Title: Electrostatic charge image developing toner, developer, developing method and fixing method
Inventor: HIROSE HISAHIRO
IPC: G03G15/20
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain excellent fixing property and high durability without producing offset by controlling the ratio of the weight average mol.wt. to the number average mol.wt. of the resin and the BET specific surface area of the toner to specified ranges. SOLUTION: The ratio of the weight average mol.wt. (Mw) to the number average mol.wt. (Mn) of the resin is specified to 3 to 70, and the BET specific surface area of the toner is controlled to >=5m<2> /g. An average mol.wt. of a material comprising a mixture of molecules of various mol.wts. means the apparent mol.wt. of the material if the material consists of a single kind of molecules. The number average mol.wt. is obtd. by a usual method for measurement of mol.wt., such as a freezing point method. The weight average mol.wt. is obtd. by a light diffusing method or the like. The BET specific surface area of the toner is controlled to >=5m<2> /g, and especially 5 to 40m<2> /g specific surface area is preferable. If the BET specific surface area is less than 5m<2> /g, no effect is obtd.  The specific surface area is preferably <150m<2> /g, and if it exceeds 150m<2> /g, production of the toner is difficult.

Abstract: PURPOSE:To obtain the method of using a ZnSe single crystal thin film formed through MBE as a blue light emission semiconductor device by a method wherein the carrier density of doped Ga is set at a value lower than the value at which a maximum blue light emission intensity is produced. CONSTITUTION:By controlling the temperatures of a substrate 7 and each of the cells 2a-2c of an apparatus through the method for beam epitaxial growth (MBE) and properly opening and closing each of its shutters 4a-4c, a ZnSe monocrystal thin film 11 grows on the GaAs substrate 7. At this time, if the doping of Ga as impurities is carried out by opening the third shutter 4c, the luminance of blue light emitted will change relying on the temperature of the Ga cell and also conform to the carrier density very well. In other words, almost pure blue light emission is available with the carrier density of Ga in the thin film 11 at a value lower than the value which brings the maximum value for blue light emission intensity. The carrier density is set at 3X10<17> or lower.

Title: Floppy disk driving system
Inventor: YUASA MASAHIRO
IPC: G11B21/10
Filed: 1986-04-03
Abstract: PURPOSE:To make return of a head to specified position possible and eliminate a read error by moving a magnetic head in specified direction from present position by a specified distance and returning to original position by moving it in opposite direction by the same distance at the time of resuming after current is cut off. CONSTITUTION:When power supply of a step motor for access 2 is cut off, a magnetic head stops at a regular point of a track of a medium. When resuming power supply, a driving circuit 12 makes a motor 2 step based on control of a microcomputer 15 having a built-in timer, and moves the magnetic head in the outer peripheral direction by 1 track. Then, the motor 2 is made to step in reverse direction, and the magnetic head is moved in the inner peripheral direction by 1 track. At this time, the magnetic head vibrates, and the vibration attenuates gradually, and a position where the head stops finally becomes a position on the regular point of a track at the time of cutting off of power supply. Accordingly, even if the position of the magnetic head is deviated by vibration or a shock when power supply is cut off, the head can be returned to original specified position when power supply is resumed and read error can be eliminated.

Title: Gas hot-water feeder
Inventor: KIMURA YOICHI
IPC: F24H1/10
Filed: 1986-04-02
Abstract: PURPOSE:To enable the feed of a specified amount of hot water at a specified temperature through a simple constitution, by a method wherein, in a gas hot water feeder with a temperature control function, the temperature of water incoming to a heat exchanger is converted into a volume change to detect it, and based on the volume change, a gas control device is controlled. CONSTITUTION:The temperature of water incoming to a heat exchanger 9 is detected by a volume change type temperature detector 13. Namely, when the temperature of incoming water is increased, the volume of a thermoelement 20 is increased to press a spring 25 through a cover 18 and a coupling rod 15, and a pressurizing force on a diaphragm 24 is increased. Thus, the area of an opening between a valve body 23 and a valve seat 22a of a gas control device 22 is decreased to reduce a gas amount. Conversely, during reduction in a water temperature, the above operation is reversed. This constitution enables the feed of a specified amount of hot water at a specified temperature without any electric control part.

CONSTITUTION:When a switch for supplying a paper sheet 57 contained in a cassette 55 is turned ON, a motor 16 on the business machine side is started to reversely rotate the platen 13, and a solenoid 67 is energized to press the separating roller 34 against the paper sheet 57 located at the extreme end position, only one sheet is taken out by rotating the roller 34, and is supplied between the platen 13 and a pinch roller 14, upon which the sheet is maintained in a fixed position. In this case, the lower end of the paper sheet 57 is contacted by the platen 13 and the pinch roller 14, while an upper end part of the sheet is contacted by the separating roller 34, so that the sheet is inhibited from moving backward. When a printing operation is subsequently performed, the sheet is supplied along a paper guide 15 by a forward rotation of the platen 13, and the solenoid 67 is de-energized to separate the roller 34. Accordingly, reliability in supplying a paper sheet can be enhanced.
