Patent JP-H10125456-A (JP)
Title: Electromagnetic cooker
Inventor: TAKIMOTO HITOSHI
IPC: H05B6/12
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To restrict the increase of cost of a load detecting circuit, and to enable the detection of load at the time of heating with fine current by comparing an input current detection value with a regenerative current detection value, and detecting a load of an inappropriate load on the basis of a result of the comparison. SOLUTION: At the time of detecting a load of an electromagnetic cooker, an input current detecting signal Vin detected by an input current detecting unit 25 and the regenerative current detecting signal Vinv detected by a regenerative current detecting unit 31 are read by a microcomputer 24. The microcomputer 24 compares the input current detecting signal Vin with the regenerative current detecting signal Vinv, and judges whether a load is appropriate or not on the basis of a result of the comparison. For example, a threshold value is obtained on the basis of the relation between the input current detecting signal Vin and the regenerative current detecting signal Vinv per each load, and in the case where the regenerative current detecting signal Vinv is larger than the threshold value, a load is judged inappropriate, and heating is stopped.  With this structure, a high frequency current transformer for detecting the current of a heating coil and a related adjusting circuit, which are used in a conventional device, are unnecessary.

Abstract: PURPOSE:To obtain a perishable food storage apparatus capable of storing in stable conditions, by constituting the apparatus so as to detect that combustion gas temperature of combustion furnace attains set temperature, communicating a storage cabinet with a combustion furnace and returning O2 concentration of the storage furnace to set temperature. CONSTITUTION:A fuel containing carbon is fired in a combustion furnace 12 and air fed for firing is circulated by an air blower 14 and excess CO2 is adsorbed into adsorbers 22 and 23. Gas atmosphere of the storage cabinet is detected and combustion gas temperature is detected by a detector 48. When O2 concentration of storage becomes higher than set temperature, air route changeover valve 49 is changed over so as to communicate with the changeover valve 49 and the fuel is fired by the air in the furnace 12. When a detector 48 detects that combustion gas temperature attains set temperature, the valve 49 is changed over so as to communicate the storage cabinet 1 with the furnace 12 and O2 concentration of the storage cabinet 1 is returned to set concentration. Since O2 of gas in the storage cabinet is changed to CO2 thus, perishable food can be stored in clean gas without generating harmful gas to the perishable food.

Title: Heater and image forming device
Inventor: OSADA HIKARI
IPC: H05B3/00
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a heater which prevents a fixing defect in the latter half of paper which occurs when using a material having a high heat insulating property for a pressure roller. SOLUTION: When a material having a high heat insulating property is used for a heat insulating layer of the pressure roller, the surface temperature of the roller is lowered during paper passage, and the amount of heat supplied from the pressure roller to paper is reduced to cause a fixing defect. In order to prevent this defect, electric energy supplied to a heater as a heating body is changed synchronously with the rotation period of the pressure roller to compensate reduction of the amount of heat supplied from the pressure roller. This electric energy is determined by the variation of the detection temperature of a thermistor or the variation of power consumption at the time of entrance of paper to a nip part.

Title: Distribution type touch sensor
Inventor: NOMURA AKIHIRO
IPC: G01V8/16
Filed: 1992-09-18
Abstract: PURPOSE:To obtain a distribution type touch sensor outputting accurate shape data and contact pressure data by providing a transparent waveguide having a laser beam source on one side surface thereof and an optical sensor on the opposite side surface thereof and a transparent elastic sheet having an uneven surface. CONSTITUTION:The beam emitted from a laser diode becomes parallel beam 41. A piezoelectric element 5 is driven by the command from a signal processing part 6. The beam 41 is incident on a transparent waveguide 1 at a certain angle on the basis of the driving quantity of the piezoelectric element so as to be totally reflected. When no force is applied to a transparent elastic sheet 3, the uneven surface of the sheet 3 comes into contact with the transparent waveguide 1 at a detection point 8. Therefore, the beam 41 reaches an optical sensor 2 without receiving attenuation. When a force is applied to the elastic sheet 3 having a refractive index larger than that of the transparent waveguide 1, the uneveness of the elastic sheet 3 is collapsed and a close contact part is generated between the elastic sheet 3 and the waveguide 1. As a result, the beam 41 receives the attenuation proportional to the close contact area. This attenuation quantity of beam is detected by the sensor 2 and subjected to signal processing in the signal processing part 6 to calculate the magnitude of the force applied to a force detection point.

Abstract: PURPOSE:To prevent an oscillation transfer plate from being damaged, by providing an oscillator which generates oscillation in an oscillation pen, and a transfer member which transmits the oscillation of the oscillator to the oscillation transfer plate, and forming a contact part at the tip of the transfer member for the oscillation transfer plate with a member provided as a separated body from the transfer member. CONSTITUTION:The oscillator 4 which generates the oscillation in the oscillation pen 3, and the transfer member (horn part 5) which transmits the oscillation of the oscillator 4 to the oscillation transfer plate 8, are provided, and also, the contact part at the tip of the transfer member 5 for the oscillation transfer plate 8 is formed with the member provided as the separated body from the main body of the transfer member 5. Therefore, since the horn part 5 which transmits the oscillation of the oscillation pen 3 has a small coefficient of friction, and it is brought into contact with the transfer plate 8 via a chip part 22 with superior friction resistance, it is possible to prevent the surface of the oscillation transfer plate 8, and also, to prevent the acoustic characteristics (oscillation transfer characteristics) of the horn part 5 from being changed due to friction. In such way, it is possible to prevent the transparency of the oscillation transfer plate 8 from being deteriorated even when the coordinate inputting is performed for a long time, and to prevent coordinate detecting accuracy and detecting resolution from being lowered due to deterioration in the oscillation transfer characteristics.
