Title: Formation of metallic film by sputtering
Inventor: KITAHARA TAKAAKI
IPC: C23C14/02
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce defects in wiring resistance or the like by previously executing dammy sputtering or the like to a jig and coating the jig and the inside wall of a chamber with the film of the material the same as that of a metallic film formed on a substrate. SOLUTION: A jig 1 set with a dammy substrate 2 is charged to a device, and Cr sputtering (dammy sputtering) is executed. By this dammy sputtering, Cr sputtered from a Cr target 6 is adhered to the inside wall 3 of the chamber, the jig 1, a shutter 5 or the like. Next, a product substrate 4 is set to the jig 1, and Cr sputtering is executed. At this time, the product substrate 4 is subjected to reverse sputtering from the chamber inside wall 3, jig 1, shutter 5 or the like by the sputter etching or sputtering, but, since Cr is adhered to the chamber inside wall 3 or the like, the bad influence of the product substrate on the Cr film quality is small. In this way, the quality of the film formed on the substrate can be stabilized.

Title: Reading and recording device
Inventor: SHIBAKITA SHUNEI
IPC: H04N1/00
Filed: 1986-03-11
Abstract: PURPOSE:To scale down a reading and recording part by integrally forming a contact type image sensor and a thermal head. CONSTITUTION:The contact type image sensor and the thermal head are integrally formed. For reading an original, a reading and recording unit 1 is brought into contact with the side of a reading conveyance roller 5 with pressure. the originals placed on an original table 12 are separated one by one by an original separation roller 3, and read at the position of the read conveyance roller 5, after which an original discharge roller 6 discharges said originals to a stacker 13. In the middle of reading, a recording conveyance roller 8 rotates in a reverse direction, however it has no conveyance force because it is not pressed on the thermal head. Accordingly the tip of a recoriding paper stops just before a cutter 9. In order to start recording, the reading and recording unit 1 is contacted the recording conveyance roller 8 with pressure, and a motor is normally rotated to send the recording paper in the reverse direction. Then the tip of the recording paper is rewound at the recording position of the reading and recording unit 1.

Title: Production of sanitary pottery
Inventor: MIZUNO HARUYUKI
IPC: C04B35/632
Filed: 1994-02-23
Abstract: PURPOSE:To enhance a strength of a sanitary pottery by incorporating an alumina in a slurry. CONSTITUTION:At the lime of casting a sanitary pottery, after a slurry is previously prepared to have a predetermined composition, an alumina is added to the slurry. In this manner, an optimum condition for adding an alumina can be easily found. Therefore, a product strength can be efficiently enhanced. The loading amount of the alumina is desirably approximately 10% or more (outer percentage), more desirably approximately 20% or more. The particle diameter (average particle diameter) of the alumina is preferably approximately 1-4mum. The material can be ideally casted by adding a deflocculant in combination with the alumina. After that, the casted item is dried and calcined. In this manner, a product strength can be enhanced, and a thin-wall and light- weight sanitary pottery can be obtained.

Abstract: PURPOSE:To obviate dissipation of a hologram in spite of preservation in a dark place and to prevent limitation on diffraction efficiency by raising the temp. of a recording medium to the extent of not exceeding the phase transition temp. of the ferrodielectric and paradielectric substance of the material of the recording medium at the time of writing the hologram. CONSTITUTION:The temp. of the recording medium 12 is heated by a heater 13 to the temp. of not exceeding the phase transition temp. of the ferrodielectric and paradielectric substance of the material of the recording medium and is further held to maintain the specified temp. Next, a shutter 3 and a shutter 5 are opened and desired information is imparted to object light 16 by an air modulator 9, by which the recording medium 12 is simultaneously exposed with the object light 16 and reference light 17. The shutter 3 and the shutter 5 are thereafter closed and in succession, the heater 13 is turned off to lower the temp. down to room temp. The shutter 3 is then opened and the hologram is reconstructed where the temp. settles down. The temp. at the time of the reproduction is kept in a temp. range below the temp. at the time of recording and above the absolute zero degree.

Title: Angular velocity sensor
Inventor: BABA HIROYUKI
IPC: G01C19/5642
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a relatively inexpensive high-sensitivity high-accuracy angular velocity sensor. SOLUTION: An angular velocity sensor is constituted in such a way that a bimorph is constituted by sticking piezoelectric elements 11 and 12 to each other and an equilateral triangle pole having a bottom face perpendicular to the stuck joint surface A of the elements 11 and 12 is formed by segmenting the bimorph. Then the triangle pole is fixed on a base 15 integrated with or separated from a piezoelectric element and independent electrical electrodes Ad, Bd, C1d, and C2d are respectively formed on the joint surface A and the surfaces B, C1, and C2 of the triangle pole. In addition, the electrodes Bd, C1d, and C2d of the triangle pole and the electrode Ad on the joint surface A are polarized and the triangle pole is set to an excited state by driving the pole in the direction of the joint surface A by impressing an AC voltage upon each electrode.  Then the output of the sensor caused by a Coriolis force is fetched by fetching the output difference of the electromotive force of the bimorph at the electrodes C1 and C2d in the direction perpendicular to the exciting direction.

Abstract: PURPOSE:To stabilize speedily the room temperature in a room to be air-conditioned and enhance comfortableness, by providing a blower controller for controlling the rotational frequency of a room-side blower according to the difference between a pressure detected by a pressure detector at a common passage part for a cold air flow or a hot air flow and a pressure set on a pressure setter, and a timer for suspending the detection of the pressure difference for a predetermined time. CONSTITUTION:With an air quantity varied, the exterior static pressure in a branching chamber 10 is varied, and upon detection of this pressure change by a pressure detector 25, the rotational frequency of a room-side blower 2 is varied by a blower controller 2a to perform such a control as to return to a set exterior static pressure. At this time, a timer 26 is operated to suspend the detection of pressure by the pressure detector 25 for a predetermined time (e.g., 3min). By this, the blower 2 is permitted to rotate at a fixed rotational frequency for the predetermined time. Next, when the predetermined time is counted up by the timer 26, the detector 25 again performs pressure detection, and the rotational frequency of the blower 2 is controlled by the controller 2a so as to obtain the set external static pressure. Thus, an appropriate air quantity is speedily obtained, and the temperature in a room to be air-conditioned is speedily stabilized.
