Title: Rinsing method for semiconductor wafer
Inventor: TAI TAKEKI
IPC: B08B3/02
Filed: 1986-03-28
Abstract: PURPOSE:To rinse effectively the surface of a semiconductor wafer, by spouting ice particles against the surface. CONSTITUTION:Liquid N2 is supplied in a vessel 1 up to about half depth, on the surface of which waves of several mm are generated by spraying N2 gas via a heat exchanger 5. From the upper part of the vessel 1, pure water is ejected with a specified pressure and flow rate, and fine ice particles 8 (lmum-5mm diameter) are formed. The ice particles are supplied to a hopper 10 and them ejected on a wafer 12 with CO2 gas having a specified pressure and flow rate. Fine contaminated particles 13 and stains are effectively blown off by the impacts of fine ice particles, and the melted water acts as a solvent for contamination materials. Therefor a brush is unnecessitated, so that the contamination caused by the wear of a brush and the grneration of electrostatic charge coused by the friction of a conductive brush can be avoided, and effective rinsing can be preformed.

Title: Microcomputer control circuit
Inventor: MATSUI YOSHITAKA
IPC: G06F12/06
Filed: 1988-03-23
Abstract: PURPOSE:To reduce the size of a program memory and to decrease a program miss by equipping a bank switching circuit to obtain the address output signal of a program counter as an input and a bank selecting signal as an output. CONSTITUTION:A program counter 1 counts the address of the program memory in a microcomputer control system and a bank switching circuit 2 inputs address data 5 of the program counter 1 and outputs a bank selecting signal 6 to select the arbitrary bank of a data memory 3. The bank selecting signal 6 of the data memory 3 is directly generated from the address information of the program counter 1 and it is not necessary to execute bank switching by a program instruction. Thus, the bank selecting signal of the data memory 3 is generated from the address information of the program counter 1 and the bank is switched. Thus, a bank register and a stack register are eliminated. Then, since the program of the bank switching is not needed, the length of the program is made short and the program miss is hardly occurred.

Title: Cleaning of felt for paper making and device for cleaning the felt
Inventor: KASHIDA MASAHIRO
IPC: B08B3/02
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To enable always the thoroughgoing cleaning of a felt for paper making by setting a cleaning pipe to slide vertically with a direction in which the felt for paper making moves and synchronizing the sliding speed of the cleaning pipe with the moving speed of the felt for paper making. SOLUTION: A cleaning pipe is set to slide C vertically with a direction B in which a felt 1 for paper making moves, and a sliding speed of the cleaning pipe 6 is synchronized with a moving speed of the felt 1 for paper making. That, is, at the mutually optimal values of the sliding speed for the cleaning pipe 6 and the moving speed for the felt 1 for paper making, a high-pressure cleaning water is jetted to the felt 1 in such a way that it has a constant period A for the track of cleaning water. Consequently, cleaning irregularities such that sufficient cleaning is partially not achieved on the felt 1 for paper making depending upon the moving speed of the felt 1, are eliminated. Therefore, the life of the felt 1 for paper making itself can be maintained for a long time.

Title: Production of forged article
Inventor: ASAHI SUMIO
IPC: B21J1/06
Filed: 1984-04-09
Abstract: PURPOSE:To lessen the generation of scales and to manufacture a forged article of good quality by heating and cutting a raw material for forging which is treated by preheating and charged into a hollow cylinder of a heating furnace so as not to form much surplus space on the periphery. CONSTITUTION:A forging material for forging preheated by a preheating furnace 1 is charged into a hollow cylinder 4 consisting of a refractory material of silicon carbide at the inside of a heating furnace 2 and heated to a forging temp. The hollow cylinder 4 has a slightly larger inner size of an axial line right angled direction than an outer size of axial line right angled direction of a supplied raw material for forging and is made that a surplus space around the raw material for forging is not formed much and that it is hardly exposed to an oxidized atmosphere. The heat treated raw material for forging is then fed into a cutting device 6 with a feeding-out device 5 and is fed to passing work via a taking-out channel 7. A forged article of no different quality from that forged by an electric furnace is thus manufactured at low cost.

Filed: 1985-04-04
Abstract: PURPOSE:To inhibit access of other CPUs to a shared memory when synchronization with the other CPUs is necessary, by providing the access controlling signal of the shared memory. CONSTITUTION:If an access controlling signal is not driven when a CPU 1 makes access to a designated area 5 of a shared memory after decoding an instruction and starting the process of TEST AND SET, the CPU 1 drives the access controlling signal.
