentz force is generated in the conductor 8 due to the Meissner effect and transmitted to the piezoelectric body 1. At this time, since one end of the piezoelectric body 1 is fixed 4, the transmitted Lorentz force becomes stress. The piezoelectric body 1 is contracted or expanded with the stress, and a potential is generated between the electrodes 2 and 2 which are disposed on both ends. The magnitude of the potential is detected with a voltmeter 7 through a lead wires 6. The intensity of the magnetism in the magnetic field 8 is measured as the voltage.

Title: Control of knocking in multi-cylinder engine
Inventor: ANZAI KATSUSHI
IPC: F02P5/153
Filed: 1983-01-26
Abstract: PURPOSE:To prevent the generation of output reduction by a method wherein the amount of spark delay angle of a specified cylinder, remote from a knocking sensor mostly, is made larger than other cylinders in only an operating area, in which the knocking upon high revolution and high load can not be detected easily. CONSTITUTION:An electronic control circuit 34 decides at a predetermined crank angle by the ratio of the amount of air Q, detected by an airflow meter 2, and a revolution signal N, detected by a sensor 32, whether an engine condition is in a knocking control area or not, and if it is in the control area and the generation of the knocking is detected by the signal of the knock sensor 18, the knocking is controlled by subtracting the correcting amount of the spark delay angle from the basic amount of spark delay angle. Here, the detection of knocking of the specified cylinder becomes difficult in accordance with the change of an operating condition which is entering into the high revolution and high load area, therefore, the amount of spark delay angle of the specified cylinder, remote from the knocking sensor 18 mostly, is made larger than the other cylinders in only the high revolution and high load operating area. Thus, the reduction of the output of the engine and the deterioration of fuel consumption may be prevented even when the knocking control is applied to all of the cylinders simultaneously.

Abstract: PURPOSE:To shorten a data processing time and to prevent the error in calculation by processing arithmetically the difference between the measuring value of the patterns provided at a specified spacing on an object to be measured from a reference position and the set value of the spacing of the set patterns. CONSTITUTION:The set spacing P between slits S formed on an object 3 to be measured is inputted as a set value D=P by a setting part 14 to a multiplication circuit 13. When the left end of the first slit S coincides with the base line (reference position A) of a scope 6, a latching circuit 10 and the circuit 13 are reset. The slit S is moved by one pitch and where the base line H coincides with the left end of the next slit S, the signal for the extent of the movement from a detector 4 is latched as a count value M of a counter 100 in the circuit 10. The product of the first control signal C=1 of the circuit 13 and D and the difference with the M from the circuit 10 are calculated and is outputted to a display 15. The differential value is measured in a short time by the repetition of the above-mentioned operation and the error in the calculation is prevented.

Title: Power supply control circuit
Inventor: KIN KEISEI
IPC: H02J1/00
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To conduct stable operation by generating a prescribed disenabling signal as the voltage of the level different from a level detection part is applied. SOLUTION: When a switch is turned on with power supply voltage Vcc kept at ground level, power supply voltage rises gradually and only the threshold voltage of an NMOS transistor NM3 increases, the voltage of a contact A begins to increase. The voltage of a contact B in a low condition is applied to the gate of a PMOS transistor PM4, a disenable signal DE in a high condition begins to output. When the threshold voltage reaches twice, an NMOST transistor NM4 rises. When it reaches three times, an NMOST transistor NM5 is turned on, and the voltage of a contact C rises. When it becomes larger than the threshold voltage of an NMOST transistor NM6, the potential of the contact B is at a low level. It is thus possible to conduct stable operation.

Title: Overload prevention method for swash plate type axial piston pump
Inventor: HOSHINO NOBUAKI
IPC: F04B1/20
Filed: 1990-01-20
Abstract: PURPOSE:To maintain discharge pressure at a set pressure even at the time of an over-load condition by constituting a swash plate to be automatically rotated in such a way that its tilt angle becomes small by the action of the moment based on the pressure within a cylinder bore faced to a discharge port when discharge pressure exceeds a set value. CONSTITUTION:When discharge pressure P exceeds a set value, the moment (Md-Mi) (Md and Mi represent moments making the tilt angle alpha of a swash plate 11 large and small respectively) overcomes the spring force of a spring 23 so that the swash plate 11 is rotated to the direction in such a way that its tilt angle alpha becomes small. This thereby causes the stroke of a piston 12 to be reduced so that an increase in the discharge pressure P is restrained. When the swash plate 11 is rotated to a position where the discharge pressure P is turned out to be the set value, the moment (Md-Mi) is balanced with the spring force of the spring 23 so that the swash plate 11 is held at the position of the tilt angle alpha at the time while the discharge pressure P is maintained at a set pressure. This thereby allows the discharge pressure P to be maintained at the set pressure, thereby surely preventing a pump from being over-loaded.

Filed: 1982-01-29
Abstract: PURPOSE:To obtain a circuit system which is suited to an AM receiver, etc. of a car without extreme deterioration of sound quality, by connecting smoothly as much as possible the front and back sides of a part where a signal is omitted due to a noise. CONSTITUTION:A signal waveform (e) containing impulsive noise is made to pass through a switch circuit including a circuit that has a fixed delay time (a fixed level required only at a desired frequency band) and holds a signal at a signal level obtained immediately before cut-off and during a noise detecting period. Thus a signal waveform (d) shown by a dotted line is obtained. The level at a point R is equal to the level at a point Q of the waveform (e) for the waveform (d) in which the cut-off time (t2-t2) is identical with a delay time (gamma). Then a current which is proportional to a level difference (Q-P) obtained immediately before the cut-off of the waveforms (e) and (d) is supplied to the above-mentioned holding circuit during a cut-off period. As a result, it is possible to turn the waveform (d) into a waveform of a solid line.
