Title: Radiation detector
Inventor: MINAGAWA YOSHINOBU
IPC: G01J5/34
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To detect radiation energy with no effect of the angular fixing direction by arranging two elements having same polarity on the opposite sides of central axis and arranging an element of different polarity having area equal to the total area of two element on the central axis. SOLUTION: Pyroelectric elements 1, 2 of same polarity having same area, for example, are arranged symmetrically at a predetermined interval on the opposite sides of a central axis (X axis). An element 3 having different polarity from the elements 1, 2 and area equal to the total area thereof is arranged on the X axis. The elements 1, 2 are connected in parallel with each other and connected in series with the element 3. Consequently, when the elements 1, 2 are subjected to radiation simultaneously, they are offset to produce no output. Since the heat source exhibits directivity characteristics as shown on the drawing, a sufficient output of 50% or more can be produced at the time of detecting a heat source regardless of the arriving direction of thermal radiation.  When the detector is used for detecting a heat mass, omnidirectional and non-directional detection can be realized while preventing erroneous detection due to external radiation from the atmosphere.

IPC: B65D77/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent a beverage pack from being clogged in a beverage discharge outlet and unavailable to be ejected. SOLUTION: Tea leaves 4 are enclosed in a tea pack and immersed in hot water in a pot to extract the nutriment of tea leaves 4, and a plurality of through-holes 5 are formed on a pack main body 1, and hole sealing sections 6 for preventing the leakage of a content are formed around the though-holes 5 of the pack main body 1. Even when the tea leaves are sucked around a suction hole and made to adhere thereon, tea can be discharged through the through-holes. As all surrounding seal sections are supported on a plurality of sites formed by the expansion of the pack, tea leaves are not likely to adhere closely all over the whole periphery of a beverage discharge outlet. The beverage can be discharged smoothly while the beverage pack is left enclosed in the pot.

Title: Manufacture of surface acoustic wave element
Inventor: MORISHITA SHIGEFUMI
IPC: H03H9/25
Filed: 1982-03-25
Abstract: PURPOSE:To cancel charges due to pyroelectric effect during manufacture or while an element is left as it is, by sort-circuiting interdigital electrodes through a thin wire before the element is contained in a case and fusing the short-circuiting thin wire after it is contained. CONSTITUTION:On a piezoelectric substrate 8 of LiTaO3, etc., an aluminum film is vapor-deposited uniformly, and resist is formed thereupon to form grating reflectors 11 and 12 and comb-shaped electrodes 9 and 10 by etching. In this case, the short-circuiting thin wire 13 is also formed between the comb-shaped electrodes 9 and 10 to form a short circuit between them. Consequently, the amount of dust stuck owing to pyroelectric effect during manufacturing is reduced greatly and the sticking of a little dust is not caused by charges, so it is removed easily by blowing air. After the package containing the element is sealed, a voltage lower than a discharge starting voltage is impressed to fuse the short-circuiting thin wire 13 by Joule heat.

Filed: 1988-02-29
Abstract: PURPOSE:To process signal transmission between a rotary magnetic head and a fixed part with simple constitution by superposing a control signal for the operating state of the rotary magnetic head on a signal for a power source. CONSTITUTION:A recording signal SR is supplied to first or second rotary magnetic head selectively, and also, a switching control signal CONT1 to draw out a reproducing signal SP obtained from the first or second rotary magnetic head selectively is modulated to a power source PW1 at a fixed part side K1, and is transmitted from the fixed part side K1 to a rotary drum side K2 with the power source PW1, and is demodulated at the rotary drum side K2. Since the switching control signal CONT1 to the power source PW1 is superposed and outputted from a signal processing circuit at the fixed part side K1 to the rotary magnetic heads 3A and 3B, the transmission of the recording signal SR and the reproducing signal SP between the rotary magnetic head and the signal processing circuit at the fixed part side K1 can be performed by the simple constitution.

Filed: 1986-03-04
Abstract: PURPOSE:To improve the moisture resistance of an amorphous silicon photosensitive body and to considerably prolong the service life by specifying the maximum height of the surface roughness of the photosensitive body. CONSTITUTION:An amorphous silicon photoconductive layer is formed on the surface of a support to obtain an amorphous silicon photosensitive body. At this time, the photoconductive layer is formed so that the maximum height of the surface roughness of the layer is restricted to <=300Angstrom . By the restriction, the surface area is reduced, so the exposed defects are reduced and the moisture resistance is extremely improved. The miximum height is preferably restricted to <=100Angstrom  so as to provide high resolution and durability. In case of <=50Angstrom  maximum height, the removal of a toner is facilitated and the printing resistance of the photosensitive body can be extremely improved.

Abstract: PURPOSE:To estimate the total stock of a silo when a cavity occurs by comparing the total stock calculated from a flow rate meter with that calculated from an ultrasonic level meter to detect a cavity in the grains and applying the history control to various information on occurrence of the cavity to learn the correlation among these information. CONSTITUTION:A silo stock control computer 5 receives the amounts of grains supplied into and discharged from a silo from the flow rate meters 1 and 2 and also receives the total stock of the silo from an ultrasonic level meter 3. Then the total stock calculated from the difference between the total amount of grains supplied and that discharged which are received from both meters 1 and 2 is compared with the total stock calculated based on the meter 3. When the difference between both total stocks is larger than a prescribed level, the coccurrence of a cavity is decided and the alarm information is displayed on a CRT screen. Meanwhile the computer 5 receives the brand of grains, the temperature, the water content, etc., from a field equipment controller 4 when the cavity occurs. Then the computer 5 applies the history control to various information when the cavity occurs and learns the correlation among these information to estimate the total stock of the silo and to display the total stock on the CRT screen when the cavity occurs.
