Title: Chuck and rotary working device using the same
Inventor: TANAKA SHINJI
IPC: B23Q17/24
Filed: 1992-03-02
Abstract: PURPOSE:To perform precise misalignment correction with a workpiece being kept attached to a chuck and highly precise working of fine mechanical elements, by using a piezoelectric element with respect to a chuck portion for retaining the workpiece. CONSTITUTION:The rotating state of a workpiece 6 is observed, from the direction of a rotary shaft of a spindle 3, with use of a microscrope 12 and a TV camera 13, and the observed state is displayed on a monitor 14. Subsequently, it is decided, using this picture image information, whether or not the center of rotation of the workpiece 6 is in coincidence with that of the spindle 3. The voltages applied to piezoelectric elements 1-1, 1-3 are applied, from a power source 9, using a joy stick 10, and a displacement is imparted while observing a monitor 14. After a center of the workpiece 6 is set to a sesired position, the workpiece 6 is worked using a turning tool 11. The observation during the working operation is made using the same microscope 12 and the TV camera 13.

Title: Thin type high load burner
Inventor: KIKUTANI FUMITAKA
IPC: F23D14/02
Filed: 1986-02-28
Abstract: PURPOSE:To shorten the length of flame and realize a high-load combustion by making zigzag flame bands along air openings arranged in a continuous channel shape provided on a side air injection plate and a center air injection plate to increase an area contacting with secondary air. CONSTITUTION:A part of secondary air passes through a clearance formed by a small projection 11 and is reduced in pressure, thus reaching a flame holding air chamber 12 through flame holding air ports 13 and being ejected into a combustion chamber 1 through both sides of the burner port portion as a secondary air flow of a low speed. Accordingly, the flame is first stabilized at its base portion by the flame holding air, and thereafter zigzag flame bands are formed on the center and side air injection plates 4 and 5 along air ports 7 to lower the length of flame and conduct a high-load combustion. Further, among the zigzag flame bands the top portion on the downstream side is cooled by a secondary air flow supplied through top air openings 8, and hence the heating of a drum 14 can be prevented by a small quantity of the secondary air flow. By the above described construction, an extraordinary heating of burner constituting elements is prevented even if the burner is thinned while accomplishing the high-load combustion.

Title: Automatic sheet feeder
Inventor: FUJIMOTO HITOSHI
IPC: B65H31/22
Filed: 1993-02-08
Abstract: PURPOSE:To prevent a paper discharge tray from towering above a feeder main unit, when a sheet of large size is used, by setting a tilt angle, formed by a downstream upper part of the paper discharge tray with a feeder main unit set up surface, smaller than a tilt angle formed by an upstream lower part of the paper discharge tray with the feeder main unit set up surface. CONSTITUTION:A tilt angle theta2, formed by an auxiliary tray 4B drawn out from a paper discharge tray main unit 4A with a feeder main unit set up surface (platen glass 13), is set markedly smaller than a tilt angle theta1 formed by the paper discharge tray main unit 4A with the feeder main unit set up surface (0<=theta2<theta1). In this way, the auxiliary tray 4B, which is a downstream upper part of the paper discharge tray 4, is placed in a condition of almost horizontal soft crown with the feeder main unit set up surface, and here is loaded the downstream point end of a paper discharge sheet S2. Here certainly the downstream point end of the paper discharge sheet S2 comes into contact with a sheet S1 on a sheet paper feed base 1, but because of slight contact, a load is prevented from being generated at the time of feeding the sheet S1.

Title: Level control circuit
Inventor: IWAMATSU MASAYUKI
IPC: H03M1/18
Filed: 1987-02-27
Abstract: PURPOSE:To prevent the signal clip due to overflow by providing an electronic volume before and after a digital signal processing section and setting the volume of the post-stage to make through in setting the overall gain to be -g (a gain not overflowed)) or over and setting the volume of the pre-stage to make through when the overall gain is set below the gain -g. CONSTITUTION:In the case of the overall gain of 0--gdB, the volumes 20, 38 and 24, 36 are selected to make through and the volume 30 is controlled. The clipping of the signal waveform due to overflow of a digital signal processing section 14 is prevented against the input of the range from a level lower than the reference level by -gdB to the reference level to prevent the decrease in the permissible input. In the case of the overall gain of -g--infinity dB, the volumes 20, 38 are set to make through and the volume 30 is set respectively to -gdB to control the volumes 24, 36. Since a head margin of -gdB is formed to the digital signal processing section 32, the signal is inputted up to the reference level without being clipped and the decrease in the permissible input is prevented.

Filed: 1994-03-16
Abstract: PURPOSE:To improve the utilizing efficiency of incoming/outgoing VPs by taking a band of an outgoing VC and a status of an outgoing VP into account in the case of receiving and discriminating an incoming VC and taking a band of an incoming VC and a status of an incoming VP into account in the case of receiving and discrimianting an outgoing VC.

A device 305 stores a number of classes connected and a device 306 transfers a reception enable signal when the connection request call is within the range of a class dependent receptible number and a reception disable signal when not to a signal transmitter 307. Thus, narrow band VCs are connected to some degrees, the VC is not accepted and a broad band VC is accepted while leaving a residual band of the VP.

IPC: H04N5/335
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To photograph a video image without mis-reception of information by detecting a local strong incidence onto a light receiving face of an image pickup element, generating an offset signal to open an aperture by a prescribed value, and adding the offset signal to an output signal of an aperture control means that controls an aperture based on a mean luminance of a video signal. SOLUTION: A switch 4 is used to separate a video signal from a sample-and- hold circuit S/H 3 into odd numbered fields and even numbered fields. An average detection and hold circuit 5 outputs a mean value of video signal levels of an odd numbered filed, a comparator 6 provides an output of a signal with level '1' when the video signal of an even numbered field is higher than the mean value and a counter 7 counts number of pixels with a level higher than the mean level. An area comparison and DC offset voltage output device 8 discriminates presence of locally strong incidence when a rate of number of pixels with a higher level than the mean value is smaller than that of reference data and gives an offset voltage to a DC offset circuit 12.

Title: Four-wheeled vehicle
Inventor: TARIKI KEIJI
IPC: B60K17/04
Filed: 1989-03-01
Abstract: PURPOSE:To secure a floor space as well as to improve travel stability and engine cooling efficiency by tilting a cylinder of an engine forward, and setting up a muffler at the side and a belt driving pulley for rear-wheel drive at the side of the engine and in the rear of this muffler, respectively. CONSTITUTION:A muffler 40 is set up at the side of a forward-tilted cylinder 39 of an engine 18, while a fan 47 is connected to one end of a crankshaft, a driving pulley 48 for rear-wheel drive is connected to the other end, and a V-belt 49 is rolled on an interval between the driving pulley 48 and a driven pulley 28. Since the muffler 40 will not occupy a forward space of the engine 18, the space of a floor 6 is securable sufficient enough and, since the cylinder 39 is tilted forward, height of a seat 4 can be lowered, travel stability in a vehicle 1 is thus enhanced. In addition, since the muffler 40 is set up at the side of the engine 18, a running wind warmed by the muffler 40 will not hit on the engine 18, thus cooling efficiency for the engine 18 is improved as well.
