Title: Ferroelectric liquid crystal display element
Inventor: ISHIKAWA MASAHITO
IPC: G02F1/133
Filed: 1989-06-12
Abstract: PURPOSE:To eliminate the local unequalness of display colors and to allow a high-grade display with good visibility by adding a means for converting the polarization state of the transmitted light transmitted in the parts where the thickness of a liquid crystal cell varies locally and the polarization state of the transmitted light transmitted through the other parts to the substantially and approximately the same polarization state. CONSTITUTION:Incident light 102 transmits a 1st polarizing plate 3 and becomes linearly polarized light 103 when the natural light 102 is made incident to the polarizing plate 3. The linearly polarized light 103 becomes the elliptically polarized light rays 105, 105' which depend on the cell thickness of a region 501 and a region 501' respectively by transmitting the region 501 of the desired cell thickness of the liquid crystal cell 5 and the region 501' of the cell thickness different from the desired cell thickness. The respective polarization states are made nearly the same by the means for further changing these polarization states, by which the unequal colors of the display colors are eliminated. An optical delay plate 10 is so disposed that nearly the same polarization states of the incident light rays 110 and 110' on the 2nd polarizing plate 4 are attained. The color differences of the regions 501, 501' of the different cell thicknesses are eliminated when the light rays pass the 2nd polarizing plate 4. The display having the no unequal colors is thus obtd.

Title: Water quality monitoring meter
Inventor: OGAWA YUJI
IPC: G08B21/00
Filed: 1990-06-05
Abstract: PURPOSE:To monitor the operation state of a water processor stably for a long period even when a battery is used as its power source by turning on a flow switch when a flow of fluid is detected and feeding the voltage from the battery to a transmitting receiving circuit part intermittently. CONSTITUTION:When processed water is supplied by opening a valve, the flow switch 1 turns on and the voltage of the power source battery 2 is applied to a timer circuit K and an alarm holding circuit N. The circuit K outputs one pulse for a time (t) (e.g. 1 second) at intervals of a time T to drive the circuit for transmission and reception for the measurement of the water quality monitor meter. This driving is controlled by a transistor (TR) 3 for power supply intermittence. When the measured value of the water quality exceeds a set value set in an alarm setting circuit G, an alarm signal is outputted to the alarm holding circuit N. The circuit N holds the alarm signal and turns on a TR H for buzzer driving to drive an alarm buzzer I until a next driving pulse is inputted the time T later. When the alarming is quitted, a buzzer stop switch J is only turned off. Thus, the life of the battery 2 is prolonged greatly.

Filed: 1983-08-11
Abstract: PURPOSE:To improve noise characteristics and a current amplification factor of a low current region by making concentration in the surface section of an emit- ter region lower than that in an internal section. CONSTITUTION:In a vertical type NPN transistor, a P type base region 2 and an N type emitter region 3 in the P type base region 2 are each formed to the main surface of an N type substrate 1, and a P type additional region 4, which is shallower than said N<+> type emitter diffusion region 3 and concentration thereof is lower than the region 3 and which is diffused and formed so as to coat the whole surface of the N<+> type diffusion region, is shaped. Accordingly, since electrons are difficult to be implanted to the base region 2 from the emitter region 3 in the surface of the substrate, the recombination of implanted electrons is reduced, a high current amplification factor is obtained even by low currents, and the fluctuation of currents is minimized by the effect of charges in an oxide film and noise characteristics are improved.

Title: Digital convergence correction device
Inventor: WATANABE KATSUMI
IPC: H04N9/28
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To suppress power consumption low in convergence correction by making current flow from a high power supply voltage to a convergence coil in the case the input correction waveform of digital convergence is steeply changed and making the current flow from a low power supply voltage to the convergence coil in the case the input correction waveform is gently changed. SOLUTION: The digital convergence input correction waveform and a voltage detection value by a resistor 5 for the current flowing to the convergence coil 4 are compared, and when the difference is large, the high power supply voltage is required so as to make the current flowing to the convergence coil 4 follow it. On the other hand, when the difference is small, since a response is easy as well, the low power supply voltage is sufficient. The high and low power supply voltages are switched with a threshold value as a reference. In such a manner, the response of the digital convergence is raised in the case the input correction waveform is steeply changed and a high voltage is not unnecessarily applied in the case it is gently changed.

Abstract: PROBLEM TO BE SOLVED: To suppress generation of migration by forming the rear surface electrode of a semiconductor of such a metallic material as not ionized easily even under presence of water. SOLUTION: A diode chip 1 comprises a semiconductor layer 6, an electrode 7 formed on the surface of the semiconductor layer 6, an electrode 8 formed on the rear surface of the semiconductor layer 6, and a barrier layer 9 formed between the semiconductor layer 6 and the rear surface electrode 8. The rear surface electrode 8 is formed by depositing Au, Al, Pt, or the like, on the rear surface of the semiconductor layer 6. Alternatively, an Au alloy, e.g. Au-Si, may be deposited and these metals and alloys feature that they are not ionized easily even under presence of water. Consequently, even if a reverse voltage is applied under a state where dews are formed in a glass shield diode, the metals and alloys are not ionized like Ag and thereby short circuit due to migration can be prevented between anode and cathode.
