Title: Method of electrophotographically forming luminous screen body structure on inner surface of face-plate panel of cathod-ray tube
Inventor: JIYOOJI HAABAATO NIIDAMU RIDOR
IPC: H01J9/22
Filed: 1993-01-26
Abstract: PURPOSE: To form an absorptive matrix having large opacity. CONSTITUTION: A CRT panel 12 is covered with a conductive layer 32, and is covered with a photoconductive layer 34 substantially uniformly charged. The selected region of the photoconductive layer 34 is exposed by chemical rays through a shadow mask to influence electric charges on the photoconductive layer 34. The unexposed region of the photoconductive layer 34 is developed by means of dry powdered absorptive screen material charged by frictional electricity. While the photoconductive layer 34 is reexposed and charges are kept on a region covered with absorptive screen material, the reexposure further discharges an exposed region to enhance voltage contrast between the exposed and unexposed regions of the photoconductive layer 34.  By the second development of the unexposed region, absorptive material is attached to previously attached absorptive screen structure material to increase the opacity of a matrix 23.

Title: Single-phase autotransformer
Inventor: HOTSUTA AKIRA
IPC: H01F30/02
Filed: 1981-03-06
Abstract: PURPOSE:To prevent the change of tertiary voltage according to the position of a tap, and to obviate the reduction of the impedance of tertiary winding by winding exciting winding an the tertiary winding on the same side leg core. CONSTITUTION:Series winding 1 and shunt winding 2 are wound concentrically on a main leg 71, and tap winding 4, the tertiary winding 30 and the exciting winding 50 are wound on the side leg 70. The winding 4 is connected in series with the neutral point side of the winding 2, and the winding 50 is connected in parallel with the winding 2 and both terminals u, v of the series connecting circuit of the winding 4. The excitation of the core leg on which the winding 50 is wound doet not change according to the position of the tap because voltage between the terminals u, v is constant. The sectional area of the side leg on which the winding 30 is wound is the half of the main leg. Accordingly, impedance between the winding 50 and 30 in the case when the winding 30, 50 is wound on the side leg is quadrupled as compared to the case when the winding is wound on the main leg because induced voltage per one winding of the winding is halved.

A substrate 10 of a incombustible magnetic material is formed by laminating the layers, in such a way that the via holes 12 and 13 of the layers are respectively aligned with each other. Then the top and bottom faces of the substrate 10 are coated with a second conductive material 16 without expanding the dimensions of the via holes 12 and 13 by not performing, for example, any additional punching step for forming via holes to be connected to the via holes 12 and 13, and conductive windings are formed by connecting the side-wall coatings of the adjacent via holes 12 and 13. Finally, the substrate 10 is burnt and electroplated with an additional metal, such as copper, etc., as a conductive material.

Title: Coaxial type circulator
Inventor: KONDOU YASUYUKI
IPC: H01P1/387
Filed: 1980-03-14
Abstract: PURPOSE:To suppress the production of unnecessary mode, by locating a thin resistor along the entire circumference of ferrite external side surface. CONSTITUTION:The circulator is operated by applying DC magnetic field with the magnet 6. The electric field produced at this time is thought to be a shape wound in the housing 1, and it is considered that it is concentrated in the ferrite with high dielectric constant. The part surrounded with the ferrite 4 for the inner conductor 3 is considered to be a cylindrical resonator forming the cylinder. If the construction of the circulator causes resonance as a whole, the electric field produced at outside of the ferrite 4 is absorbed in the resistor 8. As a result, the effect which can suppress the unnecessary resonance is great.

Title: Test device for optical rain sensor
Inventor: SHIMIZU SHINJI
IPC: F16H1/28
Filed: 1989-02-10
Abstract: PURPOSE:To accomplish desired rainfall speed and rainfall interval by attaching the needle for pseudo rainfall which passes through the optical sensor of an optical rain sensor to a planet gear and making the planet gear rotate and revolve and a sun gear intermittently rotate. CONSTITUTION:The rain sensor 1 which optically detects a raindrop which passes through the optical path is tested by making the needle 21 pass instead of the rain drop. By consecutively rotating an intermittent motor 25 for driving a sun, the planet gear 22 revolves around the sun gear 23 while rotating by a consecutive motor 24 for driving a planet and the tip of the needle 21 draws a locus 30 while moving. The locus 30 of the needle periodically provides a peak 31 and trough 32. When the peak 31 of the locus gets in the optical path of the rain sensor 1, a 'rainy' state is obtained and when the trough 32 is opposed to the sensor 1, a 'fine' state is obtained. Therefore, the state is switched from 'rainy' to 'fine' and from 'fine' to 'rainy' by intermittently rotating the gear 23 by a specified angle, so that the rainfall interval is set the natural number multiple of a revolutional period according to the number of switching times.

Abstract: PURPOSE:To minimize a bit error rate by estimating a ratio of an energy ES per one transmission symbol of a reception signal in a communication line to a noise power density NO and activating the AGC circuit optimum with respect to the ES/NO. CONSTITUTION:An ES/NO estimate device 10 compares a signal coded again from composite data with a signal obtained by delaying the MSB of soft discrimination data outputted from an A/D converter 6 by a decode delay time of an error correction circuit 8. That is, a decoding bit error rate BER of a channel is obtained from data of the circuit 8 before and after correction, the ES/NO is estimated and the result is outputted to an AGC circuit 9. The circuit 9 stores an optimum threshold level interval versus ES/NO characteristic in advance, compares a level of a base band signal inputted to the converter 6 with the ES/NO outputted from the ES/NO estimate device 10 to control the attenuation of a variable attenuator 2 so as to optimize the threshold level interval. Thus, level fluctuation of the reception signal in the AGC circuit is absorbed.

Title: Production of resin seal type semiconductor device
Inventor: TATENO HIDEO
IPC: H01L23/48
Filed: 1978-03-20
Abstract: PURPOSE: To remove easily a thin flash, which is generated at a resin seal time, by jetted flow of liquid or air.  
     CONSTITUTION: Water is jetted from a nozzle to blow off the thin flash between a resin seal body and a lead. By this method, washing of organic materials becomes needless after processing because dirt is not sticked. Water can be used repeatedly by filtering, and the device can be prevented from being injured. When organic chemicals such as alcohol are used in stead of water, the drying process is shorted, and the drying process becomes needless if the thin flash above can be removed by air.
