Title: Variable selection circuit for uhf band
Inventor: HASHIMOTO KAZUAKI
IPC: H03J5/24
Filed: 1988-03-31
Abstract: PURPOSE:To cut an interference wave near the image frequency which are supplied to a mixing circuit and to realize the effective conversion of frequencies by adding a coupling loop using a crosslinking polymer material wire to a conventional circuit. CONSTITUTION:A PVC wire 31 is soldered 32 to a secondary side inductor 14 together with the PVC wires 33 and 34 set along the inductors 13 and 14, respectively. Thus a coupling loop 35 is obtained. The position of the wire 31 is freely controlled as shown by an arrow head. Thus a trap 37 is formed at a point near the image frequency within a pass band of a variable selection circuit to catch the interference frequency owing to use of the loop 35. Then the frequency position of the trap 37 is changed with control of the position of the wire 31. Thus the frequency characteristics are changed as shown by the dotted lines with addition of the loop 35. Thus it is possible to satisfactorily attenuate the interference wave to the image frequency.

Title: Preparation of preservable food
Inventor: ONO TAKUJI
IPC: B65B25/00
Filed: 1992-02-27
Abstract: PURPOSE:To prevent the degradation of taste and the discoloration of a food which cannot be used together with a deoxidizer or a food necessary to keep its softness and shape and to obtain a preservable food having prolonged relishable period. CONSTITUTION:The present preparation process is composed of a filling step, an exhaustion step, a filling and sealing step and a heat-treatment step. A food is filled in a container having high gas-barrierness such as a bag in the filling step and air is exhausted from the filled container in the exhaustion step. In the gas-filling and sealing step, the exhausted container is sealed after introducing an inert gas into the container to keep the food from contact with oxygen by the gas-barrier container. Subsequently, the food is heat-treated together with the sealed container in the heat-treatment step to improve the thermal sterilization effect on the content.

Title: Apparatus for measuring degree of polarization
Inventor: KURODA KENJI
IPC: G01J4/00
Filed: 1987-03-31
Abstract: PURPOSE:To obtain a highly accurate degree-of-polarization measuring apparatus capable of easily calculating a degree of polarization at a high speed, by rotating the polarization plane of a Faraday rotor and calculating the degree of polarization from the max. and min. receiving quantities of light to be measured at this time. CONSTITUTION:When light Q to be measured is projected on a Faraday rotor 12 and passes through the Faraday rotor 12 and a detector 10 to be incident to a light detector 11, the detector 11 outputs the light receiving quantity detection signal proportional to the receiving quantity of light. At this time, an exciting part 14 sends out an exciting control signal rotating the polarization plane of the rotor 12 within a range of 0-360 deg. to a magnetic field generator 13. By this method, the polarization plane of the rotor 13 rotates from 0-360 deg.. During the rotation of said polarization plane, a quantity-of-light judge part 15 receives the light receiving quantity detection signal from the detector 11 to judge the max. receiving quantity Imax of light and the min. receiving quantity Imin of light and sends out both receiving quantities of light to a degree-of-polarization output part 16. The output part 16 calculates a degree of polarization by the operation of said receiving quantities of light to send out the same to a display means.

Filed: 1979-06-19
Abstract: PURPOSE: To make the constutition of quick-return mechanism simple by controlling the start of quick return by way of a motor which runs according to shutter release.  
     CONSTITUTION: When the release signal by the depression of a release button is applied, a motor 10 is run by the specified amount by a motor control circuit 19 and the detention by a movable mirror operating cam 13 is released, by which the starting of the quick-return mechanism is controlled to oscillate the movable mirror operating lever 14 by the accumulating force of a spring 15, thereby causing the movable mirror to make quick return. Upon completion of exposure, the energizing force of the spring 15 to be exerted to the lever 14 is accumulated by the motor 10 and cam 13 in a similar manner. Hence, the need for any electromagnetic mechanism and the like is eliminated and the constitution of the quick-return device becomes simple.

Title: Semiconductor integrated circuit
Inventor: SAWADA KAZUHIRO
IPC: H03K17/00
Filed: 1987-03-30
Abstract: PURPOSE:To prevent malfunction from being caused even if two input signals rise at the same time by changing the potential difference level of an output signal is response to the potential difference between nodes. CONSTITUTION:The potential at nodes N1, N2 is decreased and increased from an intermediate level respectively and its potential difference exceeds a threshold voltage of a transistor (TR) Tn1 at a time t2, then the potential at the nose N1' is decreased. The potential of an output signal Vout1 starts increasing and the potential at the node N1' goes to an L level (at time t3) and the potential of the output signal Vout1 goes to an H level. ON the other hand, the potential of the node N2' is unchanged and the output signal Vout2 remains N level. Since the potential level of outputs signals Vout1, Vout2 is changed in response to the potential difference between the nodes N1 and N2 in such a way, the output signals Vout1, Vout2 are not affected by the intermediate potential, thereby preventing malfunction.

Abstract: PURPOSE:To increase the convergence of lines of magnetic force on a magnetic control blade in a scraper shape by providing the control blade opposite between the N and S poles of a magnet fixed in a sleeve. CONSTITUTION:A developer holding member, e.g. sleeve 2 is arranged nearby a photosensitive body. The control blade 6 is provided above the sleeve 2 in such a scraper shape that its front end part is slanted toward the rotation- directional dowstream side of the sleeve 2 and belt in the tangential direction to the surface of the sleeve. The front end part of the blade 6 is formed of a magnetic body. The fixed magnetic poles N1 and S1 are arranged in the sleeve 2 opposite each other across the blade 6. In this constitution, the pole S1 functions as a leading-in pole for lines of magnetic force form the pole N1 to increase the convergence of the lines of magnetic force from the pole N1 on the blade 6. Consequently, the relatively weak magnetic poles prevent magnetic particles from leaking out of a developer container.

Filed: 1986-04-03
Abstract: PURPOSE:To make it possible that halogen gas generated at the time of charge is not adsorbed but released upward and halogen gas supplied at the time of discharge reacts sufficiently with an electrolyte, by providing small hydrophilic portions and small water-repellent portions together in a mixed state in a cath ode. CONSTITUTION:In a cathode 4, small hydrophilic portions and small water- repellent portions are provided together in a mixed state so that halogen gas generated in the hydrophilic portions diffuses into the water-repellent portions and are not absorbed but released upward as bubbles at the time of charge, and halogen gas in a supplied electrolyte 2 diffuses into the water-repellent portions and sufficiently reacts with the electrolyte in the hydrophilic portions at the time of discharge. Since a large amount of Cl2 gas is generated due to an active catalytic reaction in the hydrophilic portions of the cathode 4, the quantity of the charge per unit time is ten and several times higher than a conventional halogen battery having a porous cathode made of graphite, so that the time for the charge is ten and several times shorter than the conven tional halogen battery and therefore very short.

Abstract: PURPOSE:To maintain steering stability by continuing a rear-wheel steering control means as stopping a slip factor control means, while providing a fail judging means for stopping both these slip factor and rear-wheel control means in response to the fail of a wheel speed signal of each driven wheel. CONSTITUTION:In a step S2, whether a wheel speed sensor 25 of each driving wheel fails or another wheel speed sensor of each driven wheel fails or not is examined. Sensors of both driving and driven wheels all fail, it means DW fail = TW fail =1, so that ABS/TRC control is stopped by a step S4, and combinedly rear-wheel steering control is also stopped by a step S6. In a step S8, it is set to ACTIVE = 0. As an ABS/TRC controller is stopped, ACTIVE being outputted by the controller is 0, and ACTIVE being outputted by a wheel speed operation/fail judging part is also 0, so at the side of a control unit U1, the ACTIVE is processed as 0.
