Patent JP-H1099764-A (JP)
Title: Coating applicator and method therefor
Inventor: WATANABE MASARU
IPC: B05D3/00
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To drastically lessen the loss of a coating liquid and to make a coating application thickness constant by combining and executing a traveling stage for a nozzle and/or base material, a stage for changing the outlet slit width of the nozzle and a coating stage for the coating liquid, thereby applying the coating liquid of arbitrary patterns on the base material or a substrate. SOLUTION: The coating liquid 7 is fed to the manifold 5 of the nozzle 1 by various liquid feed systems, is uniformly discharged in the coating width direction from the slit 4 and is applied on the base material 8 installed on a table 9. The coating width is changed by laterally moving a closure plate 2 from the central part by means of a bar 3, thereby changing the slit width. The moving quantity of the bar 3 is changed during the coating according to the program of a controller 11. The formation of the non-coated part is executed by closing the inlet of the slit 4 with the peripheral surface of the bar 3 and preventing the extrusion of the coating liquid 7. Then, the coating width is determined by the position in the transverse direction of the closure plat 2.  The coating width is thus arbitrarily changed by the movement and the coating is executed in the arbitrary patterns meeting the change of the coating width.

Title: Orienting method for liquid crystal optical element
Inventor: YUASA KOYO
IPC: G02F1/1337
Filed: 1988-08-24
Abstract: PURPOSE:To perform fast, continuous, and high-level orientation control through extremely easy and simple operation by specifying a bending direction when ferroelectric liquid crystal is oriented by bending deformation. CONSTITUTION:When the ferroelectric liquid crystal sandwiched between two flexible substrates is oriented by bending deformation, the bending direction is slanted nearly by the tilt angle theta of the liquid crystal or 90 deg.-theta from the optical main-axis direction (orienting direction) of the substrates. In another way, the longitudinal direction of the substrates is slanted by almost the tilt angle or 90 deg.-theta. In an actual device, a liquid crystal optical element 1 is heated by a heating device 4 to a temperature T1 and moved between two rotary rollers 2 and 3 which are held temperatures T2 and T3, thus orienting the liquid crystal. At this time, the tilt of the bending direction of the substrates by the two rollers 2 and 3 to a direction perpendicular to the main axes of the substrates is set to theta or 90 deg.-theta and the temperatures T1 - T3 are set properly.

Title: Shutter for disk cartridge
Inventor: HAYASHIDA HIDEO
IPC: G11B23/03
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce the distribution of residual stress in a molded product by providing a dam structure for adjusting the flow of a melted resin during injection molding in an integrated type shutter mechanism. SOLUTION: A melted resin press-injected from a gate 100 to flow toward a slider part 51 for smooth flowing is forcibly passed through the narrow sectional area parts of dam structures 101, 102 and 103 provided in a gate side from the slider part 51, and its flow is suppressed. For uniform formation on almost the full surface of a shutter plate, the opening sectional areas of dam structures 201 and 202 and 203 in this location are larger than those of the dams 101, 102 and 103, and thus a flow to both shutter plates is facilitated. Further, dams 104 and 105 and dams 204 and 205 prevent slightly easier flowing in a shutter plate 72 than a shutter plate 71, and the dams 104 and 205 function as flow adjusting dams.  In the process of forming such an integrated shutter mechanism by injection molding, the distortion or bending of a molded product is prevented, and the occurrence of burr is suppressed.

Title: Drawn picture communication equipment
Inventor: TANAKA JUNJI
IPC: H04N1/00
Filed: 1986-09-04
Abstract: PURPOSE:To simplify the operation by storing a picture signal inputted when it is detected that an opposite party is in the unconnection state, reading and sending the picture signal from the memory when it is detected the opposite party is in the connecting state to eliminate the need for retransmitting a drawn picture. CONSTITUTION:Dialing is given to a communication opposite party by a telephone set 9 in applying drawn picture communication, and when a communication opposite party responds to the dial, the execution of drawn picture communication is communicated. If the selection of the communication mode is forgotten at the reception side in case of the start of communication, since no reply signal is returned, a control circuit 4 at the transmission side detects that the communication mode is not selected at the reception side, drawn picture data are all stored in a memory 5 and no transmission is executed. When the reception side selects the communication mode during that time, the circuit 4 detecting the selection reads the drawn picture data stored in the memory 6 sequentially and sends them to a telephone line L via an FSK MO DEM circuit 7 and a demultiplex circuit 8. Thus, the reception side writes the picture into a picture memory 13 from the beginning and the need for the drawn picture is eliminated.

Title: Production of sintered compact
Inventor: OTSUKA AKIHITO
IPC: C22C33/02
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To easily produce a product having an extremely low coefficient of thermal expansion by mixing specific amounts of Fe powder, Ni powder, Co powder, and C powder, compacting the resulting powder mixture, and sintering the resultant green compact at specific temp. SOLUTION: A powder mixture is prepared by mixing the powders of Fe, Ni, and Co, having 5-50μm average grain size, so that they form a composition consisting of, by weight, 30-33% Ni, 5-7% Co, and the balance essentially Fe. C powder is added by 0.05-0.4wt.% to the powder mixture and these powders are mixed, by which a powdered raw material is prepared. This powdered raw material is compacted into a green compact. This green compact is sintered at 1,300-1,400 deg.C in a vacuum or hydrogen atmosphere and formed into a sintered compact. When the contents of Ni and Co deviate from respectively prescribed compositional ranges, the coefficient of thermal expansion is elevated. C is necessary for CO reaction. When C content is low, reaction is not accelerated and the densification of a sintered compact becomes difficult.  When C content is high, C remains in the sintered compact and the coefficient of thermal expansion is elevated.

IPC: H04N5/91
Filed: 1991-08-21
Abstract: PURPOSE:To provide a video tape recorder capable of stably recording signals such as a multiplexed character signal, in a video signal obtained by modulating a television broadcasting. CONSTITUTION:In first and second detectors 13, 14, vertical and horizontal synchronizing signals are detected and the position of an inputted character signal is discriminated. A character signal demodulated by a discriminator 16 and a data rate discrimination signal obtained by a synchronizing detection are stored in a first memory 17 with a position discrimination signal and are read.

Title: Method for controlling runout table
Inventor: TAMAGAWA HARUO
IPC: B21B39/12
Filed: 1990-08-07
Abstract: PURPOSE:To drastically reduce the variation of a backward tension to a rolled stock after it passes through a finishing mill by lowering the steed of each runout table in sequence by an amount of lag whenever the end of a rolled stock passes through sorted boundaries. CONSTITUTION:After the rolled stock 1 is rolled by the finishing mill 3, it is guided to a take-up machine 6 through many runout tables 4 and a pinch roll 5. Many these runout tables 4 are sorted by a prescribed number and the respective material detectors 10, 11, 12, 13 are equipped on those boundaries. Whenever these material detectors 10, 11, 12, 13 detect the end of the rolled stock 1, steed references which are reduced by an amount of lag (about 5%) in sequence are outputted. In this way, while the end of the rolled stock 1 moves on the runout table the variation of the backward tension can be kept small. Consequently, deterioration of the coil shape caused by a large change of the backward tension and flaws on the surface of the material caused by slip can be prevented.

IPC: H01L21/301
Filed: 1990-08-08
Abstract: PURPOSE:To prevent a chip from being cracked and from being picked up erroneously by a method wherein the side of a non-bonded face is irradiated with an energy beam, a chip-shaped component is held before it is picked up, the bonded part of the chip-shaped component is sucked from the side of the non-bonded face in synchronization with the completion of its holding action. CONSTITUTION:An ultraviolet irradiation apparatus 6 is turned on; the adhesive power of a chip fixation tape T is reduced. Then, almost simultaneously with the irradiation with ultraviolet rays, a collet 2 is lowered. In succession, a vacuum valve 4a of a vacuum apparatus 4 for suction use is opened; and a chip C is sucked. When this suction operation is completed, a chip-bonded part Ta of the chip fixation tape T is sucked via a suction opening 5a. Almost simultaneously with the completion of the suction operation, the collet 2 is raised in a state that it has sucked the chip C. Thereby, in a state that the adhesion power of the chip fixation tape T is lowered and that the chip C is held by the collet 2, a vacuum suction operation is executed. As a result, only the chip fixation tape T is sucked into the suction opening 5a by leaving the chip C, and the chip C is separated from the chip fixation tape T.
