Title: Electron emission element and its manufacture
Inventor: SATO TOSHIFUMI
IPC: H01J9/02
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To provide an electron emission element made of diamond particles, having a thermally and chemically stable surface and having a high electron emission rate. SOLUTION: An electron emission element has an emitter portion formed of diamond particles, comprises an electron supply source 13 and an electron emitting portion 14, and supplies electrons to the electron emitting portion from the electron supply source 13 including a defective structure, thus making possible formation of an emitter which can stably and efficiently emit electrons. The electron emission element is placed on an anode substrate comprising a transparent electrode and a phosphor thin film on its opposite side to a cathode, and when a predetermined voltage is applied between the cathode and anode, electrons are emitted from the electron emitting surface layer of the electron emitter portion into a vacuum, and the electrons accelerated reach the phosphor thin film and collide against the phosphor thin film, causing the phosphor thin film to fluoresce.  Thereby a field emission type display can be constructed.

Title: Private branch exchange
Inventor: IZUMI SHINYA
IPC: H04Q3/58
Filed: 1990-04-05
Abstract: PURPOSE:To reduce a load on a caller by performing such control that an automatic re-dialing means is started up and a dial signal held at a dial signal holding part is automatically sent by re-capturing a line wire in a state where another line wire is busy. CONSTITUTION:When line wire outgoing is performed by an operating (DISA) function of direct call and internal function of an extension from the line wire based on a command from an outside caller 109, a system is comprised so that the dial signal issued to the line wire 110 can be stored in a dial holding part 107. When the line wire 110 is busy, a control part 108 starts an automatic redialing operation, and re-captures the line wire periodically, and automatically sends out the dial signal held at the dial holding part 107 to the line wire. Therefore, when a re-call is performed to the line wire 110, dial signal data with respect to outgoing performed previously remains in an exchange, therefore, the automatic re-dial operation can be performed based on the data, which dispenses with the re-dial signal sending operation of the caller 109. In such a way, it is possible to reduce the load on the caller.

Abstract: PURPOSE: To expell the scraped developer immediately from a developing roller and prevent the developing roller from degrading by capturing and conveying the one- component type developer scraped from the developing roller and returning the same to the upper part of a developer vessel.  
     CONSTITUTION: The insulating toner scraped from a developing roller 1 by an elastic scraper 3 is gathered in the central direction of the developer roller 1 by a screw 4 and is further conveyed to the upper part of a hopper 11 by a screw 5. It is then mixed in the toner in the hopper in a region 9. The screw 4 is cut with grooves 4a of opposite directions with the center as a boundary. In the case of a magnetic toner, the toner scraped from the magnet sleeve 1' by the scraper 3 is captured by a magnet roll 6 and the toner is conveyed to the upper part of the hopper 11 by the magnetic force between the roll 6 and an opposing magnetic roller 7 rotating at the same speed, thus it is mixed into the toner in the hopper in the region 9. Eaves 10 prevent a conveying path 12 from being exerted with the pressure of the toner in the hopper.

Title: Radio transmitting and receiving device
Inventor: MATSUKURA MASAYUKI
IPC: H04B1/40
Filed: 1984-05-08
Abstract: PURPOSE:To reduce the current consumption of a power switch circuit without decreasing the operating time by connecting a switching element in parallel with a power control switch inserted between a radio transmitting/receiving section and a power battery and turning on/off the switching element with a control circuit. CONSTITUTION:A contact of a relay 6 is connected in parallel with a power operating switch 5. An output of an AND circuit 10 is used as a drive signal of the relay 6, an output of the 2nd timing circuit 9 is inputted to the radio transmitting/receiving section 3 to turn on/off the output of a transmitter. Since the relay contact is closed by turning on a press switch 2 in this way, the transmission current flows to a power supply operating switch 5 and the relay contact. Moreover, the reception current flows to the power operating switch 5 only at the stand-by state. In other words, a large current at transmission flows to the relay and a minute current at the stand-by and reception flows to the power operating switch 5 such as a toggle switch, then a miniature switch is used for the power switch 5.

IPC: F02D41/16
Filed: 1987-04-13
Abstract: PURPOSE:To control the revolving speed of engine reasonably while matching with the response characteristic varying with warming of engine gradually by changing and setting the non-sensitive zone width at the time of feedback control according to the engine temp. CONSTITUTION:When a control device 12, at the time of starting, judges from output signal of a water temp. sensor 17 that the engine 1 is cold, the target idling speed according to this engine temp. is set together with the non-sensitive zone width in the idling speed feedback control. When it is judged that the difference of the current revolving speed of engine from the target idling speed is below the lower limit of the set non-sensitive zone width, a valve opening signal is given to ISCV9, followed by increase of the air flow from an aux. air passage 8 in bypass connection over throttle valves 4a, 4b, so as to put the revolving speed of engine within the set non-sensitive zone width. The idling speed can be controlled reasonably by narrowing the non-sensitive zone width with change in the response characteristic of engine 1 caused by rise of the engine temp.

IPC: G01N23/223
Filed: 1990-04-05
Abstract: PURPOSE:To collect fluorescence X rays only from the outermost surface of a sample and to perform highly sensitive measurement by emitting the X rays into the sample through the transmitting hole of an X-ray detector, and detecting the radiated fluorescence X rays. CONSTITUTION:This apparatus comprises an X-ray detector 4 having a hole 4' which passes X rays 3. A sample 5 is arranged on the passing path of the X rays 3 in the vicinity before and after the X-ray passing side of the hole 4'. The X rays 5 are made to pass through the sample 5. The fluorescence X rays generated from the surface are measured with the detector 4. The change in absorption due to the change in material due to the X rays is measured. Since the X rays pass through the hole 4', the fluorescence X rays generated from the surface of the sample can be efficiently collected by a large amount. Thus, the highly sensitive measurement of a minute structure for absorbing the expanded X rays can be efficiently measured in a short time.

Title: Cigarette lighter
Inventor: SUZUKI MASARU

Filed: 1982-05-29
Abstract: PURPOSE:To obtain a cigarette lighter which is compact, inexpensive and durable, by utilizing a shape memorizing alloy metal as a thermal responsive material which functions to detect a heating condition of a heater element. CONSTITUTION:When a reverse martensite change is caused to take place by heating up of a heater element 16 and subsequently of a contacting resillent member 30, the contacting resilient member 30 shows its inherent property of resuming a memorized shape. As the contacting resilient member 30 is memorized a shape that a spring shows in a fully elongated state, that is, it stores a length of elongation which realizes a relation Wo<WL+W'1 where W'1 is a compression load, and therefore a plug section is disengaged from a retention and then pushed backwardly to a normal position. In consequence, the heater element 16 is deenergized. Under such a state, the plug section 1 is withdrawn from a socket section 21 for igniting a cigarette. In this case, a compression load of a return spring 7 is indicated as WL, and a retaining force of an earth ring 10 in engagement with a convexed portion 32 as Wo.
