Title: Antiskid control method for automobile
Inventor: USHIJIMA TAKAYUKI
IPC: B60T8/66
Filed: 1986-12-22
Abstract: PURPOSE:To shorten a brake time during a drop, by a method wherein when wheel speed information inputted from a wheel speed sensor exceeds pseudo-car body speed information, control of energization of both a pressure valve and a pressure reducing valve is stopped during a set time. CONSTITUTION:When abnormality, where a pressure reducing valve continues an opening state and a liquid pressure in a brake device is excessively reduced, occurs and a wheel speed is increased over a pseudo-car body speed, control of a current is immediately stopped. A pressure valve is opened, a pressure reducing valve is closed, a control liquid pressure from a master cylinder is fed to a brake device as it is, and a wheel speed is rapidly decreased to bring a wheel into a lock state. After elapse of a set time, for example, 0.15 sec commencing in a stop of control of a current, control of a current is restored, a liquid pressure in a brake device is started to decrease, and a wheel speed is increased by virtue of a road surface reaction force. When a wheel exceeds a pseudo-car body speed, control of a current is stopped again, and a wheel is brought into a lock state in a similar manner described above. Through repetition of the above motions, a car body is reduced at deceleration approximately similar to a pseudo-car body speed.

Abstract: PURPOSE:To provide action characteristics having no fluctuation by sorting resin moludings by automatic detection of determination parts, and assembling other component parts having part characteristics applicable to the resin mouldings. CONSTITUTION:Using a multi-cavity mould having cuts at different positions for respective cavities provided from an upper edge of a side wall 2 of a base 1, the base 1 is moulded.

A folding means 8 folds it at a center part of a tongue member for a preliminarily set specified angle based on this signal. A movable contact member 13 which is pressed into the base 1 by a press-in means 7 is thus folded for the specified angle, and another component part having a part applicable to it can be assembled. Dispersion in action characteristics can thus be eliminated.

Title: Lead pin
Inventor: SEKINE YOSHIO
IPC: H01L23/50
Filed: 1986-12-22
Abstract: PURPOSE:To prevent the fused silver solder from dripping by a method wherein almost spherical-shaped silver solder is diffused on the curved surface or the recessed part formed on the contact surface of the silver solder member in a lead pin main body through the intermediary of the metal which is used to perform a diffused junction operation easily. CONSTITUTION:A lead pin 1 consists of a lead pin main body 3 and the silver solder member 5 on which a tin-coated layer 6 is formed on the whole circumferential surface, and the lead pin 1 is constituted in such a manner that a spherical member 5 is joined through diffusion to the upper surface 31b of the top part of the main body 3. The main body 3 consists of a head part 31 and a leg part 33, and a circular curved surface 31c is formed on the upper surface 31b of the head part 31. As a result, the original form of the member 5 can be maintained almost as it was, and the member 5 can be jointed by diffusion to the curved surface 31c without fusing. An excellent diffused junction can be accomplished under the lenient process control conditions at a lower temperature when compared with the case wherein silver solder is directly jointed by diffusion. Accordingly, the flowing out of the fused silver solder from the upper surface of the top part of the lead pin main body can be prevented.

Title: Matrix display device

IPC: G02F1/133
Filed: 1988-12-05
Abstract: PURPOSE: To reduce the vertical crosstalk level by reducing the level of a holding signal part supplied from a driving signal generating means in its supplying period. CONSTITUTION: In the succeeding positive edge part of a clock waveform CLK, shift register outputs OP2, OP3 are respectively turned to have a low value and a high value, a succeeding line output V3 is turned to be at a voltage level Vs through a switch S3A and a line output V2 is turned to be at an initial holding level Vh . Since a switch S1A is opened, the input of a buffer A1 is interrupted from all voltage supply lines. Until the switch S1A is closed next by a shift register output OP1 held at a high value up to one field period after the interruption point, the voltage of a line output V1 supplied to a 1st line conductor is controlled by voltage stored in a capacitor C1.  Since one-gain buffers A1, A2,... are constituted so as to have a high input impedance, the voltage of the capacitor C1 is attenuated like an exponential curve by a time constant determined by the capacitor C1 and a parallel register R1. Consequently, the generation of an unrequired vertical crosstalk phenomenon can be prevented.

CONSTITUTION:When a sensor 39 senses the tip of a panel 2, simultaneously a movable roller 32' and a panel 33 start to move, and a temporarily fitting member 16 and a cutter 24 are moved at the same speed as the transferring speed of the pawl. At the state where the temporarily fitting member 16 is held at the tip of the continuous film 6, said member 16 approaches the pawl 2, and the tip of the film 6 is pushed to the front end of the panel 2 and is temporarily fitted, thereby moving and press bonding the panel in the state of the panel 2 being pushed. When the senses 39 senses the rear end of the panel 2, a whole block member 11 is approached to the panel 2 and simultaneously the cutter 24 is rotated and moved, thereby cutting the film. At this time the moving speed of the block member 11 is substantially equal to the running speed of the film 6 before said film is perfectly stuck to the panel 2.

Abstract: PURPOSE:To prevent a power output element from breaking owing to the open circuit of a ground line by turning off the power output element forcibly according to the open circuit detection signal of a circuit which detects a current flowing through the ground line. CONSTITUTION:If an electric conductor which connects the ground terminal GND of an integrated circuit IC to an external ground potential point is disconnected or goes to poor connection in contacting or a wire in the integrated circuit, the output signal of a GND open circuit detecting circuit turns on a switch SW2 provided between the gate and source of a power switch MOSFET Q1 and also turns off a switch SW1 which supplies a source voltage to a voltage boosting circuit. While an internal circuit and the external ground point are connected normally, on the other hand, the switch SW1 is turned on to supply an operating voltage VDD to a voltage circuit and the switch SW2 is turned off. Consequently, the output voltage of a gate discharging circuit is boosted corresponding to a signal which is inputted from an input terminal IN and the Q1 turns on to input the output voltage from an output terminal OUT to a load RL.

Title: Printed wiring board
Inventor: KUMAGAI MOTOO
IPC: H05K1/18
Filed: 1990-11-15
Abstract: PURPOSE:To reduce the size of a pattern without decreasing a mounting strength, by forming lands so that they expand over the size of a reinforcing terminal in a direction opposite to electrical connecting terminals of a printed wiring board on which electrical components are mounted by soldering. CONSTITUTION:Among lands 5 and 9 where a connector 10 is mounted, the shape of the land 9, where a reinforcing terminal 8 is mounted by soldering, is extended towards a direction opposite to the extending direction of an electrical connector terminal 10a. The lands 9 extended to the side liable to exfoliation due to a stress generated orthogonal to the thicknesswise direction of a substrate 1 (horizontal direction), acts to reduce the stress. Eventually, there is only left a stress in the direction of the thickness of the substrate to be overcome, and hence, the size of the pattern can be reduced without decreasing the mounting strength.
