Title: Organic material treating device
Inventor: FURUYA YOSHIYA
IPC: B09B3/00
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To efficiently decompose an organic material by measuring the change of current value of a PTC planer heat generator arranged in a treating vessel to detect the water content of a material to be treated, which is housed in the treating vessel. SOLUTION: The PTC planer heat generator 12 provided in the main body drum 2 of the treating vessel 1 is rapidly increased in the temp. after current is applied and the material to be treated in the treating vessel 1 is heated. The lower the temp. of the material to be treated, the more the heat is transferred, and at this time, the temp. rising of the PTC planer heat generator 12 itself becomes slow. When the temp. of the material to be treated is high, the heat is hardly transferred and the temp. rising of the PTC planer heat generator 12 becomes rapid. That is, the material to be treated is low in the temp. and high in the water content when the temp. rising of the heat generator 12 itself is slow and, when the temp. rising is fast, the water content of the material to be treated is decreased. The dropping of the current value becomes slow with the slow temp. rising of the PTC planer heat generator 12 and rapid with the fast temp. rising. Then, the water content of the material to be treated is fixed basing on the current value of the PTC planer heat generator 12.

Title: Wafer measuring instrument
Inventor: NAMIKI YOSHIJI
IPC: G01N21/88
Filed: 1985-10-31
Abstract: PURPOSE:To measure the patterns of wafers with a variety of widths by using a liquid crystal having a light transmitting region with a variable width and making the widths of the slit openings substantially continuously change. CONSTITUTION:A slit plate is constituted by a liquid crystal shutter 31 having a plurality of opposite pairs of stripe-shaped transparent electrodes 31a, 31a...31n, 31n arranged on the upper and lower surfaces of the shutter 31. The electrodes 31n are formed in a stripewise configuration with 12mum wide electrodes arranged at predetermined speaces, for example, at 3mum spaces while sandwiching a 3mum thick insulating layer 33. Since those electrodes 31n allow light to pass therethrough when a voltage is applied from a driving circuit, by sequentially increasing the number of electrodese to which the voltage is applied, the widths of the slit openings are accordingly increased. By sequentially stopping the applications of the voltage to the electrodes, the widths of the slit openings are accordingly decreased. The width of the openings in this case, when the arranging width of the electrodes are made, for example, 300mum, can be made continuous within the range of approximately 0mum-300mum. When the weidth of the insulating layer between the electrodes can not be reduced, two laminated liquid crystal shutters 35 and 37 can be used.

Title: Production of electric resistant body of nitride thin film
Inventor: UEMA TSUNEAKI
IPC: C23C14/06
Filed: 1986-10-14
Abstract: PURPOSE:To obtain the titled resistant body with almost zero thermal coefficient of electric resistance and having a desired specific resistance, by adjusting the total flow rate of mixed gas of gaseous N2 and inert gas when the nitride film is formed. CONSTITUTION:Air is exhausted from a reaction chamber 1 in the state of heating a base plate and a pre-sputtering operation is performed by closing a rotary shutter 6 and allowing only inert gas such as Ar to flow in. Then the thin film is formed by setting the flow rates of Ar and gaseous N2 each at the specified flow rate, allowing glow discharge to cause and opening the rotary shutter. The thickness of the film, its specific resistance and its thermal coefficient of resistance (TCR) are measured and a crystal structure of the film is analyzed with a part of sample by X-ray diffraction method. The total flow rate of gas is made larger for forming the thin film with higher specific resistance and is made smaller for forming the thin film with lower specific resistance in the state of zero TCR.

Title: Mechanical non-stage transmission
Inventor: FUKAYA SUEO
IPC: F16H15/52
Filed: 1989-09-21
Abstract: PURPOSE:To prevent the inclination of an epicyclic friction wheel and improve the transmission torque by providing disc springs for energizing mutually opposed press plate and moving ring in the direction pressed into contact with the epicyclic friction wheel, of press plates and moving rings provided in such a manner as to be axially movable and incapable of rotating. CONSTITUTION:When a regulator device 34 is operated to radially (downward in the drawing) move the shaft 26 of epicyclic friction wheels 251, 252 and an epicyclic metal 27, the contact position between a moving ring 30 and the friction wheels 251, 252 is moved downward, the radius of the contact position between the friction wheels 251, 252 and the ring is increased, and the radius of the contact position between the friction wheels 251, 252 and a sun friction wheel and press plate 23 is reduced. Thus, the revolving speed of the friction wheels 251, 252 becomes higher, increasing the output rotation from an output shaft 29. In this case, even if a force in the direction inclining the friction wheels 251, 252 acts on the frictional surfaces of these wheels, the inclinations are absorbed by the respective axial movements of the ring 30 pressed by a disc spring 32 and the press plate 23 pressed by a disc spring 24.

Title: Fuel cell power generating system
Inventor: AKAO YOSHIZO
IPC: G05F1/67
Filed: 1988-09-30
Abstract: PURPOSE:To prevent a fuel cell from being rapidly changed and to attain operation even without the fuel cell by parallelly connecting an inverter, a transformer, an auxiliary power converter and the transformer and controlling the operation of the auxiliary power converter in correspondence to the output of a direct current voltage detector. CONSTITUTION:A switch 6b is already closed before the rapid change of an effective power commanding value is generated. Then, an auxiliary power converter 9 goes to inverter operation to output effective power which is smaller than a prescribed value. When the converter 9 receives a detecting signal from a direct current voltage detector 10, the output of the converter 9 is changed from the effective power value, which is before the signal is received, to the prescribed effective power value. When the 25% of a fuel cell current value is defined as the prescribed value of the effective power, a fuel cell current goes to be the current of 25% at least even when wide fluctuation is generated in the effective power commanding value. Accordingly, the fluctuation of a fuel cell voltage can be suppressed enough smaller than a system not having the converter 9. When the converter 9 is operated with a rectifier operating mode, the converter can be used instead of a direct current power source and an inverter 4 can be adjusted and operated without using the fuel cell.
