Title: Aluminizing method and device
Inventor: AKAO MANABU
IPC: C23C2/12
Filed: 1993-09-09
Abstract: PURPOSE:To apply an aluminizing treatment uniformly over the entire part of an annular or cylindrical ferrous blank. CONSTITUTION:A blank W is immersed into an aluminum bath 3 in the state of hanging clown this blank from a hook member 2. This hook member 2 is inclined in a tangent (a) direction of an engaging point for the hook member of the blank W and is detained in this sate to a detaining part 6 at the front end of an inclined diaphragm 5. This diaphragm 5 is vibrated by a vibrator 13 mounted thereon to vibrate the hook member 2 in its axial line direction. Vibrations having components in a vertical direction and a tangent direction are applied to the blank W by inclination of the hook member 2. The blank W is rotated in the aluminum bath by the vibrating component in the tangent direction, by which the surface of the blank is uniformly aluminimized over the entire surface.

Title: Fault detecting system for transmission line
Inventor: TAKAHASHI YASUO
IPC: H04B3/46
Filed: 1982-12-21
Abstract: PURPOSE:To ensure a line operation by means of a spare line if the using transmission line has a fault by transmitting a test signal to a spare transmission line from high-order station and detecting previously a fault of the spare transmission line by a fault detecting means for spare transmission line while the using transmission line is working. CONSTITUTION:A PCM data end office 4 of a high-order station is connected to a PCM data end office 10 of a low-order station via a using transmission line 8. Then a multiplex signal is transmitted to the line 8 in a normal state under the control of a main control part 1 of the high-order station. When the multiplex signal is transmitted, a test signal is sent to a spare transmission line 9 via a transmission/reception control part 6 and an MODEM7 of the high-order station. Then the test signal is transmitted to a main control part 16 via the MODEM7 and a transmission/reception control part 14 of the low-order station. Then the part 16 transmits an answer signal to the control part 1 via the line 9 as long as the line 9 has no fault. Thus the fault of the line 9 is previously detected to cope with a fault generated to the line 8.

Title: Current-voltage conversion circuit
Inventor: SUZUKI FUMIO
IPC: H03F3/343
Filed: 1988-09-08
Abstract: PURPOSE:To perform current-voltage conversion with high accuracy by constituting a circuit so as to eliminate the current amplification factor of a transistor comprising a current mirror circuit and an Early's effect. CONSTITUTION:The transistors 1-3 are formed in current mirror constitution. Since voltages between the collectors and emitters of the transistors 1 and 2 are set at 2.VBE, collector currents on both transistors 1 and 2 are set identically due to the fact that the Early's effect functions similarly on both transistors 1 and 2. Consequently, the collector current of the transistor 2 goes to 1s, and that of the transistor 5 goes to Is-Ib. At this time, the current on a resistor R goes to Ib+(Is-Ib)=Is, therefore, the voltages at both ends of the resistor R goes to Is.R, which eliminates the influence of the Early's effect and the current amplification factor of the transistor.

Title: Output level adjusting system
Inventor: SOEJIMA TETSUO
IPC: H04L12/40
Filed: 1983-11-29
Abstract: PURPOSE:To increase sufficiently a network termination and a terminal device by adjusting an output level from each terminal device so as to be a prescribed amplitude at a network termination reception point. CONSTITUTION:''0'' is inserted to a monitor pattern inserting position MT of Fig. (B) at first in a terminal device desired to be adjusted and the result is transmitted to an outgoing line T. The network terminal 1 receives it and reflects it as an MR to an outgoing line R. Then an output level adjusting device 8 of the terminal device increases the level by a minute level DELTAV and transmits the result to the line T. The network termination reflects it similarly as above. The operation like this is repeated and the output level incremented numbr of times is checked until the MR on the line R at the terminal device reaches ''1'' at first. Suppose that this is K-time, then the said incremental number of times as the output level of the final ''1'' code becomes an amplitude equivalent to 2K-times. The ''1'' code output level is adjusted so as to be received as the amplitude double the threshold value of the receiver of the network terminal from the terminal device independently of the range from the network termination of the terminal device.

Title: Device containing means for mass spectrum measurement
Inventor: SUCHIIBUN WAADO DAUNII
IPC: G01N27/62
Filed: 1993-09-10
Abstract: PURPOSE: To detect and count particles floating in gas, to determine their size, and to analyze their chemical composition by detecting the number and mass of ionized fragments and the charge conveyed by the ionized fragments. CONSTITUTION: A mass spectrograph 12 is placed on the same line as the focal point of a pulsed laser 10. The spectrograph 12 counts the number of impinging particle fragments and detects and measures the mass and generation rate of both positive and negative ions that are produced when the particles come into contact with a maser beam. The mass of the particles depends on the time required for the particle fragments to come into contact with the spectrograph 12. The generation rate of the ions depends on the charge imparted by the fragment particles. Signals output from the spectrograph 12 are recorded on a digital oscilloscope 16. The signals digitized are analyzed by a calculator 22 and displayed.  The calculator 22 converts the data into usable data about the chemical properties and concentrations of materials in the particles, the chemical properties and concentration of the particles, and the size of the particles.

Abstract: PURPOSE:To record with favorable image quality even in the case of a high driving force or a high-resolution head, by a method wherein the width of pulses impressed on each heating resistor is controlled to an appropriate value determined in consideration of the past thermal hysteresis for each printing dot. CONSTITUTION:A calculating circuit 6 forms information for each printing dot from an image signal S inputted together with a time series of luster scanning. A temperature predicting calculating circuit 6b for calculating the heat accumulation condition of each heating resistor by using a three-dimensional heat conduction equation performs calculations for predicting the temperature in the next period from the combination of the temperature stored in a temperature memory 6d and the width of an output pulse from a pulse width calculating circuit 6a, and the calculated value is stored into the memory 6d through a one- period delay circuit 6c. Using the temperature dependence of a color former and the three-dimensional heat conduction equation, the circuit 6a calculates an optimum heating pulse width in consideration of the thermal hysteresis from the temperature stored in the memory 6d and the image signal S, and controls the width of the heating pulse impressed on the heating resistors, based on a heat conduction theory.
