Title: Directly-coupled condition transfer drive connecting device in friction continuously variable transmission
Inventor: KASHIWABARA TADASHI
IPC: F16H61/08
Filed: 1989-05-06
Abstract: PURPOSE:To utilize the easiness of decoupling at the time of being placed in a condition with no influence thrust for the goodness of disconnecting action in a device by constituting easily decoupled trapezoidal pawl clutches and providing constitution in such a way as eliminating the easiness of decoupling by a hydraulic cylinder of relatively small thrust. CONSTITUTION:When a synchronously rotational condition between rotary speeds of input and output side rotational elements 1, 2 and a condition, in which a car speed reaches not less than a preset value, are both established, a single-acting hydraulic cylinder device 9 operates to make a directly coupled condition in which the output side rotational element 2 is drive-connected to the input side rotational element 1 through trapezoidal pawls 1a, 2a, and this condition is maintained. Since this input side rotational element 1 is engaged with the output side rotational element 2 by engaging sloped surfaces with each other through the trapezoidal pawls 1a, 2a under a condition of disconnection convenience, when an operating chamber 11 in a hydraulically operated system including the single-acting hydraulic cylinder device 9, communicates with an oil discharge side, transmission of power is promptly returned to a condition where a speed change is driven through a friction continuously variable transmission.

Title: Demodulator for plural carrier waves
Inventor: MORIYA YOUICHI
IPC: H03D3/00
Filed: 1977-09-22
Abstract: PURPOSE: To regenerate the demodulation signal of each channel and to simplify the constitution for the SCPC/FM system, by switching the local oscillation frequencies in sequency to perform sampling corresponding to each carrier wave.  
     CONSTITUTION: The output signal of reference signal oscillator 51 is converted to the code switch pulse of 96k Hz at control pulse generator 50 and then applied to code transmitter 49. Then 12 sets of frequency setting codes are supplied in sequence to frequency synthesizer 36, and the output demodulates (3) the modulated waves sequentially for the 12 channels of terminal 1. And each demodulation output is sampled and reserved in circuits 52∼63 from circuit 50 via pulse (c), and then each sampling value is regenerated to the demodulation signal through LPF64∼75 to be delivered via amplifiers 76∼87. As a result, the demodulation becomes possible with one unit of the demodulator containing the frequency converter and the synthesizer for local oscillation each, thus simplifying the constitution

Abstract: PROBLEM TO BE SOLVED: To efficiently perform strict synchronization update of data. SOLUTION: Exchange is performed between a server 2 and a reception terminal 5 in accordance with a protocol which modifies a two phase commitment protocol and data update is executed. That is, in the server 2, an update inquiry whether or not the data are updated is transmitted to plural terminals including the reception terminal 5 and a response to it is received. Furthermore, at a specified time, tabulation of responses to the update inquiry is performed and, on the basis of the tabulation, it is decided whether or not the update of data is performed, and the decision is transmitted to the plural terminals. On the other hand, in the reception terminal 5, the update inquiry from the server 2 is received and a response to it is transmitted.  Then, when it is transmitted as a response to the update inquiry that the update of data is not performed, if the decision to the effect that the update of data is performed is received from the server 2, an access to the data of an update object is defrozen.

Abstract: PURPOSE:To activate a catalyzer at an early stage without damaging idle drive performance and fuel consumption by enumerating basic delay angle amount of ignition timing and correcting it in correspondence with opening of an idle control valve and elapsed time after starting at the time of idle drive after an engine starts. CONSTITUTION:When a drive condition detection means 1 detects a drive condition, a basic ignition timing enumeration means 2 enumerates basic ignition timing in accordance with it. In the meantime, a basic delay angle amount computing means 3 enumerates basic delay angle amount of the ignition timing required for activation of a catalyzer from cooling water temperature at the time of starting. Thereafter, a correction value computing means 4 computes correction value of the basic delay angle amount from opening of an idle control valve to increase air by way of by-passing an air suction throttle valve. Additionally, in parallel with it, a correction value computing means 5 computes the correction value of the basic delay angle amount in accordance with elapsed time after starting. Thereby, an idle delay angle amount enumeration means 6 enumerates idle delay angle amount by way of correcting the basic delay angle amount in accordance with both of the correction values, and the basic ignition timing is adjusted by basic ignition timing adjustment means 7.
