Title: System for data protection of data transfer control
Inventor: II TOSHIAKI
IPC: G06F13/00
Filed: 1980-12-29
Abstract: PURPOSE:To prevent the destruction of data in course of read, by holding the set timing of status information when a set request is issued from an input/output device during the status information read of a main processing device and by setting information from the input/output device after the read. CONSTITUTION:An input/output control device 2 is provided between an input/ output device 1 and a CPU3 as a main processing device including a memory 4, and status data 7 from the device 1 is set to a status register 9. Status information is read through a driver 11 at a prescribed timing by the CPU3.

IPC: H04N5/44
Filed: 1992-07-15
Abstract: PURPOSE:To obtain the inexpensive and economical signal separator circuit by applying time division to an output of a signal storage means, inputting an input signal to a main part signal processing means for a transmission period of a main part signal, selecting a mask part signal processing means and inputting the input signal to the selected processing means for a transmission period of a mask part signal so as to use the signal storage means in common thereby reducing number of delay circuits required for signal processing. CONSTITUTION:An input signal is inputted to a memory 200, and a changeover device 201 controlled by a control circuit 204 switches the circuit for the input signal so that the input signal stored in the memory 200 is fed to a main part signal processing circuit 202 for a period when a main part signal is sent and to a mask part signal processing circuit 203 for a period when a mask part signal is sent. The entire memory capacity is reduced by using the memory 200 in common for the main part signal and the mask part signal in this way. Thus, the number of delay circuits required for processing the television signal sent in the letter box system is reduced while being separated into the main part and the mask part.

Title: Joint ring for horizontal and continuous casting machine
Inventor: KAKIHARA YOSHIHITO
IPC: B22D11/04
Filed: 1985-08-26
Abstract: PURPOSE:To decrease the cold shut of an ingot by maintaining a specified small spacing between the outside circumference of a cylindrical mail ring part and the inside surface of a female ring and constituting a joint ring in such a manner that the female ring is housed into the receiving seat part of a casting mold by a loose fit. CONSTITUTION:The joint ring 15 is constituted of the male ring 16 and female ring 17 made of a refractory material. The male ring 16 is formed of a cylindrical part 16a and flange part 16b which are made into the integral L-section having an obtuse- angled inside corner. The male ring 16 is formed to the angular section at which said ring is fitted to the outside circumference of the cylindrical part 16a. A projecting angle corner 17a of the female ring 17 makes point contact with a recessed angular corner 16c of the male ring 16 when the attraction force in the axial line direction acts between both by the tightening force to assemble the mold. The female ring 17 is housed, by a loose fit, into the receiving seat part 18 of approximately the same shape as the cross sectional shape of said ring formed to the inside circumference at the inflow port end of the mold 1. The heat transmission is thereby decreased and since the top end of the male ring 16 of the joint ring is maintained at a high temp. by heat insulation, the cold shut of the ingot is decreased.

Title: Preconditioning of shielding or clamping ring
Inventor: DONARUDO EMU MINTSU
IPC: C23C14/02
Filed: 1993-07-29
Abstract: PURPOSE: To pretreat a shield or clamping ring before use in a physical vapor deposition process so as to prolong the interval of mending or exchange.  
     CONSTITUTION: The shield or clamping ring is first bead blasted using an abrasive powder, then is treated in an ultrasonic cleaning chamber to remove loosely deposited particles and then sputter etched or treated with a plasma. As a result, the contamination which may form a diffusion barrier is loosened and the bonding of the deposits to the shield is prevented and the surface thereof is roughened. As a result, the process decreases boundary pores and improves the deposition of sputtered materials on the shield or clamping ring. As a result, the time before the cleaning of the shield/clamping ring is made necessary is prolonged and the down-time of the physical vapor deposition is reduced.
