Patent JP-H10242836-A (JP)
Title: Semiconductor integrated circuit
Inventor: TAKAHASHI KATSUHIKO
IPC: H01L21/822
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain a push-pull output circuit which has neither a drop in output level nor a leak current by connecting a pull-up P channel MOSFET in parallel to a push-side output transistor constituting an output circuit, and providing an MOSFET which cuts off its leak current. SOLUTION: Series-connected MOSFETs N1 and N2, and N3 and P3 for preventing a leak current of the pull-up MOSFET P1 are connected between a source voltage Vcc and an output node n1. In an active state, the MOSFET N1 has its gate applied with the source voltage Vcc, so the back gate of the pull-up MOSFET P1 is held almost at Vcc. No leak current flows through a diode parasitic between the source-drain area and well area of the P1. When a voltage higher than Vcc is applied to an output terminal OUT, the MOSFET N1 is inverted and the P1 is shielded from Vcc to prevent the leak current.

Title: Device for measuring gear temperature
Inventor: HISHIKARI ISAO
IPC: G01J5/10
Filed: 1979-04-13
Abstract: PURPOSE:To accurately measure the temperature of the tooth surface of a gear by synchronously rectifying the radiated energy detecting signal from the tooth of the gear via a synchronous signal corresponding to the tooth of the rotating gear. CONSTITUTION:Since the teeth train 1a of a rotating gear 1 consists of a tooth 1a and other portion, it is focused by a focusing lens 2, detected by a detector 3, amplified by an amplifier 4, which produces a signal output becoming alternative signal waveforms of the detecting signal corresponding to the tooth surface of the teeth train 1a,... and a zero point corresponding signal as shown on Figure a. On the other hand, the synchronous signal of a synchronous signal generator 6 becomes a pulse signal shown in Figure b corresponding to the tooth of the gear. Therefore, a synchronous rectifier circuit 5 sample-holds the detection signal shown in Figure a by the synchronous pulse signal shown in Figure b, and produces only the detection signal corresponding to the tooth 1a of the gear 1 shown in Figure c to the output terminal 7 so as to measure the temperature of the tooth 1a.

Title: Liquid crystal display device
Inventor: MIYOUDOU SHIGERU
IPC: G09F9/30
Filed: 1983-03-18
Abstract: PURPOSE:To obtain a high-luminance display face with low power consumption by arranging a radiation source, which radiates essentially ultraviolet rays, instead of a lamp radiating a white light and arranging a phosphor, which converts ultraviolet rays to visible rays, instead of a filter which converts the white light to a color light. CONSTITUTION:Ultraviolet rays radiated from an ultraviolet-ray lamp 5 are made incident to phosphors 6R, 6G, and 6B, and red, green, and blue lights are radiated from phosphors 6R, 6G, and 6B respectively and are made incident to a liquid crystal panel 1. At this time, when transmission factors of picture elements 1R, 1G, and 1B through which color lights are transmitted are changed independently of one another, proportions of luminous fluxes of red, green, and blue lights which reach an observation side 4 are changed, and various colors are displayed in the observation side 4 with the additive mixture of colors by this liquid crystal display device. In this case, though the power consumption of the lamp 5 is equal to that of conventional lamps, more luminous fluxes are made incident to a liquid crystal panel 1, and a high-luminance bright display face is displayed on the observation side 4. Thus, the high-luminance display face is displayed on the observation side with a low power consumption.

IPC: H01L21/822
Filed: 1991-02-19
Abstract: PURPOSE:To test an integrated circuit inexpensively and simply without labor of polishing a crystal, accurately aligning by coating a wafer with a material having a varying double refractive index for an external electric field, orienting it and patterning only a necessary position. CONSTITUTION:An IC wafer 2 to be measured is coated with an organic optical material 1 in which organic nonlinear optical material is dispersed in and bonded to a polymer material. Then, a pattern is formed on a part necessary to be measured. Thereafter, a high electric field is applied to orient an electric field of the material 1. The material 1 oriented by a direction of the electric field is varied in double refractive index with a best sensitivity for a variation in an electric field perpendicular, i.e., longitudinal to the wafer 2. A metal wiring 6 to be a target to be measured is irradiated with a laser light, and a polarizing variation in a light reflected on the wiring 6 is detected. Since a vertical electric field is dominant on the wiring 6, it can be effectively detected by the material 1 oriented perpendicularly to the surface of the wafer 2.

Title: Structure for giving overflow alarm when liquid in container overflows
Inventor: MORIZAKI HIROSHI
IPC: B65D90/48
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To drastically reduce the frequency of liquid overflowing from a top opening part in filling liquid without changing the shape of an outer appearance and little reducing internal volume compared with a traditional container. SOLUTION: A partition is provided in a container so as the rate of liquid level rise and liquid flow in filling liquid can be greatly changed temporarily. The partition 3 is fixed on the inside face near the spout 1 of the container 2 not completely separating the space in the container 2. As to the partition 3, as long as it can make a liquid level prevented from going up because of the same and a liquid level which can go up without the interference of the same, this can be any shape having a part not contacting the container 2, for instance a simple square shape in a tube container.  In order to vibrate the container 2 or to suddenly change a liquid filling sound, it is effective for the partition 3 and the liquid level to have contact in a wide area simultaneously, and thus it is desirable that the contacting face of the partition 3 with the liquid level is flat and moreover the partition 3 is mounted parallel to the liquid level.

The two photodiodes are then divided by selective mesa etching with normal exposure technology. After that, an SiN surface protection film 6 is formed in the thickness of -1500Angstrom on the whole surface by the phasma CVD method. Then, the SiN film is selectively removed with normal exposure technology and each p and (n) area is electrically joined.
