Title: Bus precharge circuit and bus system using the same
Inventor: KUDO TSUNEAKI
IPC: G06F3/00
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a bus system with which power consumption reduction and high-speed operations are enabled. SOLUTION: When an address signal/AO is '1', a control signal E0 gets equal with '1', a control signal E1 gets equal with '0' and the state of outputting data from a block 1-0 to a bus 2 is provided. Output data Q0 from a flip-flop 5-0 of the block 1-0 are inputted to a bus precharge circuit 3 before being outputted to the bus 2. When the output data Q0 are '1', the bus precharge circuit 3 does not precharge the bus 2 even when a clock CLK becomes '1'. When the output data Q0 are '0' and the clock CLK becomes '1', the bus precharge circuit 3 precharges the bus 2. In the case of reading data out of a block 1-1, precharge is performed at all times.

Title: Residual pressure mechanism for master cylinder
Inventor: SOMEYA NOBUTAKA
IPC: B65G19/02
Filed: 1978-07-10
Abstract: PURPOSE: To produce predetermined residual pressure in a brake system by providing a floating value body which retains a valve in open state at vacuum evacuating time and in closed state after charging.  
     CONSTITUTION: When brake liquid is not filled in a communicating chamber 11, a valve body 20 makes elastic contact with a seat surface 10a by a spring 13, and a floating valve body 22 is located at relatively lower position by its own weight. The upper flange 23 makes contact with the upper surface of the valve body 20. The communicating chamber 11 communicates through a valve hole 20a and a hole 24a with a liquid pressure supply hole 15 to thereby communicate air therethrough. When the chamber is evacuated in vacuum in this state, it can be rapidly and exactly evacuated with air. When a piston is returned after a wheel cylinder is operated, the valve body 22 is moved upwardly to return the liquid through the gap between the valve body 20 and a plug 10. When the brake system is lowered less than predetermined pressure, it is shut off by the spring 13.

IPC: G06F13/00
Filed: 1992-04-07
Abstract: PURPOSE:To reduce a time loss generated at the time of reissuing a program and to reduce the load of an operator and a computer device by storing history information specifying final processing data out of processing data stored in one or more processing files. CONSTITUTION:In the case of executing a processing program P1 built in a computer device 1 and transmitting data to a processing program P2 built in a computer device 2 through a communication line 3, the processing status of a processing file F1 is recorded in a history file F2. At the time of reissuing a program, the leading part, i.e., a processing continuing point, of unprocessed data stored in a file F1 can be determined by one I/O operation to/from the file F2 based on the processing status data recorded in the file F2. Since the number of I/O times to/from the file F1 to be executed for reexecution at the time of abnormal end of an on-line program can be reduced by adding the history file a queue time required up to the determination of a processing continuing point can be shortened.

IPC: G01H3/00
Filed: 1981-06-03
Abstract: PURPOSE:To measure tones stably with high accuracy and to perform the production of marker sounds and fault displaying of an electric power source surely by measuring the tones digitally. CONSTITUTION:After the sound signal produced by a tuning string converted by a microphone is amplified by an amplifier 2, the pulse wave signals synchronized with basic wave components are outputted from a synchronous oscillator 3.  The 1st counter 14 generates an output when it counts said pulse wave signals  by as much as the predetermined number, and the 2nd counter 32 counts reference clock pulses for measurement. The counting of the 2nd counter 32 is continued over the period from the count starting of the 1st counter 14 until the  generation of the output by a control part. The integrated value of the 2nd  counter 32 is displayed in a display part 35, and when a sounding switch 34 is  closed, the frequency divided output of the 2nd counter 32 is supplied to a sounding body driving part, by which the marker sound of a reference scale is obtained. When the source voltage drops below the reference value, a detection  circuit operates and a display device 35 flashes to display this.

Filed: 1996-03-14
Abstract: PURPOSE: To provide a refuse bag storage box whose structure can be folded by making columns stand at four corners to form a box structure, jointing opposing columns to each other so as to expand and contract, and moving one column to the other column, and which can be folded with one touch so that the box may perform no interference on other days than a refuse collecting day. CONSTITUTION: When using a storage box, movable columns 1, 1' are drawn out forward with the movable columns 1, 1' and stationary columns 2, 2' folded so that they may be in proximity to each other. Bracings between the movable columns 1, 1' and the stationary columns 2, 2' are then opened in an X form. At this time, a net-shaped or cloth element is tensed above a front plate 17. When throwing in a refuse bag, a rod 19c is lifted up from an L-shaped locking member 20 and placed onto a U-shaped hardware 21. The polyvinyl bag storing refuse is thrown in from an opening at the front top of the storage box. When refuse is not required to thrown in, or when storing, the rod 19c is fitted onto the locking member 20 to close the opening and prevent a crow, cat or the like from invading.

Title: Contact electrostatic charger

IPC: F16C13/00
Filed: 1992-03-06
Abstract: PURPOSE:To carry out appropriate electrification of a photosensitive drum by providing a conductive layer with a low resistance value to an electrifying member. CONSTITUTION:A roll part 20b of the electrifying roll 20 is a sponge roll and a conductive layer 20c is applied and formed on the outer peripheral, surface of the roller part 20b. Although the thickness of the conductive layer 20c is unneven because a part of the conductive layer 20c is entered into a cell (air bubble) 14 opened on the surface of the roll part 20b, no effect is imparted on the distribution of resistance of the electrifying roll 20 since its resistance value is low. On the other hand, because the outer peripheral surface of the conductive layer 20c is smooth, the thickness of the resistance layer 20c applied and formed over it is made even, and as a result, the distribution of resistance of the electrifying roll itself is also made even.

Filed: 1981-06-05
Abstract: PURPOSE:To remove the work strain of a core and to improve the work precision of a tape contacting surface, by leaving the circumference of the core gap of the tape contacting surface as a projecting part by grinding work. CONSTITUTION:The tape contacting surface 5 of a head 2 is ground by a grinding stone 10 having recessed parts 11.

Then, lapping work which uses fixed abrasive grains and free abrasive grains is carried out to remove the projecting parts 9, thus finishing the surace into a smooth tape contacting surface. The lapped areas are limited nearly to the projecting parts 9, so the work time is shortened and the work precision of the entire tape contacting surface 5 is improved.
