Inventor: KOYAMA TADASHI
IPC: F16J15/34
Filed: 1986-10-15
Abstract: PURPOSE:To prevent the stagnation of contaminated shaft sealing liquid, by providing shaft sealing liquid inlet and outlet ports below the sliding surface on the lower side of a shaft sealing chamber, and providing a shaft sealing liquid draw-out pipe in the shaft sealing chamber on the shaft sealing liquid outlet side. CONSTITUTION:An inner rotating ring 3 and an outer rotating ring 4 are incorporated in a shaft sealing chamber part 23, and shaft sealing liquid inlet and outlet ports 21, 22 are provided in a fixed seat 14. The shaft sealing liquid flowed in from the shaft sealing liquid inlet port 21, after filling the shaft sealing chamber 23, passes through a draw-out pipe 11, and flows out from the shaft sealing liquid outlet port 22. The deposit such as wear powder accumulated at the bottom of the shaft sealing chamber 23 is discharged by circulating the shaft sealing liquid in the reverse direction at a given interval. Thus, the stagnation of contaminated shaft sealing liquid can be prevented.

Title: Printed wiring board
Inventor: MORITA TOMOHIRO
IPC: H05K3/42
Filed: 1991-09-24
Abstract: PURPOSE:To enable smooth mounting of components onto a printed wiring board by stepping a wiring zone and a throughhole zone on the board with a copper foil and plating copper. CONSTITUTION:After a throughhole 3 is opened in a copper-clad laminated plate 1 clad-with a copper foil 2, an etching resist 8 is spread over a part to leave the copper foil as a wiring pattern. At this time, the periphery A of a throughhole serving as a component hole is not etched; then, for a next etching, the copper foil around a throughhole is removed. After an etching resist remaining on the board is peeled off, a plating resist 9 is spread and further subjected to electroless copper plating. In this step of electroless copper plating, a copper plating film 10 is spread and develops a step of copper plating as shown by B. Thus, the inlet of a throughhole shows a bowl shape with the result that components can be mounted onto a printed wiring board smoothly.

Title: Method of automatically peeling slice base
Inventor: YOSHIDA YUICHI
IPC: H01L21/304
Filed: 1993-09-29
Abstract: PURPOSE:To enable excellent slice base peeling, by detecting the load at the time of press peeling of a slice base, and controlling the temperature in a water tank according to the detected load. CONSTITUTION:After a sliced semiconductor wafer 100 to which a slice base 200 is bonded is dipped in a hot water tank 10, the slice base is peeled. In this method, the load at the time of press peeling is measured with a load sensor 1 installed on a peeling cutter 4. When the load exceeds the upper limit of a previously set load range, the water temperature in the hot water tank 10 is raised by increasing the temperature of a heater unit 12 which supplies hot water to the tank 10. When the load falls short of the lower limit of the set load range, the water temperature in the tank 10 is reduced by supplying pure water from a water feeding pipe 15 by opening a valve 13. Thereby the slice base peeling from a wafer is stably enabled.

Title: Apparatus for automatically treating long steel material
Inventor: MIYAGAWA KAZUO
IPC: G01N21/88
Filed: 1984-11-21
Abstract: PURPOSE:To enhance positional accuracy, in flaw detection using a magnetic powder, by vibrating the surface image of an object to be inspected to enhance the contrast of a flaw indicating pattern and determining the position of a flaw from the number of counts of vertical and horizontal synchronous pulses at the time of the generation of a flaw signal. CONSTITUTION:At first, a reflective mirror 29 is vibrated and the contrast of the flaw indicating pattern of an object B to be inspected is enhanced to perform flaw detection using a magnetic powder and the surface image of the object B to be inspected is picked up by a TV camera 22. This video signal is divided into two by a flaw signal grocessing apparatus 39 and one signal is taken out as a flaw signal by a binarization circuit 42 to be guided to an AND circuit 55. The other signal is synchronously separated by a synchronous separation circuit 44 to reach vertical and horizontal synchronous circuits 45, 46. A vertical synchronous pulse is set as a start point to count a horizontal synchronous pulse by a counter 47 to obtain a predetermined horizontal scanning line. An oscillator 52 outputs a pulse, which is synchronous to the horizontal synchronous signal and obtained by the frequency dividing of a signal with frequency N-times that of said synchronous signal, through a counter 53 to divide the horizontal synchronous signal into (N) signals by a divider 49. When this output is applied to a circuit 55 and AND with a flaw signal is taken, the position of a flaw is determined by the above mentioned number of counts at the output time of AND.

Title: Convergence correction circuit for projection type receiver
Inventor: YOSHIDA AKIRA
IPC: H04N9/31
Filed: 1990-09-13
Abstract: PURPOSE:To reduce deviation in a pattern from its center due to automatic convergence when a high voltage power supply to a projection tube is decreased at a high brightness and an amplitude on a pattern is expanded by selecting a generating address of a pattern signal for detecting mis-convergence in response to a high detection voltage fed to the projection tube.
