Patent JP-H03211895-A (JP)
Title: Printed circuit board
Inventor: TANIMOTO MASAKI
IPC: H05K3/34
Filed: 1990-01-17
Abstract: PURPOSE:To obtain a printed circuit board having high flatness of its surface without reducing filling properties of solder in a through hole of the board by forming the width of a land to be exposed around the hole and formed of a solder-resist layer at 0.15mm or less. CONSTITUTION:A solder-resist layer 4 is not formed at the part of a through hole 3 and in the vicinity of the hole 3. A land 6 to be exposed is formed around the hole 3 of the so-called void part 5 of the layer 4, and the width of the land is formed 0.15mm or less. Since the land 6 is small, the area to be welted by solder spreading along the metal of the land 6 is largely limited by the layer 4, and it does not almost protrude out from the layer 4. Thus, a printed circuit board having high flatness of its surface without reducing filling properties of the solder in the hole 3 of the board is obtained.

IPC: A61K35/583
Filed: 1980-01-29
Abstract: PURPOSE:To lower costs by using the poisoning liquid of hime habu ''Trimeresurus okinavensis'') (a poisonous snake common in the Ryukyu islands), as an essential component. CONSTITUTION:A hime habu is held alive and is caused to discharge snake poisons onto a laboratory dish. A multiplicity of these are collected and are centrifugally separated at about 4 deg.C by a cooling centrifuge. The supernatant thereof is desiccated in the frozen state and this frozen and desciccated matter is used as a blood coagulation accelerator. In use, a required amount of said accelerator which is the frozen and desiccated matter is dissolved in physiological salt water and is prepared to a concn. about the same as that of snake poison liquid. This is passed through a membrane filter of about 0.45mum pore size to make germ-free blood-clot enzyme liquid, after which a stabilizer, a dispersant, etc. are added to prepare enzyme liquid which is used as a blood coagulation accelerator as it is or after it is desiccated by freezing. Thereby, the blood coagulation agent of low costs is obtained because a large number of hime habu are living in the Amami Islands and their capturing is easy.

Title: Circuit for correcting internal raster distortion
Inventor: PEETAA EEDOUARUTO HAAFUARU
IPC: H04N3/233
Filed: 1995-01-23
Abstract: PURPOSE: To provide the inside raster correcting circuit which can adjust a correction quantity and the whole sigmoidal corrected shape. CONSTITUTION: A modulating circuit Q1 of the correcting circuit supplies a correction current i2 to sigmoidal forming capacitor C23 so as to modulate the voltage across a deflecting coil LH correcting inside raster distortion. The frequency of the correction current is lower than a line frequency for inside pincushion or barrel distortion correction. A frequency for correcting secondary inside pincushion or barrel distortion is higher than the line frequency. The correction current in the sigmoidal capacitor may be in either of the same direction with and the opposite direction from a deflecting current, so additive or subtractive correction is obtained. An inside correction quantity can be adjusted irrelevantly to outside raster correction. The modulating circuit is driven with deflecting electric power and does not depend upon a flyback transformer T20 .

Title: Memory control system
Inventor: HASEGAWA KENICHI
IPC: G06F15/16
Filed: 1986-01-17
Abstract: PURPOSE:To extend an address space by switching the address selectively to the access address from the second processor and that from the first processor to access a read/write memory. CONSTITUTION:When the first processor 1 writes data in a RAM 4, the first processor 1 issues a prescribed address and a write instruction (R/W=1), and the address is led to an address selector 5, and contention to the access address from the second processor 2 is avoided to perform the write access to the RAM 4. At this time, write data (W/D) is issued and is supplied to the RAM 4 through a data selector 6. When the first processor 1 accesses a ROM 3, the first processor 1 issues a prescribed address and a read instruction (R/W=0), and a decoder 7 issues a chip select signal to the ROM 3, and contents of the ROM 3 are read. Thus, the address space in the first processor side is practically extended.

So that the registered No. of the undisplaceable rear number plate is detected even through the front number plate is illegally displaced. As a result, the reading accuracy is improved for the registered Nos. of cars.

Title: Automatic gain control circuit
Inventor: KAWASE MASARU
IPC: H04N9/87
Filed: 1990-01-19
Abstract: PURPOSE:To simplify the constitution of a recording and reproducing device by making the response speed of automatic gain control changable corresponding to recording and reproducing. CONSTITUTION:In the case of recording, a switch 80 is changed over to a recording side, a time constant circuit 79 is connected to a synchronous signal level detector 76 and a time constant is set to a large value. This is because a problem that the amplitude level of a signal is changed rapidly on the recording is not generated. In the case of reproducing, the switch 80 is changed over to a reproducing side, the time constant is made small and by making the response speed of level detecting fast, it is made to be able to follow up sufficiently also to migration between tracks. On the other hand, in the case of reproducing the track which does not have a synchronous signal, a bias is given from a bias circuit 81 to a synchronous signal level detector 76, the detector 76 is made to act at an action point determined in advance, the amplification degree of an amplifier 74 is made a value determined in advance and the level of an output signal is made not to be a maximum value or a minimum value. Thus, an identical automatic gain control circuit can be shared by the recording and the reproducing.

Title: Current collector for electric railcar
Inventor: CHIKAMATSU HIDEAKI
IPC: B60L5/00
Filed: 1985-01-21
Abstract: PURPOSE:To stably collect a current by detecting the speed of an electric railcar, and driving a lifting force regulating mechanism by the output of a lifting force regulating amplifier in response to the speed to lift a current collector, thereby preventing a slide plate from wearing over a full speed range. CONSTITUTION:The speed of an electric railcar is detected by a tachometer generator 2 coupled with a wheel 1 of the railcar, and input to a lifting force regulating amplifier 3. This input is shaped in the waveform by an input buffer amplifier 4, converted by a pattern generation amplifier 5 into a lifting force pattern signal in response to the speed signal, amplified by a power amplifier 6, and converted into a lifting force signal 31. A lifting force regulating mechanism 7 is driven by the signal 31 to alter the lifting force of a current collector 8. Thus, the lifting force is weakened at a low speed to reduce the wear of a current collector, the lifting force is strengthened at a high speed to reduce the arc damage due to the disconnection of a line. Thus, the wear of the current collector is reduced over a full speed range to stably collect a current.
