Title: Exchanging time discriminating device for parts of vehicle
Inventor: ISHII YUKIHISA
IPC: G01M99/00
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To maintain the performance of a vehicle safety by integrating the using time and the using frequencies of the parts of the vehicle and discriminating an exchanging time when the integrated value exceeds a prescribed value so as to positively urging a user to exchange the parts. SOLUTION: An electronic control unit ECU is composed of a microcomputer, e.g. as an integration means and a discriminating means to store the using time of a power pump 8 and the using frequencies of first and second relays 9 and 10 in a memory. Then when the power pump 5 and the relays 9 and 10 are used again, ECU integrates the using time and frequencies with those of previously stored in the memory to store in the memory again. Then ECU compares them respectively with the regulated values showing the exchanging time stored in the memory, namely a durable using time and using frequencies, and when the integrated value reaches the regulated value, ECU displays that an exchanging time of the pump 5 and the relays 9 and 10 are reached. Thereby the exchanging time of the parts for the vehicle which can not be seen directly is informed to the user.

Title: Semiconductor circuit for counter and said counter
Inventor: AKIYAMA TOORU
IPC: H03K23/40
Filed: 1982-03-12
Abstract: PURPOSE:To decrease the number of component elements and to facilitate the conversion into an LSI, by connecting terminals -Q and D of a D-FF via a switch circuit and then turning on the switch circuit only when the inverting conditions are satisfied. CONSTITUTION:The state of a certain bit is inverted, i.e., a D-FF is changed to a set state from a reset state only in case the states of lower bits are all set at ''1''. In other words, Q3 changes to ''1'' from ''0'' only in the case of Q1=Q2= 1. Based on this principle, a switch circuit is connected between a terminal Q of the D-FF and an input terminal. Then the switch circuit is turned on only when the above-mentioned inverting conditions are satisfied. Thus the binary storage state of the D-FF is inverted.

Title: Serial access memory
Inventor: MAEDA YASUNORI
IPC: G11C11/413
Filed: 1991-03-06
Abstract: PURPOSE:To enable a pipeline operation without dividing a memory array and to realize a high speed writing operation by changing over a selection of word lines during the time the write-in is made to a latch circuit. CONSTITUTION:When a W1 of the word lines 6 is in the selection level and W2-W4 of the lines 6 are in the nonselection level, the memory cells 11-18 connected to the W1 are successively accessed by an address increment to perform the writing operation. When the W1 is changed over to the nonselection level and the W2 is changed over to the selection level, the write-in information to a memory cell 21 is once fetched to the latch circuit 5 by an S1 of column line selecting signal lines 7 since the writing into the cell 21 is unable during this period. Next, a memory cell 22 is accessed, but the selection of W2 is defined at this time, so the write-in is executed to the cells 21, 22 by an S2 of lines 7.

Title: Device for adsorbing parts
Inventor: IDO TAKAO
IPC: B23Q7/04
Filed: 1983-03-10
Abstract: PURPOSE:To enable dealing with large and small parts, make a part adsorbing device compact and reduce the shock on each part, by concentrically arranging a plurality of pipes having adsorbing nozzles at the ends and by sliding the pipes and protruding them with springs to selectively use the nozzles. CONSTITUTION:When a roller 8 is pushed down by a tappet 9, a pipe 4 is moved down so that a nozzle 19 is brought into contact with a part 37 just under the pipe. After that, a spring 21 absorbs the inertial motion of the pipe 4 to prevent excessive pressure from acting to the part 37. When air is sucked through a hose 18, the part 37 is sucked on the nozzle 19. The tappet 9 is then elevated to move up the part 37 sucked on the nozzle 19. After an index table 1 is moved so that part adsorbing device 2 reaches a next work station, the pipe 4 is moved down again and the part 37 is released from the nozzle 19. A pick-and-place operation is thus completed. Since each tappet is pushed down depending on the size of the part, a variety of elements can be adsorbed.

IPC: G01R31/327
Filed: 1994-03-10
Abstract: PURPOSE:To provide a synthetic breaking test circuit by which a hardly attenuated zero miss current can be obtained. CONSTITUTION:When AC voltages of generators 5 and 10 of electric current source circuits 1 and 2 reach a zero point, a first closing switch 6 is closed. At this time, an electric current 11 containing DC equivalence close to 100% flows to the secondary side of a first transformer 8, and this also flows to a specimen HGSG4. When generating voltages of the first generator 5 and the second generator 10 come to the next zero point after the first closing switch 6 is closed, a second closing switch 11 is closed. When the second closing switch 11 is closed, an electric current (i2) containing DC equivalence close to 100% similarly flows from the second electric current source circuit 2. From this time, a zero miss electric current (i0) by synthsizing an electric current (i1) and the electric current (i2) flows to a specimen switch 4. A second auxiliary circuit breaker 14 is opened in time such as becoming arc time not less than prescribed 80ms, and a zero point is created in the zero miss electric current (i0), and in succession, a first auxiliary circuit breaker 9 is opened, and is simultaneously broken at the same electric current zero point with the specimen switch 4.

Title: Absorption structure of eccentric load to ram
Inventor: TAGUCHI MITSUO
IPC: B30B15/06
Filed: 1981-03-23
Abstract: PURPOSE:To obtain a press structure which is capable of absorbing an eccentric load  which is a reaction to a ram when working by press, by interposing a pair of opposed  buffer members having a spherical surface, between the ram and a punch holder. CONSTITUTION:In case when reaction force of F>(f) has operated against a shank axis  (a)-(a), a shank 3 is turned in the direction as indicated with an arrow centering around  the supporting point of a contact point B of a die 9 of a punch 6a and the axis (a)-(a) side. Accordingly, a projecting spherical surface 3a of the shank 3 goes down microscopically against a lower hollowed spherical surface 2b of a buffer member 2. As the  spherical surface 3a goes down microscopically, the member 2 goes down microscopically, as well, and is inclined to turn by being drawn along with turning of the spherical  surface 3a. In this case, since the diameter of a spherical surface 2a is smaller than the  diameter of the spherical surface 2b, a microscopic space is generated between a projecting spherical surface 1a of the tip of a ram and the spherical surface 2a, and the  member 2 is turned microscopically. Subsequently, the spherical surface 1a and the  spherical surface 2a, and the spherical surface 2b and the spherical surface 3a are  returned to the normal contact state by a fall of the ram 1 and also a controlling  action of repulsion compressive force of a return spring 7b.
