Title: Information signal processing circuit
Inventor: YAMASHITA NORIYUKI
IPC: H04N5/16
Filed: 1985-06-18
Abstract: PURPOSE:To obtain an appropriate frequency modulation signal based on an information signal from a frequency modulator circuit by controlling the DC level of the information signal supplied to a pre-emphasis part from a level clamp part in accordance with a control signal from a control signal forming part. CONSTITUTION:When a video signal Sv is supplied to an input terminal 11, the level clamp part 12 acts so as to clamp the video signal Sv at the prescribed DC level, and the video signal where a pedestal level is clamped at a DC level Vp can be obtained at an output terminal. Receiving a differential detection signal Sc from the control signal forming part 19 as the control signal, a DC level control part 13 controls the pedestal level of the video signal Sv supplied to the input terminal of the pre-emphasis part 14 according to the level. As a result, the pedestal level of an output signal Sv' from the pre-emphasis part 14 is equalized to that of the video signal from the level clamp part 12, that is, the DC level Vp.

Inventor: FUKAMACHI MAKOTO
IPC: H01R13/64
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous fitting between a hood part of a male side connector housing and a female side connector housing.

Title: Heat storage tank
Inventor: NAKAMURA SHUJI
IPC: F24F5/00
Filed: 1988-05-30
Abstract: PURPOSE:To prevent a water proof tank from hanging down or breaking down, by installing a drain trap which allows bedewed water alone to be discharged to a ceiling part of a heat storage tank which is insulated and water-proofed, but inhibits the back flow of steam or the like from said tank. CONSTITUTION:Bedwed water drops into a main body 11 of a drain trap 10 from joint parts 8 of insulated and water-proofed panels P and remains in a sump 15 by way of an inflow pipe 14 and is consecutively discharged by the inflow of new bedewed water into a heat storage tank from a waste water port 13 by way of a waste water pipe 14. Since the water level in the sump 15 is designed to keep a regular level in the upper end of the waste pipe 14 all the time, the lower end of the inflow pipe 12 is maintained to be under a submerged state, which makes it possible to prevent the back flow of the steam or the like to the upper part of a shielded plate 16 even when the steam should enter the main body 11 of the drain trap from the heat storage tank by way of the waste water pipe 14. It is, therefore, possible to prevent the penetration of the steam in the heat storage tank into an insulation layer 2 and a concrete tank body 1 and avoid its bad effect produced by the penetration of the steam, and prevent a water proofed layer from exfoliation, hanging down, downward expansion or rupture.

Title: Manufacture of very small ball
Inventor: KIYOTA SHIGEO
IPC: G01R1/067
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a small ball of very-small-diameter which can form a plunger contact in a very small diameter by a method wherein flat rubbing plates which sandwich and hold the very small ball are slid and the small ball is polished. SOLUTION: Small balls 4a of a diameter of, e.g. 0.5 mm are sandwiched and held between a rubbing plate 8 and a rubbing plate 8', the rubbing plates 8, 8' are turned to mutually opposite directions, and the small balls 4a are polished so as to become very small balls in a diameter of about 0.2 mm. It is required that abrasives should be contained in the rubbing plates 8, 8' or that fine powders as abrasives whose diameter is small than that of the very small balls to be manufactured should be put between the rubbing plates 8, 8'. As the abrasives, a diamond, a ceramic for abrasives or the like is used. Thereby, the small balls in a diameter of down to 0.05 mm can be obtained. When the very small balls are used, it is possible to form a plunger contact in a diameter of 0.1 mm.  In this manner, the very small balls which cannot be manufactured in conventional cases are manufactured easily. When the very small balls are used, the plunger contact can be formed so as to have an ultrafine diameter.

Where In quantity becomes 9.5wt% or over, fusing point drops suddenly to result in an unstable state; where it is 7.5wt% or below, thermal fatigue characteristic deteriorates. Then, where quantity of Au, Ag, Ni, Cu in the brazing material 1 is 2wt% or over, an alloy of Sn with them is produced to an easy cracking, thus thermal fatigue characteristic considerably deteriorates. Sn-In brazing material 5 is welded by pressure, heated and fused onto the substrate 2 plated with Ni 3, and the element 4 plated with Au is placed on Ni 3 to junction. According to this constitution, the element 4 is free from break.

Title: Controlling circuit for 2-phase motor

IPC: H02P25/06
Filed: 1980-09-25
Abstract: PURPOSE:To effectively stop a motor instantaneously without offset current by electronically switching to a brake based on the counterelectromotive force of the motor immwdiately before the stoppage of the motor by generating a reverse torque. CONSTITUTION:A stop switch SW is closed at the time t1 to instruct the stop of a motor, thereby setting the output a of the switch SW to low level, the stop command signal g of the inverted output is applied to a transistor TRQ21, which is thus conducted, and the voltage dividing potential between the resistors R4 and R6 becomes lower than the potential at the point B by approx. VBE. Accordingly, the normal rotation signals phi1, phi2 are switched to reverse rotation signals -phi1, -phi2 via the switching circuits of the TR Q6-Q9, Q13-Q16. Therefore, the rotating frequency (c) decreases by the reverse rotation torque, the TR Q46 is conducted by the high level signal (b) of the FF9 due to the high level of the collector output (f) of the TR Q24 at the time t2 when the output voltage (d) of the F/V converter circuit 5 is lowered from the reference voltage VREF, thereby inactivating the differential amplifier 11, and the differential amplifier 12 is activated. In this manner, the counterelectromotive force of the coil W1 is used to perform the braking operation.
