IPC: G06F3/03
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To maintain the light emitting performance of a light source and to stabilize performance as an optical coordinate inputting/detecting device. SOLUTION: A translucent cover 11 for preventing dust from accumulating on a light emitting surface 10 directly is provided on the front surfaces of the surface 10 of plural LEDs 1 and 3 constituting a light emitting means of an optical coordinate inputting/detecting means. Thus, dust, etc., is prevented from accumulating on the light emitting surfaces directly while it is used for a long time. Also, because the dust, etc., can be eliminated by cleaning the cover 11, the light emitting surfaces of the light emitting elements are prevented from being damaged by cleaning. Further, the light emitting elements can be protected from an unforeseen accident by providing the cover on the front surface of the light emitting surfaces of a light emitting means.

Title: Drive circuit for field effect transistor
Inventor: NISHIZAWA YUJI
IPC: H03K17/687
Filed: 1985-04-12
Abstract: PURPOSE:To prevent generation of surge by connecting a buffer capacitor between a gate and a drain of an MOSFET driving an inductive load so as to soften the switching operation and to decrease the delay time. CONSTITUTION:When a switch SW1 is turned on and a switch SW2 is turned off, a gate-(G)-source-(S) voltage VGS rises toward a voltage V1 in a time constant decided by a resistor R1 and a stray capacitance CGS, and when the voltage reaches a threshold voltage VTH, the voltage VHS is in the resident state because of the effect by the capacitance CGS and the buffer capacitor C0. Thus, the rate of rise of a drain current ID and the rate of fall of a drain- source voltage VDS are decreased attended therewith and a recovery current IR is decreased. Then the voltage VGS keeps the resident state due to the increase in the internal capacitance of the FET and then the voltage VGS rises up to the voltage V1. In operating conversely and switches SW1, SW2, the opera tion is made converse and the resident state of the voltage VGS is kept longer by the effect of the buffer capacitor C0 also in this case. Thus, the rate of change in the ID and VDS is decreased and the generation of a surge voltage at the drive of the inductive load 3 is prevented.

IPC: B65H1/12
Filed: 1994-03-25
Abstract: PURPOSE:To reduce the number of inspection times for parts of a device and save labor required for setting paper by providing a press releasing means which releases a press of a paper feed roller against the receiving tray side and separates a lid body from the paper feed roller in an action, interlocking with the movement of the lid body when it is opened. CONSTITUTION:Since a recording paper receiving tray 3 is normally pushed upward by a spring 5, the recording paper receiving tray 3 and a paper feed roller 4 are brought into pressure contact with each other when recording paper is not set. In setting recording paper, an operator holds up the top end of a document receiving tray 2. This makes the document receiving tray 2 rotate, thus opening the top part of a device case body 1. When the document receiving tray 2 rotates, the projected part 2b of the document receiving tray 2 is brought into contact with the cut-projecting part 3b of the recording paper receiving tray 3, pushing the recording paper receiving tray 3 downward. As a result, the pressure contact between the paper feed roller 4 and the recording paper receiving tray 3 is released and both of them are separated from each other. In this condition, the operator inserts multi-piled recording paper 13 onto the recording paper receiving tray 3, and closes the document receiving tray 2. The inserted recording paper 13 is locked at the position of a claw 6.
