Title: Synthesizing method of plzt thin film
Inventor: OKADA MASARU
IPC: C23C16/40
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To surely synthesize a thin film of good quality without intrusion of foreign matters even in a large area by MOCVD method by using an org. metal source material containing Pb, La, Zr and Ti which does not cause nuclear producing reaction in a gas phase and which exhibits excellent step coverage. SOLUTION: When a PLZT thin film is synthesized by MOCVD method, an org. metal source material described below is used as the source material. The org. metal source material contains Pb, La, Zr, Ti which constitute the thin film, does not cause nuclear producing reaction in a gas phase and has about >=80% step coverage. As for the org. metal source material, for example, Pb(C2 H5 )4 , La(C11 H19 O2 )3 , Zr(C11 H19 O2 )4 and Ti(C11 H1 9O2 )2 (OCH3 )2 are preferably used as the Pb source, La source, Zr source and Ti source, respectively. The synthesis is carried out under conditions of >=500 deg.C, preferably 500 to about 700 deg.C, under <=5 Torr, preferably <=1 Torr pressure. Thereby, a PLZT thin film with excellent characteristics can be obtd. without post-annealing.

Title: Ventilator with filter
Inventor: YASUTOMI KENZO
IPC: F24F7/013
Filed: 1993-10-29
Abstract: PURPOSE:To extend the life of a filler of a ventilator without restraining the wind pressure resistance during operation of the ventilator by a method wherein a filter element of the filter has a larger oily dirt retaining capacity at the low,cr part than at the upper part. CONSTITUTION:When a ventilator 1 is operated with a filter 4 in use, oily dirt caused by soot, etc., begins to attach on the whole surface of the filter 4 at first, but after a long term operation, the amount of oily dirt caught by a filter element 6 exceeds the limit of the dirt retaining capacity of the filter 4 and oily dirt begins to fall down. This phenomenon is more remarkable at time filter lower part 6a, however, the filter lower part 6a has a double-layered filter element 6 to increase the oily dirt retaining capacity, so that oily dirt falling down from the upper part can be retained by the lower part 6a. Therefore, oily dirt does not fall down from the filter 4 unless the amount of oily dirt exceeds the oily dirt retaining capacity of the lower part 6a, resulting in an extension of the life of the filter 4. In addition, if the lower part 6a is provided with a multiple-layered construction, the retaining capacity of oil falling down from the upper part can be increased.

Title: Liquid-level measuring method of heat radiating type level sensor
Inventor: ISHIKAWA NAOTO
IPC: G01F23/22
Filed: 1990-10-12
Abstract: PURPOSE:To improve measuring accuracy by displaying a level by the estimation based on the past data. CONSTITUTION:A vehicle speed sensor 6 for detecting the accelerating and decelerating states of a vehicle and a steering-angle sensor 7 for detecting the steering angle of a steering wheel are connected to a CPU 4. The CPU 4 measures a level at an ordinary time and displays the level. In the running mode, the running distance is computed based on the data obtained from the sensor 6 and the elapsed time. The amount of fuel consumption within the elapsed time is computed based on the preset running fuel consumption. Then, the value is converted into the amount of the level. The amount is subtracted from the above described measured level value, and the estimated value is computed and outputted to a display part 5. In the running mode, the amount of consumption based on the preset running fuel consumption is computed without using the present detected value in this way. The amount is subtracted from the actually measured value, and the result is displayed as the estimated liquid level.

Then, by a sweep controller 6, the mechanical arm current 17 and a set value 16 are compared with each other, and when the mechanical arm current 17 is lower, then sweep direction command 7 is set so that driving frequency 8 may be swept from the higher side to the lower side, and when the mechanical arm current 17 is higher, then the command 7 is set so that the frequency 8 may be swept from the lower side to the higher side. As a result, quick moving speed rise can be performed.

Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce the cost by focusing a plurality of images of an object on at least one image pickup element thereby performing the inspection process using the image picked up by means of a single camera. SOLUTION: A focusing system 6 is constituted of a plurality of plane mirrors 9 so that a plurality of different images 11 at the opening part of a container 1 to be inspected, e.g. a PET bottle, can be focused. The opening is illuminated by means of an illuminator 8 and a reflective plane 7 and the image at the opening part is subjected to multiple reflection on a plane mirror 9 so that a plurality (6, for example) of different images 11 at the opening part are focused together on the CCD element 10 in a single camera 5. Since many (n) images 11 are focused on a single element 10, (n) images 11 can be picked up using cameras 5 of less than (n) (normally, 1) and the cost can be reduced. Furthermore, since a plurality of images 11 can be arranged on the element 10, all images obtained electrically can be processed using a single camera 5.

Title: Card key system
Inventor: OKUSAKO KAZUTAKA
IPC: E05B49/00
Filed: 1992-10-12
Abstract: PURPOSE:To provide a card key which is hard to forge by installing optical filters that transmit light of predetermined wavelength bands in a card key and on a lower base, and enabling unlocking only if light received as the transmission wavelength bands of the two filters are coincident. CONSTITUTION:A switch is turned on by inserting into an inlet 5 a card key 6 having an optical filter 7a'-7f' which transmits light of a predetermined wavelength band, and then light rays of different wavelength ranges are emitted from a plurality of light-emitting elements 3a-3e. Next, the light rays reflected by a grating mirror 2 and transmitted through the filter 7a'-7f' of the card key 6 are filtered through an optical filter 7a-7f provided to a lower base 9. When the transmission wavelength bands of the two filters are the same, a light-receiving element provided to the lower base 9 receives the light rays and unlocking is done in accordance with that result. A card key which is hard to forge can thus be obtained.

Title: Cleaner device for belt conveyor with crosspiece
Inventor: KOYAMA TOMOYUKI
IPC: B65G15/44
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a cleaner device capable of sufficiently removing deposition sticking to a flat belt with crosspieces. SOLUTION: At a scratching location A, a scratching member 18 of a scraper main body 23 comes into contact with the surface of a flat belt 4 and deposition of the flat belt 4 is scratched by the scratching member 18. Subsequently, crosspieces 10 are abutted on the scratching member 18, thereby the scratching member 18 is pressed down and the scraper main body 23 oscillates from the scratching location A to a retreating location B. When the crosspiece 10 passes and is away from the scratching member 18 just after the oscillation, the scraper main body 23 returns from the retreating location B to the scratching location A by a weight 21. Thus, deposition on the surface of the flat belt 4 is continuously scratched by the scratching member 18 because the scratching member 18 comes into contact with the surface of the flat belt 4 again.

Title: Phase locked loop circuit
Inventor: YABUKI HIROYUKI
IPC: H03L7/10
Filed: 1986-11-17
Abstract: PURPOSE:To reduce the loop pull-in time at start without losing the characteristic at steady-state by connecting a diode in the forward polarity in parallel across a lag filter resistor being a component of a lag/lead filter and connecting a transistor (TR) in parallel across a lead filter resistor. CONSTITUTION:The cut-off frequency of a lag filter (comprising a resistor 115 and a capacitor 116) connected to the output of the phase comparator 104 is selected sufficiently lower than the comparison frequency of the phase comparator 104. Then the level of the AC component included in the output is decreased sufficiently smaller than the operating voltage of the TR 111 or the leading voltage of the diode 110 by the lag filter. The characteristic of the loop depends on the lag/lead filter (comprising resistors 107, 108 and a capacitor 109). In connecting the diode 110 to the resistor 107 in parallel, since a large voltage is generated at filter input terminals 112, 113 at start, the diode 110 is short-circuited, the cut-off frequency of the loop filter is increased and the loop is stabilized at a high speed. The TR 111 is connected in parallel with the resistor 108 to charge up the capacitor 109 at high speed at the start.
