Incident light is reflected by the glass 13 for light shielding within a counter substrate layer when transparent electrodes are formed on the mosaic color filters and the filters are used as the counter electrode of a liquid crystal panel. Brightly displayed images are then obtd. without mixing of the adjacent colors with each other.

Title: Block editing control system
Inventor: ERIKAWA TOSHIFUMI
IPC: G06F17/21
Filed: 1987-10-15
Abstract: PURPOSE:To improve the operability of a block editing control system by switching automaticaly the block edition and the normal edition in a block editing mode. CONSTITUTION:An editing mode identifying means 1 identifies a block editing or normal editing mode at present and delivers the control to a normal editing means 4 with the normal editing mode and to a block editing necessity deciding means 2 with the block editing mode respectively. The means 2 checks the character strings at and after the editing start position and judges the necessity for the block editing according to the earlier emergence of a vertical ruled line component or a line feed function character. Based on the result of said decision, the control is delivered to a block editing means 3 or the means 4. Thus both means 3 and 4 perform the editing jobs in each editing system. Thus the automatic switch is possible between the block and normal editing jobs in a block editing mode. Then the mode switching actions are not required for each time and the operability is improved with a block editing control system.

Title: Semiconductor device and manufacture of the same
Inventor: KIMURA MASATOSHI
IPC: H01L27/105
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce wiring resistance and contact resistance by defining a memory cell portion as a non-silicide region and also defining a logical circuit region including a peripheral circuit region other than the memory cell or the peripheral region as a silicide region. SOLUTION: For example, in a transistor element formed in a logic circuit forming region (including a peripheral circuit region) which is a silicide region 2, a semiconductor device selectively forms silicide layers 8, 9 on the surface of a gate electrode 5 and a source/drain region 7. Thereby, a low resistance of gate electrode 5, namely word line and also low resistance of contact resistance of a contact 12 formed in the condition being connected to the source/ drain region 7 can be realized. Moreover, since a sidewall is not formed at the sidewall of the gate electrode 6 forming a transistor element of a non-silicide region 1 for controlling junction leakage by controlling the formation of the silicide, damages from etching given to the surface of a semiconductor substrate 3 can be reduced.

Title: Data transfer system
Inventor: OSHIMA TOSHIHARU
IPC: G06F13/42
Filed: 1985-11-20
Abstract: PURPOSE:To improve the data transfer efficiency to I/O controllers of different answer times by changing programably a transfer answer time signal. CONSTITUTION:A register 18 can give freely programmable changes of time changeover to a register 13 of a DMA controller 10 and the transfer answer times are set as desired to each controller 4 via a host computer. This set answer time is extracted in response to the transfer request signal DREQ produced from the controller 4. Then a transfer answer time signal DACK is given to the corresponding controller 4. Therefore it is not needed to secure the coincidence between the controller having the largest transfer answer time and the controller 4 having different answer times. This improves the data transfer efficiency.

Filed: 1993-10-19
Abstract: PURPOSE: To obtain a blind rivet setting tool of a low cost by providing this tool with a means for driving a motor to move a pulling head assembly in an advancing or parting direction, detecting the load of the motor changing between a minimum load and an intermediate load and stopping the operation. CONSTITUTION: The tool having mandrels for setting blind rivets detects the motor load for driving a pulling head body 38 between a position where the pulling head body is fully advanced and a position where the pulling head body is retracted. If the intermediate load is not detected within a prescribed time when the pulling head 38 moves in a rivet setting direction or if there is a decrease from the intermediate load to the minimum load after the detection of the intermediate load even when the intermediate load is detected, the operation of the motor is reversed. When the pulling head 38 is moved in an opposite direction, the pulling head 38 engages the stop position in the position where the pulling head is fully advanced. The motor is stopped when the intermediate load is detected.

Title: Liquid crystal panel for liquid crystal projector
Inventor: HATANAKA MASATO
IPC: G02F1/1335
Filed: 1991-09-13
Abstract: PURPOSE:To eliminate the unevenness of brightness of video or picture by driving a liquid crystal element by the video signal which is modulated by a control voltage changed synchronously with vertical and/or horizontal scanning periods. CONSTITUTION:When a vertical synchronizing signal is inputted to a vertical saw tooth wave voltage generator 20, this generator 20 generates a control voltage. This control voltage changes the linearly increased or reduced part to a proper curve in a vertical synchronizing parabolic waveform generator 24. It is inputted to a multiplier 22, and the video signal is modulated by the control voltage to output a driving voltage of the liquid crystal element. Then, the light transmittance is uniformized in the part where light is transmitted and the part of the liquid crystal element where light is not transmitted because the liquid crystal element is driven with the proper voltage. When a horizontal synchronizing signal is inputted, the light transmittance is uniformized in the same manner. Thus, videos or pictures are easily superposed one over the other, and the characteristic matching adjustment is easily performed. Then, the unevenness of brightness on the video or the picture projected on a screen is eliminated.

Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To reduce the need for terminating a prefetch operation and to improve a data transfer rate in DMA reading by once terminating data prefetch, when a termination condition is deemed to be realized and continuing it again and continuing data prefetch, when a prefetch request is issued to the boundary of pages at present. SOLUTION: When IOC 10 receives the last CMA reading transaction from an I/O bus 30, read data kept in a prefetch part control is transferred to the I/O bus 30. Perfetch reading on an address obtained by adding '1' to the address value of the last DMA reading transaction arrived from the I/O bus is issued to a system bus. Input/output controllers 60 to 63 receive read data transferred to the I/O bus 30, the last DMA read transaction is terminated. When a memory is not incorporated, IOC inform a prefetch control part 11 that data did not arrive.

Filed: 1988-10-19
Abstract: PURPOSE:To unify the input of a command by converting commands by unified specifications into operating commands by a command converter and issuing the other commands to sub and main systems without conversion. CONSTITUTION:Upon the receipt of a command based on the unified specification stored in advance from an input device 1, a command converter 2 converts the command into a command used for sub systems 4, 5 and a main system 3 and supplies the result to the systems 4, 5 and the system 3. Upon the receipt of other commands than the unified specifications, the converter does not convert the commands but gives them to the systems 3, 4, 5. On the other hand, a display area selection unit 9 receives the kind of information and the display information from the systems 3, 4, 5, selects the display area based on the unified specification stored in advance by using the type of the information and displays the display information received from the systems 3, 4, 5 on the area. Thus, the convenience in use is remarkably improved.
