Title: Input and output control unit and method for system lsi
Inventor: KAWAHARA NOBURO
IPC: G06F13/36
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To effectively utilize all mounted interfaces without causing any problem between modules to be mounted on a system LSI and the corresponding input and output pin. SOLUTION: At the time of data transmission and reception, communication control interface modules 102-105 output bus capture request signals 108-111 to an arbiter 106. The arbiter 106 operates arbitration, and outputs bus permission signals 108-111 to the module which is permitted to use a bus 118. The module which is permitted by this signal can perform access by apparently using an input and output pin 127 exclusively for the interface without any protocol conversion by using the input and output signals of an LSI 101. Also, the arbiter 106 communicates which interface is selected to the outside part.

IPC: G11B15/087
Filed: 1981-07-02
Abstract: PURPOSE:To perform stable joint pickup without color beat, by taking a joint pickup start track as the next track to the final track of a signal recorded previously. CONSTITUTION:When the pause is released, a signal reproduced from a video head 18 is inputted to a low pass filter 32, a high pass filter 33, and a band pass filter 34 via a preamplifier 31. A reproduced FM luminance signal from the high pass filter 33 is demodulated at an FM demodulator and a vertical synchronizing signal is separated at a vertical synchronizing separation circuit 36. A joint pickup signal is introduced from the band pass filter 34 and detection processing is made at a wave detector 37 only for the synchronizing signal period. The output of the wave detector 37 is given to a Schmitt circuit 38 and this output clears a counter 39. After the counter 39 is cleared, the counter starts counting of vertical synchronizing signals and when a specified number is counted, a system controller of a VTR is switched.

Title: Optical information recording medium
Inventor: TOMURA TATSUYA
IPC: G11B7/24097
Filed: 1991-04-08
Abstract: PURPOSE:To enhance the accuracy in analyzing the defect of an optical information recording medium without relaying on the accuracy in setting the medium on a detect inspecting machine and to improve productivity. CONSTITUTION:A defect mark 5 is previously put on the non-recording region 3 on the inner peripheral side of an optical information recording medium or on the non-recording region 4 on the peripheral side.

Abstract: PURPOSE:To make current amplifying rates of respective N-P-N transistors, in an 1<2>L element provided with a plurality of collectors formed on an N-P-N transistor, equall to each other, by a method wherein the depth of a base diffused layer is so determined that the closer to an injector, the deeper the base diffused layer regions. CONSTITUTION:In a diffusion process of a base layer of an 1<2>L, wherein the base region of a vertical type N-P-N transistor and the emitter of a horizontal type P-N-P transistor are made common to each other, windows are formed in an oxide film 1 to diffuse a P type impurity, for example, B. When the windows are photo-etched, the oxide film 1 on an injector region 13 and the base region 11 closer to the injector is completely removed, and a thin oxide film 12 is left in the region remote from the injector. Thereby, the junction depth of a base diffused layer 14 close to the injector is formed deeper than that of a remote region 15, so that, the base resistance of said region decreeses. Accordingly, the current amplifying rates of a plurality of emitters are made equall to each other.
