Title: Permutation generator
Inventor: MASUBUCHI YOSHIO
IPC: G06F7/58
Filed: 1986-02-18
Abstract: PURPOSE:To easily and quickly generate all permutations of two values out of plural values by shifting circularly data in one stage among plural storage devices and shifting data in two stages there and transposing data of storage devices in the first and second stages. CONSTITUTION:If data (a), (b), (c), (d), and (e) are set to storage devices 11-15 respectively, the permutation of data (a) and (b) is outputted from devices 11 and 12 at the initial time. If a clock 101 is applied, data of devices 11 and 12 are interchanged because selectors 22 and 21.. select devices 11 and 12, and data (b), (a), (c), (d), and (e) are stored in devices 11-15 in order, and the permutation of data (b) and (a) is obtained. Since selectors 21-24 select storage devices in preceding stages by the next clock, data of devices 11-15 are shifted circularly. Data are shifted circularly in two stages after one circulation of shift, and thereafter, interchange between data of devices 11 and 12 and circular shift of data among devices 11-14 are performed alternately to obtain all permutations of two data out of dive data from devices 11 and 12.

Title: Automatic water supply pump device
Inventor: OKI HIDEO
IPC: F04D15/00
Filed: 1987-02-14
Abstract: PURPOSE:To decrease required power for a pump device so as to promote the saving of energy, by jointly using a main pump, which is started by a pressure detector, and an auxiliary pump which is started by a flow detector. CONSTITUTION:A level of water decreases lower in an overhead water tank 7, and if the level of water reaches a lower limit water level 21, a water level detector 8 operates releasing an automatic valve 6. Then decreasing a pressure lower in a pumping water main pipe 5 simultaneously allowing water in a pressure tank 14 to flow into the pumping water main pipe 5, a main pump 1 is started by turning on a pressure detector 15. And water in an intake water tank 11 is allowed to flow into the main pump 1 through a suction pipe 10 and into the overhead water tank 7. In this way, the level of water rises, and if it reaches an upper limit water level 22, a device, actuating the water level detector 8, closing the automatic valve 6, generating no flow of water in the pumping water main pipe 5 and actuating a flow detector 4, operates an auxiliary pump 17 to be started. Here the pump device, in which the main pump 1 is still in operation, generates a pressure, in which a delivery pressure of the auxiliary pump 17 is added to the delivery pressure of the main pump 1, in a delivery port of the auxiliary pump 17.

Title: Receiving data detector circuit in data transmission
Inventor: MATSUMOTO HIROYUKI
IPC: H04L7/033
Filed: 1978-03-22
Abstract: PURPOSE:To make it possible to use a good-transmission efficiency continuous synchronous system by detecting the polarity of receiving data and generating clocks which performs correctly sampling of receiving data on a basis of this detected polarity. CONSTITUTION:When the polarity of receiving data input 1 is changed, counter 10 is cleared forcedly, and output 13 becomes ''1'' for the purpose of setting forcedly flip-flop 12 which generates clocks for performing correctly sampling of receiving data. After that, output 13 of flip-flop 12 is changed from ''1'' to ''0'' at the logical center of receiving bits. Further, if receiving data bits have the same polarity, output 13 is changed from ''0'' to ''1'' at the boundary point of logical data bits. As a result, when receiving data input 1 is subjected to sampling at the trailing edge of output 13 of flip-flop 12, receiving data can be received correctly.

Abstract: PURPOSE:To try the improvement of adhesiveness and resolution by stacking a positive photosensitive film on the predetermined pattern of a negative photosensitive film with a film thickness of 5,000Angstrom  or less wherein the same pattern is formed. CONSTITUTION:An SiO2 layer 2 is provided on an Si substrate and a negative resist layer 13 is formed with a thickness of 5,000Angstrom or less to make a predetermined pattern.

Title: Device for projecting polarized image
Inventor: TAKEMURA YASUHIRO
IPC: G02F1/13
Filed: 1988-02-16
Abstract: PURPOSE:To improve the using efficiency of light quantity by arranging a polarized beam splitter in stead of a beam splitter. CONSTITUTION:One polarized beam splitter substitutes for the function of a polarizer for materializing the distribution of a polarizing state as a visual image and the function of a beam splitter for synthesizing the routes of a lighting system and an image forming system. When rays of light from a light source 1 are reflected or transmitted by/through the polarized beam splitter 18 and projected to an image medium such as a liquid crystal light valve 10, only one of S and P components is made incident upon the incident face of the polarized beam splitter 18. In case of the liquid crystal light valve 10 or the like, a polarizing face is rotated in accordance with a recorded image and only the component rotated its polarizing direction by 90 deg. is transmitted through the splitter 18 and reaches the image forming face of a screen or a photosensitive body through a projection lens 11. Consequently, the using efficiency of light quantity can be sharply improved.

Title: Lubricating structure in differential gear
Inventor: KUROYANAGI TOMOYA
IPC: F16H57/04
Filed: 1994-02-04
Abstract: PURPOSE:To ensure necessary and sufficient lubrication and to reduce power loss by providing an oil reservior at a place that is above a part to be lubricated and is on the forward side in the flowing direction of lubricating oil together with forming both an inflow port and an outflow port on the oil reservoir. CONSTITUTION:Since an inflow port 19 of an oil reservoir 15 is arranged on the forward side in a tangential direction of a ring gear 4, a part of lubricating oil 14, which was separated from the ring gear 4 because of centrifugal force, flows from this inflow port 19 into the oil reservoir 15. When the ring gear 4 enters high speed revolution exceeding a prescribed number of revolution, an inflow of the lubricating oil into the reservoir 15 becomes greater than an outflow of the lubricating oil from the oil reservoir 15. The outflow of the lubricating oil 14 from the oil reservoir 15, however, is kept almost constant because the opening area of each outflow port 20 or 21 is fixed. As a result, the lubricating oil 14 stays in the oil reservoir 15, corresponding to a difference between the inflow and the outflow. Consequently, a degree of stirring of the lubricating oil 14 by the ring gear 4 becomes low.

Title: Liquid crystal display control circuit
Inventor: MIHARA YASUTSUGU
IPC: G06F3/048
Filed: 1989-02-13
Abstract: PURPOSE:To eliminate the need for the processing time for the longitudinal- lateral conversion of display data by switching display data and a control signal by a row-column switching circuit and using a liquid crystal driver which is usable for both rows and columns. CONSTITUTION:When the row-column switching circuit 1-3 is placed in a longitudinally long display state by a host device, the switching circuit 1-3 assigns a liquid crystal driver 1-4 as a driver for row driving and liquid crystal drivers 1-5 and 1-6 as drivers for column driving. Consequently, a signal for row scanning is supplied by the driver 1-4 to a liquid crystal panel 1-7 and data for column scanning is supplied from the drivers 1-5 and 1-6 to the panel 1-7. When the switching circuit 1-3 is set in the longitudinally long display state, on the other hand, the switch circuit 1-3 assigns the driver 1-4 for column scanning and the drivers 1-5 and 1-6 for raw scanning.
