Title: Bending method of pipe
Inventor: UEDA SHINICHI
IPC: B21D7/025
Filed: 1979-03-24
Abstract: PURPOSE: To prevent the deformation of pipe section which occurs at the bending of pipe by applying rotation-tensile-bending work by the use of a rotary bending die of the shape that the caliber flange parts overhang to more than the radius of the work pipe.  
     CONSTITUTION: The work pipe 5 is clamped in a rotating bending die 2 by the clamping die 9 on a rotary table 3 and a core metal 6 is inserted into the pipe 5. When the back of the pipe 5 is held by a holding die 10 and the rotary bending die 2 is revolved, the pipe 5 is tensile-bent according to the movement of the bending die 2. The caliber 2 1  of this bending die 2 is formed to the depth which restrains the buckled protruding parts perpendicular to the bending plate which occurs at the bending of the pipe 5. More specifically, the caliber 2 1  is made to the depth determined by protruding the caliber flange parts 2 2  to more than the radius r if the radius of the pipe 5 is let r. The use of such bending die 2 enables the sectional deformation of the pipe 5 to be prevented.

Title: Channel sensor of television receiver
Inventor: SAEKI YOSHIBUMI
IPC: H04N17/00
Filed: 1979-03-23
Abstract: PURPOSE: To make it possible to decide a channel of current receiving by detecting the leak signal of a local oscillator and by measuring the frequency of this leak signal.  
     CONSTITUTION: When television receiver 3 is operated, local oscillator 22 oscillates to receive a specific channel, and the high frequency wave of the frequency corresponding to that of the channel is transferred to MIX circuit 16 to convert the frequency to an intermediate frequency. Since the high frequency wave oscillated by local oscillator 22 leaks, the leak signal can be caught by coil 23. This caught signal is amplified by amplifier 24 and has the frequency reduced by frequency divider 25 and is sent to gate circuit 26. Counter 28 counts the frequency of the leak signal and sends the count value to code converter 29. The code converter converts the decimal value to a binary value. This converted signal is sent to center 4 through cable 7.

Abstract: PURPOSE:To prevent the over-supply of a toner by supplying the electrostatically charged toner of a porality in accordance with the polarity of a direct current bias from a toner supplying roller to a developing roller. CONSTITUTION:One side of a terminal of a direct current power source 18 is connected to a sleeve 16, and from this direct current power source 18, a voltage V1 for example, the direct current bias of -1,000V is impressed to the sleeve 16.

Title: Release agent coating apparatus
Inventor: SHIMONISHI KOJI
IPC: B29C33/58
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent a deterioration of an environment of a working place due to scattering of an excess release agent to a circumference by providing a cover near a coating nozzle in the case of coating a surface of a synthetic resin mold with the agent from the nozzle. SOLUTION: A cylindrical cover 3 made of a transparent acrylic resin is mounted at coating guns 21, 22. A brush 31 is mounted on an overall periphery of an end opening of the over 3. Coating airless guns 21, 22 move along a mold surface in X-and Y-axis directions, spray release agents from coating nozzles 211, 221 to simultaneously efficiently coat the mold surface with the agents. In this case, since the cover 3 is provided, the agents are limited to a coating range by a cover, and hence not scattered to the circumference. And, since a brush 31 is provided at an end of the cover 3, the excess coated agent is scraped by bringing the brush 31 into contact with the mold surface coated with the agent or coats an insufficiently coating position, thereby reducing a coating unevenness.

Title: Ignition timing control device
Inventor: DAIMON TERUMI
IPC: F02P5/152
Filed: 1982-03-10
Abstract: PURPOSE:To prevent a miss operation by biasing a knock sensor signal input section with a predetermined voltage and by providing a time delay to the output section of a comparator detecting the input voltage change when the sensor and its connection section are short-circuited or open-circuited. CONSTITUTION:A knock sensor is biased with a constant current circuit I1 consisting of TrT1, R2, R3 to generate a sensor terminal voltage VKS, when it is short-circuited VKS<0.2V, the output of a comparator CO2 is made L, when it is open-circuited VKS>3.6V, the output of a comparator CO1 is made L, thus making TrT2, T3 off and on which are normally on and off respectively with both outputs of CO2, CO1 being H, thereby the control output voltage of a knock signal voltage conversion circuit KSV is increased, and the ignition time is delayed so as to prevent the knock from occurring. Since the comparator happens to generate an L output due to increased engine vibrations at high speed rotations, a time delay is provided by use of an integrating circuit consisting of R7-R9, C1, thus a miss operation can be prevented without deteriorating the primary fail-safe function.

Abstract: PURPOSE:To decrease the coupling capacity of a capacitor and to facilitate circuit integration by amplifying a difference between an AC component of an output of a current-voltage conversion section and a reference voltage, comparing the result and decoding an output after waveform shaping into a binary digital signal. CONSTITUTION:A current-voltage conversion section 1 converts a current obtained from a photodetector into a voltage and a 1st differential amplifier section 3 amplifies a difference between an AC component of an output from the conversion section 1 and a reference voltage generated from a reference voltage generating section 2.

Title: Manufacture for carbonaceous negative electrode material for nonaqueous electrolyte secondary battery
Inventor: KIHIRA TORU
IPC: H01M10/0525
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To provide negative electrode material to which high capacity characteristics or excellent cycle characteristics can be given by applying in gas atmosphere an electron beam accelerated under high vacuum to carbonaceous material capable of doping light metal ion and removing its dope. SOLUTION: Irradiation of an electron beam is not performed under high vacuum, but is performed under nitrogen or algon atmosphere with normal temperature and normal pressure. Thereby, reducing pressure in irradiation atmosphere is not required, and a lead time for manufacturing can be shortened substantially, so that productivity can be enhanced. Not more than 300ppm of oxygen density in gas atmosphere is preferable. Graphite or cabon material which is difficult to make graphitic is preferable for an object to which the electron beam is applied. It is preferred to use graphite with characteristics that a ratio of a peak area at 1530cm<-1> to a peak area at 1580cm<-1> in a Raman spectrum increases by irradiation of the electron beam.
