Patent JP-H0479606-A (JP)
Title: Filter circuit
Inventor: MIYAKE TOSHIHIDE
IPC: H03H11/12
Filed: 1990-07-23
Abstract: PURPOSE:To obtain a large time constant with a simple circuit configuration by providing two transistors in parallel with each other between a resistance and capacitor and making the sum the output currents of the transistors to flow to the resistance. CONSTITUTION:The emitter area of the 2nd transistor (Tr) Q2 is made (n) times larger than the emitter area of the lst Tr Q1 and the output of the Tr Q2 is fetched from the emitter of the 3rd Tr Q3 of a follower circuit. When an input voltage varies, the resistance-side voltage of a capacitor C varies and, since the base-emitter potential of the Tr Q3 is constant, base voltages of the Trs Q1 and Q2 simultaneously vary. As a result, the voltage applied across a resistance R also varies. Near the center of the operating point of the Tr Q1, the collector currents of the Trs Q1 and Q2 respectively become T1 and nI1 and the total sum of the collector currents of the Trs Q1 and Q2 becomes (n+1).I1. Therefore, a resistance value which is extremely larger than an actual value can be obtained by utilizing the separated flows by means of the two Trs.

Title: Down-load system
Inventor: TANUMA HIROYUKI
IPC: H04L12/44
Filed: 1993-07-09
Abstract: PURPOSE:To reduce the total time required for down-loading the same data on all salve stations. CONSTITUTION:When the same data are down-loaded to all slave stations S1-S10, a master station M sends down-load data to the slave stations S1-S3 connecting to the station M. Each of the slave stations S1-S3 receives the data and stores the data in an internal storage means. Moreover, the slave stations S1, S3 connecting to other slave stations send said received data to the slave stations S4-S6 and S7, S8 connecting to them. Similar processing is made even in the slave stations S4-S8 and down-load processing is proceeded in parallel. Furthermore, when the slave station S10 makes a down-load request to send data received by itself to the slave station S7 connecting to the station S10, the slave station S7 rejects the request because the slave station S7 has already received data down-loaded from the slave station S3.

Title: Semiconductor device and its manufacture
Inventor: KANEKO SHINJI
IPC: H01L29/78
Filed: 1989-07-28
Abstract: PURPOSE:To improve reliability against electrostatic breakdown and hot carrier injection at a gate end-portion, by forming the junction part of an N-type source drain diffusion layer of an N-channel MOSFET, in the manner in which a gate oxide film reaches the center region having an uniform thickness by lateral direction diffusion. CONSTITUTION:A field oxide film 2, a gate oxide film 3 and a gate electrode 4 are formed on a P-type semiconductor substrate 1. The region of the gate oxide film 3 except the part below the gate electrode is turned into a thermal oxidation film 5. The gate oxide film below the gate electrode is divided into a region 6 and a region 7. The film thickness of the region 6 continuously increases by permeation of oxidation species from a gate end-portion. The region 7 has a uniform film thickness. A thermal oxidation film 8 is formed also on the side part of the gate electrode 4. By using a resist pattern, the gate electrode 4 and the thermal oxide film 8 on the side part of the electrode as masks, arsenic is ion-implanted, and annealing is performed in a nitrogen atmosphere. By this heat treatment, an N-type source.drain diffusion layer 9 composed of phosphorus and arsenic is formed. As the result of lateral direction diffusion, the junction part reaches the part below the region 7 where the film thickness of the gate oxide film is uniform.

Title: Electronic tuning receiver
Inventor: MORITA MASAHARU
IPC: H03J7/18
Filed: 1986-08-20
Abstract: PURPOSE:To reduce the cost, to simplify the constitution and to improve the stability by integrating outputs of a voltage controlled oscillating means to directly connect this output to the input of a prescaler and impressing a DC voltage to the voltage controlled oscillating means and the prescaler to switch the reception frequency band with respect to an FM/VHF/UHF electronic tuning receiver. CONSTITUTION:A voltage in the high level is impressed to a voltage controlled oscillating means 3 for FM/VHF/UHF through an FM output terminal. This information is sent to a frequency division ratio calculating means 106 from a reception frequency band switching means 2, and a frequency division ratio N3 corresponding to a desired reception frequency is set. The frequency division ratio is set by this information similarly in case of VHFL, VHFH, and UHF. Consequently, the FM oscillation output is reduced to a half by a prescaler 4 and is supplied to one input of a phase comparator 7 and has the phase compared with the phase of a reference frequency, and an error output  V corresponding to the phase difference is outputted. This error output passes a low pass means 8 to eliminate a high band component, and the output of the means 8 is impressed to a varactor diode 63. When the output  V is zero, PLL is locked to receive the desired frequency.

Abstract: PROBLEM TO BE SOLVED: To eliminate the output of unrequired commands and to accelerate a printing processing by providing a selection branches so as not to output the pertinent command in the selection branches of a settable item. SOLUTION: An operation mode setting part 3 is for setting the operation mode of a printer 4, is activated by a user before performing printing in the printer 4 and performs setting suitable for a printing matter. For the display contents 31 of 'change of setting of printing direction' displayed at a non- entered display part by the operation mode setting part 3, in the example, 'do not output command' is set. In this case, the need of outputting a unidirectional printing specifying command or a unidirectional printing release command is eliminated. Also, for the display contents 32 of 'change of setting of signal slip system command', in the example, 'do not output command' is set. In this case, since the need of outputting the command relating to upper end margin specification, paper feed and discharge is eliminated, the printing processing is accelerated.

Title: Pump device
Inventor: NAKAYOSHI HIDEKI
IPC: F04C15/06
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To eliminate air bubble produced in a valve downstream side passage of a reflux passage by installing an extension chamber, having a sectional area being larger than this valve downstream side passage, in space between the valve downstream side passage and an inlet port. SOLUTION: Oil to be discharged at a high speed to a valve downstream side passage 41 from a discharge port 9 for exhausting of a exhaust control valve 2 produces a cavitation, thereby causing an air bubble in itself. Since the center of an inlet passage 3 is almost accorded with a jet flow direction, pressure goes up more than the upstream side at the more downstream side than the inlet passage 3 of the valve downstream side passage 41, so that the air bubble dwindles away to nothing. The oil contained with some bubbles left behind at the valve downstream side passage 41 as too substantial for removal, passes through a reflux passage 4 and then passing an extension chamber 7. Here, since this extension chamber 7 is larger in a passage area than the valve downstream side passage 41, a flow velocity of the oil contained with bubbles slows down in the extension chamber 7.  With this constitution, the pressure goes up further, and thus the air bubbles disappear.

If a memory unit 2 is not set or is in an incomplete set state, the circuit 31 of the female connector 29 is not connected to the male connector 30, and the output of the inverter 27 goes to the low level, and the logical condition is not established in an AND gate 29, and a pulse signal is not outputted to an oscillator on/off control circuit 20, and reading is not performed. Consequently, unnecessary read operation and battery consumption are prevented.

About 50% waste glass aggregate can be used and on the other hand new aggregate and new asphalt are not needed. The >=50% waste glass aggregate is necessary to be mixed and when there is an anxiety about peeling, a peeling preventing agent can be added into an after mixer 12 by a peeling preventing agent adding device 13 to be mixed and stirred.
