Patent JP-H03153121-A (JP)
Title: Level conversion circuit
Inventor: WAKAYAMA YASUSHI
IPC: H03K5/02
Filed: 1989-11-09
Abstract: PURPOSE:To quicken the fall time at a signal output terminal without increasing power consumption by adding a 3rd N-channel MOS transistor(TR) whose gate electrode is connected to the output of an inverter circuit and the inverter circuit whose input is connected to a signal input terminal to a conventional circuit. CONSTITUTION:The high voltage level of a signal output terminal 9 goes to the voltage level of a positive power supply 7 and the low voltage level goes to a value obtained by dividing a positive powre supply voltage by inter-channel impedance of a 2nd P-channel MOS TR 8, a 1st N-channel MOS TR 3 and a 2nd N-channel MOS TR 6. When the level at a signal output terminal 9 is descended, since the 1st N-channel MOS TR 3 and the 3rd N-channel MOS TR 10 are both turned on for a delay time of the inverter circuit 4, the change time is quickened by increasing the drive capability of both the TRs and even when a current of a constant power supply comprising a reference voltage input terminal 5 and the MOS TR 6 is not increased, the fall change time is quickened.

Title: Phase locked loop circuit
Inventor: NISHIKAWA MAKOTO
IPC: H03L7/107
Filed: 1990-10-29
Abstract: PURPOSE:To reduce the time for phase synchronization establishment and to establish the synchronization of the phase locked loop by providing a loop changeover circuit selecting a loop circuit system having a low pass filter only with a control signal at phase asynchronization. CONSTITUTION:When a phase of a frequency division signal S2 of a frequency divider 2 and a phase of an output signal S3 of a reference signal generator 3 are not synchronized, an output signal S4 of a phase comparator passes through a low pass filter 5 only and when the phase synchronization establishment is detected by a switching control circuit 8 is detected, the signal passes through the low pass filter 5 and a loop filter 6 to control a voltage controlled oscillator 1. Thus, the low pass filter 5, the loop changeover device 9 and the switching control circuit 8 are provided to select the combination of the low pass filter 5 and the loop filter 6 with the loop changeover device 9 thereby preventing phase synchronization unestablishment due to leakage of a reference signal without delaying the establishment time of phase synchronization even when the phase comparison frequency is low.

Title: Bipolar transistor for building-in in integrated circuit device
Inventor: SHIMIZU MASASHI
IPC: H01L21/8222
Filed: 1988-11-18
Abstract: PURPOSE:To enhance utility efficiency of carrier and to improve current amplification factor by burying first and second semiconductor layers between first and second epitaxial layers, and diffusing connecting layers for connecting to the semiconductor layers from the surface of the second layer. CONSTITUTION:First and second epitaxial layers 4, 10 are sequentially grown on a substrate 1, first and second semiconductor layers 6, 7 are buried between the layers 4 and 10, and the layers 6, 7 are connected to external connection electrode film 40 through connecting layers 12 diffused from the surface of the layer 10. Thus, a position to cross the surface of semiconductor of a junction between a base and an emitter is limited only to the periphery of the connecting layer, this part is isolated from the active regions of the base layers 4, 10 for enhancing the current amplification factor, and the length is of only the peripheral length of a connecting layer 13 to be reduced. Thus, the probability of the carrier being erased by recombination on the surface of the semiconductor of this junction is almost eliminated. Thus, the injection efficiency of the carrier to the base layer is enhanced, and the current amplification factor can be improved.

Title: Reforming catalyst temperature controller in fuel cell power generating device
Inventor: YAMAMOTO OSAMU
IPC: H01M8/06
Filed: 1986-12-08
Abstract: PURPOSE:To control a temperature of a reforming catalyst by mean of only combustion of an off gas by installing a temperature controller to control a load connected with a fuel cell and installing a regulator to regulate an air-fuel ratio of the off gas to combustion air. CONSTITUTION:A fuel reformer 1 is supplied with liquid fuel by a pump 13 and with combustion air by a blower 9, and its combustion is performed by a burner 2 so that a temperature of the reforming catalyst is raised. When a temperature of the catalyst rises up to an activation temperature, a reforming raw material is supplied to a fuel reformer 1 by a pump 32 so that a reforming gas is generated. This reforming gas and the air are supplied to a fuel cell, and so power is generated to be supplied to a load 37. When a sufficient amount of an off gas is started to be supplied to the reformer 1, the supplying of the liquid fuel is stopped and combustion of only the off gas is performed. The temperature of the reforming catalyst 4 is detected by a temperature detector 6, and the load 37 is controlled by an output signal of the temperature controller 20, and so power generation of the cell begins to make a fixed amount of load current flow across the load 37. Besides, when the blower 9 is controlled by an output signal of an air-fuel ratio regulator 23, the amount of the combustion air is regulated.

Title: Electrophotographic printing plate
Inventor: SATO YOSHIHIRO
IPC: B41C1/10
Filed: 1990-10-30
Abstract: PURPOSE:To improve the sensitivity in a visible and near infrared range by a method wherein a photosensitive layer obtained by dispersing a phthalocyanine compound, a perinone compound, and a compound selected out of a group composed of a guanidine compound and a guanamine compound in an alkali- soluble resin is provided on a conductive substrate. CONSTITUTION:In an electrophotographic printing plate, a photosensitive layer obtained by dispersing a phthalocyanine compound, a perinone compound, and a compound selected out of a group composed of a guanidine compound and a guanamine compound in an alkali-soluble resin is provided on a conductive substrate. The thickness of the photosensitive layer is preferably 1-20mum. If the thickness is less than 1mum the surface electric potential of the photosensitive body is lowered, and only a small amount of toner is applied to an image part when the toner is developed. Thus, such a toner-free part as a pin hole is generated. If the thickness of the photosensitive layer is more than 20mum. a long time is required for dissolving and removing a non-image part of the photosensitive body by an alkali aqueous solution and, furthermore, the photosensitive layer of an image part, such as thin lines and fine dots, is easily removed by side etching.

Title: Tube fitting device
Inventor: YASUDA MASAHARU
IPC: F16L25/00
Filed: 1988-11-21
Abstract: PURPOSE:To maintain a sealing function as well as to make any external leakage of fluid in a joint unit preventable by adding a form memory alloyed sleeve which varies its form at more than the specified temperature for contraction, making contact with both joint outer surfaces and produces the sealing function. CONSTITUTION:At a temperature of less than the specified one, a sealing function like in the past is securable by a form memory alloyed sleeve 6 and rubber seals 3a, 3b. Next, when the temperature becomes more than the specified one, another form memory alloyed sleeve 7 is contacted, further compressing these rubber seals 3a, 3b, thereby enhancing the sealing function yet higher. Simultaneously the sleeve 6 comes into contact with each outer side of flanges 7a, 8a of both sleeves 7, 8, joining two joints 1, 2 together firmly for sealing, thus any leakage of an internal fluid is preventable. Accordingly, if such a case that these rubber seals 3a, 3b has lost the sealing function by burning due to a temperature rise in case of a fire or the like, the internal fluid is prevented from occurring owing to the sealing function by the form memory alloyed sleeve 6.

Title: Driving/controlling method for thermal head
Inventor: YANAGISAWA JUICHI
IPC: B41J2/355
Filed: 1995-11-10
Abstract: PURPOSE: To propose a method for driving/controlling a thermal head properly at all times without being influenced by the temperature of an ambience, a heating state of the thermal head, etc. CONSTITUTION: When a tape-printing apparatus is driven to print, an initial temperature T1 immediately after a power source is turned ON and a temperature T2 immediately before the printing are detected, and further a temperature T3 (i) of an ambience of a thermal head is detected every printing time. When a difference of the initial temperature T1 and the temperature T2 is small, the temperature T2 immediately before the printing is employed as the ambience temperature to control the time while the electricity is supplied to the thermal head. If the difference is large, the initial temperature T1 is employed as the ambience temperature thereby to reduce the feed time of electricity to the thermal head. If the temperature T3 (i) is increased with a large rate during the printing, the temperature T2 is adopted as the ambience temperature to reduce the feeding time. In the case where the temperature is raised to a temperature indicative of an overheating state during the printing, the thermal head is stopped.

Title: Magnetic disk
Inventor: YURA SHINSUKE
IPC: G11B5/64
Filed: 1987-11-20
Abstract: PURPOSE:To lower the coefft. of friction between a head slider and medium and to prevent attraction while assuring the floating extent of the head slider by providing projections in an island shape on a magnetic recording medium layer or protective layer and forming a protective layer on the island-shaped projections. CONSTITUTION:Al is stuck to the island shape 7 on the magnetic recording medium 3. The protective layer 4 is further stuck thereof by sputtering and a lubricating film 5 is applied thereon. The so-called CSS (contact start stop) system in which the head slider is in contact with a disk during the stoppage of rotation and floats while sliding with the disk surface upon starting of rotation is adopted. Since the island-shaped projections 7 decrease the true contact area at the time when the head slider 6 comes into contact with the medium, the coefft. of friction decreases and the attraction is substantially prevented. The protective layer 4 formed on the island-shaped projections securely fixes the island-shaped projections and prevents the exfoliation thereof.
