Title: Apparatus for measuring quantity of electric charge of toner
Inventor: UEDA JUNKO
IPC: G01R29/24
Filed: 1990-10-22
Abstract: PURPOSE:To measure a quantity of toner easily and highly accurately by giving a curvature to a support base on which a holder for holding toner is to be mounted. CONSTITUTION:A drum member 2 is placed oppositely to a developing roller 1, and a strip-like dielectric PET film 3 is attached. Then the film 3 with toner 5 attached is separated from the drum 2 and face opposite to one with the toner 5 mounted is adhered to an electrode plate 8 connected to a capacitor 6 and a voltmeter 7. The electrode plate 8 is supported by a support base 10 having insulation performance. Since a curvature is applied to a shape of the electrode plate 8, adhesion between the film 3 and the electrode plate 8 is further enhanced. Then the toner 5 is separated from the film 3. Difference in voltage V between both poles of the capacitor 6 is measured here by the voltmeter 7. Thus a quantity of electric charge Q of the toner 5 is obtained by the measured V and inherent capacitance C of the capacitor 6. A quantity of electric charge of the toner 5 per unit can be obtained by Q/M from the obtained Q and a quantity M of attached toner 5.

Patent JP-H03147218-A (JP)
Title: Switch
Inventor: MIYATA TOMOYOSHI
IPC: H01H21/86
Filed: 1989-11-01
Abstract: PURPOSE:To operate a switch with a small pressing force and prevent the switch from chattering by employing a plate spring so that the spring is supported in a bent condition like a lever with its one end resiliently pressed against the cam portion of a cam lever or against the lower surface of the cam portion and a support shaft. CONSTITUTION:When a lever portion 6 is depressed, the lever portion 6 rotates downward about a support shaft 8. At the same time, a cam portion 7 rotates, the opposite end of a plate spring 10 in press contact with the cam portion 7 comes into contact with a fixed contact point 2, and the fixed contact points 2, 2 are electrically connected to each other. When the pressing on the lever portion 6 is released, the cam portion 7 is pressed up with the spring back force of the plate spring 10 and the opposite end of the plate spring 10 comes off the fixed contact point 2. In this way, a small pressing force on the cam lever 9 or 6 is exerted as a great force on the cam portion 7 about the support shaft 8. Since the plate spring of a relatively great resilient force may be used, switching operation may be performed without the possibility of chattering.

Inventor: TAKAHASHI MITSUTAKA
IPC: H01S5/00
Filed: 1991-10-31
Abstract: PURPOSE:To obtain an optical pickup device which has a semiconductor laser operating with small consumption of electricity. CONSTITUTION:An effective central luminous flux 9 among a luminous flux 7 generated from a semiconductor laser chip 10 penetrates a window glass 6 to a data recording medium 16, whereby the data is recorded and reproduced. Meanwhile, a peripheral luminous flux 12 for monitoring purpose is detected by a detector 11 provided for monitoring purpose in the periphery of the window glass 6. Accordingly, the emitting state of the luminous flux 7 is detected and the amount of electricity to be supplied to the semiconductor laser 10 is controlled so as to make the emitting state constant. Both the effective luminous flux and the monitoring luminous flux can be obtained from one luminous flux emitted from the semiconductor laser and the semiconductor laser consumes less power. Since the consuming power of the semiconductor laser can be reduced and also the consuming power of the optical pickup apparatus can be made small, this invention fully meets downsizing of a compact disk player or the like.
