Title: Cathode-ray tube
Inventor: FUKUMIZU KEISUKE
IPC: H01J29/02
Filed: 1993-08-03
Abstract: PURPOSE:To provide a trinitron type cathode-ray tube that can reduce displacement of the landing position of an electron beam which changes as time elapses, after a power source is input. CONSTITUTION:The engagement surface between the inner surface of the tubular panel 7 of the spring 3 of a color selection mask 1 and a stud pin 9 is matched with a plane on which the longitudinal axis of the mask 1 is a normal. The spring 3 is loosened as shown by dots by thermally expanding the longitudinal axis side of the mask 1 during the main operational period of a cathode-ray tube after the power source is input. Since the spring 3 moves in circle or in the direction indicated by the arrow A around the stud pin 9 of the inner wall surface of the tubular panel 7, the arrangement of the mask 1 is changed not only in the longitudinal direction but also in the direction of a tube axis 11, and moves in the direction where GH becomes smaller, and the position 13 which an electron beam reaches toward the phosphor 12 of the inner surface of the tubular panel 7 is not easily affected by the deformation of a mask part 10. A GH correction mechanism by means of the thermal expansion of the color selection mask 1 which is the intrinsic characteristic of the corner shaft supporting method of the color selection mask 1 works sufficiently.

Title: Temperature sensitive resistor element for air flow measuring apparatus
Inventor: WATANABE IZUMI
IPC: G01P5/12
Filed: 1994-09-06
Abstract: PURPOSE: To form a multilayer polyimide film having no bubble nor pinhole by repeating the operation for applying and firing a polyimide resin several times while varying the density. CONSTITUTION: A solid alumina bobbin 9 applied with a thin platinum film 10 is press fitted, at bothe the ends thereof, with stainless steel caps 11, for example. It is then subjected to resistance trimming and a lead 12 is butt welded to each cap aligning with the bobbin axis then a multilayer polyimide film 8 is formed on the surface. When the multilayer film 8 is formed, a polyimide material liquid is diluted with a solvent and applied with 1-5 poise and then it is fired at 200 deg.C to evaporate the solvent sufficiently. The operation is repeated to cover the level difference between the end face of the cap 11 and the bobbin 9 and the trimming groove in the thin film 10. Subsequently, the dilution is changed to increase the density of polyimide resin.  For example, a polyimide liquid having viscosity of 30 poise and resin density of 25% is applied thick repetitively and fired finally at 300-400 deg.C thus stabilizing the film 8 chemically.

After a P<+> - diffusion layer 3 is formed and a rear is covered with photoresist, an extremely thin oxide film layer 4a is formed. After 10nm-thick n-type fine crystalline silicon 4 is formed and processed on the oxide film layer 4a by P-CVD method, an Sin, film 5 and a TiO2 , film are formed by CVD method under a normal pressure and are processed to form an electrode layer 7 to enable contact with the n<+> -diffusion layer 2. As for optical absorption by the fine crystalline silicon 4, optical loss in the part is at most 5% because of a thin film thickness. Therefore, a solar battery which can realize high photoelectronic conversion efficiency and a low cost can be constituted.

Title: Gas heater
Inventor: KODERA HIROSHI
IPC: F24C15/10
Filed: 1991-07-29
Abstract: PURPOSE:To obtain a gas heater which inhibits an increase in the temperature of its structural members to a relatively small value and prevents a change of color or soup from being scorched, keeping a fine outside view. CONSTITUTION:A flat burner plate 1 and a top board 17 for a heater body consist of a material having excellent thermal conductivity.

Title: Control circuit for drive of motor
Inventor: KAMATA TAKAO
IPC: H02P7/03
Filed: 1981-12-28
Abstract: PURPOSE:To prevent the flowing of abnormal large currents through a switching element by providing a circuit bypassing transient currents based on the inductance of the motor generated in case of the changeover of circuits. CONSTITUTION:When transistors 1, 6 are turned ON and 3, 4 OFF, the motor 9 is turned forward. The terminal voltage of a resistor 8 is detected at that time, and the transistor 1 is ON-OFF controlled by a chopper control section based on the voltage. When the transistors 1, 6 are turned OFF, transient currents based on the inductance of the motor 9 flow in the path of a diode 11, a power supply 7, a diode 14 and the motor 9. The transistor 6 is left as it is turned OFF because currents do not flow through the resistor 8 at that time. When the transistors 3, 4 are turned OFF, the motor 9 is reversed. Accordingly, circuits can rapidly be changed over smoothly.

Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To realize a double cavity type structure which has a simple structure and can reduce its size and weight at low cost by rotatably supporting an input side disc which is a second outer disc for a case directly or through a rotary shaft. SOLUTION: An input shaft 50 is supported by a bearing 54 in a through hole 53 of a first support wall 52 of a case 51 on one end side of a rotary transmission shaft 49. The other end part of the rotary transmission shaft 49 is supported by a bearing 59 which supports radial load and thrust load on an inner side of a bearing box 58 fixed on a second support wall 57 of the case 51. An inner peripheral face of an input side disc 2B is spline-engaged with an outer peripheral face of the rotary transmission shaft 49 to press an outer peripheral face of the input side disc 2B by a loading nut 62. Since the input side disc 2B is rotatably supported on a support wall 57 through the rotary transmission shaft 49, an intermediate wall becomes unnecessary, and the time and labor for manufacturing the case 51 can be saved.  Moreover, it is possible to reduce size and weight of a troidal continuously variable transmission by reducing the total length of a sleeve 41a and the rotary transmission shaft 49.
