Title: Developing device
Inventor: MIYASAKA TORU
IPC: G03G15/08
Filed: 1994-03-07
Abstract: PURPOSE:To obtain a high-speed one-component developing system with high stability by arranging a blade, a roller, etc., for making the layer of toner thin on the surface of a thin film cylindrical member, and a guiding member stabilizing the thin film cylindrical member on a photoreceptor side with respect to a driving roll. CONSTITUTION:The toner in a toner reservoir is rubbed on the surface of a developer carrier 6 composed of a thin film member wound on the driving roll 4, to form a charged toner layer. The toner layer formed on the developer carrier 6 driven by the rotation of the driving roll 4 is more charged by the friction with a regulating blade 3 pressurized by a spring 2 and the thickness of the toner layer is regulated to obtain a stable electrostatic charge quantity and layer thickness. The thin layer of the toner is carried to a photoreceptor 1 as a latent image carrier by the rotation of the driving roll 4. The stable contact of the developer carrier 6 with the photoreceptor 1 is kept by a guiding member 7. Thus, the stably charged developer thin layer is formed and stable contact pressure can be obtained.

Title: Arm driving circuit
Inventor: MAEDA TETSUO
IPC: G11B21/12
Filed: 1982-03-05
Abstract: PURPOSE:To always maintain the offset error angle at 0 deg. and prevent noises, by setting a reference voltage source in such a way that, when the offset error  angle of an arm is 0 deg., the output of a photointerruptor becomes equal to the  voltage of the reference voltage source. CONSTITUTION:When a stop switch 13 is depressed to bring up an arm 4a from a gramophone record, a switching circuit 11 is switched to the 2nd reference voltage source 8, whose voltage is higher than that of the 1st reference voltage source 6, through a logical operation circuit 12. When the switching circuit 11 is switched, control which makes the output of the photointerruptor 5 equal to the voltage of the 2nd reference voltage source 8 takes place and a motor 1 forces an arm base 4 to move to the inner periphery side of the gramophone record. The output of the photointerruptor 5 must coincide with the voltage of the 1st reference voltage source 6 in the course where the output approaches the voltage of the 2nd reference voltage source 8 and passes through a point where the offset error angle accurately becomes 0 deg., and thus, the arm 4a starts operation.

Title: Charging method for secondary battery
Inventor: KIZU MASANOBU
IPC: H01M10/44
Filed: 1991-02-04
Abstract: PURPOSE:To realize appropriate charge control, regardless of charging conditions such as the magnitude of charging current or ambient temperature, by detecting a timing when secondary differentiated value of a charging voltage curve makes a transition from positive to negative and utilizing thus detected timing in charge control. CONSTITUTION:Battery voltage (a) increases relatively slowly upto the intermediate stage of charging operation but a turning point C exists, in any case, between the intermediate and final charging stages. An interval during which variation rate of battery voltage varies from substantial zero to a maximum negative value immediately after the turning point C substantially matches with full charge timing. Consequently, the turning point C can be detected based on transition of the secondary differentiated curve (c) of the battery voltage curve from positive to negative value. Full charge time can be determined by detecting at least one of points A and B at which a curve (b) representing the following variation of battery makes a transition from positive to negative or takes a minimum value, respectively.

Title: Method for controlling air conditioner
Inventor: YAMASHITA TETSUJI
IPC: F25B5/02
Filed: 1994-03-07
Abstract: PURPOSE:To prevent a dew from being generated on a surface of a radiation type heat exchanger in an air conditioning system having a convection flow type heat exchanger and a radiation type heat exchanger by a method wherein indoor temperature and humidity at a starting time of cooling operation are divided into a plurality of temperature and humidity zones in advance and a dehumidifying control is preferentially performed when a temperature and humidity detected value at the starting time is within a high humidity zone. CONSTITUTION:A convection flow type heat exchanger 1 and a radiation panel 4 acting as a radiation type heat exchanger are commonly used in an indoor device, and at the time of starting operation, the indoor area is divided into a high humidity zone having a relative high humidity and a low humidity zone having a low humidity. In the case that an operation starting temperature and humidity are placed within the high humidity zone and controlled toward each of temperature and humidity set values, a less temperature difference may occur against a dew point temperature due to the fact that there occurs a high humidity at the operation starting temperature or humidity and the surface of the radiation panel 4 is kept at a state where a dew formation may easily be produced. At an area where the number of rotation of a fan shows a low number of rotation, there are much amount of dehumidifying operation even under a low number of rotation of a compressor and an indoor temperature is decreased. As the number of rotation of an indoor fan and the number of rotation of the compressor are increased, the indoor temperature is decreased, so that the preferential dehumidifying operation is carried out under an operation performed from a high humidity zone.
