Title: Self-protected integrated circuit to inversion of polarity of power supply battery
Inventor: KURAUDEIO KONCHIERO
IPC: H01L21/822
Filed: 1989-09-13
Abstract: PURPOSE: To self-protect for inverted polarity of a power supply battery by a method wherein a common drain region is provided in two DMOS power transistors in an integrated circuit. CONSTITUTION: For example, an N<+> type buried layer 9 doped reversely to a semiconductor substrate 4 is formed on the substrate 4 in which P type impurities are doped slightly. This buried layer 9 comprises a low resistivity portion of a drain region D1-D2 shared by both of transistors T1, T2. When a supply voltage VC is applied, the transistor T2 becomes conductive, and when polarity of a battery 2 is reversed, an integrated circuit 1 connected with a power actuator T1 is protected. When a device driver is operated, a current supplied from the transistor T1 via the second protection transistor T2 flows at a load RL. When polarity of the battery is inverted, the transistors become nonconductive, and both the driver and the load RL are protected.

Title: Tape recorder
Inventor: KABURAGI HIDETAKA
IPC: G11B15/093
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To realize a highly accurate tape-running control by detecting the number of pulses proportional to a rotating speed of a reel and then execute logarithmic transformation and inverse logarithmic transformation with a microprocessor to calculate a tape running time based on the particular formula. SOLUTION: A tape 3 is wound around a supply reel 4 and a takeup reel 5 which are provided in the equal winding diameter and providing a plurality of projections on the reel base. Detectors 6, 7 detect such projections with a photocoupler and output the number of pulses Ns, Nt proportional to the rotating speed. A microprocessor 8 calculates the tape running time T depending on Ns, Nt and displays it on a display unit 9. Here, the running time T can be obtained from the formula using the logarithmic transformation and inverse logarithmic transformation when the pulse angle of projection is defined as rad, tape line velocity as mm/s and tape winding area as Smm<2> . Thereby, the tape running time can be obtained within a short calculating time, it is displayed and tape running control is executed with a higher accuracy.

Title: Manufacture of discharge tube for high pressure discharge lamp
Inventor: FUJII KENICHI
IPC: H01J9/24
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To prolong the lifetime of a high pressure discharge lamp by suppressing occurrence of devitrification phenomenon such that the quartz glass tubing of the discharge lamp goes in devitrification during lighting to cause drop of the light flux to lead to exhaustion of the life, chiefly deriving from reaction of the quartz glass tubing with the encapsulated substance. SOLUTION: A blow gas 4 used when a quartz glass tubing 1 is formed in a spherical or pseudo-spherical shape should be pure He or a gas containing He at least 5vol.% He. The He having a small atomic radius is intruded into network gaps in the softened discharge tube to expel water/moisture and various impurities such as H2 O and OH radical which may accelerate detrivification, so that devitrification of the discharge tube while the lamp is ligting can be suppressed, and a long-life high pressure discharge lamp can be attained.

Title: Data discriminating circuit
Inventor: ISONO SOICHI
IPC: G11B5/09
Filed: 1987-09-24
Abstract: PURPOSE:To eliminate to miss detecting a peak by comparing a standard value and an actual read-out signal, and discriminating a reproducing peak. CONSTITUTION:A holding means 9 of a read-out signal holds a read-out signal for a sufficient time when comparing and detecting means 10-70 compare a read-out signal value and a series of values (standard values) which have been determined in advance. The read-out signal increases hourly and continuously from 0V, decreases after it has reached the peak, becomes 0V, further decreases and reached the peak of a negative side, and thereafter, increases again, and returns to 0V. This waveform which reaches the peak from 0V and returns to 0V again is compared with the standard value, and by detecting a standard value which coincides, a position of the peak is determined. That is, in case of the amplitude which can discriminate whether the read-out signal is larger or smaller than 0V, the peak position can be determined, therefore, even if a difference of crest height of the peak of the read-out signal at the time when a waveform interference exists and at the time when it does not exist becomes large, it does not occur to miss detecting the peak.

Abstract: PROBLEM TO BE SOLVED: To prevent the bias or bowed filling of the recording medium by oscillating an intermediate plate energizing member around the predetermined fixed position freely along a direction of extension of other edge, and oscillating an intermediate plate similarly with the oscillation of the intermediate plate energizing member. SOLUTION: An intermediate plate energizing member 162 is fixed to a shaft 120 by one stage bis 164. This fixing position faces a central part of other edge of an intermediate plate 112. Namely, the stage bis 164 is positioned just under a central part of the intermediate plate 112 in the cross direction (an arrow B direction). Since the intermediate energizing member 162 is fixed to the shaft 120 by the stage bis 164, the intermediate energizing member is freely oscillated around the fixed position in an arrow C direction along the other edge extending direction (the arrow B direction). A Z-shaped part of one edge of the intermediate plate 112 is inserted into a hole formed in a bottom wall 114a of a cassette container 114 in the loose condition. With this structure, the intermediate plate 112 is oscillated similarly with the oscillation of the intermediate energizing member 162.

Title: Image compressing method

IPC: H04N7/18
Filed: 1992-08-13
Abstract: PURPOSE:To transmit much more image information by transmitting reduced gray scale images and transmitting an error component on the middle stage in the case of enlarging this gray scale image into the original size. CONSTITUTION:Gray scale original images IM0 are reduced by 1/2 at the ratio of a length, and stepwise reduced images IM2-IM16 are successively generated. Next, the error components at the time of restoration are successively generated starting from the minimum image. Then, these components are expressed as stepwise binary images DELTA(IM8)-DELTA(IM0). When the stepwise binary images are generated, at the same time, a coefficient DELTA8 is calculated as the representative of the error of stepwise enlarged images corresponding to stepwise reduced images. Simultaneously, an image multiplying the stepwise binary image to this coefficient is generated, and stepwise weight error images IM''8-IM''2 adding this image and the stepwise reduced images are generated. These images are successively generated for each step of enlargement. Stepwise enlarged images IM'8-IM'0 in this enlargement processing are as large as the original image size.
