Title: Production of cacao flavor drink
Inventor: KOBAYASHI MASASHI
IPC: A23L2/38
Filed: 1990-06-14
Abstract: PURPOSE:To obtain a cacao flavor drink containing a fragrant component of characteristic cacao beans, having excellent shelf stability, by extracting a cacao composition from roasted and ground cacao beans by using an aqueous medium. CONSTITUTION:A cacao component is extracted from roasted and ground cacao beans by using an aqueous medium to give the objective drink. Cacao beans generally known as a raw material of chocolate, manufactured in Ecuador and Ghana, may be cited as the cacao beans used. Soluble solid content of cacao beans extracted is made preferably 5-20wt.% based on cacao beans. Namely, when the content is <5wt.%, extraction is insufficient and the drink has tendency of poor cacao flavor. On the contrary, when the content exceeds 20wt.%, the drink is liable to separate and precipitate.

Title: Image information processing method and digital image pickup device using it
Inventor: SATO KAZUYUKI
IPC: H04N19/00
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To improve the reduction in the compression efficiency by conducting prescribed processing for a period when a means attended with a motion is applied to a picked-up image so as to reduce an information amount of a digital video signal subject to coding processing. SOLUTION: During zooming based on a command from a zoom switch 7, a microcomputer 6 applies zoom control to a lens 1 and controls an amount of image information for a signal given to a coding circuit 5 to be reduced in advance through the processing such as filtering to a signal processing circuit 4. Furthermore, the microcomputer 6 controls the signal processing circuit 4 to minimize the limit of the image information amount through the processing such as filtering. Since the information amount 8 before coding that is compression-processed by the coding circuit 5 is reduced, even when the coding information amount is increased due to a motion of the picked-up image for the coding circuit 5, the increase in an information amount 9 after coding by the coding circuit 5 is suppressed.

Title: Shaft cooling apparatus
Inventor: DAIKO NOBUO
IPC: F04C29/02
Filed: 1981-10-02
Abstract: PURPOSE:To prevent back-flow of cooling liquid and to thereby enhance the cooling effect, by fitting a ring-like member at one end of a bore formed in a rotor shaft of a rotary compressor or the like along the length thereof, and feeding cooling liquid into the bore forcibly by the function of the ring-like member. CONSTITUTION:A bore 10 is formed in a rotor shaft 9 and a ring-like member 17 is fitted at one of the bore 10. In the inner peripheral surface of the ring-like member 17, there are formed slots 18 having respectively an inclined surface 18a which functions to impart thrust in the axial direction of the bore 10 (inwards of the bore 10) with rotation of the rotor shaft 9. A nozzle 15 is extended to the inside of the bore 10 through a central opening of the member 17, so as to feed cooling liquid into the bore 10. With such an arrangement, when the ring-like member 17 is turned together with the shaft 9, air existing near the member 17 is drawn into the bore 10 by the function of the slots 18, so that back-flow of cooling liquid fed into the bore 10 can be prevented.

Title: Analog switch circuit
Inventor: HAYAKAWA JUNJI
IPC: H01L27/04
Filed: 1995-06-22
Abstract: PURPOSE: To improve the surge breaking performance of an MOS analog switch while suppressing the extension of a chip area. CONSTITUTION: In an input side semiconductor area 201 of a transfer gate Q20 composed of an MOS transistor, when the input of a surge voltage in the direction to forward bias p-n junction between that area and a semiconductor area 203 just under a gate electrode is detected, at the time of surge voltage input, the semiconductor area (such as a P well area, for example), 203 just under the gate electrode is turned to a stray potential or let follow the potential of the input side semiconductor area 201. Thus, even when the high surge voltage is inputted to the input side semiconductor area 201, the forward bias of p-n connection between the input side semiconductor area 201 and the semiconductor area 203 just under the gate electrode is delayed and even when the p-n junction is transiently biased forward, that is immediately turned off.  As a result, a charge amount coming from the input side semiconductor area 201 to an output side semiconductor area 202 is reduced by a lateral parasitic transistor effect considerably in comparison with a conventional single step MOS analog switch circuit.

Abstract: PURPOSE:To replace in-system gas with inactive gas by removing oxygen from the air sucked in a system when the operation of a fuel cell is stopped by a contact reaction with a reforming catalyst in a reformer to form inactive gas and introducing the inactive gas into a fuel cell. CONSTITUTION:In a course of temperature falling after the operation of a fuel cell is stopped, a valve 13 of an air suction line 13 is opened. The amount of air corresponding to consumption of fuel gas remaining in a system and volume decrease caused by temperature decrease is introduced into the system from the outside through the air suction line 13. The air introduced into a reformer reactor 25 comes in contact with a reforming catalyst 24 which is activated state in the reformer 24, and oxygen in the air is removed by a contact reaction with the catalyst 24, and the air is converted into an inactive gas. The inactive gas is introduced into a fuel cell 1 through a fuel gas supply line 4. Thereby, in-system gas is replaced with the inactive gas.

Title: Safety device for rotary brush
Inventor: YAMAOKA SHIZUO
IPC: A47L9/04
Filed: 1988-06-27
Abstract: PURPOSE:To let a rotary brush be rotated only when a photo sensor senses darkness, and thereby prevent the hand of an operator from being caught in by forming plural sets of circuits using photo sensors each of which has a light receiving section on the lower surface of the suction port of the rotary brush. CONSTITUTION:In a sensor circuit, the logical product and exclusive logical product of an operation circuit 17 are so constituted that a relay switch 10 is closed when all of six photo sensors 6 sense darkness, but the relay switch 10 is opened then even one out of the sensors senses lightness. When a rotary brush is in operation, if the suction port of it is afloat from the floor, light directly comes in or reflected light from the floor comes in to any light receiving section 6 of the photo sensors so that the relay switch 10 is opened, and if the suction port is lowered down on the floor, the relay switch 10 is closed, the rotary brush thereby starts rotating. This constitution allows the rotary brush to be in operation only when the suction port comes in contact with the floor, thereby preventing hands and the like from being caught in the rotary brush at the time of cleaning.

The felt material 7 is shifted by an extent corresponding to one pitch of projecting stripes after a prescribed use time to use effectively all of the peripheral surface of the felt material 7. Thus, dirt and a toner stuck to the fixing roll 1 are scraped by projecting stripes 9, and the felt material is prevented from being rotated together with the roll 1 to perform surely the oil applying work.

The photographing conditions and the image processing method are set in each circuit to photograph the subject, based on the read setting value. It is confirmed as to whether the memory card is ejected, based on a detecting signal (55). If the memory card is not pulled out, a recording indication to a user is displayed in a display device (56).

Abstract: PURPOSE: To miniaturize bearings for a pump shaft, by providing surface seals over three portions between an inner peripheral wall of a cylinder and a circumference of a rotor so that radial load imposed on the rotor can be carried at surface seal parts.  
     CONSTITUTION: In a pump operation chamber B, a chamber moaving in the rotating direction of a vane 2 is decreased in volume with a rotation of the vane 2 and oil is discharged into housing discharge pressure chambers 8a and 9a from a discharge port 7. On the other hand, in the pump operation chamber B, a chamber in a rear side of rotation of the vane 2 is increased in volume and oil is sucked from a suction port 6a.

Accordingly, bearings 14 and 15 for a pump shaft interconnecting with the cylindrical rotor 1 can be miniaturized.
