Title: Arc welding method for high damping steel sheets
Inventor: HORII YUKIHIKO
IPC: B23K9/23
Filed: 1989-07-20
Abstract: PURPOSE:To reduce the high damping performance deterioration by heating the faces to be welded by a gas burner to burn up resin, then, inserting a spacer into a part where the resin existed or tack-welding plural steel sheets to secure the space and performing welding. CONSTITUTION:The resin to the extent that it is dissolved and evaporated by arc welding heat is burnt up and then, welding is performed. The spacer 3 is inserted continuously and intermittently into the position where the resin existed for shrinkage of a weld zone or tack-welding 4 is performed continuously or intermittently and the space where a resin layer 2 existed is secured and welding is performed. Metal or nonmetal, for instance, a ceramic thin plate which resists shrinkage at the time of welding and does not produce gas can be used as the spacer. Further, in order to prevent the flow of resin to the weld zone, one layer welding is desirable. By this method, welding can be easily applied to the manufacture of a structure utilizing the high damping steel sheets and the large-sized structure can be manufactured.

Title: Synchronization switching method of inverter for driving synchronous motor
Inventor: KATO TETSUYA
IPC: H02P1/50
Filed: 1993-07-29
Abstract: PURPOSE:To provide a system for switching a PM motor automatically and synchronously from one of a plurality of inverters to another inverter in which the synchronous switching can be effected quickly and positively in safety even upon variation of the r.p.m. of motor. CONSTITUTION:The periods of output signals (f) from inverters 1, 2 are matched under a state where a PM motor 4 is driven by an inverter 1. The inverter 2 is then waited temporarily and a synchronism matching signal is delivered in order to switch the connection of the PM motor 4 to the inverter 2 side. When a voltage is induced in the PM motor 4 and the period and phase thereof match those of an output signal from the inverter 1, operation of the inverter 2 is resumed while matching the period and phase with those of the voltage induced in the motor.

Title: Semiconductor storage device
Inventor: TARUISHI TOSHINORI
IPC: G11C11/409
Filed: 1994-07-18
Abstract: PURPOSE:To prevent contention of read out data by providing a precharging means provided between respective common data lines and prescribed potential supplying points and made to be selectively ON at the time of a non-selection and at the time of the mask of a block writing mode. CONSTITUTION:When an internal control signal RD is made to be an L-level, since precharging MOSFETs P2 to P4 of a write amplifier WAO are turned to ON-states, they are both precharged to H-levels like the power source voltage of a circuit. However, when a synchronous DRAM is made to be a selection state with a write mode and an internal control signal WT is made to be d H-level, P2 to P4 are turned to OFF-states. Instead of them, output MOSFETs N7, N8 are selectively turned to ON-states according to the logical levels corresponding to internal input data DIO. As a result. noniversion or inversion signals such as inter-mat complementry common data IC00 and so forth are selectively made to be L-levels like the grounded potential of the circuit and then the writings of logics Os or Is with respect to selected memory cells are selectively performed.

Title: Information processor
Inventor: KANAZAWA TAKASHI
IPC: G06F11/00
Filed: 1987-07-29
Abstract: PURPOSE:To omit the confirmation of the communication received from the firmware that is performed by a system controller and to shorten the information processing time, by providing a means which gives a communication request to a system controller from the firmware of an arithmetic processor. CONSTITUTION:When a retry instruction ends normally, a firmware 170 stores the end state in a holding means 115 and a suppressing means 120 inhibits the updating of an arithmetic processor 100. Then a system controller 200 reads the information out of the means 115 by a request given from a communication request means 145. When the normal end of the retry instruction is confirmed, the controller 200 gives an instruction to a communication releasing means 150 to clear the holding information and to release the means 120. Then the controller 200 releases the request of the means 145 and sets the firmware 170 under a start waiting state. In such a constitution, a communication means is used in accordance with the communication type when the communication is carried out to the controller 200 from the firmware 170. Thus the controller 200 is not required to decide the communication type and the information processing time is shortened.

Filed: 1987-07-30
Abstract: PURPOSE:To lower temperature dependency, by setting the clamp level of a clamping circuit based on a dark current generated at another charge transfer device which performs a charge transfer operation based on a driving signal, for a constant period. CONSTITUTION:Driving signals phi1 and phi2 to be supplied to a delay element(CCD delay element)1 consisting of the charge transfer device are supplied to a dummy CCD9 via a frequency divider 12, respectively. The frequency division ratio K of the frequency divider 12 is set at K=M/N assuming the number of bits of the CCD delay element 1 as N, and that of the dummy CCD9 as M. Therefore, the dummy CCD9 performs the charge transfer operation of one bit at every charge transfer of K bits by the CCD delay element 1 based on the driving signals phi1 and phi2. And the generating quantities of the dark currents of the delay element 1 and another charge transfer device for a temperature can be set so as to be in constant proportional relation. In such a way, it is possible to obtain a clamp level with quite low temperature dependency.

Title: Printing paper feeding mechanism
Inventor: YASUHARA MASATOSHI
IPC: B41J13/30
Filed: 1987-07-29
Abstract: PURPOSE:To prevent a printing paper from entering a device with a skew, by inclinking rotary shafts for a driving roller and a driven roller, which are rotated while clamping the printing paper therebetween from the upper and lower sides through a slot, relative to a paper feeding direction, and setting the feeding direction toward a stepped part. CONSTITUTION:A driving roller 6 and a driven roller 7 in a roller part 3 feeds out a printing paper on a paper guide 2 by being rotated while clamping the paper therebetween from the upper and lower sides through a slot 10. Rotary shafts for the rollers 6, 7 are inclined at a predetermined angle to a feeding direction A for the paper, and rotating surfaces of the rollers are directed toward a stepped part 4 of the paper guide 2. When the paper is fed in the feeding direction A, a sensor provided on the upstream side of the roller part detects the paper, and the roller part 3 is started rotating. Since the roller part 3 is fitted in the state of being inclined to the left, even when the paper is inserted with a skew to the left or right, the paper is fed forward while being turned leftward (counterclockwise) by the roller part 3. The printing paper has the left head edge and the right head edge thereof brought into contact with the stepped part 4 of the paper guide 2 in that order, whereby the paper is directed in the paper feeding direction A. As a result, the paper is led into a device with the feeding direction corrected.
