IPC: C08F28/02
Filed: 1991-03-22
Abstract: PURPOSE:To obtain a plastic lens which produces neither bad odor nor anomalous odor during machining or polishing by incorporating a specified perfume into a specified highrefractive index resin. CONSTITUTION:A six-member ring ether compd. is incorporated as a perfume by 0.01-3.0wt.% into a copolymer of thiocarboxylic acid ester compd. expressed by the formula and monomers having two or more polymerizable groups which can make copolymers with atom or methyl group, R2 and R3 are same or different hydrogen atoms or alkyl groups, R4 is substd. or unsubstd. benzyl group, and m is >1 integer. When this resin compsn. is used for a plastic lens, it is preferable to add 20-500 pts.wt. of copolymerizable monomers to 100 pts.wt. of thiocarboxylic acid ester compd., e.g. benzyl thioethyl thiomethacrylate. It is especially preferable to use 1.8-cineole as the six-member ring ether compd. If the amt. of the perfume exceeds 3.0wt.%, the aroma becomes too severe, while if the amt. is <=0.01wt.%, bad odor or anomalous odor generates.

Title: Malfunction detecting circuit
Inventor: HATSUTORI TOSHIYUKI
IPC: G06F11/00
Filed: 1984-04-23
Abstract: PURPOSE:To minimize the increase of hardware and to detect the malfunction of a control circuit by providing a comparator which detects whether a flip-flop group is operated normally or not. CONSTITUTION:An up/down counter 8 indicates the number of control flip-flops, which are set to logical ''1'', out of control flip-flops 1-7. An adder 9 adds all of outputs S1-S7 of control flip-flops 1-7 and outputs the number of flip-flops which are set to logical ''1''. The output of the up/down counter 8 and the output of the adder 9 are inputted to a comparator 10, and the comparator 10 outputs the detection signal of logical ''1'' if they coincide with each other, but it outputs the detection signal of logical ''0'' if they do not coincide with each other. If there are troubles, the comparator 10 outputs the detection signal of ''0'' because the output of the up/down counter is ''1'' and that of the adder 9 is ''0'', and thus the troubles at some position of the control flip-flop group is detected.

Abstract: PURPOSE:To substantially reduce the wear of a piston itself by a method wherein in an engine having a cylinder and a sleeve forming a sliding surface of a seal while being installed with a relation of replacing an inner circumferential surface of an axial part of the cylinder, a diameter of a piston of area across an end part of the sleeve is formed smaller than that of another part of it. CONSTITUTION:A piston 7a is formed such that an area 31 across an end part 30 of a sleeve 14 at its axial position is formed to have a smaller diameter than that of another area over a range of l1 (provided, l1>l). That is, when a diameter of another area of the piston 7a is is a range of 30 to 40mm, a diameter of the area 31 is formed to have a small diameter of about 0.5mm reduction. An expansion engine 4a constructed as above may perform an operation similar to that of the prior art. Even if there is a slight step at an interface part between an inner surface of the first cylinder 10 and an inner surface of a sleeve 14 due to a non-coincidence between an axis of the first cylinder 10 and an axis of the sleeve 14, the piston 7a, i.e., the area 31 does not contact with this step part.

IPC: B60L9/18
Filed: 1980-06-18
Abstract: PURPOSE: To improve the torque balance of an electric motor vehicle by introducing a constant current control by a current pattern to the control region of a constant voltage variable frequency.  
     CONSTITUTION: A subtractor 10 applies a deviation between a current pattern responsive to the rotating speed of an induction motor 5 outputted from a pattern generator 13 and the actual current to a pulse width modulator 8. An adder 9 adds a slip frequency command fS and the rotating speed of the motor 5, and applies the addition to the modulator 8. A subtractor 11 adds a deviation between the pattern from a pattern generator 13 and the actual current to the frequency fS in the control region of constant voltage variable frequency. In this manner, the current control in the control region of constant voltage variable frequency is performed by controlling the slip frequency, and large torque unbalance between controlling units can be avoided.

Title: Gas introducing device in mass spectrometer
Inventor: NAKAGAWA KAZUO
IPC: H01J49/04
Filed: 1994-04-20
Abstract: PURPOSE:To effectively analyze a trace quantity of gas adsorbed to, stored in or sealed in a raw material with simple constitution by simple operation by arranging a means to crush a vacuum line and a sample and a means to introduce an eliminating gas component to a mass spectrometer. CONSTITUTION:When a gas component sealed inside a small electric lamp S is analyzed, before the lamp S is crushed, air inside a sample chamber 10 is exhaused in a high vacuum. That is, a high vacuum valve 12 and a variable valve 22 are closed, and an opening-closing valve is opened, and a rotary pump is driven, and air inside the chamber 10 is exhausted in a high vacuum. When the lamp S of a sample is crushed by operating a crushing means 34 after it is exhaused in a high vacuum, gas in the lamp S is diffused in the chamber 10. Next, the diffused gas is introduced to a mass spectromenter through the valve 22, and is analyzed and measured. Thereby, since a trace quantity of gas sample in a high vacuum is directly introduced to the mass spectrometer and can be measured, a mass spectrum from which mixing of a background signal is avoided can be obtained.

Abstract: PURPOSE:To prevent deterioration in coherent integration even when the stagger system for each pulse is used by predicting the phase change of a reception video according to a pulse period (PRI) value and a target speed for performing phase. CONSTITUTION:An antenna 3 of a pulse Doppler radar radiates a highfrequency pulse from a transmitter 2 in synchronizm with the trigger of a timing generator 1 and at the same time receives reflection echoes from a target, etc. The reflection echoes are sent to a receiver 5 via a transmission/reception switcher 4 and then are converted by an A/D converter 6 after amplification and detection processing, etc. A variable sample coherent integrator 7 performs phase compensation corresponding to the PRI and then performs coherent integration. Namely, the integrator 7 predicts the phase change of a target reception video according to the stagger for each pulse according to the PRI value and a target speed and then achieves coherent integration by compensating phase. The output signal of the integrator 7 is processed by a target information processor 8, thus obtaining information such as the presence or absence of a target, its position, and its speed.

Title: Grain packaging bag, packaged grain, and method for fusionsealing
Inventor: SAIGA NOBUO
IPC: B65D30/10
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve daeration with constant air-permeability always secured and also to prevent rainwater or insects from entering a bag by forming a vent hole of such a size that grain may not leak with an unsealed part left for allowing difference between film lengths on both sides on a part of a fusion- sealed part. SOLUTION: When two films 3 wherein at least an internal face is made of thermoplastic synthetic resin is heat-compressed to fusion-seal, a thin rod-like metallic spacer is interposed between the surface and rear films 3, heat compression is performed from both sides by a pressurizing plate including a heater and an elastic pressurizing plate such as silicone rubber, and a vent part 5 is formed on a part of a fusion-sealed part 4 with an unsealed portion with one of the films swelling outward left. Thus even if the packaging bag 1 is filled with grain 2 and stretching force works lengthwise to the fusion-sealed part 4, excessive air in the bag can be reliably exhausted without crushing the vent part 5. In addition, since film ends 6 out of the fusion-seal 4 are normally in tight contact with each other, entrance rainwater or the like can be prevented.
