Title: Refrigerant heating type air conditioner
Inventor: KOTANI NAOKI
IPC: F24F11/02
Filed: 1988-10-17
Abstract: PURPOSE:To change the burning rate of a burner to two steps i.e. strong combustion and weak combustion, and to widen the range of operating an air conditioner by disposing a thermostat at the refrigerant outlet port of a heater. CONSTITUTION:Refrigerant introduced through a refrigerant inlet port 11a is heated by a burner 13 at a heater 11 to be converted into heated gas and is fed through a refrigerant outlet port 11b into an indoor device where heat is radiated. Condensed refrigerant is thereby converted into a liquid state, and the resultant refrigerant is introduced through the refrigerant inlet port 11a and is heated again at the heater 13. When a temperature at the refrigerant outlet port 11b of the heater 11 rises to 65 deg.C or higher due to refrigerant and a thermistor 15 detects this temperature, a signal produced by the thermistor is judged and sent by a judgement means 16, so that a gas solenoid valve 17 is actuated toward a 'closing' by means of a solenoid valve drive circuit, whereby the amount of gas to be fed is decreased to result in weak combustion. When the temperature of heated gas is lowered due to continuous weak combustion to cause the lowering of a temperature at the refrigerant outlet port 11b and the thermistor 15 detects the temperature of not more than 60 deg.C, a signal produced by the thermistor is judged and sent by the judgement means 16, so that the gas solenoid valve 17 is actuated toward an 'opening' by means of the solenoid valve drive circuit, thereby resulting in strong combustion.

Title: Sic-aln-based composite raw material and its production
Inventor: U KEIKON
IPC: C04B35/581
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain a high quality raw material for ceramics and refractories by adding a carbonaceous material to an alumina-silica-based refractory raw material such as agalmatolite or clay, especially a low grade raw material containing alkali components comprising Na and K and subsequently thermally treating the mixture. SOLUTION: This ultrafine SiC-AlN-based composite raw material powder is obtained by reducing Al2O3 and SiO2 contained in an alumina-silicabased refractory raw material with gaseous nitrogen and carbon contained in a carbonaceous material. When the alumina-silica-based refractory raw material contains K and Na components, the crystal structures of the Al2O3 and SiO2 are perfectly decomposed. Thereby, the K and Na components contained in crystals are oxidized into K2O and Na2O and evaporated off as gases. The alumina-silica-based refractory raw material includes natural minerals and synthetic minerals, and alumina-silica-containing materials such as brick scraps and industrial wastes can also be used. The temperature for heating the raw material is desirably 1,450-1,650 deg.C.

Title: Structure of disk housing in disk player
Inventor: KAWAGUCHI AKIHIRO
IPC: B65D85/57
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To easily take out a desired disk by interposing disks stored in parallel in a longitudinal direction at their lowest point to have them supported at two points at a front and a rear along a diameter and by forming a front support point at a tip of an elastic arm which is always energized upward. SOLUTION: When a disk 1 is inserted into a disk housing from an insertion port 3, a front support point 4 comes into contact with an outer periphery of the disk so that an elastic arm 6 falls counterclockwise against a spring 12. When the lowest point of the disk 1 comes beyond the front support point 4, the elastic arm 6 is restored to an original position, and the disk 1 is supported at two front and rear support points 4, 5 across the lowest point. In this posture, the disk 1 is prevented from rolling out to a front part beyond the front support point 4. The elastic arm 6 including the front support point 4 exhibits cushioning function at the time of putting in/out the disk 6, thereby preventing adverse influence such as deflection to a pickup part.

Filed: 1984-12-11
Abstract: PURPOSE:To reduce a change in sound quality due to a change in a contact condition of a handset and an ear by forming a sound opening for connecting a front surface and a rear surface of a diaphragm of an ear piece unit at an outside periphery of the ear piece part of a housing. CONSTITUTION:At an outside periphery of an ear piece part 2 of a housing 1, a sound opening 5 for connecting acoustically a front surface and a rear surface of a disphragm 4 of a receifing unit 3 is formed. For instance plural sound openings 5 are disposed at the outer periphery of the ear piece 2 of the housing 1, and communicate an inside and an outside of the housing and acoustically connect the front surface of the diaphragm 4 of the receiving unit 3 with the rear surface thereof. Thereby, since a part of a sound wave from the sound opening is leaked through the inside of the housing 1 in case of contacting tightly to the ear, a raise of a sound pressure, in the section of the ear piece part 2 is reduced. Namely since a similar operation to the case when there is a clearance between a handset and the ear is carried out, even if a contact condition with the ear is changed, a change in a acoustic change is reduced.

Title: Method for compensating light load of dc motor variable speed controller
Inventor: MIYASAKA NAOTAKE
IPC: H02P7/292
Filed: 1986-11-06
Abstract: PURPOSE:To be able to compensate a DC motor for a suitable light load irrespective of speed by predicting the interruption starting point of an output current of a thyristor converter from the average value of the output current, and the average value of a firing phase or an output voltage. CONSTITUTION:An armature current control amplifier 3 outputs a deviation between an armature current command I' and an armature current I. A multiplier 12 obtains a product of a motor speed N and a field magnetic flux phi, and applies it to an adder 13. Thus, the output of the amplifier 3 becomes equivalent to that when no induced voltage is generated. The output of the adder 13 is applied through a phase unit 4 to a firing pulse generator 5. A ratio (r) of an interruption starting current obtained by a restriction test to a rated current is set to a setter 7. A comparator 8 operates an armature current control gain compensator 9 when an armature current is the set value (r) or lower. An interruption change corrector 14 varies the set value (r) in response to a firing phase alpha.
