Title: Clock tree layout device
Inventor: UEMURA MARIKO
IPC: G06F17/50
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To decrease skews of clocks of different phases while maintaining a delay by generating and arranging dummy blocks in exactly the same number and arrangement positions as the blocks which are connected to the clocks. SOLUTION: Cells are arranged (S1), and (n-1) pieces of dummy blocks are generated and arranged at a place near the FFs(flip-flops) to which the clocks (i) are connected (S2). Then, connecting relations are established between the dummy blocks and the clocks of different phases (S3). The clocks (i) are clustered (S5) and then clustered again in consideration of arrangement of FFs (S6). The buffers are generated and arranged at the positions where the load balance is secured for every cluster (S7). If the output destinations of buffers are all dummy blocks, these blocks and their connecting relations are deleted, and the arranged buffers are replaced with the dummy buffers (S8). This processing is repeated until i>=n is satisfied and the equivalent delay wiring is performed for a clock tree (S11).

Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent transmission from becoming impossible by means of rapid voltage lowering by displaying presence or absence of dry cell usage, based on the output of a dry cell detecting means when the dry cell is used. SOLUTION: When a power source key is depressed in a state where a dry cell pack 2 or a secondary battery pack is mounted on a telephone set body 1 so as to permit the state to be the on-state, a control circuit 10 inspects whether or not the dry cell pack 2 is inserted by the dry cell detecting means 7. In the dry cell pack 2, the residual amount of a cell is not displayed in a secondary battery capacitance display/dry cell display area but the usage of the dry cell is displayed. When a call is started by call-incoming or call- originating, counting by a timer is started and the residual time of the call is displayed in a call residual time display area. When the call continues over a prescribed time, the warning buzzer of forcible call-ending is issued. Then, at the prescribed time, the call is made to end forcibly.

Title: Needle hardening preventing and cleaning device and application thereof
Inventor: OGAWA KATSUYA
IPC: B05C11/00
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent a residual viscous resin remaining in a dispenser needle for applying the viscous resin from becoming cured and facilitate the cleaning of a moisture preventive agent sticking to the tip of the needle without giving a load upon the needle by designing a structure for enabling the tip of the needle to be hermetically sealed against an atmosphere by soaking it into a solution with floating foam pieces. SOLUTION: A dispenser needle 1 for applying a viscous resin is inserted into a through hole 2a in a drop lid 2 and is pushed down. Consequently, the tip of the needle 1 is soaked into a solvent 4 and hermetically sealed against an atmosphere, so that a residual moisture preventive agent remaining in the needle 1 is prevented from becoming cured. In addition, a cubic sponge 5 afloat in the solvent 4 is pressed against the needle 1 and in turn, the moisture preventive agent sticking to the tip of the needle 1 is removed. Then the needle 1 is pulled upward and a lid 2 is pushed up by the repulsive force of a spring 6, resulting in the irregular movement of the cubic sponge 5 by a reaction to the repulsive force of the spring 6.  Thus the residual moisture preventive agent removed from the tip of the needle 1 is prevented from being concentrated to a single spot and is also prevented from sticking to the needle 1 again.

IPC: G03F1/64
Filed: 1991-11-27
Abstract: PURPOSE:To provide a method for sticking a pellicle supporting frame which is stable, has no secular change and is simple for a pressure detection. CONSTITUTION:As the adhesive material 11 is used indium, lead or those alloys which are inorganic metals that do not change the quality, are flexible and have plasticity and more malleability. Thus degradation of the adhesive strength of the adhesive material 11 due to the secular change and generation of a particle due to the decomposition are prevented. Also the metals are used for detection of the adhesive pressure as the adhesive material 11. By finding a magnitude of the pressure from quantity of deformation of the adhesive material 11 using of the plasticity, a simple and cheap method for detection of the adhesive pressure is realized.

Filed: 1986-12-27
Abstract: PURPOSE:To decrease under run or picture error due to picture data transfer delay by sending a reply signal to an opposite terminal type identification signal to a reception buffer after a prescribed quantity of picture data is received in a reception buffer in the MODEM sequence in succession to the call. CONSTITUTION:The transmission of a DSC (digital instruction signal) being a reply signal of an opposite identification signal to a DIS (digital identification signal) is awaited till prescribed quantity of picture information is received in the MODEM sequence after the call in the facsimile mode. It has been difficult in a conventional controller to send a data from a host to a communication function within 6sec after a CFR (reception preparation confirmation) or an MCF (message confirmation), but it is made possible. Moreover, it is possible to send a correct picture by providing a buffer data of a prescribed capacity or over to a communication function to be correspondent to the change in the transmission speed of the data to the line depending on the fines of the picture.

IPC: A63F7/02
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To relieve monotony in play and improve the pleasure of play by involving players in deciding whether they hit a jackpot or not. SOLUTION: If S162 is acceptable or the CUP detects any start of scrolling of special pictures, S164 actuates a first pilot LED to indicate that a special jackpot random number may be selected. If S166 is true or upon detection of a depression of a selection switch for special jackpot random numbers, S168 selects one from among the special jackpot random numbers of a table of special picture random numbers and S170 stores it before the first pilot LED is inactivated in S172. Players are thus permitted to decide, by their switching, the timing whereat one special jackpot random number is selected, not leaving it at the CPU's disposal, so that they can be consciously involved in play.

CONSTITUTION:When mouse clicking is performed after fitting a mouse cursor in the pick area 1a of an upper window 1 first in a multiwindow display system, the upper left corner of the window 1 is captured in paper shape. Next, when the mouse cursor is moved in a direction of arrow at a state where the window is captured, a captured point at the upper left corner is moved with the mouse cursor, and the window 1 is folded as if paper is turned over. Then, a part equivalent to a lower window 2 is displayed on the turned over part of the upper window 1. Thereby, it is possible to observe the lower window without moving the overlapped window to another part, which improves the working efficiency.

Title: Method for driving liquid crystal shutter
Inventor: FUJITA MASANORI
IPC: G02F1/133
Filed: 1987-12-11
Abstract: PURPOSE:To prevent blackening of transparent electrodes, discoloration of dichromatic dyes, deterioration of a liquid crystal, etc., even after long-term driving by adopting the AC pulses which are equal in both the waveform and number of the pulses of different polarities for the pulses to be impressed to shutter elements. CONSTITUTION:The ferroelectric liquid crystal 3 is sealed into the spacing between glasses 1 and 2 and the stable orientation state of the liquid crystal is set in a dark state by polarizing plates 4, 5 disposed on the outside of two sheets of the glasses 1 and 2. The DC pulses to put the ferroelectric liquid crystal 3 into a bright state are impressed to the shutter elements which are ought to write the bright state. The shutter elements are thereafter returned to the dark state by impressing the DC pulses of the polarities reverse with the DC pulses and a voltage 0 is impressed to the shutter elements which are ought to write the dark state. The AC pulses which are equal in the waveform and number of the pulses of respectively the different polarities are thus adopted to the pulses to be impressed to the shutter elements. The blackening of the transparent electrodes, the discoloration of the dichromatic dyes, deterioration of the liquid crystal, etc., are thereby prevented even after long-term driving. The contrast is thus increased and the performance as the shutter is improved.
