Title: Image forming device
Inventor: YAMAMOTO KAZUMA
IPC: G03G21/00
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent the soiling of a transfer roller by toner in a state between paper sheets without lowering throughput by changing the duty of developing voltage between the continuous paper sheets. SOLUTION: When an engine controller receives a printing instruction from a host, a photoreceptor drum is driven to be rotated first and electrification is made on. Next, a laser is turned on in timing when a position where negative charge is applied by the electrification comes to a laser irradiating position, and development is made on at a position where the laser is turned on. When the toner applied by the development comes to a transfer position, recording paper is precedently fed so that the recording paper comes to the transfer position. In such a case, the duty is changed at the specified rate only between the paper sheets. Then, duty control is switched in the same manner as in the case of adjusting density with PWM output in the engine controller. Thus, an excellent image without soiling a back surface is obtained.

Title: Proximity sensor
Inventor: SAITO MASAHIRO
IPC: G01V3/10
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction when a DC is applied to detect, for example, the passage of a pinball game ball by constituting an LC oscillation circuit by a coil and a capacitor that are wound around a pot core using a metal dust core. SOLUTION: An LC oscillation circuit is composed of an air-core coil 4 that is wound around a pot core 3 whose one part is opened and a capacitor, and a sendust dust core is used for the pot core 3. As for the B-H characteristics of a sendust core, a magnetic flux density gradually increases for a magnetization force, and cannot be saturated even with a magnetization force of, for example, 100 oersted.  The change in inductance when a DC magnetic field is applied is approximately 1/2 as compared with that of ferrite core due to the influence of absence of a core in the case of the sendust dust core, but does not decrease rapidly to the DC magnetic field, and Q characteristic is slightly smaller than that of the ferrite core, thus preventing malfunction due to, for example, the application of DC magnetic field since the effect for preventing the transmission stop due to the DC magnetic field is great.
