IPC: G03G15/043
Filed: 1994-12-21
Abstract: PURPOSE: To reduce the load on a laser part by suppressing laser beam quantity for writing compared to that at the time of regular recording when the rate of the black picture in picture data to be recorded is larger than a reference value. CONSTITUTION: The number of picture data in a whole original and the number of picture data by which beam quantity of LD(laser diode) is suppressed and recording is executed are set in CPU 1. When a printing operation is started, the rate of the black picture in picture data supplied to a printer part is measured. Whether the rate of the black picture is less than the reference value of the black picture rate which is set or not is compared and judged in a black picture comparison means. When it is less than the reference value, CPU 1 controls a laser device 41 so that recording is executed by laser beam quantity at the time of regular recording. When it is larger than the reference value, CPU 1 controls a laser device 11 so that recording is executed by dropping laser power compared to that at the time of regular recording and suppressing laser beam quantity. When all picture data are black, it is possible that the original picture is not correctly read. Thus, a warning message is displayed on a display device 49 and a recording operation is executed.

Title: Hoist with load fall preventing device
Inventor: TANAKA YASUSHI
IPC: B66D5/20
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To impede the fall of a load suspended by a hoist by providing a friction braking means for imparting friction braking force to a driven shaft or a rotating member, constantly rotated along with the driven shaft, whichever direction the driven shaft is rotated. SOLUTION: In the case where a load 8 close to rated load, for instance, a load 8 close to 100kg, is lifted and held in a lifted state, a load of 110kg is needed to release engagement of a friction engaging clutch 9, and a load of 10kg is further needed to rotate a driven shaft 5 against braking force generated by a friction braking means 19. That is, a load sheave 6 is not rotated until a load of 110kg+10kg=120kg acts upon the load sheave 6, Accordingly, as long as a load considerably larger than the rated load is not applied to the load sheave 6, the load sheave 6 is not rotated so as to impede the fall of the load 8.

IPC: B63B1/00
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To improve the presuming accuracy of a flow field around a hull by selecting at least one of four points set up in an actual space on a horizontal plane except a laterally symmetrical plane, and lattice-shapedly dividing a domain inside an actual space set up with the above points.

IPC: G01N27/12
Filed: 1989-12-11
Abstract: PURPOSE:To prevent the generation of misalarm or the misclose of a cutoff valve by sending an output signal and switching a signal transmission interrupting means to the interrupting state only for a fixed period when the change rate of an output signal generated from a gas sensor is a fixed value or more. CONSTITUTION:An insecticide deciding circuit 21 amplifies the output of the gas sensor 5 by an amplifier circuit 22, leads the amplified signal S1 to a differential circuit 23, and when the time change rate of the input signal S1 exceeds a previously determined value, the circuit 23 sends a pulse signal S2. The pulse signal S2 is applied as a driving signal of a timer circuit 24, which sends an output signal S3 for a fixed period from the input of the pulse signal S2. An interrupting circuit 25 interrupts a signal transmitting line from an amplifier/ comparator 6 up to an ON-time checking circuit 7 during the sending period of the output signal S3. Thereby, the generation of misalarm which may be easily generated when a spray gas product is used can be reduced.

Title: Active matrix substrate and its production
Inventor: YOSHINOUCHI ATSUSHI
IPC: G02F1/1368
Filed: 1992-11-27
Abstract: PURPOSE:To provide an active matrix substrate with which the high-mobility characteristics required for TFTs for display and the low-off current characteristics required for TFTs for driving are compatibly obtd. CONSTITUTION:The TFTs (a), (b) for driving are formed by continuously laminating a semiconductor layer 4a and a gate insulating film 5, then patterning the layer and the film to island shapes. The boundaries between the semiconductor layers 4a and the gate insulating films 5 are good and the insulating films 4a are formed to a large film thickness. The TFTs (c) for display are formed by forming the semiconductor layer 4b to a small film thickness and making the resistance of the TFTs higher to decrease off currents and prevent the degradation in the insulation characteristic in the level difference parts of the gate insulating films 3. Further, side wall insulators are formed on the side walls of the gate electrodes 4b and, therefore, these insulators serve as a mask at the time of forming source regions and drain regions. Parts where these impurity ions are implanted or parts 14, 15 where these impurity ions are not implanted are formed among channel parts 20b and the source regions 12b and the drain regions 13b. The off currents at the time of reverse gate bias are thus decreased.
