Title: Device for controlling ignition timing
Inventor: ZAIMA TOMIYUKI
IPC: F02P5/155
Filed: 1982-06-29
Abstract: PURPOSE:To always carry out optimum ignition even if the rotational speed of an engine is abruptly changed, by using, in addition to a signal synchronized with the rotation of the engine, a signal having a frequency which is integer times of that of the synchronized signal, for ignition control, so that the originally obtained ignition timing is compensated with the rotational speed of the engine just before the ignition. CONSTITUTION:A first reference signal S1 synchronized with the rotation of an internal-combustion engine and generated from a signal generator 3 which receives an output signal from a pick-up device 2 for detecting the rotational condition of the engine, and a second reference signal S2 having a frequency which is integer times of that of the first reference signal S1 and is generated from a signal generator 4, are delivered to a data processing unit 1 which also receives output signals from sensors 5 such as, for example, those for detecting suction vacuum pressure and intake-air temperature after the output signals are subjected to A/D conversion 6. Further, in this processing unit 1, an ignition signal which is obtained from the first reference signal S1 and the outputs of the sensors is compensated with the rotational speed of the engine which is obtained from at least one signal interval in the second reference signal S2.

Title: Wireless signal transmission system
Inventor: UMEYAMA HIROSHI
IPC: H04L1/08
Filed: 1985-05-25
Abstract: PURPOSE:To improve the reliability of transmission by sending a data pulse signal while keeping the pulse width per bit longer than the width of burst noise so as to correct a bit error over plural bits. CONSTITUTION:A transmission data added with an error check data from a transmission device 1 is sent in a form of a radio signal and a reception section 2a of a receiver 2 receives the radio signal and a signal processing section 2b applies an error check of the transmission data based on an error check data. In this case, a data signal (d) expanding the pulse width per one bit than the width of a burst noise is sent from the transmitter 1. Then even when the burst noise is generated, the bit error in the reception signal received by the receiver 2 due to the burst noise is only 1 bit as shown in figure (e) and the error is not given over plural bits.

Title: Transistor switch circuit
Inventor: TOJIKI HITOMI
IPC: H01L21/822
Filed: 1977-09-21
Abstract: PURPOSE:To reduce the power consumption as well as to ensure a steady switching action for the transistor switch circuit to be applied effectively to the memory and the like, by using the transistor in plate of the diode as the negative feedback element. CONSTITUTION:Negative feedback PNP transistor TrQ4 is provided in order to reduce the fluctuation rate of the TrQ3's amplifier gain due to load ZL down to 1/emitter earth current amplification ratio hFE. As a result, it is extremely easy to avoid saturation of TrQ3 and Q1 through adjustment of resistance R3 and R4. This results in elimination of the extra current flow when the IC is achieved, thus ensuring reduction of the power consumption greatly. At the same time, an easy setting of the non-saturating conditions for Q1 and Q3 means that the steady non-saturating action can be secured even if a slight variance may occur to the value between R3 and R4. Thus, a great stabilizing effect can be secured for the action of the circuit by adding Q4.

Filed: 1982-07-02
Abstract: PURPOSE:To reduce the crack of a plating film generated when said plating film is processed completely or to a large extent, by applying blast treatment to the surface of the plating film on an ordinary molten zinc plated steel plate. CONSTITUTION:After hot dipping is applied to a steel plate by using a usual molten zinc plating bath, the surface of the plating film on one surface or/and both surfaces thereof is uniformly subjected to blast theatment. This blast treatment is carried out, for example, by injecting a powder such as a silia powder (SiO2) by compressed air. The speed of the powder in this case is set to a range of 1.5-5kg/cm<2> as the pressure of compressed air and the powder is obliquely collided with the surface of the plating skiin film at an angle of about 45 deg. with respect to the surface of the plating film at the time of collision thereof because the remaining of the blast powder is effectively reduced. The powder adhered to the plating surface after blast treatment can be simply removed by cleaning the same by compressed air or pressurized water.
