Abstract: PURPOSE:To perform the movement of succeeding characters and picture data accompanied with deletion/insertion of character data on a display screen at high speed, by displaying the characters and picture in mixture through the use of CRT and moving the numeric data of refresh memory. CONSTITUTION:Font data of characters are stored in a CG memory in a character and picture display controller 400. The picture data is stored in an external memory device 700. The picture data is transferred from the storage device 700 to a memory 300 in a DMA. This data is split in mesh into a character font size on the memory 300 with a controller 200 named as image font). This data is DMA-transferred to a separate area from the character font. The address of the data to be displayed is DMA-transferred to a refresh memory in the display controller 400. In the refresh memory, the address in the CG memory of the character/image font corresponds to the display location of the screen and this address is sequentially scanned. The CG memory transmits the font data to the CRT  controller in parallel and the controller transmits the data to a CRT with serial  conversion.

Abstract: PURPOSE:To perform appropriate rear wheel braking force distribution control always by setting the target value of crossover pressure, and up-correcting the target value after the termination of braking when braking deceleration generated before the lapse of the specified time is the specified value or more. CONSTITUTION:In the case of a left rear wheel, the pressure stored in a memory M3 for storing crossover pressure for closing a PCV by-pass valve 26 by-passing the PCV 181 of the left rear wheel is set as the first target value.

Title: Pipe conveyer, and conveying method using it
Inventor: HIRUTA MASAYOSHI
IPC: B65G19/22
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide conveyance of large amount of matters and a long time stable operation, by placing safety against overturning on the back side of a conveyer with facing at least progressing direction of a blade. SOLUTION: A blade 3 consists of a flat elastic blade 21 which has an outer diameter slightly less than the inner diameter of a pipe 1 and a supporting part 22 which supports it. The supporting part 22 is an iron-made blade and its outer diameter is about 70% of that of the elastic blade 21. A safety member against overturning 100 is a bar against overturning and extends diagonally downward, and its top 102 is slightly upward and can be slid easily. Because gap exists between the top 102 and the inner side of the pipe, the blade 3 can tilt a little. Thus, when force impressed to the blade 3 from a conveyed matter causes the blade 3 to tilt, the top of the safety member against overturning 100 contacts with the inner side of the pipe 1 and the blade 3 is prevented to tilt furthermore.

Abstract: PURPOSE:To simplify the arrangement of an article feed device having a conveyer and a star wheel by making the front side of each star wheel pocket flat, and by providing a clutch for engaging and disengaging the star wheel to and from the receiving side and a brake. CONSTITUTION:The forward side part 27 as viewed in the rotating direction, of each article storage pocket 27 of a star wheel 23 is made to be substantially flat, so that articles 6a conveying on a conveyer 22 are smoothly stored in the pocket 27 of the star wheel 23. Further, if a lack of articles upstream of the conveyer 22, overfeed of articles upstream of the conveyer 22 or the like occurs, when one of the pockets 27 of the star wheel 23 comes to a position near to an article receiving/delivering position for a receiving side device 21, a clutch 43 is disengaged to release the coupling between the receiving side device 21 and the star wheel 23, and then the star wheel 23 is stopped by means of a brake 44. With this arrangement, it is possible to simplify the drive system.

Title: Relief valve
Inventor: INOUE EIJI
IPC: F16K3/24
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the line pressure from changing by allowing two hydraulic forces to cancel each other, which act when the working oil passes two valve opening parts. SOLUTION: The B1 chamber as the first chamber always in communication with the inlet port P of a relief valve 40 connected with the discharge line of an oil pump can be put in communication with the first outlet port R1 via the first valve opening part 48A. The inlet port P can be put in communication with the B2 chamber as the second chamber via the second valve opening part 48B. When the working oil passes the valve opening parts 48A and 48B, the forces F1 and F2 generated in a spool valve 44 owing to unbalance of the pressures in the B1 and B2 chambers act in such directions as to cancel each other. Thus the line pressure P'L of the relief valve 40 can be stabilized.

Abstract: PURPOSE:To heat-set only a desired part through the intermediary of a heating material by providing a high-frequency induction heating body in the intermediate part of a pipe material of a thermoplastic synthetic resin pipe and by heating only the desired part. CONSTITUTION:A pipe body 1 is formed of a thermoplastic synthetic resin material and a heating layer 2 is molded in a state wherein a material 21 having the same quality as the molding material of the pipe body l and a powder-grain substance 22 formed of a heating material are kneaded. The heating layer 2 is provided in the intermediate part of the pipe body 1 and moreover to be cylindrical at over the full length in the longitudinal direction of the pipe body. In addition, the heating layer 2 is molded integrally in the pipe 1. By applying high-frequency waves of high-frequency emitters E to parts N of a pipe 10 to be bent, the heating layer at these parts is heated to be softened. The pipe thus prepared is pressed in a mold M so that a crank type is formed, only the bent parts N of the pipe 10 are cooled down thereafter and thereby a crank- type pipe is obtained.

Title: Weighing method using quantitative scale
Inventor: NODA NOBORU
IPC: G01G13/12
Filed: 1979-08-08
Abstract: PURPOSE: To ensure a simple and accurate setting of weighing using a quantitative scale, by storing the head compensation value corresponding to the quantitative measurements at two points by the hopper or the like and then carrying out a proportional operation to the head compensation value between the two quantitative measurements.  
     CONSTITUTION: Head compensation values D 1  and D 2  corresponding to the accumulation caused by the open/close of the shutter corresponding to measurements T 1  and T 2  at two points by the hopper or the like are stored previously. Thus head compensaion value ΔD corresponding to set residual value ΔT between T 1  and T 2  based on set weighing value X obtained by equations I and II is decided by a proportional operation using equation III. Accordingly, if value ΔD is decided by the electronic computer or the like, the setting of weighing using a quantitative scale can be possible automatically in a simple and accurate on-line method. Based on this setting, a quantitative weighing is possible. Here K 1  and K 2  show the repetitive weighing frequencies; and T 1 ', T 2 ' and ΔT' are sensitive measurement values at the moment when the shutter is closed.
