Title: Semiconductor memory
Inventor: NAKAOKA YUJI
IPC: G11C11/401
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory which can conduct readout after write burst without one clock of delay in the 2-bit prefetch system. SOLUTION: Although write to sense amplifiers 111, 112 is initiated with delay of one clock period, the data-in-buffer 118 and the write amplifiers 114, 116 are disabled by signals WO, WAE generated by a signal generator 121 and internal clock signals ICLK at this time. During this period write data is exchanged, and the signal WO and the write amplifier activating signal WAE are brought to a high level to write data into two consecutive addresses. Also at the time of readout operation, the time of generation of internal address from the CLK signal and the control method of column select line CSL are made the same as those at the time of write operation and only at the time of write operation only the write operation until the DIN 118 memory cells 110, 113 is delayed by one clock period of the external clock signal CLK to make the selection operation of the CSL be undelayed.

Title: Wideband amplifier wherein feedback is done to bias circuit by current mirror
Inventor: ANSONII DEII UONGU
IPC: H03F1/30
Filed: 1989-07-25
Abstract: PURPOSE: To obtain the broad band amplifier being an integrated circuit operated with high reliability by providing an internal capacitor for compensating a bias circuit to an input bias feedback circuit. CONSTITUTION: A current mirror including transistors(TRs) 32, 33 in a bias feedback circuit 22 detects an increased current of a TR 2 and decreases it to 1/20. Similarly a current mirror including TRs 41, 42 detects the current increase in the TR 2 to decrease it to 1/20. Thus, 1/40 of the sum of currents flowing to respective emitters of the TRs 1, 2 flows to a TR 45 to increase an impedance at a node 46 to be very high. Then a compensation capacitor 65 is connected from the node 46 to a negative power supply -VS. Thus, no external compensation capacitor is required and the broad band amplifier being an integrated circuit provided with an internal capacitor for bias circuit compensation is obtained.

Filed: 1992-06-29
Abstract: PURPOSE:To simplify a structure so as to facilitate a building process by integrally providing a protrusive shaped shadow grid part, which controls thermion emission shielded, in a thermion emitting surface of porous metal for constituting a cathode. CONSTITUTION:Porous tungsten of constituting a cathode 20 is machined into a predetermined shape, and a part except a protrusive shaped shadow grid part 20a is cut by a diesinking electric discharge machining method, to form an electron emitting part 20b. Next, the electron emitting part 20b is impregnated with an electron emitting substance mainly composed of barium oxide, to manufacture an impregnation type electron gun. Thus in work by the diesinking electric discharge machining method, a surface of the electron emitting part 20b, formed to be cut by a discharge between an electron emitting surface of the cathode 20 and an electrode, holds porosity, and a surface of the shadow grid part 20a of protrusive shape, left as not cut, is left as crushing a void, so that an electron can not be emitted. Accordingly, the shadow grid part 20a can be actuated as a shadow grid.

IPC: G06Q40/00
Filed: 1993-07-08
Abstract: PURPOSE:To detect the signing state of a user even after the end of signing is detected by means of a signing stage which is moved by the writing pressure and then to confirm the end of signing in an entire signable range covering up to the end of closing of a shutter. CONSTITUTION:When the signing action of a user is over and a signing end confirming signal is supplied, a signing stage is once fixed upward for a prescribed minute time and then unfixed upward. If the output of a signing stage detecting means shows a light state for a prescribed time under such conditions (i.e., when the signing stage is kept upward and no signing action is carried out), a signing end state is decided and a shutter is closed. If the output of the signing stage detecting means shows a dark state for a prescribed time (i.e., when the signing stage is kept downward and the signing action is started again), an unfinished state of the signing action is decided and the input of the signing end confirming signal is waited for. If the output of the signing stage detecting means shows a dark state during a closing action of the shutter after the end of the signing action, a singing unfinished state is decided and the shutter is opened. Then the input of the signing end confirming signal is waited for.

Title: Method and apparatus for polishing semiconductor wafer
Inventor: SHIBAYAMA TAKASANE
IPC: B24B37/00
Filed: 1992-07-21
Abstract: PURPOSE:To stabilize the wafer surface roughness and prevent the reduction of polishing speed by installing an electric dust collector midway in piping for polishing liquid and recycling the liquid while separating and removing aggregated colloidal silica. CONSTITUTION:Polishing liquid 8 containing colloidal silica is fed from a storage tank 7 to a polisher 4 by a feed pump 9. Very small silica particles produced during polishing of wafers 2 are, together with the polishing liquid 8, returned to the storage tank 7 through a polishing liquid return pipe 6. Colloidal silica aggregated during recycling of the polishing liquid 8 is separated and removed by an electric dust collector 10. The electric dust collector 10 comprising a cathode 13, collector 14 and anode 15 is installed midway in the piping on the downstream side of the pump. Hence, the particle size distribution of the polishing liquid 8 fed to the polisher 4 is controlled. This stabilizes the particle size distribution of colloidal silica and thus the wafer surface roughness.

IPC: B41K3/00
Filed: 1982-11-05
Abstract: PURPOSE:To make it possible to eliminate the possibility of any error of data even when it is made possible to change a unit price from the balance side, by a method wherein when a unit price is changed a mark-down mode is set; when no unit-price change is effected a rewrap mode is set, and each label is provided with an indication of either of the modes. CONSTITUTION:A unit price can be changed also from the balance side in either MARKDOWN or REWRAP mode through the operation of a mode changeover switch 39. The contents of the data processing at this time are stored in an MD memory (mark-down memory) or RW memory (rewrap memory). Moreover, when a unit price is changed in the unit-price changeable state, the MARKDOWN mode is set. On the other hand, when no unit-price change is effected in the state, the REWRAP mode is set. Thus, two modes are automatically changed over, and data on these modes are added to the respective memory devices, thereby preventing any error of data in checking of a total or the like. In addition, a printed label is provided with an indication of either of the modes.
