Title: Copying machine
Inventor: YAMASHITA TOSHIYUKI
IPC: G03G21/00
Filed: 1988-08-31
Abstract: PURPOSE:To prevent the generation of copying error resulting from an error in action by making the machine so that when a paper feeding cassette is loaded in a paper feeding opening before a printing key is inputted in an APS mode setting, the APS mode is released and a manual mode is set. CONSTITUTION:If the paper feeding cassette is loaded in an upper paper feeding opening 17 or a lower paper feeding opening 18, and in addition when an upper cassette non-loading flag or a lower cassette non-loading flag is 1, if the mode is APS (Automatic Paper Select) mode, the mode is made manual. Therefore, in the APS mode setting, since the mode is changed to the manual mode when the paper feeding cassette is loaded before the printing key is inputted, copying is carried out on a copying paper of the desired size by the user. Thus the generation of copying error resulting from the error of the user's action can be prevented.

Title: Line control apparatus
Inventor: TAMADA SHINICHI
IPC: H04L69/40
Filed: 1990-08-21
Abstract: PURPOSE:To carry out efficient debug and failure analysis by analyzing the content of bus, followed by converting the content into significant codes, further followed by serially numbering the codes, furthermore followed by serially storing the codes for each line address, and finally followed by reading out the stored content whenever line failure occurs. CONSTITUTION:Every time a line control appartatus 2 reads and writes data, an address decode circuit 5 decodes address, a data analysis circuit 6 converts the address into significant codes and serially numbers the codes, and a memory control circuit 8 writes the codes in a memory 4 corresponding to the line address. Thus, until the data analysis circuit 6 detects line failure, the memory control circuit 8 cyclically carries out overwriting for each line. Further, immediately when a line failure such as receiving trouble, and sending trouble is detected, the memory control circuit 8 stops writing. By reading the content of memory 4 outside via an output control circuit 7, line failure is easily analyzed.

IPC: G05D23/19
Filed: 1984-10-19
Abstract: PURPOSE:To improve the operability and the safety of a temperature controller containing a timer by performing the temperature control based on the output of a temperature detecting element as soon as the actuation of a timer is started with push of a switch and increasing the clock frequency of the timer in case the temperature detecting element has a disconnection. CONSTITUTION:When a start switch 21 is pushed, a latch device 22 latches the start signal to start the actuation of a shift register 26. At the same time, a temperature controller 24 can be actuated. then the controller 24 turns on and off a heater to control temperatures by means of the output of a temperature detecting element 23 consisting of a thermistor. The working state of the register 26 is displayed by a light emitting display element 27 to show the time passed. The register 26 resets itself in this setting mode and also resets the device 22 to complete a timer action. The clock frequency is increased by a frequency increasing device 29 when a disconnection of the element 23 is detected by a disconnection detector 28. Thus the actuation of the register 26 is accelerated to end the timer action quickly. In this case, a fault if any an be known by the movement of a display element 27.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a compact light shielding blade for an optical machine whose the light shielding property is high regardless of being less in a manufacturing man-hour and being inexpensive. SOLUTION: A substrate 1 of a light shielding blade for an optical machine 3 is constituted of an elastic material such as a synthetic resin. Both the surfaces of the substrate 1 are coated with coating materials 2a and 2b obtained by mixing a phenolic synthetic resin, carbon black for shielding light and graphite for enhancing lubricity, for example. At this point, since the larger amount of the material 2a is used for coating in comparison with the material 2b, the blade 3 is warped to the side coated with the material 2a due to the difference in contractibility when the coating materials are dried. When the plural sheets of blades 3 manufactured in such a way are combined so that the surfaces coated with the material 2 are mutually faces, they can be used as the light shielding blade for an optical machine whose light shielding property is high.

Title: Method of crystallizing semiconductor thin film
Inventor: SAMEJIMA TOSHIYUKI
IPC: H01L21/20
Filed: 1990-08-22
Abstract: PURPOSE:To obtain, with good reproducibility, a semiconductor thin film whose electric characteristic is good and which has been crystallized reliably by a method wherein the distribution of an irradiation laser energy density is set to be stepwise and specific in a stepwise scanning direction. CONSTITUTION:A semiconductor thin film is formed on a substrate 11 ; the thin film 1 is irradiated with a pulse laser 2; and the thin film 1 is crystallized by a melting method. When the thin film 1 is irradiated with the laser 2, e.g. a zigzag scanning operation is executed by a scanning operation in the x- direction and a stepwise scanning operation in the y-direction. The energy density of a beam spot S regarding individual beam spots b1 to b5 is increased gradually in the x-direction from the front of the x-direction toward the central part when individual transmission distributions of filters F1 to F5 are selected properly. Thereby, a stepwise or mountain-shaped distribution in which the energy density is lowered gradually toward the rear is obtained. Thereby, when a volatile substance exists in the thin film 1, the thin film is crystallized so as to be a more excellent film quality because its sudden volatilization can be changed to a gentle volatilization.
