Title: Ink cartridge for ink jet printer
Inventor: IIDA YUJI
IPC: B41J2/175
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent the stagnation of air bubbles in the region connected to an ink supply port and to certainly supply the ink in an ink chamber to a recording head under stable pressure without leaving the same. SOLUTION: A container 1 having an ink chamber 3 provided to the upper part thereof and an ink supply port 2 provided to the bottom surface thereof, the membrane valve seat 4 composed of the elastic membrane arranged so as to divide the ink chamber 3 and the ink supply port 2 and having a through-hole 4a provided to the center part thereof and the valve disc provided so that the membrane valve seat 4 responds to the pressure difference between the ink chamber 3 and the ink supply port 2 are provided and the membrane valve seat is provided in an inclined state so that the region in the vicinity of the upper end 5a of the communication passage 5 extending from the ink supply port 2 of the peripheral edge of the membrane valve seat becomes highest. The membrane valve seat 4 receives difference pressure by its wide area to open the passage from the ink chamber 3 to the ink supply port 2 corresponding to the slight consumption of ink to supply ink to a recording head without allowing excessive negative pressure to act on the recording head and the pressure rise of the ink supply port 2 is absorbed in the ink chamber 3 by the deformation of the membrane valve seat 4. Further, air bubbles of the region B on the side of the ink supply gather to the vicinity of the upper end 5a of the communication passage 5 and are excluded by the flow of ink caused by the suction operation of the ink from the recording head.

Title: Solid surface measuring gauge
Inventor: TAKADA KEIJI
IPC: G01B15/00
Filed: 1986-06-04
Abstract: PURPOSE:To obtain more information from a surface of a specimen, by comparing the secondary electronic image, etc. obtained by scanning on a stylus over the surface of the specimen with a topography. CONSTITUTION:A stage 13 is displaced, a specimen 14 is made to approach a stylus 3 and an electric current of approximately 1mA is applied 9 to between them. This distance is made more reduced with the stage 13 and a 2-axis piezo-electric element 8 and the applied voltage is made to drop in such a way the current 1 stays constant. Electrons in the neighborhood of a tungsten Ef of a needle pass through a potential tunnel in the vacuum, pass through the vacuum and are irradiated onto the specimen 14. And, the secondary electron beam 2 dischanged from the primary electron beam 1 is detected by the secondary electron detectors 4, 5. An intensity signal of the elec tron beam 2 is introduced into a displaying apparatus 12 for display as luminance, etc. on a CRT. On the other hand, the stylus 3 scans over the specimen 14, and the stylus 13 is adjusted so as to keep the current 1 constant. Thus, when a X-Y scanning signal is made to synchronize with a X-Y scanning of the CRT, high resolution secon dary electron images of 20Angstrom  and less can be obtained. Further, a signal equivalent to an applied voltage to the element 8 is introduced into a displaying apparatus 11 and, a topography on a surface of the specimen is obtained as a luminance on the CRT.

Title: Pneumatic tire
Inventor: KUKIMOTO TAKASHI
IPC: B60C11/12
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To effectively inhibit heel and tow wear in each block; and to inhibit cracks and partial desorption. SOLUTION: In each block 8 of a pneumatic tire 1, a kicking part K has earlier wear at linear driving rather than a tread part F. Where, to provide each block 8 with uniform wear contrary to the above fact at turning driving, earlier wear is to provide to the tread part F rather than the kicking part K in each block 8. To achieve this purpose, the width of the tread part F in each block 8 is widened compared with that of the kicking part K to increase the horizontal force burden of the tread part F at turning driving, exerting earlier wear.

Title: Communication control equipment
Inventor: MIYAZAKI KENJI
IPC: H04L7/04
Filed: 1987-05-27
Abstract: PURPOSE:To improve the communication efficiency of serial communication equipment, by operating a shift register by using clock signals which are used for operating a cyclic redundancy check (CRC) calculator. CONSTITUTION:A CRC calculator 5 is installed to serial communication equipment 11 and, at the same time, the CRC calculator 5 is operated by means of the system clock 9 of a receiving-side microprocessor system 10. Therefore, since it becomes unnecessary to shift received CRC codes to the CRC calculator 5 by means of receiving clocks supplied for a MODEM, interruption of CRC calculation caused by discontinuation of receiving clocks can be prevented. In addition, insertion of dummy data after CRC codes on the transmitting side and CRC calculation with software by the microprocessor 10 on the receiving side become unnecessary. Therefore, the communication efficiency of the serial communication equipment 11 is improved.

Title: Forcibly releasing method from electrostatic chuck
Inventor: TANAKA YOSHITAKA
IPC: H01J37/317
Filed: 1993-05-31
Abstract: PURPOSE:To enable a wafer to be released from a mount surface without damage even if the wafer is still large in adhesion to the mount surface by a method wherein a specific pushing member is made to bear against the wafer sooner than the other pushing members. CONSTITUTION:A power supply is turned OFF to dismount a wafer 1 from an electrostatic chuck 2 after the wafer 1 is processed. Then, a moving mechanism is actuated, and all pushing members 3 are made to start ascending. At this point, while the pushing members 3 are on standby, a distance between the specific pushing member 3 and the wafer 1 is set shorter than those between the other pushing members 3 and the wafer 1. Therefore, the specific pushing member 3 bears against the wafer 1 first, so that only a part of the periphery of the wafer which the specific pushing member 3 bears against is pushed up. After a prescribed time elapses, the other pushing members 3 bear against the wafer 1. At this point, a part and the other parts of the periphery of the wafer 1 are successively separated off, and the wafer 1 is lessened in contact area with a mount surface 2a.
