Title: Carrier for holding body to be polished and manufacture thereof
Inventor: KINUMURA AKIRA
IPC: B24B37/27
Filed: 1990-03-14
Abstract: PURPOSE:To strengthen the stiffness of a carrier and to reduce the warp rate by using a laminated mica laminated sheet which a heat hardening resin is impregnated into and hardened in. CONSTITUTION:A prepreg is obtained by coating and drying a varnish consisting of a heat hardening resin on the laminated mica sheet 1a which a heat hardening resin is impregnated into and hardened in. This prepreg is punched in a circular shape. On the both faces of the prepreg a prepreg consisting of the heat hardening resin impregnated fiber layer in the diameter larger than those is laminated, heated and pressurized, one part of the heat hardening resin is extruded to the outer periphery of the prepreg and the heat hardening resin is hardened as well, and then the laminated mica sheet 1a, the heat hardening resin impregnated fiber layer and the heat hardening resin impregnated fiber layer of the outer periphery of the laminated mica sheet each other are bonded. At this bonded part a tooth 2 biting with the sun gear and international gear of a double face polishing machine is formed and yet plural insertion holes 3 of the body to be polished are formed on the discoid face including the laminated mica sheet 1a. The desired carrier for holding the body to be polished of a strong stiffness can thus be obtained.

Filed: 1989-03-17
Abstract: PURPOSE:To easily detect a vacuum leak by providing a means which stores a position on the outer peripheral surface of a vacuum container and leak data at the position and a means which changes the position. CONSTITUTION:The vacuum container 1 is evacuated by a vacuum pump 11 and a microcomputer 9 controls a helium gas supply device 17 to blow helium gas out of a nozzle 4 to the container 1.

Further, while the helium gas is blown out of the nozzle 4, the signal from a helium detection sensor 12 is inputted to a helium detector 13, whose signal is inputted and stored. The signal of the rotation quantity given to the motor 3 and the outer peripheral surface position of the container 1 that the nozzle 4 faces are also stored. Thus, the automatic scanning of the nozzle 4 is performed and leak data on the outer peripheral surface of the container 1 can be stored, so the vacuum leak is easily detected.

Title: Information terminal equipment
Inventor: HIRAHARA TADAHIRO
IPC: H04N7/173
Filed: 1986-03-24
Abstract: PURPOSE:To lighten the burden in terms of retrieving desired picture data by storing a piece of data specifying a picture frequency used in a memory means in a lump. CONSTITUTION:Previously the picture number specifying data frequently used and fine tuning data adjusting a data transmission stop time are stored in a RAM 10. When the operation shifts to a program execution mode, first a signal processing circuit 4 reads data stored in the RAM 10. If it is the picture number specifying data, the circuit 4 transmits a data transmission command (h) to a MODEM 3 and the picture number specifying data to an information center through telephone lines L1 and L2, thereby obtaining desired data. If data read out of the RAM 10 is the fine tuning data, the circuit 4 causes a time counter 11 to count the data. When the data comes to zero, the picture number specifying data on the next picture is read in and transmitted to the information center.

Filed: 1984-03-31
Abstract: PURPOSE:To enable switching at high speed by forming a region in which charge carrier life formed by irradiating a specific section in a low impurity density region by proton rays is shortened. CONSTITUTION:An N<+> cathode region 51 and P<+> gate regions 53 formed on the opposite surface of a P<+> anode 52 are obtained by selectively diffusing phosphorus or arsenic into the region 51 and boron into the regions 53. A region 56 in which charge carrier life shaped by projecting proton rays into an N<-> layer 54 is shortened if formed. The region 56 can be shaped at a desired position in the N<-> layer 54 by controlling the energy of proton rays, and the extent of the shortening of charge carrier life can be selected by the quantity of proton rays projected and an annealing process after projection. A high-speed switching device, loss thereof is low and which has high efficiency, is manufactured because the region in which charge carrier life is shortened can be localized only at a position effective for shortening current lowering time tf.

Title: Storage circuit
Inventor: KAWAKAMI AKIRA
IPC: G11C11/413
Filed: 1980-05-19
Abstract: PURPOSE:To avoid a multiplex selection of a memory cell, by latching the address information to maintain a level of ''1'' or ''0''. CONSTITUTION:The address input information is applied to a gate A of a MOSFET6, and the potential of a node 3 is decided by the inverter ratio between MOSFETs 5 and 6. In the same way, the potential of a node 4 is decided by the inverter ratio between MOSFETs 8 and 9. The potential of the node 4 is positively fed back to the gate of the MOSFET, Tr7; and the potential of the node 3 is positively fed back to the gate of the MOSFET9. If the node 3 is ''1'', the node 4 is ''0''. The potential of the node 4 drives a driver, and the memory selection information is delivered from output teminals OUTs 3 and 4 of the driver to drive a decoder. The memory selection information delivered to the OUTs 3 and 4 of the driver is not turned to the intermidiate potential owing to a positive feedback. Thus a multiplex selection is never caused for a memory cell.
