Title: Internal combustion engine-driving generator
Inventor: OSADA MASAHIRO
IPC: H02M3/155
Filed: 1986-01-21
Abstract: PURPOSE:To prevent a generator from entering an unstably operating range by limiting the stepup ratio of a chopper type switching regulator to a predetermined value corresponding to an output voltage. CONSTITUTION:The output of a generator 1 is rectified by a rectifier 2, then smoothed, and stepped up by a chopper type switching regulator (regulator) 3, and supplied through an inverter 4 to a load. The stepup ratio of the regulator 3 is determined by the ratio of ON/OFF times of a switching element 6, a pulse-width modulator 5 detects the output voltage of the regulator 3 to control the ON/OFF ratio of the element 6 to maintain it constant. The upper limit of the ON/OFF ratio is determined by deciding a voltage applied to a point (b). Accordingly, the stepup ratio of the regulator is limited to a predetermined value corresponding thereto.

Title: Electrochemical gas sensor
Inventor: YAMAGA NORIYUKI
IPC: G01N27/416
Filed: 1995-01-26
Abstract: PURPOSE: To generate hydrogen on a reference electrode and stably operate the reference electrode by providing a DC power source between the reference electrode and another electrode. CONSTITUTION: When a DC power source 8 is connected between a reference electrode 4 and the fourth electrode 7 and the DC power source 8 is set to the potential generating hydrogen on the reference electrode 4, hydrogen ions in a solid electrolyte film 6 become hydrogen gas, and hydrogen gas is generated. The potential causing this electrode reaction is 0V. The reference electrode 4 is a dynamic hydrogen electrode with the potential 0V, and it has the potential 0V as far as this hydrogen generating reaction occurs even if the surrounding environment is changed in any way.  Since the DC power source 8 is connected between the reference electrode 4 and the fourth electrode 7 and the reference electrode 4 serves as the stable hydrogen electrode, the potential of the reference electrode 4 is not shifted or fluctuated by the effect of the reaction active gas of the surrounding environment and the change of the temperature/humidity atmosphere, and the instability of the output of the sensor sensitivity can be resolved.

Filed: 1993-01-26
Abstract: PURPOSE:To reduce the load of a CPU by inverting the logical level of a signal being outputted presently at each finish of a prescribed time measurement, and transmitting or transmission-stopping the transmission signal in accordance with this logical level. CONSTITUTION:Signal transmitting time and signal transmission stopping time are preset beforehand in a timer 1A by a reload register 2. The time 1A measures the preset time repeatedly, and outputs an overflow signal so at each finish of the measurement of each time. A TF/F 6 inverts the logical level of the signal being outputted presently when the signal So is outputted until the next signal So is outputted. Then, an AND circuit 5 fetches a carrier Cr from the outside and a control signal Sco outputted from the TF/F 6, and transmits them when each of logical levels of the carrier Cr and the signal Sco is 'H' and transmits a signal Tc to stop the transmission when it is 'L'. Accordingly, the start of the start of the output and the start of the stoppage of a remote control transmission code signal can be executed automatically without depending on signal processing by the CPU.

Title: Apparatus for preventing vibration of printer
Inventor: FURUHASHI YOSHIHISA
IPC: B41J29/06
Filed: 1986-01-23
Abstract: PURPOSE:To suppress the vibration of a printer, by restricting the separation part of a leaf spring over the whole thereof in a horizontal lateral direction to regulate the effective length of the leaf spring as a spring. CONSTITUTION:Each half spring 2 is held between clamp plates 10, 10 which are, in turn, mutually clamped by screws 11 to be fixed to the leaf spring 2. Said clamp plates 10, 10 and screws 11 constitute an effective length regulation mechanism and the effective length of the leaf spring 2, which is restricted in such a state that the separation part thereof is held at the predetermined height position thereof between the clamp plates 10, 10 over the whole thereof in a horizontal lateral direction, is two times the length (l) from the lower edge of each clamp plate 10 to the mount part in the lower side thereof because both of the outside separation part 3 and center side separation part 4 of the spring come to a part of the effective length of the spring. When there is difference between the frequency f0 of the reciprocating motion of a printing mechanism part and the inherent frequency f1 of a dynamic vibration reducer, if the length of the leaf spring 2 is regulated, the inherent frequency of the dynamic vibration reducer comes to f0. At this time, the vibration of the dynamic vibration reducer comes to an inverse phase shifted by 180 deg. from the vibration of a printer main body and the vibration of a printer can be made min. by setting off both frequencies.

Title: Light amplifying method
Inventor: SHIBUYA MAKOTO
IPC: G02F1/35
Filed: 1989-01-20
Abstract: PURPOSE:To reduce the generation of four-light wave mixing by allowing polarization states of each signal light in which frequencies are adjacent of plural signal light in a light amplifying medium to be orthogonal to each other. CONSTITUTION:Polarization states of each signal light in which frequencies are adjacent of plural signal light 3, 4 are allowed to be orthogonal to each other and inputted to a light amplifier 6. Accordingly, in the light amplifier 6, a beat comes not to be generated between the signal light in which frequencies are adjacent, and four-light wave mixing between the signal light in which frequencies are adjacent is not generated either. In such a way, in the case of amplifying simultaneously two signal light, the generation of four-light wave mixing can be suppressed completely, and in the case of amplifying simultaneously three or more signal light, a crosstalk caused by four-light wave mixing can be reduced as a whole.

Title: Method of charging sealed nickel hydrogen secondary battery, and charging device thereof
Inventor: KAWASE YASUSHI
IPC: H02J7/00
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To reduce the conformation, weight and cost of a battery while avoiding the increase in battery internal pressure. SOLUTION: When a sealed nickel hydrogen storage battery regulated in positive electrode is charged, the charging quantity in the end of charging is set smaller than the capacity of positive electrode by a prescribed marginal capacity. The capacity of positive electrode means the theoretical capacity of positive electrode calculated from the active material weight in the positive electrode. Namely, the battery is designed so that it partially has the marginal capacity or a charging reserve even when the theoretical capacity of positive electrode smaller than the theoretical capacity of negative electrode is charged by the charging quantity by charging cycle in the charge of the battery.  Thus, generation of oxide in the positive electrode by overcharge in the end of charge can be significantly suppressed, and the resulting increase in battery internal pressure can be satisfactorily prevented.

Title: Vibration damper for piping or the like
Inventor: FURUYA SHUJI
IPC: F16L3/215
Filed: 1988-01-22
Abstract: PURPOSE:To permit the moderate movement and stably restrain the vibration by arranging a plurality of deforming members made of high plastic material in parallel with each other at right angles to the longitudinal vibration damping direction between a supported body such as piping and a supporting construction. CONSTITUTION:If moderate movement such as deformation due to heat occurs between a supporting construction 1 and a supported body 2, curving deformation at a plurality of deforming members 3 is generated gradually, however, the high plastic deformation also occur so that the deformation resistance is reduced and the relative movement is therefore not prevented. On the other hand, when high speed vibration such as an earthquake is developed in the vibration damping direction, a plurality of deforming members 3 arranged in parallel with each other are moved in parallel so that the degree of the deformation between the deforming members 3 is equalized. Energy is therefore consumed at a lower variation rate to restrain the vibration, whereby stably damping vibration.
