Title: Surface flaw inspecting apparatus
Inventor: MORIYA SUSUMU
IPC: G01N21/88
Filed: 1989-06-13
Abstract: PURPOSE:To enhance the degree of agreement with the result of visual inspection by measuring the moving speed of a material to be inspected and the surface reflecting state of the material to be inspected, controlling the amount of light from a light source which illuminates the surface of the material and the amount of the light which is inputted into an image sensing part, and controlling the signal level of the background image of the material to be inspected. CONSTITUTION:In an illuminance measuring part B, light is emitted from a stroboscoptic light source 2' toward the surface of a material to be inspected 1. The image of the material to be inspected 1 is picked up by a TV camera 3' as a static image. The level of a background image signal is obtained based on the intensity of the image signal. The light emitting voltage of a storoboscopic light source 2 and the stop of a TV camera 3 are set with an intensity control part 15 for the stroboscop ic emitted light and a stop control part 16, respectively, so as to obtain the preset value of the background image signal value. Thus, illuminance for the material to be inspected 1 is controlled. Then, the light emitting voltage of the stroboscopic light source 2 and the stop of the TV camera 3 are set with respect to the moving speed of the material to be inspected which is detected with a speed meter 5, and the illuminance for the material to be measured is controlled.

IPC: H04L12/28
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To operate the network efficiently by allowing a receiver side to easily confirm occurrence of an aborted packet due to congestion of the network. SOLUTION: An input cell of an asynchronous transfer mode adaptation layer AAL-type 5 is received from an input terminal A and written in a cell buffer 106 via a selector 104. A final cell extract circuit 102 detects a final cell of the AAL type 5 with VCI=N from the received cell 1 and provides an output of a final cell selection signal 4 with respect to the final cell only with VCI=N. A VCI extract circuit 101 extracts the VCI from the input cell 1 and provides an output of a VCI selection signal 3 with respect to a cell with VCI=N only. A congestion cell generating circuit 103 generates a congestion cell 5 in a timing of the final cell selection signal 4. A congestion cell insert control circuit 105 outputs a congestion cell insert selection signal 10 when a buffer threshold level exceed signal 6 in a timing of the final cell selection signal 4 to throw the input of the selector 104 to a position D so as to select a congestion cell 5 as a cell buffer write cell 2.

Title: Cleaning sheet
Inventor: KITAMURA MASAMI
IPC: B24D11/00
Filed: 1988-06-16
Abstract: PURPOSE:To enhance the tensile strength of a cleaning sheet, improve its working property and elevate its cleaning effect by using a plastic film flocked with 0.005 to 2 denier short fibers for the sheet. CONSTITUTION:Short fibers ranging from 0.005 to 2 deniers are flocked on the surface of a plastic film (for examples, drawn or non-drawn films of polyvinylchloride, etc.).

Title: Semiconductor integrated circuit
Inventor: AKATSUKI TADAYUKI
IPC: G06F1/00
Filed: 1986-06-25
Abstract: PURPOSE:To make reliance on a power source small when judging momentary break of the power source by using a momentary break detecting means in analog way and making time constant of the detecting means large. CONSTITUTION:The state of waiting for detection of momentary break of power source is obtained by resetting a latch circuit 8 and then making reset input 10 L level. When an external supply power source 1 starts lowering due to momentary break, its variation is detected by a linear amplifier consisting of an inverter 2 and feedback resistance 3 through a coupling condenser 4. Here, output amplitude of the linear amplifier consisting of the inverter 2 and the feedback resistance 3 is determined by the transistor size of the inverter 2. When the threshold value of the circuit 8 is set to high level output of the linear amplifier beforehand, the result of detection by the linear amplifier is latched by the circuit 8. By this constitution, reliance on power source when judging momentary break of power source becomes small, and accordingly, the circuit is made stable for malfunction due to noise.

Title: Lens movement controller
Inventor: NAKADA MASAHIRO
IPC: G03B17/14
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To limit the moving range of a focusing lens group without using a mechanical focus limiter. SOLUTION: When driving of the lens group is stopped, a focusing limit processing routine is finished (step S302). When the lens group is in the middle of driving, a lens communication is performed and a distance code expressing the present position of the lens group is inputted to a camera control circuit (step S303). When a focus limit switch is in an off-condition, this routine is finished; however, when the focus limit switch is in an on-condition, limit position data expressing the limit position of a focusing area are read from an EEPROM (step S305). When the present position of the lens group is mutually different from the position expressed by the limit position data, this routine is finished. When they are mutually equal, the lens group is one the limit position of the focusing area, so that a focus limit flag is set to 1 (step S307).

Title: Print head and substrate therefor
Inventor: SUZUKI TOSHIO
IPC: B41J2/05
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To enhance ink resistance by forming a substrate to be provided with elements for generating liquid ejection energy of a material principally comprising high purity magnesium or nickel. SOLUTION: A magnesium substrate or a nickel substrate having purity of 99% or above is employed as a substrate 1 to be provided with elements for generating liquid ejection energy. Consequently, ink resistance can be enhanced and the lifetime of a head or the substrate can be prolonged. Alternatively, the substrate 1 may be formed of a material principally comprising high purity aluminum containing about 0.1% or less of silicon and iron, as impurities. Since a foreign matter, e.g. an intermetallic compound, is not produced, surface smoothness is enhanced and breakage of thin film pattern can be suppressed. High purity aluminum, magnesium or nickel may be provided at least in layer on the surface of the substrate 1.

Title: Induction heating apparatus
Inventor: TADANO HIDEAKI
IPC: F27B14/06
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To suppress the voltage in vacuum and prevent dielectric breakdown at any degree of vacuum and make melting possible in the vacuum by forming a conductive coating on the outside of an insulated induction coil and connecting this with an earth. SOLUTION: A levitation melting apparatus 1 dissolves molten metal 3 in a water-cooled copper crucible 2 without contamination in levitation state. At this point, the apparatus 1 is set in a vacuum container 6 and the melting is carried out in highly vacuum atmosphere. Consequently, degassing is carried out and oxidation is prevented and clean molten metal can be obtained. An induction coil 4 used for the apparatus is produced by forming a coating of a conductive coating 4c on the outside of an insulating coating 4b which insulates a conductor 4a, closely attaching the coil layers, and turning the coating 4c one time. Consequently, the impedance of the coating 4c is made small. Then, the coating 4c is connected with an earth. The coating 4c cut the circumference of the conductor 4a in the circumferential direction at least one point.  As a result, dielectric breakdown in vacuum can be prevented.

Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To quickly solve the problem of stuffing even in the case of being stuffed with stockpiling, by arranging air mats, which can be expanded/ contracted by feed/exhaust of the air, on the internal faces being in contact with the stockpiling in the bottom side walls and the internal faces being in contact with the stockpiling in a housing. SOLUTION: If stockpiling 5 containing moisture or stored for a long time is hardened and causes stuffing, exhaust valves 22, 27 are closed and at the same time feed valves 20, 25 are opened so that air is fed from air feed pipes 19, 24 to air mats 17, 18 via branch feed pipes 21, 26. Then, the air mats 17, 18 are expanded as expressed by a virtual line and after that the feed valves 20, 25 are closed so as to stop feeding of the air to the air mats 17, 18 and at the same time the exhaust valves 22, 27 are opened so as to exhaust the air inside the air mats 17, 18. The air mats 17, 18 are thus contracted again and the force of the stockpiling 5 causing the stuffing becomes unbalance so that the stockpiling flows down again.
