Title: Driving circuit for semiconductor laser
Inventor: HIRAKATA NOBUYUKI
IPC: H01S5/042
Filed: 1988-07-07
Abstract: PURPOSE:To seek to prevent relaxing oscillation by connecting a resistor to the cathode side of a semiconductor laser, and connecting a capacitor in parallel with the series circuit of this resistance and the semiconductor laser. CONSTITUTION:A point different from a conventional circuit is that a resistor R is connected in series to the cathode side of a semiconductor laser LD, and a capacitor C is connected in parallel with the series circuit of this semiconductor laser LD and the resistor R. Hereupon, as the resistor R, one above 1 - several ohms and below 100 ohms is selected, and also as the capacitor, one above 0.1pF and below 10pF is selected. Hereby, the high frequency components of currents that flow to the semiconductor laser are cut, and even when it is driven by a rectangular wave, the oscillation of light emitting output is prevented, and it becomes possible to remove relaxing oscillation peculiar to the semiconductor laser.

Title: Film unit with lens
Inventor: KAWAMURA FUMINORI
IPC: G03C3/00
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To eliminate the trouble that the part of a unit which is the most projecting to the front is rubbed and worn out by packing material during transportation degrading the commercial value by providing a switching member with a switching knob having a specified shape. SOLUTION: The switching knob 33c is formed at the lower part of the switching member and projects forward from a slit formed on an external cover. Therefore, the switching member is moved in a lateral direction by operating the knob 33c. In this film unit with a lens, the top of the knob 33c is the most projecting forward in the entire unit. Then, a rise part 54 extended in a width direction is provided at the center part in the length direction of the knob 33c, and a flat part 54a is formed on the top surface of the rise part 54 and the width of the flat part 54a is at least 0.5 mm. By forming the flat part 54a, the wear of the top of the knob 33c is prevented.

Title: Facsimile equipment
Inventor: AOKI YUTAKA
IPC: H04N1/04
Filed: 1990-06-27
Abstract: PURPOSE:To prevent an original from being automatically sent to stations other than an object station of the user by masking a mark output when a position of the mark attached to a designated region is coincident with a position of a black stripe. CONSTITUTION:A black stripe discrimination region 37 (blank part) is provided to an identification sheet 30 just before a designated region 34, and black picture information and its position on a specific line of the black stripe discrimination region 37 are stored and when the position of the designated region 34 is actually the position of a black stripe 36, a mark output is masked. As a result, since the black stripe 36 is masked when the black stripe 36 is just coincident with the designated region with an abbreviation number designated thereon, a telephone line is correctly connected to the designated abbreviation number. Thus, when the black stripe 36 is overlapped on the designated region 34 representing a mark column, the transmission of an original to stations other than an object station of the user is avoided.

This stock is put into the mold and while the stock is remelted and pressurized, the one side thereof is cooled and the other side is heated to apply the temp. gradient in the direction perpendicular to the orientation of the reinforcing fibers, by which the stock is slowly cooled and solidified. The fiber reinforced metallic material 2 provided with the crystals 5 grown in the direction perpendicular to the direction of the reinforcing fibers in the metal 3 solidified in the reinforcing fibers 4 subjected to the above-mentioned paralleling is thus obtd. The above-mentioned material 2 is thereby easily improved in the strength in both the longitudinal and transverse directions.

Title: Service isolate control device of elevator
Inventor: HIROTA MASARU
IPC: B66B1/14
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To simply isolate service to a specified floor by operating a floor display plate of destination floor buttons installed in an in-car operation board to conduct an isolating function for normal service, and judging on whether it is a service floor or not from the existence/absence of the plate. SOLUTION: When a car is stopped at the first floor, an owner in the third floor living room calls the car to the third floor by a hall call register button of the third floor elevator hall to get on the car. The floor display plate of the third floor destination button installed in the in-car operation board is taken out to isolate the service to the third floor by the destination floor button. In such a condition, the third floor destination button indication is removed in the in-car operation board, whereby it is seen that the operation by the destination button to the third floor is disabled. On the other hand, when the function is recovered, the taken-out floor display plate is put back to the operation board so that the operation by the destination button to the third floor is enabled.

Title: Dynamic semiconductor memory device
Inventor: HARA TAKEHIKO
IPC: G11C11/407
Filed: 1989-06-30
Abstract: PURPOSE:To reduce stress for the memory cell transistor of a maximum power supply potential and to improve reliability by comparing the second potential with the power supply potential, outputting a control signal when the second potential is higher and reducing the potential of an output terminal. CONSTITUTION:To a first potential Vpp 1 to be boosted in proportion to a power supply potential Vcc, a second potential Vpp 2 lower than this first potential by a fixed value is acquired by a level shift circuit 2. A comparator circuit 3 compares the second potential Vpp 2 with the power supply potential Vcc and when the second potential Vpp 2 is higher, the control signal is outputted. A discharging circuit 4 in an output terminal WKM in a boosting circuit 1 is controlled by the control signal from the comparator circuit 3 and the potential of the output terminal WKM is forcively reduced. Accordingly, when the boosting ratio of a word line is determined so that '1' reading defect can not occur in the minimum potential, the potential of the word line is suppressed with a value for which a prescribed value is added to the power supply potential. Thus, the potential of the word line in the maximum potential is made low and the reliability of an oxide film is secured.

Title: Tape device
Inventor: IIDA TADASATO
IPC: G11B15/70
Filed: 1979-12-26
Abstract: PURPOSE: To detect assuredly the sag of a tape and stop the travelling of the tape, by providing a sensor consisting of a light emitting element and photodetector obliquely to the tape facing of the wall substance which control the range of sag of the tape rolled out by a capstan.  
     CONSTITUTION: When the tape travels in the normal condition, the tape 11 rolled out between the capstan 16 and the pinch roller 17 is taken up smoothly around the circumference of the wound tape via the guides 14 and 15. Under these conditions, the light given from the light emitting element 25 is detected by the photodetector 26 to deliver the normal state detecting signal. In case a smooth winding is impossible for the tape, the tape 11 touches the surface of the wall substance 19. Thus the light from the element 25 is cut off, and accordingly the detecting signal is delivered from the photodetector 26 for occurrence of a sag of the tape. Based on this detecting signal, a protective action such as the stoppage of driving or the like is given.
