Title: Rotary head device
Inventor: FUJIKI MITSUHISA
IPC: G11B5/52
Filed: 1989-05-26
Abstract: PURPOSE:To effectively absorb torsional resonance and to hold the accuracy of rotor rotation high by providing an elastic member which energizes the rotor of a motor toward a fixed member and an adjusting member which varies the deflection quantity of the elastic member. CONSTITUTION:The adjusting member 10 and the elastic member 11 provided between the adjusting member 10 and rotor 9 are used to fix the fixing member 7 and the rotor 9 of the motor in the axial direction. The adjusting member 10 is moved in the axial direction with a screw part 4a and an adjusting nut 12 and the spring force of the elastic member 11 is adjusted. In this constitution, vibration generated on a rotary body is absorbed over a wide range in the rotating direction and a direction perpendicular to the shaft to prevent a torsional resonance phenomenon. Further, the energizing force of the rotor 9 to the fixing member 7 can be varied, so the most effective pressing force can be selected while the rotation accuracy of the motor and damping effect to a disturbance are confirmed.

Title: Character broadcasting receiver
Inventor: HENMI HIDEMI
IPC: H04N7/035
Filed: 1987-05-28
Abstract: PURPOSE:To reduce the waiting time of a request time and to improve operability and responsiveness, by accumulating and managing character broadcasting data sent at every vertical period in a buffer RAM by DMA(direct memory access), and performing the arbitration of a system bus with a microprocessor. CONSTITUTION:A character signal is sampled by a sampling part 1 as serial data, and error data is corrected by an error correction part 2, and it is converted to parallel data. A DMA/data management/bus arbitration part 11 transfers and manages error correction data from the error correction part 2 to the buffer RAM6 by the DMA. And, when the program of character broadcast is requested, a CPU3 makes access to the buffer RAM6. When a requested program exists, a DMA request is issued to the bus arbitration part 11. The bus arbitration part 11 outputs a hold signal, etc., to the CPU3, and performs DMA transfer from the buffer RAM6 to a work RAM5. When the DMA transfer is completed, the CPU3 performs decoding in order, and writes display data on a video RAM8 via a display control part 7, and displays a requested program on a display.

Title: Pin grid array structure lsi
Inventor: MIURA TAKEO
IPC: H05K3/34
Filed: 1995-05-31
Abstract: PURPOSE: To raise the positioning accuracy in mounting higher than a conventional one and facilitate the manufacture by using the same material, for a guide pin, as that of a lead material, and putting the base part in the shape of a pillar larger than the lead terminal, and tapering the tip beyond the pillar- shaped part. CONSTITUTION: Guide pins 11 circular in cross section are installed at the four corners of a package. This LSI is different from a conventional one in the point that the material of this guide pin 11 is the same as the material of a lead terminal 2 for signal processing, and in the point that the shape of the guide pin 11 is like a large pillar the tip beyond it is tapered 7. The guide pin 11 is thicker than a lead terminal roughly as far as the sum of the length of the lead terminal from the package and the thickness of a mounting board, and the tip beyond it is tapered conically. Hereby, a through hole 5 for positioning on the side of the mounting board guarantees easy insertion with a large clearance to the tip of the guide pin 11, and for the base part, the clearance is made small, whereby it guarantees the accuracy in positioning.

Title: Picture data transmission system
Inventor: TANJI NATSUKI
IPC: H04N19/00
Filed: 1987-05-28
Abstract: PURPOSE:To improve transmission efficiency, by dividing a data text into plural blocks, adding and sending an error detection code on every block, designating the block in which an error is detected, and sending again only the block in which the error is generated. CONSTITUTION:It is assumed that a transmission text is divided into, for example, 32 blocks. And it is sent after the identification number of the block and the error detecting code (BCC) are attached on every block. A reception side checks a transmission/reception text at every block, and when the error is detected, returns the list of the identification number of the block. A transmission side recovers the error by sending a re-transmission text consisting of only a data block in which the error is generated. Hereafter, the above re- transmission procedure is repeated until a text without the error is received. Thus, by re-sending only the data block in which the error is generated, it is possible to perform the transmission of picture data with superior efficiency.
