Title: Asynchronous transfer circuit with transfer speed switching function
Inventor: NASU YASUYUKI
IPC: G06F13/38
Filed: 1995-03-15
Abstract: PURPOSE: To quickly transfer data without overflowing receiving data of a device on a reception side in a transfer circuit executing data asynchronous transfer from a high speed device to a low speed device. CONSTITUTION: Data stored in a sending data storing buffer 1 is read to a sending data storing register 2 by the instruction of a sending data storing buffer reading address register 30, and transferred to the device on a reception side. When a data transfer instruction signal generation circuit 7 generates a data transfer instruction signal, a sending stage initial value selectively obtained with a value set to a receiving-side device speed instructing register 40 from among plural constant values determined in advance is set to a sending stage display register 50 and counted down one by one every clock cycle. When the value in the sending stage display register 50 becomes the previously determined constant value, 1, e.g. the sending data storing buffer reading address register 30 is counted up.

Title: Paper-feeding device for copying machine and the like
Inventor: ISHII YASUAKI
IPC: B65H1/26
Filed: 1979-05-07
Abstract: PURPOSE: To enable stabilized feeding of sheets by providing the tip part of a cassette with a sheet-aligning member standing straight at the bottom plate of the cassette and moving from the position where the front edge of sheet comes into contact therewith to that for escape out of the passage of the fed paper.  
     CONSTITUTION: A sheet-aligning member 8 standing straight against a bottom plate 4 is positioned on the side slightly lagged from a corner pawl 9a. And the corner pawl 9a is devised so that it hold both corners of the front edges of the loaded sheets down to the lowest-positioned sheet. In addition, the engagement part 11 of the lower end part of the sheet-aligning member 8 is projected from the lower surface of the bottom plate. When a cassette is moved in the direction of an arrow (a) under the condition, the engagement part 11 strikes against an engagement member. And, since the engagement part 11 makes rotational movement, the sheet- aligning member 8 escapes from a guide plate 6 and housed in the concave 6a of the guide plate 6. In this way, the sheet-aligning member is devised not to project from the guide plate, thus the sheets being fed in a stable condition.

IPC: F02M47/00
Filed: 1991-02-28
Abstract: PURPOSE:To secure the superior combustion even in the case where the fuel injection timing is delayed largely in the exhaust gas countermeasure, by shortening the injection period. CONSTITUTION:As for a fuel injector, at least a straight passage part 28A is formed in a feeding passage 28 for the communication between a high pressure chamber 22 and a pressurizing chamber 23, and a controlling needle valve 10 for opening and closing the feeding passage 28 by the hydraulic pressure for the energization to the high pressure chamber 23 has a tapered part 29T for the application of the valve opening pressure and a straight part 29S fitted with a straight passage part 28A. Since the feeding passage 28 is opened after the lift of the controlling needle valve 10 becomes over a prescribed value and each pressure in a control chamber 18 and the high pressure chamber 23 rises sufficiently, the pressure in the pressurizing chamber 22 rises sharply, and also the pressure in an injection chamber 7 rises sharply. Accordingly, the injection period due to an injection hole 1 can be shortened.

Abstract: PURPOSE: To eliminate a large-capacity resistor from an operation test circuit for making compact a circuit configuration, and reduce power consumption by diverting current flowing in a power indication circuit, and feeding the current to a zero-phase AC machine as test current for performing an operation test. CONSTITUTION: When the operation test of an earth leakage breaker is implemented, the moving contact shoe 90A of the C contact 90 of an operation test circuit 80 is changed over to the stationary contact shoe 90C thereof, thereby causing the indication current Is of a power indication circuit 11 to flow across a zero-phase AC machine 42. Then, the current Is is detected with a zero-phase current transformer 4 and an earth detection circuit 7 is also operated. Then, the proper operation of the breaker is confirmed, depending on whether a breaking section 3 can break main power bus bars 1 and 2. According to this construction, a large-capacity resistor can be eliminated from the test circuit 80, thereby making compact the breaker, and reducing power consumption. Also, the breaker can be protected from being burnt, due to an erroneous connection.
