Title: High-frequency heating device
Inventor: KUBOTA TETSUO
IPC: F24C7/02
Filed: 1987-03-05
Abstract: PURPOSE:To positively seal high-frequency energies by penetrating spiral lead wires spaced apart in coil pitch via a support tool through a link provided inside a heating chamber wall surface, and setting the dimension of the entire part of the spiral lead wires sufficiently small than the wavelength. CONSTITUTION:Spiral lead wires 7 spaced apart from spiral heater wires 3 in coil pitch via a lead wire support tool 8 and a heater support tube 6. In this case at least one winding of spiral lead wires 7 is allowed to exist in the link 5, and the dimension (length) of the entire part of the lead wires 7 is set sufficiently smaller than the wavelength (approximately 120 mm). Thus, the link part 5 and the spiral lead wires 7 do not constitute a coaxial transmission line, and the leakage of high-frequency energies from the end part of a grill heater 4 do not occur. Thus, a positive sealing effect can be obtained by a compact structure.

Abstract: PURPOSE:To detect properly the density of a reference pattern image irrespective of the type of toner by switching such that a light receiving element receives a normal reflected light beam and an irregular reflected light beam when black and color toners are used for development, respectively. CONSTITUTION:When a developing unit 5 filled with the black toner is loaded, a solenoid 42 is turned off to return a plunger 43 upward, and in terms of respective elements 26 and 27, the latter 27 is set to a position where it can receive the normal reflected light beam of the light irradiation of the light emitting element 26 with respect to the surface of a photosensitive body drum 2. On the other hand, when a switch 51 is turned off, that is, the developing unit 5 is exchanged with that filled with the color toner, the solenoid 42 is turned on to move the plunger 43 downward, and in terms of the elements 26 and 27 the latter is set to the position where it can receive the irregular reflected light beam of the light irradiation of the light emitting element 26 with respect to the surface of the photosensitive body drum 2. Either case ensures the sufficient correlation between the output of the light receiving element 27 and the toner concentration, and the toner concentration can be properly detected.

Title: Keyboard
Inventor: KAINUMA KEIJI
IPC: G06F3/041
Filed: 1989-03-03
Abstract: PURPOSE:To prevent the malfunctions due to the defective touches of switch contacts and to improve the reliability with a thin and light-weight keyboard by controlling a key matrix part based on the outputs of a press point detecting part and a key area memory part. CONSTITUTION:A finger press point detecting part 2 detects a pushed point on a touch screen 1 and outputs a signal to show the detected point. A keymatrix control part 4 compares the position information on the pushed point with the information on a cross point area of a key area memory part 3 and outputs a signal to specify a cross point corresponding to a pushed key. A key matrix part 5 inputs the output signal of the part 4 to turn on a matrix switch of the cross point and outputs the corresponding key signal via an output interface part 6. As a result, the malfunctions due to the defective touches can be eliminated for improvement of the reliability of a keyboard. Furthermore the thickness and the weight of the keyboard are reduced by packing its component parts into a single sheet of a printed board.

Title: Production of speaker diaphragm
Inventor: OKUMURA MASATOMI
IPC: H04R31/00
Filed: 1982-03-30
Abstract: PURPOSE:To stick tightly alumina to a base material without applying a plast process, by melt-spraying aluminum or a mixture obtained by adding <=30wt% alumina to the aluminum in order to form an intermediate layer. CONSTITUTION:An aluminum base material 1 is formed into a dome and washed. A mixture obtained by adding 15% alumina to aluminum is melt- sprayed to the washed material 1 to form an intermediate layer 3 on the surface of the material 1. Then alumina is melt-sprayed on the layer 3 to form an alumina layer 2. Thus both expansion and shrinkage factors due to the heat produced by the melt-spraying process are almost equal between the material 1 and the mixture since the primary component of the mixture is aluminum. This minimizes the generation of stress. In addition, the coupling force is extremely intensified between the layers 3 and 2 since the empty holes of the layer 3 absorb the stress produced between both layers and at the same time the rough surface of the layer 3 increases the biting and contact areas between both layers.
