Title: Semiconductor ic
Inventor: OKUHARA YASUFUMI
IPC: H01L27/08
Filed: 1984-03-28
Abstract: PURPOSE:To contrive the miniaturization of electronic apparatus using the IC and the reduction in cost by a method wherein a latch-up protection circuit made of a Zener diode is incorporated in a semiconductor IC. CONSTITUTION:When a large current drive circuit consisting of a transistor, relay, and the like is connected to the output terminal of the main unit of IC, voltage spike generates in the power source terminal 4 but is weakened by the latch-up protection circuit 8 incorporated in the IC 1, resulting in difficulty of latch-up. Besides, in generation of noise and surge in the source voltage, the influences of these are weakened by the protection circuit 8; accordingly, latch-up can be prevented. This construction is superior in space and cost to the case of outer installation of a latch-up prevention circuit then enabling the attainment of the miniaturization of electronic apparatus using the IC and the reduction in cost. A circuit made by N pieces of series Zener diodes or the series connection of a diode and a Zener diode or a resistor and a transistor can be used for the protection circuit 8.

Title: Image reader
Inventor: OKINO YOSHIHARU
IPC: H01L33/00
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent uneven image density without generating uneven light receiving amount due to flaws, even when light outputted from a light emitting element is almost a collimated light with respect to an image read optical axis in the case that the light emitting element with less generating heat and a high color temperature such as an LED is used for a light source. SOLUTION: In addition to a main light source 66 on an image reading optical axis, a secondary light source 82 with an optical axis tilted by a prescribed angle (30 degrees) with respect to the optical axis of the main light source 66 is provided at upper stream and a downstream of a photo film 22 receiving the light from the mainlight source 66 in its carrying direction. The light from the secondary light source 82 compensates for the scattering of the light of the main light source 66, resulting from the light nearly made collimated to supplement a deficient luminous quantity, so that the light of uniform luminous quantity can be emitted on a required area on the face of the photo film 22.

Title: Broken optical cable detection method
Inventor: SAITO NORIAKI
IPC: H04B3/46
Filed: 1991-03-28
Abstract: PURPOSE:To detect the presence of a broken optical cable in the case of optical communication by the one cable. CONSTITUTION:A signal received by a reception circuit (RX) 14 in the absence of optical input at a receiver side is converted by a serial/parallel conversion circuit 13 and latched by a latch circuit and its output is set to a high or a low prescribed level at a receiver side. A latch circuit 3 at a sender side latches a parallel signal, a parallel/serial conversion circuit 4 converts it and a transmission circuit (TX) outputs the signal to the reception side and the reception output without the optical input in the signal and a data in the opposite level are sent and a line monitor bit is set and the data is sent. Thus, when the optical transmission is implemented normally, the line monitor bit at the receiver side and the output of the optical reception circuit reach a different level and when an optical cable is broken due to any cause, since the line monitor bit and the output of the optical reception circuit reach the same level, then the broken line is detected.

Title: Device for detecting amount of remaining toner
Inventor: SUZUKI MAKOTO
IPC: G03G15/08
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a device for detecting an amount of remaining toner which surely prevents the occurrence of erroneous detection by means of a simple structure. SOLUTION: A distance de between a part of an erect part 57a which is opposite a light emission part 58a and the upper end of a continuous part 57c is set greater than the thickness da of the erect part 57a. Because light from the light emission part 58a repeats reflection inside the erect part 57a and consequently attenuates, an amount of light reaching an erect part 57b via the continuous part 57c decreases and a detecting operation is prevented from being performed erroneously.

IPC: H01M2/02
Filed: 1986-03-24
Abstract: PURPOSE:To reduce the bulging of a container and to increase rigidity by forming the container with a thermoplastic synthetic resin in which a given amount of fine glass fibers is kneaded. CONSTITUTION:A container is formed with a thermoplastic synthetic resin in which 10-20% of fine glass fibers are kneaded.

Title: Noxious insect control applying method for wall surface inner part
Inventor: MIYAZAKI MASAHIRO
IPC: E04B1/72
Filed: 1992-02-04
Abstract: PURPOSE:To prevent the escape of a noxious insect into a wall surface inner part in the case of conducting a noxious insect control by applying a medicine to the wall surface after moving into a building by preliminarily conducting the noxious insect controlling application to the wall surface inner part at the time of constructing the building. CONSTITUTION:In the case of only a noxious insect control by applying a medicine having high immediate effect or delayed effect, noxious insects escape to a wall surface inner part and breed with the lapse of time. Contrary to this, noxious insect control application is preliminarily conducted to the inner part of the wall surface at the time of constructing a building, and the noxious insect control by applying the medicine to the wall surface is conducted as occasion demands after moving in to the building. Thus, this method enhances the effect of noxious insect control and also can contribute to the prevention of spread of noxious insect generation.

Abstract: PURPOSE:To pay change smoothly by employing such constitution that payment is performed by neglecting a continuous payment preventing function by the instruction of an emergency button. CONSTITUTION:A coin is detected by a detection switch 7, and it is counted by a counter circuit 35, and when a counted result shows four, the output of the coin is stopped by a taking out mechanism 33. The continuous-payment preventing function functions before a time-out signal is supplied from a timer 37 even when the detection signal from a detector 15 is supplied, and no payment operation of the coin is performed. In such a case, when the emergency button is depressed before the time-out signal is supplied from the timer 37, it is judged that an emergency request to pay the coin is issued, and a driving circuit 36 is driven, and the coin stocked on a door transiently is paied from a payment port. In other words, every four coins are paid corresponding to the detection of the detector 15 provided in the neighborhood of the payment port, however, the payment is performed by neglecting the continuous payment preventing function by the instruction of the emergency button 26.
