Title: Negative type resist material for far ultraviolet ray and formation of resist pattern by this material
Inventor: KUNISHI MITSUMASA
IPC: G03F7/038
Filed: 1981-03-13
Abstract: PURPOSE:To obtain a resist material having exceedingly high sensitivity and image resolution by preparing a negative type resist material for far UV rays of polynormal propyl alpha-chloroacrylate consisting of specific repetitive units. CONSTITUTION:A film is formed on a base material by using a negative type resist material for far UV rays consisting of polynormal propyl alpha-chloroacrylate having the repetitive units expressed by the formulaI. Thence, it is irradiated with far UV rays, and is then developed with a developing soln. consisting of carbon tetrachloride, whereby a resist pattern of negative type is formed. Since the said resist material has no sensitivity to visible light and UV light (>=260nM wavelength), it can be handled under ordinary light. Like with ordinary negative type resist materials, this resist material has higher sensitivity if it is made of the resist materials of higher mol. wts.

Abstract: PURPOSE:To remove unduely high open-circuit voltage of an organic electrolyte battery, by employing manganese dioxide treated with hydrogen. CONSTITUTION:The active oxygen contained in the surface of manganese dioxide is converted into water,  which is removed, by treating it with hydrogen. For instance, manganese dioxide undergoes heat treatment at  400 deg.C for 4hr to make the bound water and the adhering water or the manganese dioxide to be removed,  before the dehydrated manganese dioxide is mixed with both carbon black and a binding agent made of a  fluororesin and the mixture is compressed and molded, a positive electrode being made. The positive electrode is  put in a vacuum drier, thereby the pressure applied to the positive electrode being reduced. A mixture gas of  hydrogen with an inactive gas such as nitrogen or argon, is introduced in the vacuum drier, and the vocuum  drier is hermetically sealed, before the temperature of the drier is increased to 85 deg.C and the drier with increased  temperature is left for 3hr. After that, the positive electrode 1 undergoes vacuum drying overnight at a maintained temperature of 85 deg.C, thus a positive electrode 1 being prepared. Over 1.4cc at standard state (25 deg.C, 1  atmospheric pressure) of hydrogen is required for 1g manganese dioxide. Manganese dioxide alone may be  subjected to hydrogen treatment before it is molded. Consequently, the active oxygen contained in the surface of manganese dioxide can be removed, and a battery which does not provided any unduely high open-circuit  voltage over the normal voltage, 3.3V, can be obtained.

Title: Instrument for measuring physical property of liquid
Inventor: MURAMATSU HIROSHI
IPC: G01N11/16
Filed: 1989-02-15
Abstract: PURPOSE:To rapidly measure the viscosity of a small amt. of sample in a region of low frequencies and to make online measurement as well by using a piezoelectric ceramics oscillator. CONSTITUTION:The instrument consists of the piezoelectric ceramics oscillator 1, a cell 2 for holding liquid in the oscillator 1, an instrument 3 for measuring the characteristics of the oscillator 1 and a recorder or display device 4. The oscillator 1 is a device utilizing a piezoelectric effect and generates mechanical oscillation by impressing the voltage of the frequency near the resonance frequency. Although this oscillation is extremely slight, the oscillator 1 receives resistance from the liquid in the state in which the liquid is in contact therewith. The mechanical resistance is reflected in the resonance resistance of the oscillator 1 from the electro-mechanical conversion characteristic of the piezoelectric element. The physical properties occurring in the viscosity and density of the liquid can, therefore, by measured by determining the value of the resonance resistance of the oscillator 1 or a change in the resonance frequency thereof. The rapid measurement of the viscosity of a small amt. of the sample in the low-frequency region and the online measurement are possible in this way.

Filed: 1990-02-19
Abstract: PURPOSE:To prevent the light emitting efficiency of a phosphor from lowering at a low temperature and to accomplish measurement with high accuracy by providing a mechanism for heating the phosphor by a heater in a photodetector where the phosphor is used. CONSTITUTION:A photosensor part 4 is housed in a case 5 for packaging and the heater 6 buried in the wall surface of the case 5 is energized and heated, so that the phosphor 2 of the photosensor part 4 is heated to a constant temperature by the heater 6. Ordinarily, the phosphor 2 of the photosensor part 4 is heated to about 30 deg.C by the heater 6, but the heater 6 is turned off when an ambient temperature in measurement is >=30 deg.C. As a result, the sudden deterioration of the sensor because of the lowering of the light emitting efficiency of the phosphor 2 is not caused even though the ambient temperature in measurement is low (<=20 deg.C), thereby obtaining nearly uniform output values over a wide temperature range.

CONSTITUTION:A pulse generating circuit 2 generates a pulse at zero point of an input signal having the same phase as a main circuit current for input to delay pulse generating circuit 6. Meanwhile, a voltage sensor 3 detects control voltage of a vacuum valve of a vacuum circuit-breaker 8 and a temperature sensor 4 detects the temperature of an operational system of the circuit-breaker 8 and the detected signals are put in a time setting circuit 5.

The circuit 6 generates a driving pulse which is the pulse generated in the circuit 2 and delayed for the delayed time determined in the circuit 5 and provides it to the operational system of the circuit-breaker 8 through a tripping signal generating circuit 7. In this way, generation of regenerated arc and surge due to three phase simultaneous shutting is suppressed and because of no need of a surge protection apparatus, the cost of the circuit-breaker is lowered.
