Filed: 1984-07-02
Abstract: PURPOSE:To restrict falling off of hydrogen occluding material due to occlusion and ejection of hydrogen and consequent reduction of mechanical strength and conductivity by providing hydrogen occluding material of a specific component in a hydrogen occluding electrode. CONSTITUTION:A reference battery D having a negative electrode in which Ca0.3La0.7Ni5 is used as hydrogen occluding material suffers from pulverization of hydrogen occluding alloy powder due to occlusion and ejection of hydrogen in the negative electrode at discharging and charging, resulting in abrupt reduction of the capacity.

Title: Pulse receiving circuit
Inventor: KOZUKA SEIICHIROU
IPC: H04L7/04
Filed: 1979-10-25
Abstract: PURPOSE:To ensure the reception of the information signal with the correct clock, by selecting automatically the clock phase which can regenerate the information signal without error out of the n-phase clocks generated from the network synchronous oscillator. CONSTITUTION:The appropriate phase phii is selected among the n-phase clocks in the initial state, and the information signal is read by the selected clock of phii and through the FF17. On the other hand, the information signal is read in the FF18 with the clock obtained by giving a slight delay to the clock of phii. Then a comparison is given between the both signals through the FF19 and 20, and the coincidence is decided for these outputs through the exclusive logic sum circuit 22. Thus the read-in of the phase phii is continued in case a coicidence is obtained; while the new phase phij is selected through the selector 13 and the counter 14 when no coincidence is obtained. In this way, the information can be received with the correct clock.

Title: Crystal oscillator for clock
Inventor: SANO NORIHIRO
IPC: C01B33/12
Filed: 1977-11-15
Abstract: PURPOSE: To improve frequency-temperature characteristic by invasion dissolving more than one kind of impurity element into artificial crystal and to maintain conventional accuracy without requiring temperature compensating capacitor.  
     CONSTITUTION: Artificial crystal where more than one or two kind of impurity element such as Al, P, Ti, V, Cr, Mu, Fe, Ni, Cu, Ga, Ge, As, Se, Sr, Zr, Nb, Ta, W, Bi are invasion dissolved is grown by selecting the solution, growing condition, particularly growing temperature, pressure and differential temperature properly. As increasing impurity density, the solid solution changes from replace type to invasion type and the temperature characteristic becomes insensible. Since the temperature fluctuation of frequency is also reduced in the invasion type, tuning fork type vibrator made of invasion type artificial crystal has temperature fluctuation of frequency lower than 5 ppm under the temperature of -10 -50°C, thereby monthly error below than 10 sec can be achieved without requiring temperature compensating capacitor.

Title: Image forming device
Inventor: TAKEUCHI MAKOTO
IPC: H01L33/00
Filed: 1992-05-28
Abstract: PURPOSE:To shorten the turn-off time of a switching transistor by constituting the switching transistor at two steps and using a clamping means such as a clamping diode. CONSTITUTION:When input information VDO is at a high level, switching transistors 3, 4 are turned on, and a light-emitting element 2 is turned off. When the VDO is at a low level, the switching transistors 3, 4 are turned off, and driving currents 1 are made to flow through the light-emitting element 2. Since collector voltage is clamped at approximately 1.3V when the switching transistor 3 is turned on (the VDO is at the high level), saturation is shallowed in the transistor 3, and high-speed switching having a short turn-off time is enabled. Since the anode potential of the light-emitting element 2 is also clamped through a diode 5, the internal capacitance of the light-emitting element 2 and delay by injecting charges to a capacitor 7 can be shortened when the VDO changes from the high level to the low level.
