IPC: G06F13/42
Filed: 1992-02-05
Abstract: PURPOSE:To preclude a malfunction due to the absence of packet data or the reception of data by a receiver from halfway data. CONSTITUTION:A transmitter 1 sends out a bus using request signal 9 to a bus using right arbitrating device 8 and then outputs the data and a transfer clock to the packet bus in the case of receiving a bus using permission signal 11. The receiver 3 detects the data 5 on the packet bus being packet data addressed to a present device from the header part of the data, and then receives the data with the clock 6. The receiver 3 continues the sending of an answer signal 7 to the packet bus until the device becomes ready to receive next packet data after data reception processing. The transmitter 1 continues the sending the using request signal 9 until the end of the answer signal 7 from the receiver 3 without ending the bus using request signal 9 immediately after the packet data transmission ends.

Title: Pll radio receiver
Inventor: YOSHIDA MASAYOSHI
IPC: H04B1/26
Filed: 1992-02-05
Abstract: PURPOSE:To emphasize one-action tuning merit due to a preset memory CH key by displaying only the preset memory CH reaching a fixed reception level at a display part. CONSTITUTION:When an area is decided by an area discriminating means 5, a control part 7 calls the frequency group of the relevant area from a frequency memory part 9 by areas. Then, the called frequency group is stored in a preset memory CH part 8 for frequency storage. Afterwards, all the preset memory CH are scanned. Concerning the respective frequencies of this frequency group, a reception level discriminating means 6 judges whether the reception level is higher than the set and fixed level or not. The control part 7 displays the No. of the preset memory CH at a frequency higher than the fixed level by turning it on at a display part 12. Thus, trouble for a user to erroneously set the No. of the preset memory CH not suitable for practical use can be prevented.

Filed: 1987-01-29
Abstract: PURPOSE:To avoid knocking by detecting the acceleration state based on the throttle valve opening or the change quantity of the throttle valve opening and delayingly correcting the ignition timing if the detected acceleration state is in the decreasing direction of the engine rotating speed. CONSTITUTION:A control unit 22 receives detection signals of a crank angle sensor 20, a throttle sensor 30, a pressure sensor 28, etc. and determines the ignition timing with correction for the water temperature or the like. Next, when an engine is in an acceleration state and the engine rotating speed change rate is the preset decreasing rate or higher, a preset value is subtracted from the acceleration correction value, and the ignition timing is delayingly corrected. When the change rate is the preset decreasing rate or lower and subsequently becomes the preset increasing rate or higher on the contrary, a fixed value is added to the acceleration correction value, and the ignition timing is advanced. When the change rate is the preset increasing rate or lower, reduction in lead is not carried out. When acceleration is not detected, the ignition timing is not delayingly corrected. This calculation is performed for every 30 deg. of the crank shaft rotation angle, the ignition timing is corrected, the final ignition timing is determined, and a time-converted ignition timer is activated for ignition.

Title: Stabilizing method for oscillation frequency of laser device
Inventor: KAEDE KAZUHISA
IPC: H01S5/068
Filed: 1988-01-29
Abstract: PURPOSE:To stabilize the absolute value of oscillation frequencies as well as the intervals thereof in a plurality of laser devices, by a method wherein one of resonance frequencies of an optical resonator is so controlled as to coincide with an oscillation frequency of a frequency absolute stabilizing laser device in which the absolute value of the oscillation frequency is stabilized. CONSTITUTION:The laser beam emitted from a semiconductor laser device 1 passes through a Fabry-Perot optical resonator 3 with a scanning mechanism via an optical fiber 3 and is then received by a first photodetector 4. The intensity of the received laser beam is converted into an electrical signal by the first photodetector 4 and the electrical signal is then applied to an optical resonator controlling device 5. In this connection, the optical resonator controlling device 6 adjusts finely the spacing of resonator mirrors in the optical resonator 3 so that the emitted laser beam from the semiconductor laser device 1 in which the wavelength is absolutely stabilized is transmitted, for example, at the point A with respect to frequency. This adjustment is performed by adjusting the applied voltage for a PZT of the optical resonator 3 in response to the output of the photodetector 4. As a result, the absolute stabilization of the point A causes all the resonance frequencies of the optical resonator 3 to be absolutely stabilized, respectively. In addition, for example, the spacing of the resonator mirrors in the optical resonator 3 is adjusted so that the output of the photodetector 4 becomes a maximum, and thereby the resonance frequencies can be stabilized.
