Title: Paper feed controller
Inventor: KANETANI KOICHI
IPC: B65H7/04
Filed: 1985-06-04
Abstract: PURPOSE:To control paper feed by judging a near paper end according to the number of the succeeding encoder pulses. CONSTITUTION:The number of transfer papers actually fed is adapted to correspond to the number of encoder pulses produced then so that how many numbers of pulses for paper types mounted on a tray at present show the paper end can be for-cast. And when 20 sheets of transfer paper are fed, a variable receiving the pulse number produced from the encoder 11 is assumed ENDCNTR. When the pulse number produced in the ascent of the tray from the lower limit to the upper one is assumed 1000 and the encoder pulse becomes larger than the value of 1000-ENDCNRT, the transfer is stopper assuming that the number of the residual sheets are reduced less the 20 sheets.

Title: Image forming device
Inventor: TAKEDA MASAMI
IPC: G03G15/20
Filed: 1995-05-18
Abstract: PURPOSE: To provide an image forming device capable of taking measures to deal with the wrinkling of a fixing envelope without impairing fixability and without requiring a complicated mechanism even if a fixing speed is increased. CONSTITUTION: This image forming device has the fixing means for fixing the toner image onto a transfer material by application of heat and pressure thereon and is constituted by using a system to set the reference position for transportation of the transfer material as the reference for one side end of either left or right as the fixing means. The pressurizing force for fixing on the reference side (envelope passing side) of the fixing means is reduced and the heat generation distribution in the longitudinal direction of the heater (heating element) 4' of the fixing means is so set that the calorific value on the reference side is higher than the calorific value on the non- reference side.  The fixing pressure on the reference side of the fixing means is reduced according thereto and, therefore, the occurrence of the wrinkling of the fixing envelope with an increase in the fixing speed is prevented. The degradation in the fixability according to the deficiency of the pressurizing force for fixing on the reference side is made up by increasing the calorific value of the heater (one side light distribution intensification heater) 4' on the reference side.

Title: Communication right control system for isdn terminal
Inventor: KAWASHIMA MASAHIRO
IPC: H04L12/40
Filed: 1991-05-24
Abstract: PURPOSE:To attain an automatic incoming state even at a terminal where a power supply is not applied yet by shifting the communication right to another terminal from a specific one when a communicatable state is secured with application of the power supply of another terminal corresponding to a subaddress after the specific terminal detects an incoming state and decides the subaddress. CONSTITUTION:A communication right control system contains a master terminal 13 which is connected to a DSU 11 via a bus 12 and plural slave terminals 14. The terminal 13 shifts to a communication state in response to the call setting signal received from a network. Then the terminal 13 analyzes a subaddress, controls the application of the power supply of terminals 14, and transmits an interruption signals to the network in a workable state. Each of terminals 14 analyzes an E bit received from the DSU 11. If this analyzing result shows an interruption signal sent from the terminal 13, a call restart signal is transmitted with use of a call number equal to that designated in the interruption signal. Thus a terminal 14 shifts to a communication state in place of the terminal 13.

IPC: H04N5/335
Filed: 1992-04-13
Abstract: PURPOSE:To shorten the time required for defect detection by judging the pres ence of any defect at a certain address when a fixed value or a value higher than it exists in a map obtained by an operation processing. CONSTITUTION:A white flaw is detected by calculating whether the signal levels of respective addresses in a frame memory (a) are higher than a reference value for white flaw detection or not, and the white flaw bit map showing the distribution is prepared in a frame memory B. Next, a black flaw is detected by calculating whether the signal levels of respective addresses in the frame memory (a) are lower than a reference value for black flaw detection, and a black flaw bit map showing the existent positions is prepared in the frame memory B. Then, '1' is weighted to the white flaw, and '2' is weighted to the black flaw (or '0' is weighted to no flaw.) Afterwards, the map is prepared by multiplying a spatial filter in a defective pattern pairing the white flaw and the black flaw to be detected to a synthetic map showing the existent positions both of the white flaw and the black flaw, and the defect of the pattern is calculated by calculating the address which value is fixed.

CONSTITUTION:A cover 10, arranged so as to be opposed to a van guard 8 with a space between the upper surface of the fan guard 8, is larger than the area of projection of the upper surface of the fan guard and one end of the metallic sheet thereof is fixed to the back surface of an outer casing while the other end of the same contacts a bead 9 provided on the back surface of the fan guard 8. Oil, is supplied from an oil feeding tank 4 by inverting the tank 4 after clamping the cap 4a of an oil feeding port, however, the cap 4a falls off or oil in the tank 4 is scattered onto the upper surface of the outer casing some times when the tank is pulled out of the outer casing 1 if the cap 4a is not closed perfectly. Part of the scattered oil flows to the back surface of the outer casing 1 and drips to the outside of the fan guard 8 along the cover 10. Accordingly, the oil will never flow into the part of a fan through a slit hole 8a, therefore, flaming of the oil will never be caused.

Abstract: PURPOSE:To early discover an improper registration of a mask film by forming a photodiscoloring coating film on a photosensitive liquidlike solder resist film and discoloring it by exposure so as to eliminate a delay of discovering of defects such as misregistration of a mask film due to no confirmation of a finishing state after exposure since photosensitive liquidlike solder resist does not generally contain a photodiscoloring component in order to obtain its characteristics and stable composition. CONSTITUTION:A printed circuit board 1 is coated with a photosensitive liquidlike solder resist, and dried to obtain a photosensitive solder resist film 2. Then the film 2 is coated with photodiscoloring ink, and dried to form a photodiscoloring coating film 3. Further, a mask film 4 having a predetermined pattern is superposed on the board 1, registered, and exposed thereby to obtain anexposed solder resist film 6 and photodiscolored coating film 5.

Title: Lithography apparatus
Inventor: IWAMATSU SEIICHI
IPC: H01L21/30
Filed: 1979-09-21
Abstract: PURPOSE:To permit a lithography apparatus to be more compact by placing a mask and a mirror between an object to be exposed and a ray source, and swinging the mirror to perform lithography. CONSTITUTION:The X-ray radiated from an electron orbit 1 of a synchrotron are emitted from a ray source having a directivity of an angle theta, and applied through a mask 2 to a wafer 3. In this case, an X-ray reflecting mirror 4 is placed near the ray source, and swinged vertically or in the direction of theta1. This permits the X-rays to perform a scan or step-scan within the range of the stripe-shaped mask. Allowing the mirror 4 to totally reflect by making the incidence angle small permits an Au evaporated mirror to obtain a reflection power close to 100% for soft X-rays of the order of 100Angstrom  or more. This permits the distance between the ray source and the object to be exposed to be less than half. Consequently, the apparatus can be more compact.

Title: Fuel cell
Inventor: SEGAWA NOBORU
IPC: H01M8/02
Filed: 1984-06-14
Abstract: PURPOSE:To steadily maintain cell performance for a long time by dividing an electrolyte layer into two layers having different electrolyte-retaining capability. CONSTITUTION:Two layers, each of which is about 100mum thick, of electrolyte matrix made of silicon carbide having uniform particle size are formed by varying fluorine resin content. Fluorine resin content of the matrix layer in contact with a fuel electrode is limited to about 10W/O to SiC, and that of the matrix layer in contact with an oxidizing agent electrode is about 3W/O. When a specified amount of acidic electrolyte is impregnated, the electrolyte is impregnated in the matrix through the layer having less fluorine resin content. Bubbling pressure of the electrolyte matrix shows 680-760mm.Hg. This value is the same as that of a uniform component electrolyte matrix layer whose fluorine resin content is 10W/O and thickness is 200mum.
