Title: Spindle device
Inventor: GOTOU TORAO
IPC: F16C32/06
Filed: 1984-03-15
Abstract: PURPOSE:To automatize the attachment and removal of a disc, by communicating the inlet ports of diffusers which are radially arranged at an circumferentially and equally spaced positions on the flange section of a spindle, with discharge passages for compressed air which is fed into bearing gaps so that the flow rate of compressed air is made variable. CONSTITUTION:When a valve 17 is closed, compressed-air fed into slight bearing gaps 13, 14 in the radial and thrust directions comes together in a discharge section 15, passing through a communication passage 21, and is discharged to the outside through a diffuser 19 so that vacuum is generated in the throat section 19a of the diffuser. The vacuum is effected in a shallow annular groove 10a' formed in the chuck surface (a) of a flange section 10a through a small hole 20, thereby a disc 11 is absorbed and held onto the chuck surface (a) to carry out a machining process. Further, when the valve 17 is opened, the discharge passage of compressed air from the discharge section 15 is changed over to a passage 16 to decrease the flow rate of compressed air in order to weaken the absorbing force, and therefore, the disc 11 may be removed. A solenoid valve may be used as the above-mentioned valve 17 to make it possible to automatize the attachment and removal of the disc 11.

Title: Lighting device
Inventor: KANEKO ATSUSHI
IPC: G09F13/04
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To simplify constitution of a display panel part, to make easy manufacture, to prevent stray light from arriving at the part excepting a required position and to realize an excellent lighting state by providing a light shield member fitted into a recessed part forming a bulged part from a rear surface side of a panel member to be arranged and covering the peripheral wall part of the recessed part. SOLUTION: When a light source is lighted, the light outgoing from the light source is made incident on a light transmission member 2a through the outer flange part 18 of the light transmission member 2a, and light transmits through the light transmission member 2a to arrive at an inner flange part 17. The light transmitting to the inner flange part 17 is emitted to the front side from the inner flange part 17, and transmits through the panel member 1 to be emitted to the outside through the top part 5 of the bulged part 4. At this time, since the light outgoing from the light source is light shielded by the light shield member 2b, it doesn't arrive at the peripheral wall part of the surface side of the panel member 1 of the expanded part 4.  Thus, only the top part 5 of the bulged part 4 becoming a peripheral part of a volume knob 3 is lighted, and the position of the volume knob 3 is displayed clearly.

Title: Twin roll strip casting apparatus
Inventor: YASUDA KAZUMI
IPC: B22D11/06
Filed: 1991-03-18
Abstract: PURPOSE:To provide a twin roll strip casting apparatus providing a carrying means, by which breakage of a cast strip come out from the twin roll is prevented and the cast strip can be carried to a coiler. CONSTITUTION:The hoop-state cast strip 6 come out from the twin roll forms a free loop 10. A driving device 9 for carrying the hoop-state cast strip is rotated in the arrow mark 12 direction and the cast strip is carried to the coiler. High pressure fluid is introduced from a fluid introducing hole 13 by a fluid cushion device 11 and injected from nozzles 14. Therefore, the hoop-state cast strip forming the free loop 10 is pressurized from the lower part by the fluid cushion of the high pressure fluid injected from the nozzles, and in the case of the short loop 10-1, as the cast strip is far from the fluid cushion device, the pressurized force is low, but as the dead wt. of the cast strip is light, the breakage is not developed because excess tension stress is not loaded. In the case of the long loop 10-2, the dead wt. of the cast strip is heavy, but as the pressurized force is high by the fluid cushion, the dead wt. of the cast strip is reduced and the excess tension stress is not loaded and the breakage of the cast strip can be prevented.

Title: Solid-state image pickup device, method and device for driving thereof
Inventor: MITSUI MITSUSACHI
IPC: H04N5/359
Filed: 1989-03-06
Abstract: PURPOSE:To prevent the degradation of a smear characteristic and of an afterimage characteristic by setting the starting time of a driving pulse for a transfer gate more than a specified time so that a charge can not be injected from a charge sweeping-out means to a photoelectric converting element. CONSTITUTION:For a photogate pulse waveform VPG to be impressed to a photogate 6, the rise time is delayed more than 1musec in comparison with a conventional waveform. When the starting time is delayed, the degree of a potential change in a P<-> well 10 by coupling between the photogate 6 and P<-> well 10 is reduced. As a result, since the electronic injection of a photodiode 1 is not generated from an overflow gate 5, the picture quality of an image pickup picture can be prevented from being degraded. For example, when a starting time t1 of the pulse to be impressed to the photogate 6 is set to 10musec, an overflow gate voltage to start the electronic injection can be changed from 5.5V to 4.5V. Thus, the level of a saturation signal is improved to be double in comparison with a conventional example.

Title: Washing method of permeable membrane module
Inventor: AZUMA TATSUO
IPC: B01D65/02
Filed: 1984-03-16
Abstract: PURPOSE:To prevent the contamination of a permeate side by a pyrogen by enabling backwashing using a permeate, by hermetically closing the permeate side in a gas preliminarily filled state while raising raw water pressure in a raw water side for a predetermined time and subsequently falling the same. CONSTITUTION:If circumferential sterilized gas is naturally substituted with a sterilized liquid after a permeable membrane module 7 is sterilized, the gas in the permeate side of the permeable membrane module 7 can be filled. At the time of washing, a permeate take-out valve 3 is closed. Raw water transmits a membrane 9 from an open raw water inflow valve 1 and is gradually accumulated in the permeate side while compresses gas to raise the pressure in the permeate side. Next, when a raw water discharge valve 2 is opened, the pressure in the raw water side is lowered at a stroke. The permeate 15 accumulated in the permeate side is flowed to the raw water side by the expansion force of the compressed gas to perform backwashing. The fine suspended substance accumulated on the surface of the membrane 9 is released and discharged out of the system while goes with the flow in the raw water side. This operation is repeated several times by the opening and closing of the raw water discharge valve 2.

Abstract: PURPOSE:To classify and detect various kinds of line abnormality with simple constitution by obtaining a skeleton image by repeating a process (n) times, wherein the binary image of a wiring pattern is deleted from the background side one by one picture element. CONSTITUTION:The wiring pattern formed on a printed board 101 is lighted by a diffusion lighting device 104 and inputted as a light-shade image by an image input means 102. This image is subjected to binarization 105 and a line- thinning processing means 106 performs the process, wherein the wiring pattern is deleted from the background side one by one picture element with a predetermined number of times as to all picture elements and then outputs the number of times of repetition of deleted object picture elements and the skeleton image. Then a distance image converting means 107 outputs a distance conversion image for which the number of times of repetition is imparted as the value of the distance of the wiring pattern from the background. A flaw detecting means 108 compares the distance value of the distance conversion image with >=1 optional set threshold values (maximum value or minimum value) along the skeleton image according to the output image and the skeleton image to detect the flaw in wiring pattern width.
