Title: Manufacture of junction wafer
Inventor: ITO TATSUO
IPC: H01L21/762
Filed: 1997-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a junction wafer which is high in its bonding strength and the corrosion resistance of a junction interface to an etching solution. SOLUTION: The junction wafer 5 is obtained by forming an SiO2 , oxide film 3 one mirror surface side of a bond wafer 1, integrally overlapping the bond wafer 1 on a base wafer 2 (mirror surface wafer) so that the oxide film 3 becomes an intermediate layer, thermally oxidizing the integrated wafer in an oxidizing atmosphere for about 2 hours at temperatures of 900, 1000, 1100 and 1200'C to join the wafers 1 and 2 together, and polishing the bond wafer 1 into a thin film. The junction wafer can exhibit a bonding strength higher than 600kg/cm<2> , since the oxide film is formed only to the bond wafer and the integrated wafer is heated and joined at temperatures of 1100 to 1200 deg.C in an oxidizing atmosphere.

Title: Jitter suppression control method and its circuit
Inventor: SATOU SAKUTAROU
IPC: H04B10/07
Filed: 1994-09-02
Abstract: PURPOSE:To suppress jitter due to a pointer action by implementing phase control of an output clock signal in the unit of less than 1 bit. CONSTITUTION:A counter 22 controls a missing processing section 15 after lapse of a prescribed time to allow the section 15 to implement 1-bit missing processing of an input clock signal. That is, when an output of the counter 22 restores to 0.0, a carry out output CA is generated and fed to the processing section 15 via a differentiation circuit 26. Then a control voltage resulting from adding an offset voltage OFV from an inverting buffer amplifier 24 to a phase comparison output signal due to missing of 1-bit of the input clock signal is fed to a VCO 11. Since the offset voltage is gradually changed over plural steps, the output clock signal from the VCO 11 is gradually changed and when the processing section 15 executes 1-bit missing of the input clock signal, a phase of an output clock signal is changed already up to a 1-bit missing state. Thus, jitter due to 1-bit missing is suppressed.

Title: Sheathed heater and manufacture thereof
Inventor: SUZUKI TADAMI
IPC: H05B3/48
Filed: 1992-08-06
Abstract: PURPOSE:To unseal metallic pipe end parts, and prevent a heat resistant insulating characteristic from deteriorating even if it is used at a comparatively high temperature using electrical insulating powder formed by capsuling magnesia powder by means of metallic alkoxide. CONSTITUTION:A sheathed heater is composed of a metallic pipe 10, a heating wire 12 composed of a coil shape nichrome wire having terminal bars 11 on both ends and electrical insulating powder 15 formed by capsuling magnesia powder 13 by means of metallic alkoxide 14. In such constitution, since the magnesia powder is capsuled by means of the metallic alkoxide, infiltration of moisture can be prevented even in a high moisture resistant atmosphere, and a moisture resistant characteristics is improved significantly, and since a both end part sealing process of the metallic pipe 10 can be dispensed with, significant cost reduction can be realized.

Title: Evaluation method
Inventor: SUGIMOTO HAJIME
IPC: G01N33/15
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To permit proper evaluation by using an animal having a nude gene or immunodeficiency gene and having developed cancer and admistering the gene of this animal to a healthy animal to evaluate the carcinogenesis initiation and carcinogenesis promotion activity of a substance producing an antibody. SOLUTION: A nude mouse into which a nude gene is introduced is used to evaluate the carcinogenesis initiation and carcinogenesis promotion activity of a substance without considering a problem of the neutralization caused by the production of an antibody. In this evaluation method, an initial lesion, for example, a fine blister with a diameter of about 1 mm or less, a papule or flare can be observed by the naked eye and, when the administration of a carcinogenesis promotor is continued thereafter, a lesion occurs in many cases and a protruberance becomes marked to become a tumor before long. Therefore, the presence of an observable initial lesion is set to an index to enable the prevention or early medical treatment of cancer.

Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To facilitate the adjustment of a head gap such that a platen is fixed after moved up and down and to highly accurately hold the head gap. SOLUTION: A cam mechanism 61 composed of a combination of a fixed cam 62 and a movable cam 63 is interposed between both end parts of a platen 10 and a shaking frame 4.

When the movable cam 63 is revolved, the platen 10 is moved up and down along the fixed cam 62 to adjust the head gap to the printing head. The drive gear 64 becomes a state impossible to revolve by clamping a fixed screw 65 being a revolving shaft from above and the platen 10 is fixed.

Title: Height measuring device
Inventor: SOE MASAO
IPC: A61B5/107
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a height measuring device which can be set with less restriction of setting places. SOLUTION: A cursor 16 of this device is inverted L-shaped with a contact part 15 and an extended part 14 extended downward from the rear end of the contact part 15.

When erasing information, an electric field opposite to that at the time of writing is applied to and captured electrons are returned to the channel region. When reading information, judgment is made depending on presence or absence of current at the channel region when applying voltage between the drain and the source.
