Patent JP-H0493031-A (JP)
Title: Semiconductor silicon substrate
Inventor: SAKAMOTO MITSURU
IPC: H01L21/205
Filed: 1990-08-09
Abstract: PURPOSE:To improve semiconductor device yield by using a semiconductor substrate mirror-finished on both sides, providing denuded layers entirely on both sides of the substrate, and providing a gettering region containing oxygen precipitates within the substrate. CONSTITUTION:A silicon substrate 1 includes a gettering region 5 for holding impurity. Both surfaces of the substrate, having a mirror finish, are provided with denuded crystalline layers 2 and 3 of good quality without oxygen precipitates, respectively. The gettering region 5 is formed of precipitates of a predetermined oxygen content in the substrate, and of crystal defects. The denuded layer 2 and 3 are formed by placing the mirror-finished substrate in a high-temperature furnace to force oxygen atoms in the substrate to diffuse outside the substrate. These denuded layers are of high quality and free from oxygen precipitates, and they are 10-60 microns thick.

Title: Self-suction type pump
Inventor: WATANABE MICHIO
IPC: F04D9/02
Filed: 1983-11-10
Abstract: PURPOSE:To make the automation of on-off operation for a water passage attainable, by installing an elastic body which energizes a plunger in a direction to separate it from an opening end at the side of an air separation chamber, while constituting the plunger so as to close the opening end upon receiving the discharge pressure acting on the air separation chamber. CONSTITUTION:When operation takes place after putting reserve water into a pump, a plunger 12 inside an air separation chamber 7 is supported by dint of the energizing force of an elastic body 11, while an opening end at the side of the air separation chamber 7 in a return water passage 9 is opened whereby the reserve water passes the water passage 9, separates air at the air separation chamber 7 and takes out the air in a suction water passage. Then, water is filled up in the air separation chamber 7 and discharge pressure F is added to the inside of the separation chamber 7 or the upper side of the plunger 12. This force F and another force to pull in the plunger 12 produced by water running inside the water passage 9 are joined together so that this combined force overcomes the energizing force of the elastic body 11, thus the automation of on- off operation for the water passage is made attainable.

Filed: 1994-09-05
Abstract: PURPOSE: To make the shape of an image projection device thin and to reduce the nonuniformity of the luminance of a projected image on a screen by dividing the reflecting mirror of a projection optical system. CONSTITUTION: By bisected reflecting mirrors 4 and 11, a light beam emitted from a pixel between the pixels A-C and B-C of a liquid crystal original image is reflected toward the next bisected plane reflecting mirrors 5 and 15. The image of the light beam 9 emitted from the liquid crystal original image and reflected on the mirror 5 is formed on the screen 10 as the light beam from the virtual image 6 of an original image and the virtual image 7 of a convergent optical system. Similarly, the image of the light beam 14 emitted from the liquid crystal original image and reflected by the mirror 15 is formed on the screen 10 as the light beam from the virtual image 12 of the original image and the virtual image 13 of the convergent optical system.  Since the depth of the device is made thin and the incident angles of the light beams 8 and 14 are made to be more vertical by using the divided plane mirrors 5 and 15 in such a way, the luminance of the reproduced image on the screen is uniformized.

Meanwhile the synchronization of frequency is secured by a PLL consisting of a mixer 30, a local oscillator 29 and an LPF 36. The received signal which is converted into an x-bit parallel digital signal by an A/D converter 31 is inputted to one of both ports of a multiplication accumulator 33. The diffusion code which is multiplied by the digital received signal is inputted to the other input port of the accumulator 33 through a ROM 32 and outputted as a demodulation signal.
