Title: Image forming device
Inventor: NAKAO MASAHIKO
IPC: G03G15/00
Filed: 1989-08-30
Abstract: PURPOSE:To prevent image forming failure, etc., caused by the bending of a sheet, failure in correcting obliquely feeding paper, leading edge timing failure and paper feeding failure with a resist roller by making a paper deflection quantity in front of the resist roller nearly equal in either a double-sided copying mode or a synthetic copying mode. CONSTITUTION:According to a double-sided image forming mode or a synthetic image forming mode, a selecting means 95 selects either a first timer 94a or a second timer 94b. By this selection, the length of time from the detection of a sheet P by a resist switch 65 to the carriage of the sheet P by a paper re-feeding part 6 in an image forming mode is made different from one in the synthetic image forming mode. Thus, the carrying quantity of the sheet P, namely, the paper deflection quantity in front of the resist roller, after the resist switch 65 detects the sheet P, is made nearly equal in either mode. Thereby, image forming failure caused by the bending of the sheet P, failure in correcting the slantly feeding paper, leading edge timing failure and paper feeding failure by the resist roller, etc., are prevented.

IPC: B23Q15/00
Filed: 1986-09-22
Abstract: PURPOSE:To reduce the occurring probability of input mistakes by applying a touch input method for programs through a CRT screen. CONSTITUTION:When a touch is given to a prescribed position of a display screen where a touch sensor 3 is set, a touch sensor control part 2 decides the coordinates on the screen. Then a main CPU 4 decides the information on said coordinates as prescribed based on a program included in a memory 1. The CPU 4 carries out each processing in response to a part having a finger touch. Thus an operator can have input of program commands of the working order and the tool shift based on the drawing of a working object, etc., with use of the graphics most suited to the input after recognizing visually many types of picture information at a time in comparison with a key operation method where similar keys are arranged in a small space.

Abstract: PURPOSE: To quickly lower a temperature in a freezing chamber after it is defrosted and hence prevent an advance influence to an article stored in the freezing chamber by forcedly changing over cooling operation only for the freezing chamber only for a predetermined time after completion of defrosting operation for a condenser. CONSTITUTION: A defrosting heater 7 is interrupted in power supply thereto, and defrosting operation is completed, and further a timer 35 starts 30 minute timer operation to output a high level signal, and the high level signal is applied to driver circuit 22, 29 through OR circuits 21, 28. Hence electric, power is impressed to a solenoid valve 13 and a compressor 6 irrespective of the states of a refrigeration chamber temperature control section 15 and a freezing chamber temperature control section 23, and hence the operation is forcedly changed over to the state where a refrigerant discharged from the compressor 6 is supplied only to a freezing chamber condenser 4, and hereby cooling operation only for the freezing chamber 2 is achieved.  When 30 minutes are elapsed since such cooling operation is started, a low level signal is outputted from the timer 35, and thereafter ordinary cooling operation is achieved with the refrigeration chamber temperature control section 15 and the freezing chamber temperature control section 23.
