Title: Electronic device containing mechanism part
Inventor: MACHIDA MINORU
IPC: G06F15/02
Filed: 1984-03-23
Abstract: PURPOSE:To prevent a fault and breakage to be produced at a mechanism part of a printer, etc. by cutting off the power supply to the mechanism part when a fault like a jam, etc. of the mechanism part is detected by a control part. CONSTITUTION:When a motor ON signal which drives a motor of a printer 2 has a rise through a control part 1, the motor is driven by a motor driver DRMT. At the same time, the printer 2 transmits a print timing signal to the part 1 via a receiver RCVT. If a paper jam, etc. is produced, the print timing signal becomes irregular. This irregular signal is compared with a pattern of a normal mode to detect a fault at the side of the printer 2. Then a control line CONT is changed to a low level according to the fault detect at the printer 2. Then the power supply is cut off from the printer 2.

Title: Paper sheet carrying device with automatic restoration function
Inventor: HAMA YOSHIHITO
IPC: G07D9/00
Filed: 1990-03-06
Abstract: PURPOSE:To improve the operation rate of the paper sheet carrying device by detaching an restorable area after a reset operation from a carrying processing object and executing the carrying processing by only other active carrying system. CONSTITUTION:When a CPU 31 detects a fact that abnormality of an apparatus is generated on carrying paths L1 - L11, the CPU 31 allows the equipment to execute a reset operation, based thereon, and executes a restoration processing of a carrying system. When it is decided to be unreleasable after the reset operation, the CPU 31 detaches only its restorable apparatus from a carrying processing object, and executes a carrying processing by utilizing effectively other carrying system. In such a way, even if an restorable area is generated in the carrying system, the operation of other carrying system is maintained, and the device is operated without allowing it to go down, therefore, the operation rate of the device is improved surely.

Title: Driving method of charge transfer image pickup device
Inventor: HORII SAKAKI
IPC: H04N5/335
Filed: 1984-03-23
Abstract: PURPOSE:To prevent the generation of flicker by transferring an electric charge of the 1st vertical transfer electrode group and an electric charge of the 2nd vertical transfer electrode group and mixing the charges so as to form them into a unit picture element signal charge. CONSTITUTION:Since the electric charge stored in a photoelectric conversion storage diode 1 is transferred to transfer electrodes phiV2, phiV4 of a vertical charge transfer register 9, the highest voltage is applied. The electrode of the highest level is applied with the phiV2 and with the phiV4 after a prescribed time. Then the phiV2 and the phiV4 are applied with a prescribed time difference so as to transfer the stored charge of the diode 1 to the register 9. The two charges are mixed after that and the result is outputted sequentially. On the other hand, the electrodes phiV1, phiV3 are closed when the stored charge of the diode 1 is transferred to the phiV2 and phiV4 to prevent flicker due to the leakage of the charge caused by capacitor coupling.

Title: Lens barrel
Inventor: SENDA AKIRA
IPC: G02B7/02
Filed: 1988-03-07
Abstract: PURPOSE:To prevent the occurrence of cloud-up of a lens in a barrel by providing devices generating dry gas containing no moisture, injecting the dry gas generated by the devices into the barrel and keeping its hollow full of said gas. CONSTITUTION:In case the dry gas filling the barrel 1 leaks outside due to its poor airtightness, the barrel is full of the dry gas by injecting it from the dry gas generating devices 2 and 3 constantly. Since the inner pressure of the barrel is kept higher than outer pressure, the invasion of air containing moisture into the barrel from a poor airtightness part can be prevented. As a result, the barrel 1 is constantly full of dry gas containing no moisture, that is, a humidity of almost 0 deg.. Cloud-up in the barrel thereby never occurs even if external temperature changes suddenly.

Title: Ink jet recorder
Inventor: MIYAGAWA AKIRA
IPC: B41J2/01
Filed: 1981-04-14
Abstract: PURPOSE:To provide a titled device which can eliminate the influence due to a difference in a back pressure even when a discharge frequency increases, by a method wherein an ink jet head is designed to incline toward a main scanning direction with the increase in a subscanning line density and a discharge frequency. CONSTITUTION:An ink jet head 1, wherein a plural number of recording elements are aligned in a subscanning direction (a vertical direction in a drawing), is inclined in a main scanning direction in case a subscanning density changes to increase a discharge frequency, and this reduces a difference in a back pressure generated in each recording element. An operation to incline the head 1 is performed by driving a servo-motor M via a signal line by means of a signal controlled through detection of the discharge frequency. Based on the rotary angle of the head 1 corresponding to the subscanning line density detected by a position and rotary angle detector of a carriage, a discharge timing is delayed by a time equivalent to a lag time determined by the pitch of each recording element to correct a shear in printing.
