Patent JP-H01265243-A (JP)
Title: Original size detecting method
Inventor: AISAKA SEIYA
IPC: G03B27/62
Filed: 1988-04-15
Abstract: PURPOSE:To surely detect the size of a partial original by detecting size by one of plural original sensors and further detecting original size when all or any of the sensors do not detect size and when an original retainer cover closes. CONSTITUTION:An operator places an original to be copied on an original platen 26. When he places regular size originals of B5 or A4 in a normal position, the original sensor 14 detects that placing and sends a detecting signal to a CPC. A case where only the sensor 14 detects means that the original size is B5. When a partial original is not placed in a normal position, outputs from the sensors 11, 12, 13 and 14 do not change. As the original retainer cover begins to close, a sensor supporting frame 15 moves to change the outputs from the sensors 11, 12, 13 and 14. Therefore, their signals indicate the original size. When the partial original 34 is placed near the central part of the platen 26, the sensor 14 outputs a signal as long as the supporting frame 15 is within an area A or B, and the signals indicate that the size is A4, which is displayed. The operator realizes how a copying machine judges the practical original in real time, which is an advantage of this method.

Title: Hydraulic weighing device
Inventor: KAMIMURA OSAMU
IPC: G01G19/02
Filed: 1979-07-26
Abstract: PURPOSE: To assure the stability of a pointer, by providing buffers as vibration- proof means in fluid passages, which are connected to cylinders containing pistons which support a weighing table, to block pressure waves transmitted from pressure reception pipes.  
     CONSTITUTION: Buffers 9 shaped as stepped rods are provided in fluid passages 3AW3D to prevent impulsive pressure waves from being transmitted from pressure receiving sections 1 to a load meter 7 through pressure reception pipes 4 and a connector 3. Each buffer 9 comprises a part 9A of outside diameter smaller than the diameter of a hole 3a 1  and another part 9B screwed in a tapped hole 3a 2 . A thin passage 9b, which extends in a radial direction and communicates with another passage 9a, is opened in the peripheral surface of the part 9A. The hole 3a 1  and tapped hole 3a 2  of the fluid passage 3A communicate with each other only through the passages 9a, 9b. According to this constitution, strong impulsive pressure waves transmitted from the interior of the pressure reception pipe 4 are reflected on the end face of the part 9A so that the pressure waves do not enter into the passage 9b. As a result, the dynamic pressure waves are not transmitted to the interior of a pipe 5 for the meter.

Abstract: PURPOSE:To make fuel control accuracy and accelerating responsiveness compatible by changing a fuel supply control system over to such one as based on throttle opening at a time when an actual throttle opening variation is reached to the extent of more than the reference value set so as to become the smaller, the lower in engine temperature. CONSTITUTION:Each detection signal of engine speed out of a distributor 8, engine temperature and throttle opening out of a respective sensors 9, 6, and intake air quantity out of an air flow meter is inputted into a control unit 10. On the other hand, a specified control signal is outputted to each injector 5 of an engine 1 from the control unit 10. At this time, at the control unit 10, a reference throttle opening variation is set so as to become the smaller, the lower in engine temperature. When the throttle opening variation is more than this reference throttle opening variation, a fuel supply control system is changed over to such one based on the throttle opening from that based on the intake air quantity.
