Title: Data cube control system
Inventor: KITAZAWA ATSUSHI
IPC: G06F12/00
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To reduce the number of combinations of aggregate results prepared by utilizing dependency between aggregation keys by referring to data cube definition information at the time of receiving an aggregation request from a user and extracting a proper aggregate result from an aggregation recording mechanism or generating a aggregate result from a data storing mechanism when necessary. SOLUTION: When a user specifies plural aggregation keys to be interesting objects and requests aggregation by an aggregation key specifying means 4, a data cube definition means 5 retrieves dependence relation 3 stored in a meta data storing mechanism 2 based on the aggregation request. Then the means 5 extracts the combination of plural aggregate results to be used for obtaining a summary or a detailed aggregate result and prepares data cube definition information 6 for defining a data cube. At the time of outputting the aggregation request from the user, an aggregation key referring means 10 refers to the information 6 and extracts a proper aggregate result from the mechanism 7 or generates a aggregate result from data stored in a data storing mechanism 1 if necessary.

Title: Circular magnet having characteristic distribution and manufacture thereof
Inventor: IWASAKI KATSUNORI
IPC: H01F1/08
Filed: 1991-06-27
Abstract: PURPOSE:To provide a circular magnet which has a high radial magnetic characteristic that has a magnetic anisotropy gradually increasing from the center towards an edge by making the most use of a warm-worked magnet and by improving the processing method. CONSTITUTION:An Nd13.8FebalCo7.5B6Ga1.25 alloy is manufactured by arc melting. This alloy is injected onto a single roll which rotates at the speed of 20m/sec. in an Ar atmosphere to make an unfixed form flake. Then, the obtained flake is roughly smashed into a green compact of 500mum or smaller and the green compact is compressed by hot pressing. After that, the green compact is subjected to warm plastic forming at 750 deg.C between an upper and a lower punch having a certain curvature to form a circular magnet. The radius of curvature of the lower punch is fixed, 65mm, while that of the upper punch is variable, 69, 65, or 61. The shape of the compact is so adjusted that the final expansion angle of the circular magnet may be fixed, 55 deg.C, and the maximum height of the center of the magnet may be uniform, 10mm. By this method, a circular magnet having an improved magnetic characteristic can be manufactured stably.

Title: Optical position detector
Inventor: NAKAMURA HIROBUMI
IPC: G01B11/02
Filed: 1982-09-10
Abstract: PURPOSE:To accomplish the position detection of submicron order with good reproducibility by providing a half mirror and an optical multiplier between an optical pickup and an optical positioning sensor. CONSTITUTION:The light beam emitted from a light source 10 is reflected by a reflection film 27 of a half mirror and is condensed onto a focal position detector 12 through a beam splitter 8. A lens driving circuit 15 moves a lens driving section 6 in accordance with the information on the deviation in the focal position so that the light beam stopped down by a stopping down lens 31 focuses on the reflection film 27 of the half mirror 1. The light beam transmitted through the mirror 1 forms an image on an optical position sensor 5 by an optical multiplier 2. The signal from the sensor 5 is conducted as a two-dimensional position signal to a main control section 20 which outputs the same as a position signal. Since the focus of the stopping down lens is automatically matched on the half mirror, the position detection in submicron order is accomplished with good reproducibility.

Title: Recording head for ink jet recorder
Inventor: HIROSE YOSHIHIKO
IPC: B41J2/19
Filed: 1984-07-27
Abstract: PURPOSE:To eliminate inconsistent supply of ink caused by buildup of air bubbles and insure stabilized ink supply, by locating an ink feed opening in a position which is lower in gravity direction than that of outlet of bubble discharge pipe which extends to relay solution chamber. CONSTITUTION:An ink feed opening 29 of an ink feed pipe 25 is located in a position which is lower by DELTAh in gravity direction than that of a bubble discharge opening 30 of a bubble discharge pipe 27 extending to a relay solution chamber 24. This arrangement causes ascending of bubbles 31 in the relay solution chamber 24 in a direction opposite to gravity in filled ink and naturally gathering near the bubble discharge opening 30. When ink pressurized by a pump is fed through a feed pipe 25, bubbles 31 are carried through the bubble discharge opening 30 and the bubble discharge pipe 27 together with ink in the relay solution chamber 24 and are discharged quite readily, leading to complete removal of bubbles in ink jet printing head. Thus clogging of recording head with bubbles is completely eliminated and recording with consistently high quality prints is accomplished.

Title: Controller of ac generator
Inventor: IWATANI SHIRO
IPC: H02J7/16
Filed: 1990-06-18
Abstract: PURPOSE:To prevent an accumulator from dying even after an engine is stopped for a long time and prevent thermal breakage of a voltage regulator when an AC generator stops by connecting a switching element to the field coil of the AC generator in series between both ends of a rectifier. CONSTITUTION:When a starter switch 6 is turned on, a starter 7 is energized by an accumulator 4 and rotated and an engine connected to the starter 7 is started. In this time, the voltage of the accumulator 4 is lower than the specified one to pass a current through a Zener diode 313, therefore, no current is passed through the Zener diode 313 and a transistor 314. Hence an accumulator current is passed through the base of a transistor 321 via a base current supplying resistor 315 and a diode 316 and passed through the transistor 321. As a result, the current is also passed through a power transistor 306, a field current is passed through a field coil 102, and an AC generator 1 begins to generate electricity and produces a generation signal as the engine starts.

Abstract: PROBLEM TO BE SOLVED: To improve the agitation mixing efficiency of a vibration type agitation mixing device and the heat exchanging efficiency of a heat exchange shearing a main part therewith. SOLUTION: A stirring body 15 is arranged in a casing 13 prodded with a flow passage 11 partitioned into multistage by parting plates 17 and when the stirring body 15 is vertically vibrated, turbulent flow is generated between the stirring body 15 and the parting plate 17 and the agitation mixing of a fluid fed to the casing 13 is carried out.
