Title: Magnetic shield structure of magnetic sensor
Inventor: SHIMIZU SHINJI
IPC: G01R33/06
Filed: 1990-11-02
Abstract: PURPOSE:To obtain a highly efficient shield structure by setting up the first shield stuff of permalloy manufacture covering a part of a magnetic sensor and the second shield stuff of electromagnetic soft iron manufacture surrounding this shield stuff and covering the remaining part of the magnetic sensor. CONSTITUTION:First, extraneous magnetic fluxes 20 are hard to break through the inner space of a case 1 and a magnetic sensor provided within the case 1 does not receive the influence of the outside magnetic field because the magnetic fluxes 20 pass through the insides of a cover 2 of electromagnetic soft iron manufacture and a shield plate 3 of permalloy manufacture when the extraneous magnetic field is applied. Next, the cover 2 of electromagnetic soft iron manufacture is magnetized by the residual magnetization because it is not of low coercive force and the magnetism generated by this breaks through inside and outside the case 1 when this outside magnetic field is removed. However, the magnetic fluxes to flow the inside of the case 1 flow the inside of this plate 3, do not break through to the inside space of the case 1, and do not affect the magnetic sensor because the plate 3 is inside the case 1.

Title: Portable wireless transmitter
Inventor: KUMAGAI TAKASHI
IPC: H04B1/034
Filed: 1987-11-26
Abstract: PURPOSE:To attain both the simplicity of operation in generating an emergency signal and the elimination of mis-operation by providing a grip operation switch and a pullout operation switch to a wireless oscillator main body and transmitting the emergency signal when both the switches are in operation. CONSTITUTION:When a security signal such as an emergency signal is sent from the wireless oscillator 1, at first the grip operation switch 2 around the oscillator is gripped by a hand as a 1st step. Then a minute current flows between conductive electrodes through the hand and the current is sensed to complete the 1st step. In a 2nd step, the pullout pin 3a of the pullout switch 3 is pulled out to interrupt the continuity between jacks 3b, 3c, but since the pin 3 is connected to a neck cord 8 in this operation, it is implemented easily by pulling the main body 1 downward by the hand gripping the switch 2 as shown in figure. Thus, the emergency signal is sent but if any of them is operated in mistake, no emergent signal is sent. Thus, the transmission of the emergency signal due to mis-operation is prevented.

Title: Interlock for electric dust collector
Inventor: YASUMURA NAOKI
IPC: B03C3/68
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To save time and labor for key management by providing a high voltage transformer-rectifier assembly for applying a DC high voltage to the main body of equipment after receiving outputs from a change-over switch, an interlock code set circuit and a thyristor. SOLUTION: If a code is input by a person entering the main body of an equipment to an interlock code set circuit (I) 9, then I9 sends the interlock signal to a change-over switch 7. By this signal, the change-over switch 7 is turned off. Next, if the person comes out of the main body of equipment and enters the same code to I9, then the I9 outputs an interlock reset signal. By this signal, the change-over switch 7 is turned on and sends a control signal from a charge control circuit 8 to a thyristor 6. The thyristor 6 outputs AC corresponding to this signal. A high voltage transformer-rectifier 2 receives this AC and outputs a DC high voltage and applies it to the main body. As a result, conventional keys are no more necessary and thus the labor and time for key control can be saved.

IPC: B41J29/00
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To alleviate a complexity of operability by inhibiting setting of a cover or lamination mode in the case of different sheet sizes of a sheet supply tray of a master unit set as a cover or lamination special purpose tray and a sheet supply tray of another image forming apparatus as a slave unit. SOLUTION: An image processor having a CPU 68 checks the presence or absence of each sheet supply tray as cover special purpose trays, a sheet size and the presence or absence of a sheet for both an own unit and a slave unit. If the tray set as the cover tray is not present at least in one of the own unit and the slave unit, if the sizes of the trays are different or if no sheet is in the tray, setting of a cover mode is inhibited. Thus, a complexity of operability generated caused by an association with a coupling mode, a cover mode or a lamination mode can be alleviated and a miscopy caused by an erroneous operation can be suppressed.
