Title: Automatic clear circuit
Inventor: SHIN YASUHIRO
IPC: H03K17/22
Filed: 1982-11-15
Abstract: PURPOSE:To obtain a miniature automatic clear circuit by forming a series circuit with p and n type MOSFETs and a resistance between high and low potential terminals are making use of the threshold value of the MOSFET. CONSTITUTION:A p type MOSFET5 and a resistance 6 are connected at a point E in series between a high potential input termina VDD (point D) and a low potential terminal G. While a resistance 8 and an n type MOSFET7 are connected at a point F in series between the point D and the terminal G, and the point F is connected to an output terminal 9. At the same time, the point E is connected to the gate of the MOSFET7. For an MOSFET5, the gate and the drain are connected to each other and the source is used as an anode with the gate and the drain used as a cathode respectively. While the point D has no potential, both FET5 and 7 are turned off with the terminal 9 set at L level respectively. When a power supply is applied, the FET5 is not turned on until the threshold value is reached VS. While, the terminal 9 is set at H level through the resistance 8. When the level exceeds the value VS, both FET5 and 7 are turned on with the terminal 9 set at L level. In such a way, it is possible to obtain a simple circuit constitution which needs no external capacity element.

Title: Shift shock reducing device for automatic transmission
Inventor: SUZUKI HOSEI
IPC: F16H61/10
Filed: 1989-07-29
Abstract: PURPOSE:To secure good shift feeling by providing a shift shock judging means, a shift time judging means, and an accumulator pressure correction quantity learning means correcting an accumulator based on the length of the shift time when a shift shock occurs. CONSTITUTION:For shift control, a vehicle speed V is D/A-converted, acceleration alpha is calculated by differentiating the vehicle speed V, the peak value alphap of acceleration and target acceleration alphad are compared, and it is judged that a shift shock occurs if alphap>alphad. The shift time is judged by comparing the shift time Ts until the shift shock occurs after the shift start and the target shift time Td. If Ts<Td at a quick shift, the accumulator pressure is decreased by the correction quantity - P, the engagement of a shift clutch 1 is delayed, and the shift shock is corrected to a low shift shock. If Ts<=Td at a slow shift, the pressure of an accumulator 10 is increased by the correction quantity  P, the coupling of the clutch 1 is accelerated, and the shock is reduced.

Title: Video signal recording and reproducing device
Inventor: AKI SHINICHI
IPC: G11B20/02
Filed: 1986-08-26
Abstract: PURPOSE:To stabilize a PLL circuit and to prevent a timing deviation between a luminance signal and a chrominance signal by prohibiting the actions of a phase comparator in a specified period with the aid of a signal referring a vertical synchronizing signal. CONSTITUTION:A reference signal (a) becomes discontinuous in a head switching position. Since the head switching position is always constant, a vertical driving signal is used to detect it so as to input in a control circuit 14. The control circuit 14 outputs a signal(g) which prohibits the actions of the phase comparator 16 of the PLL circuit in the specified period before and after switching the head and also outputs a pulse (f) which switches a switch 21 in the specified period to convert the reset pulse of one Nth divider 19 into the signal based on the signal obtained by delaying the reference signal (a) in a delay circuit 20. Thus, since an error signal C is not outputted, the PLL circuit is not disturbed and the timing between the luminance signal and the chrominance signal are hardly deviated.

IPC: C25D1/08
Filed: 1982-11-12
Abstract: A screen skeleton as a cathode is subjected to a pulsed current for depositing metal from an electrolytic bath onto the metal regions of the screen skeleton, said electrolytic bath containing a brightener of the second class. This process involves growth of metal substantially perpendicular to the screen skeleton surfaces thus maintaining the size of the openings of the screen skeleton. Small pulse current durations are advantageous. Preferably a pulsed current is used comprising pulse current and non-pulse current durations; more preferably the pulse current durations are subdivided into small pulse current and non-current pulse periods.

Succeedingly, as required, welded workpieces including the buildup-weld zone undergo stress relieving treatment. According to this treatment, coarse grain structure of the heat affected zone is atomized, and impact-resisting properties of the heat affected zone can be improved.

IPC: F24F6/00
Filed: 1994-08-24
Abstract: PURPOSE: To obtain a heater type humidifier which can prevent invasion of scale into a bottom hole of a humidifying tank. CONSTITUTION: In a heater type humidifier equipped with an external case 1, a humidifying tank 2, a heater 9 heating water in this humidifying tank 2 so as to generate vapor and a level gage 11 indicating a water level inside the humidifying tank, a bottom hole 51 is formed in a bottom plate 2b of the humidifying tank 2 and the level gage 11 is made to communicate with this bottom hole 51. Since the construction is so made that the circumference 51a of the bottom hole 51 projects from the surface of the bottom plate 2b of the humidifying tank, the circumference 51a of the bottom hole functions as a dam and prevents scale deposited on the bottom plate from being precipitated and deposited inside the bottom hole. Thereby a passage of the level gage 11 communicating with the bottom hole 51 is prevented from being closed up by the scale.

IPC: H03J5/08
Filed: 1981-12-14
Abstract: PURPOSE:To avoid frequency shift due to the position shift of a memory slide, by tightening a setting plate from the tip of a crossarm. CONSTITUTION:A tightening force to a setting plate 21 is released by taking out a push button 27 this side from a crossarm 20.

As a result, an interval L of the lever 26a is narrowed, a drum 25 is tightened from the surrounding and the setting plate 21 is fixed on the crossarm 20. Thus, a memory slide 23 is moved laterally with the setting plate 21, allowing to avoid the frequency shift.
