Abstract: PURPOSE:To form a film having superior corrosion resistance, heat resistance and toughness by galvanizing an iron base, chromating it, coating the resulting chromate film with a heat resistant paint having a specified composition contg. Al powder, and baking the paint. CONSTITUTION:The surface of an iron base 1 is galvanized to form a Zn film 2 for preventing corrosion, and a chromate film 3 is formed on the film 2 by chromating as an under layer for giving a fine appearance and improving the adhesion. The chromate film 3 is coated with a heat resistant paint consisting of 10-15wt% Al powder, silicone resin, alkyd resin and an aromatic solvent, and the paint is baked to form a paint film 4. Since the chromate film 3 is protected with the paint film 4 contg. Al, the corrosion resistance, heat resistance and toughness are remarkably improved.

Abstract: PURPOSE:To prevent establishment of inter-row discharge interference by providing an electrode between electrode rows to shield the latter. CONSTITUTION:An electorde 4 of a metal plate is interposed between electrode rows 2 and 3 which are equipped with electrodes 1 at a preset pitch. If a voltage of preset level having no contribution to the recording operation is impressed upon the electrode 4, the electrode rows 2 and 3 are shielded by the electrode 4 so that the discharge between the rows 2 and 3 during the recording operation can be mutually interfered. As a result, it is possible to prevent establishment of irregularity in the recording density between the rows.

Title: Induction heating cooker
Inventor: NOMA HIROBUMI
IPC: H05B6/12
Filed: 1995-06-19
Abstract: PURPOSE: To enhance cooking performance by executing temperature control by a control temperature in response to the output of an inverter, which is set by a console panel, properly restraining the maximum temperature of loading, and also optimizing adjustment for loading temperatures. CONSTITUTION: The higher the output of an inverter 13 is, which is set by a console panel, the lower control temperature a memory circuit 19 stores. When the temperature detected by the thermister 18a of a temperature detecting means 18 exceeds a control temperature, a temperature control means 26 suspends the output of the thermister 13 or makes it low, and when the temperature detected is less than the control temperature, the aforesaid means makes the output of the inverter 13 high. By this constitution, if the detected temperature exceeds the control temperature, heating is thereby suspended, even if the output is high, and the maximum temperature of loading 16 can thereby be restrained. In addition, the stable temperature of loading 16 can be made high by making a set output low, cooking performance for frying foods can thereby be enhanced.

As a result, the stable emission characteristic is maintained for a long time, and the reliability is improved. Scandium salt is preferable for the rare earth metal salt, and nickel is preferable for the substrate metal.

Abstract: PROBLEM TO BE SOLVED: To stabilize the dimensional accuracy of a prism-like projecting section when an inductor of obtaining a prescribed DC superposing characteristic is constituted, by forming the projecting section having a cross-sectional area smaller than that of the cylindrical section of the center leg of an E magnetic core having the center leg at the front end section of the magnetic core. SOLUTION: A magnetic core 1 is formed in an E magnetic core having a cylindrical center leg 2, and a prism-like projecting section 4 is formed at the front end section of the center leg 2. The projecting section 4 is formed in the outer peripheral circle of the leg 2 so that the cross-sectional area of the section 4 may become smaller than that of the cylindrical section of the leg 2. In addition, the projecting section 4 of the leg 2 is formed on a first projecting section 5 having a pair of parallel pieces 5a. Since the first projecting section 5 having the paired parallel pieces 5a is provided on the center leg 2, and a second projecting section 4 is formed against the first projecting section 5, the characteristics variation of the magnetic core caused by the displacement of the second projecting section 4 when the second projecting section 4 is formed can be prevented.

Title: Plane type display device
Inventor: GOTO KEIJI
IPC: H01J31/10
Filed: 1986-06-30
Abstract: PURPOSE:To enable low powered and stabilized control operation by fixing electrode groups and electrodes through spherical insulators. CONSTITUTION:Control electrodes are constructed by inserting spherical insulating spacers 11... into the spaces between both ribbonlike electrodes 112 and 142. As for the spherical insulating spacers 11, glass beads are used and on the surface of which frit glass layer 12 is coated to fix the glass bead to the ribbonlike electrodes. As the contact area between the glass bead and the control electrodes is quite small, so that capacitance between the control electrodes is lowered to less than 1/10 of that of conventional device using insulating support plates. Thereby the charging up on the glass bead can be avoided, and the control operation can be performed with low power and high stability.

Title: Fiber for optical energy transmission
Inventor: ASHIDA NORIYUKI
IPC: G02B6/44
Filed: 1985-07-09
Abstract: PURPOSE:To reduce the leak of light in input and output terminals by coating fiber side faces near input and output terminal faces of an optical fiber with a metallic layer whose reflection factor of light is >=95% with respect to the wavelength of a related light. CONSTITUTION:An optical fiber 1 is the fiber for energy transmission, and an optical fiber end face 4 is the input or output terminal. A cylindrical metallic layer 2 having a uniform thickness and a conical metallic layer 3 whose thick ness is reduced to zero gradually are provided in order from the optical fiber end face 4. If a layer surface 8 on the side opposite to the metallic layer is rugged, the light leaked to this rugged part is absorbed strongly by the rugged ness to reduce considerably a maximum transmission power. Since it is difficult to form the layer surface 8 perpendicular to the outside peripheral surface of the optical fiber to a flat surface, the thickness of the layer is reduced gradu ally. Gold, silver, aluminum, or the like which has >=95% reflection factor for the wavelength of transmitted light is used as materials of the metallic layer. Thus, the light is less leaked in the intermediate part and the ligth is transmit ted stably.

Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a seismoscope capable of detecting low-frequency vibration and capable of performing detection at a low magnetic field intensity. SOLUTION: An iron core 1 made out of ferrous amorphous metal material is inserted into the axial hole 2a of a coil bobbin 2, and a coil block 14 composed by winding a coil 3 is put inside a movable yoke 5. A movable block 7 composed of the movable yoke 5 and the coil block 14 is hung down from a lid with a hanging wire 6 in a freely swayable way. On the bottom of a body 9, a stationary yoke 8 in the shape of a closed-end cylinder on which a permanent magnet 4 is put in the center is arranged. If a movable block 7 shakes the permanent magnet 4 and the upper part of the stationary yoke 8 in accordance with the vibration of an earthquake, the direction of magnetic flux Φpassing through the iron core 1 inverts rapidly by a large Barkhausen effect.  As the result, a pulselike voltage not depending on the frequency of the vibration is generated in the coil 3 by Matteuci effect, and detection of the vibration of the earthquake becomes feasible.
