Title: Valve system of internal combustion system
Inventor: SHIBATA MITSUHIRO
IPC: F01L1/12
Filed: 1989-05-10
Abstract: PURPOSE:To reduce air consumption while making sufficient lubrication between a valve stem and a sleeve by affording communication between a relief path and an air pressure chamber below the liquid level of a predetermined amount of reversed lubricating oil and in a position above a guide hole. CONSTITUTION:A relief valve 30 is set to be opened with valve opening pressure corresponding to the maximum pressure in an air pressure chamber 13 when a predetermined lubricating oil is reserved in the air pressure chamber 13. The relief valve 30 is connected to the air pressure chamber 13 through a relief path 31 drilled in a sleeve 10 to communicate to the the air pressure chamber 13 below the oil level l of a predetermined amount of reserved lubricating oil in the air pressure chamber 13 and in a position above a guide hole 10b. Thus, the lubricating oil is expelled mainly by opening the relief valve 30 and the level of the lubricating oil is not lowered below the guide hole 10b. Thus, the useless discharge of air from the air pressure chamber 13 is avoided while lubricating oil needed to make lubrication between a valve stem 5a and a sleeve 10 can be reserved in the air pressure chamber 13.

Filed: 1986-05-20
Abstract: PURPOSE:To detect variations in the height and inclination of a flat plate body at the time of the movement of the body by providing two half-mirrors nearby the reference surface and projecting light, and finding the position where its reflected or transmitted light passes through the reference surface. CONSTITUTION:A light beam L is incident on a half-mirror 2 and reflected light from the flat plate body 4 is reflected by a half-mirror 3, so that the position P1 where the light travels backward and passes through the reference surface S is measured. Further, the position P2 where the light transmitted through the mirror 3 passes through the surface S. Then when the body 4 moves to the 2nd position, the position P11 where the reflected light from the body 4 passes through the surface S and the position P21 where the light transmitted through the mirror 3 passes through the surface S are measured. Then, variation DELTAthetain angle and variation DELTAd in height throughout the movement of the body 4 are found from DELTAtheta=d/8l<2>XP1P11 and DELTAd=(P2P21-2DELTAthetal<2>/d)Xd/2l (d: distance between the body 4 and surface S, l: distance between the body 4 and point P1). Thus, the height and inclination of the body 4 are measured easily and accurately.

Title: Cathode clamping type dc restoration circuit
Inventor: ISOBE AKIO
IPC: H04N5/18
Filed: 1985-05-31
Abstract: PURPOSE:To lower fluctuation of black level caused by the fluctuation of video pattern by using voltage the value of which is controlled by magnitude of discharge current. CONSTITUTION:When a switch SW is closed, IA and IB flows in inverse proportion to RA and RB, and discharge current Idc flows as nearly sum total of them. Accordingly, when set to RA>>RB, greater part of Idc flows to Q2, and collector current of Q1 goes to small and base current of Q1 also goes to small. Consequently, apparent internal impedance goes to small. Further, Rd, Rf flow controlling current If, and generate control voltage in RE. Idc flows virtually in Rd by setting. Between the emitter and base of the Q1 can be as nearly constant and controlling current that flows in RE is inversely proportional to the ratio of Rd to Rf. Consequently, stable control can be performed.

IPC: G06F12/00
Filed: 1988-05-16
Abstract: PURPOSE:To speed up writing to a buffer by starting an address decoder and a memory controller in parallel and shortening the time required for decoding apparently. CONSTITUTION:A central processing unit (CPU) 1 activates a start signal (ADS) 8 and places a signal (WR) 9 in a write ready state, the memory controller 2 predicts the timing one cycle before the wiring to the buffer 4 is finished when a signal (MSREQ) 14 becomes active and makes an access end signal (MSRDY) 16 active. When the address decoder 12 makes the MSREQ 14 active, the MSRDY 16 is sampled at this point of time and synchronized by a flip-flop 19 to make the signal (RDY) 10 active. When the MSREQ 14 does not become active, the MSRDY 16 is not sampled, so the access of the CPU 1 with the MSRDY 16 is never finished. Consequently, the memory access is speeded up.

Abstract: PURPOSE: To enable the execution of high-speed and stable determination of a nondefective and a defective without stopping an object of inspection, by irradiating the object of inspection, in rotation in linkage with a turntable, and by leading an irradiating light to a light-receiving window. CONSTITUTION: Light of a light source 41 is passed through optical fiber groups for projection of fixed and rotary optical guides 10 and 11 and cast on an object 13 of inspection supplied sequentially onto a turntable 12 rotating continuously. When the guide 11 rotates with the table 12 and the end face of an optical fiber group for light reception on the upper side comes to the position of a light-receiving window 17 on the lower side of the guide 10, only a reflected light from the object 13 opposite to the lower end face of the optical fiber group for reception is inputted to a photodetector 42 through the optical fiber group 16 for reception and amplified 43 and outputted.  When the object is a nondefective 13A (a defective 13B), an output level is lower (higher) than a threshold level SH and the quality of the object 13 is determined on the basis of this comparison of the levels. On the occasion, the reflected light is measured for a time corresponding to a distance S of the window 17, and when the measurement is ended, a reflected light from the subsequent object 13 penetrates into the window 17. In this way, the execution of high-speed and stable determination of the nondefective and the defective is enabled without stopping the object 13.

Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To reduce containers with a defective capping which occurs right after the start of the operation of a capper by reducing the number of caps to be accumulated in an accumulating section as much as possible. SOLUTION: Caps, not shown in the Figure, are heat-sterilized by a sterilizing device 3, and then, temporarily accumulated in a accumulating section 15, and then, capped on a container 11 by a capper 5. A control device 17 controls the operation of a first stopper 12 so that the caps may be fed to the sterilizing device 3 when a signal from a container sensor 16 for the existing of the container 11, is input. By this method, the number of the caps which are accumulated in the accumulating section 15 can be reduced than a conventional method. Thus, the number of defective containers which generate by the attaching of the cap which has been cooled to a normal temperature while waiting in the accumulating section 15, to the container 11, right after the start of the capping, can be reduced.
