Title: Manufacture of thermocuring resin laminated sheet
Inventor: IIDA TAKAHISA
IPC: B32B37/10

Abstract: PURPOSE:To eliminate the uneveness from the surface of a substrate and thereby increase drilling processing efficiency by using woven glass cloth which is made brittle as an intermediate layer and using a specific weight of unwoven glass cloth on the surface of the woven glass cloth. CONSTITUTION:Epoxy resin which is made brittle so that the bending strength of a laminated plate reaches 50 kg/mm<2> both in vertical and horizontal directions is impregnated with thermocuring resin varnish such as epoxy resin, then a dried prepreg is used as an intermediate layer and the prepreg which is impregnated with thermocuring resin varnish and dried is applied, as a surface layer, on the unwoven glass cloth weighing 100 to 150g/m<2>. After this, a desired number of these surface layers and intermediate layers are laminated and copper foil is placed together. These are thermally molded under pressure. To make the woven glass cloth brittle, a variety of methods are available which are heat-cleaning at high temperatures of 400 deg.C or higher for a comparatively long time, soaking in an acid or alkali liquid and opening the fibers of a glass cloth mechanically. The unwoven glass cloth should preferably be of 7 to 12 mum monofilament in dia. and 9 to 19mm fiber length. The unwoven glass cloth also should preferably be heat-resistant and less water-absorptive for binder and coupling processes.

Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To quicken a scanning speed and minimize a time which is not used for discharging, but wasted by separating the electrodes of a panel into two groups, and applying scanning pulses having the positive polarity to one group and scanning pulses which have the same amplitude and different sign to the other group. SOLUTION: The whole panel is divided into an upper screen and a lower screen. The electrodes of the upper screen are denoted as S and C and the electrodes of the lower screen are denoted as S' and C'. In this case, the electrodes C and C' are common electrodes and implement only a sustaining function and the electrodes S and S' are scanning electrodes and implement the sustaining function and a scanning function. Pulses with the negative polarity are inputted to the electrodes S and C and pulses with the positive polarity are inputted to the electrodes S' and C'. Thus, the electrodes are separated into S and C, and S' and C' and their voltages are made opposite in polarity. Consequently, while the sustaining pulses are applied to the upper electrodes S and C, the lower electrodes S' and C' as the electrodes of the other group can be scanned.

Title: Optical branching/inserting device and optical gate switch
Inventor: SHIMOMURA HIROSHI
IPC: H04B10/29
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To compact a wavelength light branching/inserting device. SOLUTION: Signal light of 1550 nm wavelength is inputted to an optical transmission line 110. In the case of passing the signal light of 1550 nm wavelength, the signal light is reflected by a variable reflectance mirror 50 and outputted to the line 110 again. In the case of branching the signal light, a part of the signal light inputted to the line 110 is outputted to an optical transmission line 121 connected to an optical branch 11 and then inputted and received by a light receiver 71. When a branch ratio for connecting the branch 11 to the receiving side is reduced, an optical loss by the branch 11 can be suppressed at the time of passing signal light through the circuit. In the case of inserting signal light, the reflection factor of the mirror 50 can be optionally changed from 100% to be complete reflection down to 0% to be a transmission state.  When the mirror 50 is turned to the transmission state, signal light sent from the line 110 is not reflected, signal line of 1550 nm wavelength outputted from an optical transmitter 81 to an optical transmission line 120 is transmitted through the mirror 50 and outputted to the line 110.

Filed: 1989-11-30
Abstract: PURPOSE:To surely clean tank water and to smoothly feed water to a coffee extractor by providing a water cleaner so as to face the outlet of a reflux flow passage from which hot water emerges and to position above a feed water tank. CONSTITUTION:The water cleaner 12 positioned to face the outlet of the reflux flow passage 10 is provided in a cap 13 of the feed water tank 2. During the temperature of the water in the tank 2 rises up to the prescribed value, the water emitted from a feed water path 7 is heated on the way by a heating means 4 and arrives at a selector valve 9, from which the water recirculates from the reflux flow passage 10 to the feed water tank 2. The reflux flow passage 10 is closed and this time the hot water is fed to the coffee extractor when the water in the tank water is heated up to a prescribed temp. by the circulation operation. The water cleaner 12 removes bleaching powder, trihalomethane, etc., from the tank water during the circulation. Since the filter media, such as active carbon, in the water cleaner 12 exist on the outlet side of the reflux flow passage 10 to which the hot water is supplied, the cleaning efficiency of the water cleaner 12 is good and the water passability is not hindered.

Then the photoresist pattern 120B is fluidized by heat treatment to shrink the opening part.  Since the photoresist compsn. used consists of a polymer mixture having a large contrast and easily controllable fluidity, the photoresist pattern 120C which regulates the opening part with a small critical dimension can be formed.

Abstract: PURPOSE:To ensure that a constantly stable recording state is maintained, if the air volume of an ink chamber increases by providing an ink distributor which is connected to the end part of an ink supply pipe, then is stored and installed in the ink chamber and is equipped with openings on the periphery. CONSTITUTION:If a signal voltage is applied to electrodes 109, 114 using a signal source 115 during recording, a meniscus Io is aspirated through an ink discharge orifice by an electrostatic force based on the potential difference of the signal voltage, then the ink is scattered through an air stream flowing out of an air discharge orifice 108 and sticks to object to be recorded ahead for recording. In this case, if air A is introduced from the ink discharge orifice 107 or from the connection part of an ink supply pipe 111 by impact of a recording head 100, the air A in the ink chamber 106 increases, and the air A is introduced into the ink distributor 116 from the opening 117a above openings 117a, 117b..., while ink I' remains in the ink distributor 116 through the lower opening 117b. Consequently, the ink supply pipe 111 becomes submerged in the stored ink I' inside the ink distributor 116, and is retained in a closed state to prevent air to intrude.

Title: Method for compressing image data
Inventor: TOSHIKAWA TOSHIYUKI
IPC: H04N1/419
Filed: 1990-11-16
Abstract: PURPOSE:To prevent a compression effect from being lowered even when a lot of short white or black picture element lines are generated by mixing non- compressed data and compressed data on one scanning line of image data. CONSTITUTION:An input control part 11 inputs the image data and judges the continuation of white or black picture elements. When the picture elements are continued over 5 bits, they are transmitted to a compression processing part 12 and when the picture elements are continued less than 4 bits, they are transmitted to a non-compression processing part 13. The compression processing part 12 executes the compression processing of data by a one-dimensional encoding system, and the non-compression processing part 13 outputs the input data to an output control part 14 as they are. According to the order of the input data, the output control part 14 builds up the compressed data and the non- compressed data and outputs them after adding an identification code. Thus, even when a lot of short white or black picture element lines are generated, the compression effect is not lowered.
