Patent JP-H1130562-A (JP)
Title: Instrument
Inventor: YOGO TOSHIFUMI
IPC: G01L19/08
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To easily and accurately set the indication range that an instrument requires, with a section member, provided so that it can be operated from the outside its protection cover, without detaching a protection cover. SOLUTION: A slide groove 7 is formed between a case main body 2 and a transparent cover 4, and the top surface of the groove is made open, and a safety mark plate 5 is arranged inside it. Here, the top surface of the safety mark plate 5 is arranged below the case main body 2 and the top surface of the transparent cover 4. To set the proper range of pressure for the instrument, the safety mark plate 5 is operated from outside the transparent cover 4. Namely, the safety mark plate 5 can be moved without detaching the transparent cover 4 and the pressure range that the device requires can easily be set. Further, since the safety mark plate 5 is seldom touched carelessly from outside the transparent cover 4 after the setting, the accurate range can be held while being sectioned.

Title: Substrate holder for vapor growth apparatus
Inventor: CHIFUKU MASAYUKI
IPC: C23C16/458
Filed: 1981-11-26
Abstract: PURPOSE:To eliminate adverse effects of the deposit on a substrate holder exerted on a substrate crystal, by providing a projecting pedestal only at a substrate crystal retaining region on the substrate holer. CONSTITUTION:A substrate holder 1 has a projecting pedestal only in a region thereof for retaining a substrate crystal 2. Thereby, each substrate crystal 2 is allowed to be far away from the crystal material or the like deposited on the substrate holder 1 by the preceding vapor growth. As a result, there is no possibility that adverse effects of the deposit are exerted on the substrate crystal 2. Thus, it is possible to eliminate adverse effects of the deposit on the substrate holder exerted on the substrate crystal.

Title: Optical system control method of projection type television device
Inventor: NAKAMURA YOSHITAKA
IPC: H04N5/74
Filed: 1980-12-26
Abstract: PURPOSE:To facilitate the control of optical system for a projection type television device, by irradiating a test pattern to a target from outside and forming an image of the pattern on a screen. CONSTITUTION:The light delivered from a laser beam source 14 is deflected toward the XY direction by a light deflecting device 15 and projected on a target 3 of a cathode-ray tube 1 through a film 18 via an optical lens group 19 and a mirror 20. A compensating matter 11 is previously removed from a supporter 13, and a luminous point is formed at the center of the target 13 by means of the film 18 having a spot type pattern at its center. Then a valve 9 is fixed. A screen 21 is moved back and forth to perform the focal adjustment to the luminous point. Thereafter, the film 18 having a pattern of cross hatch, etc. is used to fix temporarily the matter 11 to the supporter 13, and the matter 11 is displaced to control the spherical aberration. Thus the matter 11 is fixed finally. In such way, the control is facilitated for an optical system.

Title: Heat resistant cap
Inventor: HAYASHIDA MITSUHARU
IPC: B65D47/08
Filed: 1994-08-10
Abstract: PURPOSE:To decrease a space formed to reduce amounts of heated liquid which is drawn in after the liquid has been charged into an article of commerce, thereby ensuring sanitary conditions, by pressing an inner leg of an outer cover against an inclined portion of a projection at a mount position. CONSTITUTION:Noodle soup or the like is heated to 70-90 deg.C to pasteurize it and charged into a container such as a bottle and a heat resistant cap is put on the container. At this moment, heat of the soup is transferred through the container or by convection to the air in a space 21 formed by an isolation wall 4, pouring out cylinder 2, and circumferential wall 15 of an outer cover 16, a space 22 between the cylinder 2 and an inner leg 18, and a space 23 between the leg 18, and a side wall 14 and a locking part 10 of an outer cover 16. And when warm water at a temperature of about 30 deg.C is showered on the outer cover 16 from the outside, the outermost space 23 is rapidly cooled so that the pressure therein is reduced, and hence the warm water is drawn in. However, the space 23 is made smaller by pressing the leg 18 against an inclined portion 12 of a projection 11 of the mount part 8, and hence reduction in the pressure due to the shower is very small. Thus the warm water is not practically drawn in.

Title: Method for monitoring trench forming process in real time at job site
Inventor: CANTELOUP JEAN
IPC: H01L21/3065
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a method by which a trench forming process can be monitored in real time at a job site. SOLUTION: A wafer is put in a plasma etching device (57) and plasma is generated (58). The surface of a wafer having a large area is irradiated with a radiant ray having a designated wavelength at a vertical incident angle through an inspection hole (59). Reflected light rays are collected and impressed upon a spectrometer and an interferometer type primary signal S is generated (60) and the signal S is simultaneously applied upon two filters (61). Of the two filters, a low-pass filter outputs first secondary signals S1 containing the data about the deposition speed and the thickness of a re-deposited layer and a band-pass filter outputs second secondary signals S2 containing the data about the etching rate and depth of a trench.  Thus the filtrated signals are monitored in a standardized way (62) and the thickness of the re-deposited SiO2 layer and trench forming parameters, such as the depth of the trench, etc., are accurately measured in real time so that the terminating point of etching can be decided accurately.
Patent JP-S5979380-A (JP)
Title: Scanning mechanism
Inventor: AOYAMA KEIICHI
IPC: G06V10/12
Filed: 1982-10-29
Abstract: PURPOSE:To scan written a character, graphic, etc., with a stable and high contrast irrespectively of the thickness of slips, by installing a scanning base which is formed by combining a transparent substrate, high-reflectivity material, and low-reflectivity material to the scanning mechanism of an optical character reader. CONSTITUTION:A scanning base 9 is formed by combining a transparent substrate 10, white or light-colored materials 11a and 11b, and black or dark- colored material 12. Since a line sensor scans the black material 12 through the transparent substrate 10 when no slip exists, a black signal is obtained. When a slip 3 is sent, the line sensor scans the white part of the slip 3 and a white signal is obtained. Moreover, the light passing through the slip 3 once pass through the substrate 10 and are reflected by the white materials 11a and 11b. The reflected light tend to penetrate again from the back to the surface of the slip 3. Therefore, the surface of the slip 3 has a light appearance and the contrast is improved. When such an arrangement is used, characters, graphics, etc., can be scanned with a stable and high contrast irrespectively of the thickness of the slip.
