Title: Pneumatic pressure type booster
Inventor: ENDO MITSUHIRO
IPC: B60T13/573
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To provide desired braking force by clearly prescribing a boosting rate switching point in a pneumatic pressure type booster with built-in reaction adjusting mechanism. SOLUTION: A reaction adjusting mechanism 42 is installed between the plunger 25 built in the valve body 17 of a power piston and the reaction member 34 arranged in front of the valve body 17. The reaction adjusting mechanism 42 comprises a compression spring 45 installed between a reaction receiver 43 and a restraining member 44 at a specified set load. The compression spring 45 is contracted in emergency brake operation by setting the set load of the compression spring 45 in the boundary range between the input in normal brake operation and input in emergency brake operation, providing higher boosting ratio for reducing input in a large output region.

Title: Exclusive call system of station to be controlled in plural control stations
Inventor: KONISHI OSAMU
IPC: H04W92/04
Filed: 1984-02-17
Abstract: PURPOSE:To improve the efficiency in system operation by designing the system that a corresponding station to be controlled is selected by one operation according to the predetermined order in mobile communication to prevent waste of time for recalling. CONSTITUTION:The operation is started at a point of time (1) at first, and in order to check whether or not a common control line 3 is occupied by a signal of other station, master stations 2'-1 and 2'-2 check the presence of the occupied signal at a point of time (2) by using an occupied signal detecting circuit 16. Then a time T1 is elapsed and the occupied signal is transmitted again from the master station 2'-1 at a point of time (5). When a time T2 is elapsed after that, an occupied signal detection circuit 16 of the master station 2'-2 detects the occupied signal of the master station 2'-1 so as to stop the transmission of the succeeding occupied signal. As being known the operation of an example of the execution, a master station only having a short occupied signal stop time selects a base station in the master stations making a call by giving a difference as T2-T1 to the time interval between the 1st and 2nd occupied signal transmitted from each master station.

Filed: 1984-02-17
Abstract: PURPOSE:To reduce an insertion loss, and to execute an amplification, too, by constituting so that an amplification characteristic of a semiconductor junction element and a stopping characteristic by a reflecting film are used as an optical demultiplexing element. CONSTITUTION:An optical branching circuit 1 is provided with semiconductor p-n junction elements 2-1, 2-2,..., 2-n for amplifying an optical signal, output optical waveguides 3-1, 3-2,..., 3-n, and reflecting films 4-1, 4-2,..., 4-n whose reflection factor becomes larger in a long wavelength area than a wavelength of the optical signal which is made to pass through by the semiconductor p-n junction elements 2-1, 2-2,..., 2-n, respectively. As for this reflecting film, for instance, by a dielectric multilayer film, the reflecting film provided with each desired reflection factor characteristic is obtained easily. In case an optical signal is made incident on the p-n junction element 2-i provided with such a reflecting film, as for light of a short wavelength side from lambdai, the optical signal is attenuated greatly by an absorption in the p-n junction element 2-i. As for the signal light whose wavelength is lambdai, it is amplified and emitted since the gain exists.

Filed: 1990-02-06
Abstract: PURPOSE:To prevent the degradation in the relative accuracy by forming a pseudo load capacitive element of one capacitive element group among plural elements the same as a D/A converter section and using the element as a charge redistribution type D/A converter section. CONSTITUTION:When, e.g. the characteristic does not meet the standard, a selective signal phiS is changed to be logic '1', then a 2nd D/A converter is selected in place of a 1st D/A converter and connected to the inverting input of a comparator 1. Then the operation having been implemented so far by switches S1-S4 is taken over by switches S5-S8 and the operation having been implemented so far by the switches S5-S8 is taken over by the switches S1-S4 conversely. Thus, capacitive elements C5-C8 having been connected so far to enhance the common mode signal rejection ratio of the differential input are replaced for the level generation of the D/A converter and the capacitive elements C1-C4 of low accuracy are replaced for pseudo load to reduce the defect rate remarkably.
