Title: Original reader
Inventor: TSUNEKAWA MAKOTO
IPC: H04N1/19
Filed: 1989-01-13
Abstract: PURPOSE:To prevent the useless consumption of energy by operating a received light quantity detection circuit only when an original is read and scanned and executing dummy scan until a read signal is made stable during a fixed scanning period just after the received light quantity detection circuit is operated. CONSTITUTION:A received light quantity detection circuit SC is operated only while a detection circuit driving pulse is outputted. During the period from the end of original reading and scanning to the start of the next original reading and scanning, the operation of the circuit is stopped. A read signal (g) detected by the received light quantity detection circuit SC is made ineffective by a read signal sending control means 25 during the initial scan, in which the read signal (g) is instable, and the read signa is not sent to a read signal inputting device Me. Then, after the read signal (g) is made stable, it is set to the read signal inputting device Me. Thus, the useless consumption of the energy can be prevented.

IPC: G03G15/01
Filed: 1990-01-17
Abstract: PURPOSE:To prevent a contrast potential from lowering even when colors are superposed and to prevent toner scattering from occurring at the time of exposure by constituting a device so that the surface potential of an electrostatic latent image forming member after it passes a 1st electrostatic charging means may be made higher than that after it passes a 2nd electrostatic charging means. CONSTITUTION:A control means for controlling the polarity and the electrostatic charging quantity of a coloring electrostatic charging particle on the electrostatic latent image forming member 13 and and a transfer means are arranged in this order with respect to the moving direction of the member 13. Then, this device is constituted so that the surface potential of the member 13 after it passes the 1st electrostatic charger 1 may be higher than that after it passes the 2nd electrostatic charger 2. With such constitution, a photosensitive body where the toner is carried is electrostatically charged once before exposing an image equal to or above the electrostatic charging potential of the photosensitive body necessary for development, and destaticized to the electrostatic charging potential of the photosensitive body so as to invert the polarity of the toner on the photosensitive body. Thus, the lowering of the contrast potential in the case of superposing the colors is eliminated and the toner scattering at the time of exposure is prevented.

Title: Plating method for lead frame of semiconductor device
Inventor: OKAMOTO AKIHIRO
IPC: C25D5/08
Filed: 1991-01-25
Abstract: PURPOSE:To prevent plating leakage into the rear side by installing a suction and exhaust air hole for preventing lead frame deformation to a specified position on a stopper rubber board on the rear side and evacuating air after the application of pressure sealing. CONSTITUTION:A lead frame 7 is pressure-sealed by a plating area mask board 6 on the rear side and a stopper rubber board 5 on the rear side. Then, an exhaust air compressor installed to a plating device is operated so that a plating solution may be ejected so as to carry out plating under such a condition which allows the exhaust air in a suction and exhaust air hole 4 to be still evacuated. An exhaust air valve of the compressor is opened so that the air may flow into the suction and exhaust hole 4 once again. This construction makes it possible to cancel the suction of the lead frame. This is not limited to a single in-line package lead frame and it is also applicable to lead frames whose shape is often subjected to the generation of plating leakage on the rear side.

Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent a metal diaphragm from being melting, and perform a long-term stable ink drop injection by a method wherein the diaphragm is electrically connected with a GND electrode formed on a substrate. SOLUTION: When a driving voltage pulse Vp is applied between the edge face electrodes 22 and 23 of piezoelectric element 12 for driving an ink jet head, a minute induced current flows in the diaphragm. Under the condition that the diaphragm 31 bonded to the topmost layer of the piezoelectric elements 12 is made of a metal material, the diaphragm 31 serves as a kinds of electrode material, which is electrically connected with the piezoelectric elements 12 through a capacitive coupling, causing to induce a voltage by means of a driving voltage pulse.  By earthing the diaphragm through the electrical connection with a GND electrode, the current induced in the diaphragm flows to the earth, resulting in preventing the elution of the metal ion of the diaphragm in the ink due to the induced voltage from developing or the melting of the diaphragm so as to make a hole therein from developing. Accordingly, the long term reliability of the diaphragm is improved and a stable printing quality can be ensured.
