Title: Tape carrier package and its manufacture
Inventor: FUJIMORI RYOICHI
IPC: H01L21/56
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To lessen the leaking and spreading of molding sealing material over to the surface of a tape carrier package(TCP) on the opposite side to its surface to its surface to which the molding sealing material is applied, on the occasion of its application. SOLUTION: By providing protruding substances (dams 5) on the backside of a carrier tape, leaking and spreading of molding sealing material is stopped. On the backside to a surface to which a molding sealing material 7 is to be applied, dam material 4 composed of constituents such as polyimide, epoxy, etc., is printed through a stencil mask 3 made up of a stainless or screen mask. This dam material 4 is moved on the stencil mask 3 by a squeegee 6 made out of silicone rubber and so on. The stencil mask 3 had holes bored at desired positions beforehand, and the dam material 4 creeps into these holes. After that, a dam 5 is formed by hardening, based on heating or ultraviolet ray irradiation. Consequently, it becomes possible to stop the leaking and spreading of the molding sealing material over to the backside of the tape carrier package at desired positions.

IPC: G06V30/262
Filed: 1990-08-06
Abstract: PURPOSE:To easily retrieve picture information even if there is erroneous recognition at the time of generating index data by altering retrieval data in accordance with information on the erroneous recognition of a character. CONSTITUTION:A read part 2 transfers read data to a picture memory 3 and transmits a termination signal at the time of termination. A control part 1 transmits a recognition start signal to a character recognition part 4 after it receives the termination signal. The recognition part 4 recognizes having set data in the index area 3a of the memory 3 and transfers and a result to the control part 1. After reception, picture data and index data are recorded in a recording part 6. Then, index data in the recording part 6 is retrieved and the control part 1 transfers data to the memory 3 and displays it in a display part 5. Then, it is judged whether retrieval is to be continued or not. When there is no index data in the recording part 6, the control part 1 alters retrieval data and executes retrieval in accordance with retrieval data. Then, picture data recognized at the time of generating data can be retrieved at high speed.

Filed: 1989-08-11
Abstract: PURPOSE:To surely prevent the positional deviation of a chip due to mechanical vibration induced at the transfer of a board by a method wherein low melting point controllable collapse bonding(CCB) bumps are fused by heating to fix a chip temporarily to a board, and then the rest of the CCB bumps are fused by heating to mount the chip on the board. CONSTITUTION:CCB bumps 9a out of CCB bumps 9 are formed of material whose melting point is lower than that of material which forms the rest of the CCB bumps 9, and only the low melting point CCB bumps 9a are fused by heating to temporarily fix a chip 5 to a board 10 when the chip 5 is positioned on the board 5 by a chip mounting device 14, and the rest of the CCB bumps 9 are melted by heating in a reflow device to mount the chip 5 on the board 10. Therefore, the positional deviation of the chip 5 can be prevented from occurring due to mechanical vibrations induced at the transfer of the board 10 from the chip mounting device 14 to the reflow device. By this setup, the connection failure of CCB bumps can be surely prevented.

IPC: H04N5/907
Filed: 1988-08-19
Abstract: PURPOSE:To record or store a still picture with less deterioration in a picture caused by the movement of an object with simple constitution by detecting the movement of the object to control the write or recording of an input picture signal. CONSTITUTION:A picture signal inputted to a picture memory 1 is subject to write/readout control by a memory R/W controller 7 and displayed as a moving picture by an external display device (not shown). In the case of storing a still picture, a picture freeze command is given from a freeze command means 3 and sent to a threshold level circuit 5, then an output of the threshold level circuit 5 is enabled. Then a reference signal and an output of a movement detection means 2 are compared to discriminate the quantity of the movement of the object and the result is sent to a write inhibit gate 6. When the movement of the object is large, the write is not inhibited by the gate 6 and the moving picture display is continued as it is. When the movement of the object is small, the write to the picture memory 1 is inhibited and the picture is frozen.

Title: Acceleration sensor
Inventor: NAKAYAMA TOSHIYUKI
IPC: G01P15/18
Filed: 1990-08-06
Abstract: PURPOSE:To detect an acceleration component so accurately in a two-dimensional manner even in a very low frequency area by supporting such a force as acting on a pendulum body through acceleration, with a cylindrical high elastic material, while detecting the bending deformation of a cylinder by means of an optical means consisting of both light emitting and receiving means. CONSTITUTION:When force F acts on a pendulum body 8 in a certain direction according to acceleration and an elastic cylinder 7 is deformed to some extent by this force F, a light spot of a light emitting diode 17 so far converged on a central zero position of a PSD 10 by a lens 16 is shifted as far as a distance X in the working direction of the force F from the zero position P. This distance X is determined by the force F and an elastic stress in a high elastic material, measured by tests in advance and stored in a microprocessor unit in the form of a table. On the other hand, the PSD 10 is one made up of forming a semiconductor layer of P, I and N layers in order on a plate silicone surface and also forming a cathode electrode in a central zero position P of the N layer, through which an irradiating light spot flows right and left on a surface of the P layer, and an output current conformed to the distance can be taken out of right and left electrodes of respective X-Y axes, so that when there was a positional change in the light spot, a direction and a distance from the central zero position on a XY plane can be detected.

Title: Controller for induction motor for compressor
Inventor: TAZAWA TORU
IPC: H02P21/00
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce the vibration level of an induction motor, even when the motor is operated at a low frequency by using the sum of an average torque current command value and a load torque current command value which has the same period as the rotating period at an estimated speed as a torque current command value. SOLUTION: When, for example, the frequency of an induction motor for compressor drops to <=30 Hz, a load torque current commanding device conducts frequency analysis on an estimated speed ωme'. Since the estimated speed ωme' contains a pulsating component, a speed fluctuating period component, namely, an estimated average rotating speed component (period T) having a large peak is obtained. Then the amplitude of a load torque current, which fluctuates due to the ambient temperature, is optimized from the fluctuation of the estimated speed ωme'. In addition, the period pattern of the load torque current which has the amplitude optimized in the one-period pattern of the load torque current corresponding to a command speed ωme* and the load torque current command value having the period T of the estimated average rotating speed is generated.  Moreover, a phase timing such that the varying width of the estimated speed ωme' becomes smaller is decided and outputted from the load torque current commanding device.
