Title: Method of preventing migration in conductor parts of electronics
Inventor: TSURUTA KAICHI
IPC: H05K3/28
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To avoid migration at conductive parts of electronics by coating benzitriazole or benzotriazole deriv. on these conductive parts. SOLUTION: Benzitriazole or benzotriazole deriv. is diluted at 0.05-1 wt.% pref. 1-10 wt.% and applied on conductive parts. When benzitriazole or benzotriazole deriv. contacts Ag or Cu conductive parts of a printed board, these parts are passivated to impede Ag or Cu from eluting as ions in a water soln. and hence if a d-c voltage is applied between the conductive parts, no metal can be deposit to avoid the migration.

Title: Data synchronizer circuit
Inventor: YANAKA TAKESHI
IPC: G06F1/04
Filed: 1988-06-07
Abstract: PURPOSE:To avoid the omission of data by controlling the reset timing of a data compiling part and therefore outputting a data signal accurately synchronous with a clock B signal. CONSTITUTION:The DFF (flip-flop) 2-2 and 2-3 produce the windows for the output signal received from a DFF1-3 at the first rising time point of a clock B signal after a data compiling part 2 is validated. Then the window is produced for the output signal received from a DFF1-4 at the next rising time point of the clock B signal. The window is produced for the output signal received from a DFF1-5 at the following rising time point of the next clock B signal. Then the window is produced again for the output signal received form the DFF1-3 at the following rising time point. Thus the data signals are outputted through AND gates 2-12, 2-13 and 2-14 with repetition of said actions. In this case, the output signals of the DFF1-3-1-5 have the length three time as much as the cycle of a clock A signal. As a result, this output changing point never overlaps the clock B signal and therefore the omission of data can be avoided.

Title: Hydraulic pressure producing apparatus in use of variation in suction pressure of engine
Inventor: ITOU MASAMITSU
IPC: F04B23/00
Filed: 1978-11-16
Abstract: PURPOSE: To provide a simple and trouble-free hydraulic pressure producing apparatus economically, by employing an arrangement in which a piston pump is driven by the use of variation in suction pressure of engine and pressurized oil thus obtained is accumulated in an accumulator.  
     CONSTITUTION: As suction vacuum 2 becomes great and pressure in variable- pressure chamber 5 is resultantly lowered, pressure difference in the variable-pressure chamber 5 and in constant-pressure chamber 7 is increased, so that power piston 4 is moved downward against the force of spring 8. Resultantly, pump piston 9 formed integrally with piston 4 is moved deeply into pump chamber 12 and compresses oil in chamber 12. Oil thus pressurized is made to flow into pressure accumulating chamber 19 of accumulator 16 and used as power source for actuating clutch. On the other hand, when the suction vacuum becomes low, piston 4 is moved upward so that oil in oil tank 13 is introduced into pump chamber 12 through check valve 15 and awaits next compression of piston 9.

Title: Image forming method
Inventor: TAMURA YASUYUKI
IPC: G11B5/02
Filed: 1979-10-31
Abstract: PURPOSE: To ensure a high-speed recording, by performing a simultaneous scanning for several pieces of lines in just one rotation, using several units of recording heads in case of a latent image is formed through a magnetic printer.  
     CONSTITUTION: Several heads 1aW6a are distributed in such way that the successive scanning overlaps partially. The recording head carries out no secondary scanning while recording a picture but performs a step-type scanning when passing through the nonpicture region or has a secondary scanning as if a width-shift were given to the heads 1aW6a each while the magnetic recording substance has a turn. In the case of the latter scanning, the main scanning is carried out for the original reading means with an angle of θ=tan -1  (secondary scanning length during a turn of magnetic recording medium)/(circumference length of magnetic recording medium) to the right-angled direction of the secondary scanning. The picture signal supplied to each head is stored in the shift register with every scan and then sent out in a speed synchronized with the rotation of the magnetic recording medium.

Title: Semiconductor support electrode
Inventor: ARAKAWA HIDEO
IPC: H01L21/58
Filed: 1978-11-20
Abstract: PURPOSE: To hold thermal expansion small and raise electric and thermal conductivity in the direction of electrical current, by providing a copper column as a central part and alternately placing a plurality of copper rings and vortical combined copper carbon-fiber rings around the copper column.  
     CONSTITUTION: Each of combined rings contains about 20W60% by volume of carbon fibers. The number of the combined rings is decided according to circumstances. Copper layers 5A of high electric and thermal conductivity and large thermal expansion and the combined rings 4A of low electric and thermal conductivity and small thermal expansion are located in series with one another in the radial direction but in parallel with one another in the axial direction. The thermal expansion of the copper rings 5A is suppressed by the combined rings in the radial direction. Since an electrical current flowing in the axial direction is blocked by the combined rings from flowing in the radial direction, the electric conductivity is raised. The combined rings intercept heat in the radial direction but conduct heat in the axial direction. Heat transfer is accelerated by lead wires or the like. A good support electrode is thus obtained.
