Patent JP-H1030449-A (JP)
Title: Compressor of refrigerating cycle for vehicle
Inventor: SAKAI TAKESHI
IPC: F02D29/04
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To obviate an unpleasant feeling in time of clutch engagement as preventing any possible rise in the manufacturing cost of a compressor. SOLUTION: A hydraulic pump part 1 driving a power steering system presses both clutch plates 9 and 10 by dint of hydraulic pressure to be generated, whereby both these clutch plates 9 and 10 are connected to each other. With this constitution, a variation in torque at the time of engagement between both these clutch plates 9 and 10 becomes moderated, and thus any unpleasant feeling in time of the clutch engagement is preventable, while since there is no need to install any exclusive hydraulic pump for engagement of these clutch plates 9 and 10, a rise in the manufacturing cost of a compressor is thus preventable.  In addition, when the detected value of a hydraulic sensor 18 has exceeded the specified value, it is so judged that a steering wheel angle has exceeded the specified value, therefore a solenoid valve 17 is closed, so that working pressure - the power steering system requires - is secured.

Title: Method for casting hollow as-cast product into metallic mold
Inventor: MATSUO NOBUKI
IPC: B22C9/10
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To weaken the combination of a pin for a hole as-cast and a hollow as-cast product with coating material and to easily pull out the pin for the hole as-cast by inserting the pin for the hole as-cast coating the coating material on the surface into a metallic mold, filling up molten metal in the metallic mold and pulling out the pin for the hole as-cast. SOLUTION: The coating material 21 is sprayed and coated on the surface of the pin 12 for a hole as-cast. The coating material 21 is the one pulverizing a borosilicate glass into powder and dissolving this powder with solvent. The pin 12 for the hole as-cast is inserted into a cavity 16 from an opening hole 17. Successively, the molten metal 22 in a ladle L is poured from a receiving hole 13 and filled up in the cavity 16. After pouring the molten metal, the temp. of molten metal 22 is gradually lowered and the surface layer of the molten metal 22 is changed into shell-state solidified layer. The coating material 21 on the surface of the pin 12 for the hole as-cast is molten-state. Then, the pin 12 for the hole as-cast is pulled out from the hollow as-cast product 23.  In the hollow as-cast product 23, a hollow hole 23a is formed and a part of the coating material 21 is remained on the hollow hole 23a. The coating material 21 serves as a lubricator to easily pull out the pin 12.

Title: Control method for printing
Inventor: INAGAKI MASAHISA
IPC: B41J11/20
Filed: 1980-12-29
Abstract: PURPOSE: To enable steady feeding of a medium without hooking of a crease on a printing means, by a method wherein, in an impact printer, when a crease of a printing medium passes through a gap between a platen and a printing means, the gap is widened more than that at a printing time.  
     CONSTITUTION: When a printing for one page on a medium 15 is complete and a crease 15b passe through a gap W between a platen 2 and a dot pin 11, the crease is detected by a signal from a form control buffer, a motor is run immediately to turn the platen 2 through a pulley 5, a belt 6, and a pulley 2b by 180° centering around a support shaft 2a. The support shaft 2a is positioned eccentrically aginst the center axis of the platen 2, and thereby the platen, which is in a condition to protrude toward a side of a printing head 7, moves backward in a direction of an arrow mark C to widen the gap W to W2 from W1. After the crease 15b passes through, a motor 3 is run again, and the platen 2 turns further by 180° to restore it to a condition at a printing time.

Title: Image forming device
Inventor: ITO SHINICHI
IPC: G03G15/16
Filed: 1992-07-15
Abstract: PURPOSE:To prevent irregularities in an image such as distortion or blurring from occurring by forming a toner image coincident with an electrostatic latent image formed on an electrostatic latent image carrier on a body to be devel oped. CONSTITUTION:A developing means is set to apply frictional force in a reverse direction to the moving direction of the body to be developed 102 to the body 102, and a tension means is disposed on the upstream side of the electrostatic latent image carrier 101 and on the downstream side of a transfer means in the moving direction of the body 102. The body 102 is stretched over the carrier 101, the transfer means and the tension means, and tension is added to the body 102 by the tension means. The frictional force applied to the body 102 by the developing means makes the moving speed of the body 102 lower than the circumferential speed of the carrier 101, but the tension means is not disposed on the downstream side of the developing means and the body 102 is pinched by pinching force by the transfer means, so that slide is not caused between the carrier 101 and the body 102.

Title: Memory device
Inventor: HAMADA YOICHI
IPC: G06F11/10
Filed: 1985-08-27
Abstract: PURPOSE:To obtain a memory device having high reliability by providing a data selector to select one bit out of the multi-bit width of a DRAM and performing the transfer of data from and to an ECC for each data word consisting of said selected bit. CONSTITUTION:In an access mode, address signals are applied to all DRAMs 4C0-4D7 and selection designating signals are supplied equally to all data selectors 2C0-2D7 and 3C0-3D7 from a driver 5. Thus a single piece of word data on the same output terminal is selected. This selected data word of a bit is used as a single unit for transfer of data between an ECC 1 and the DRAMs 4C0-4D7 respectively. In a write mode with correction of errors, all selectors 2C0-2D7 are enabled for the signal of a driver 6. Thus the data words are written on the memories 4D0-4D7 via the selectors 2D0-2D7 and the redundant words are written on memories 4C0-4C5 via selectors 2C0-2C5 respectively. In a read mode, all selectors 3C0-3D7 are enabled by a driver 7. Then the data words and redundant data words are read out via selectors 3D0-3D7 and 3C0-3C5 respectively. In such constitution, it is possible to obtain a memory device that is free from burst error with high reliability.

Title: Pressure flow controller for variable delivery pump
Inventor: TAKEUCHI TAKAHIKO
IPC: F04B49/06
Filed: 1987-07-28
Abstract: PURPOSE:To perform pressure control in an optimum manner by calculating a product of load capacity and fluid compressiblity of a pump from a rising speed of discharge pressure at the time of load stoppage and a flow rate, and controlling a feedback gain for the pressure control. CONSTITUTION:A multiplier circuit 12 is installed the input of a servoamlifier 3 for pressure control, and a pressure deviation signal out of an adding point 9 and a signal out of a gain arithmetic and control unit 10 are inputted therein. This gain arithmetic and control unit 10 calculates a product of load capacity and fluid compressibility of a pump from a rising speed of discharge pressure, when a cylinder as control load is stopped, and a flow rate, and it controls a feedback gain for the pressure control on the basis of this value. Consequently, in case of a fluid pressure utilizer in an extensive range different in capacity at the load side, such a requirement that the feedback gain of a pressure control loop to variable delivery pump is regulated at each device falls into disuse.

Abstract: PURPOSE:To increase the preservation performance of an active material without deteriorating the productivity by cutting an expanded grid so that crosspiece parts of the grid are located at both sides of the grid, and making the horizontal length of the nodal part of the mesh larger than that of the crosspiece part of the mesh. CONSTITUTION:An expanded grid 1' is cut in such a manner that crosspiece parts (a) of meshes of the grid 1' are located at both sides of the grid 1'. This is enabled by continuously punching small holes during the expansion work, at intervals equaling a width W of the grid 1', on a part of a lead alloy strip which is not expanded. Besides, the grid 1' is positioned by means of the above small holes during the formation of a lag, and is positioned by means of the lug during the cutting of the grid 1'. Here, the expanded grid 1' is worked so that a horizontal length (b) of the nodal part of its mesh is larger than a horizontal length (a) of the crosspiece part of the mesh.
