Title: Halogen-terminated liquid diene polymer and its production
Inventor: KURASHIGE YUUZOU
IPC: C08F36/04
Filed: 1984-06-11
Abstract: PURPOSE:The titled polymer which can form a cured product excellent in rubber elasticity and dynamic properties by reaction with an epoxy resin, an organic polyisocyanate compound, or the like, having a specified structural formula. CONSTITUTION:A halogen-terminated liquid diene polymer of formula I (wherein X is a halogen and n is 6-450). A conventional liquid diene polymer shows fluidity at room temperature and, when cured, it forms a three-dimensional network structure which shows physical properties like those of a vulcanized rubber. Though it is useful as a cross-linking agent for polymers containing a long- chain diamine or double bonds, the rubber elasticity or physical properties of such a cured product has been unsatisfactory. By the incorporation of terminal halogen atoms, the diene polymer can form a cured product excellent in rubber elasticity and dynamic properties and used as a resin modifier, raw material for a cured product or the like. This polymer is produced by reacting a hydroxyl group-terminated liquid diene polymer of formula II with a halogen compound.

Title: Front grille for outdoor machine of air conditioner
Inventor: AZUMA CHIAKI
IPC: F24F5/00
Filed: 1995-05-17
Abstract: PURPOSE: To suppress an interference sound and a burble sound to the utmost while suppressing an increase in an airflow resistance and thereby to lower a noise level of an outdoor machine by specifying a gap between supports of a grille and by shaping a section in the horizontal direction practically like an ellipse of which the ratio between the short and long axes and the length of the short axis are specified. CONSTITUTION: A dimension (c) of a gap between horizontal supports 9 each having a section shaped practically like an ellipse having a short axis (a) and a long axis (b) is made about 9mm which is the maximum dimension for preventing insertion of a finger in a testing method described in JIS C9612. In a grille prepared in this way, front-edge burble is hardly caused even when a flow from the front varies, and turbulence of the rear flow is also reduced. Besides, the mutual operation of the horizontal supports 9 produces an effect of suppressing the burble.  By shaping the horizontal section practically like an ellipse of which the ratio a/b between the short and long axes is 0.3-0.45 and the length of the short axis 4-9mm, besides, the grille wherein the burble is reduced with an increase in an airflow resistance suppressed and whereby a noise level of an outdoor machine is lowered is obtained.

Title: Base shifting device during opening of main roll of calender for magnetic tape
Inventor: MATSUMURA KATSUMA
IPC: B29C33/00
Filed: 1980-08-29
Abstract: PURPOSE:To cause no sag even in case each main roll is opened and made to pass through a raw fabric bas, by rotating both the cooling roll and touch roll with a little higher speed than a bottom roll by means of a stepless speed regulator, an electromagnetic clutch, etc. CONSTITUTION:Main rolls 1... are press-contacted with each other in the normal operation time, and electric conduction is given only to an electromagnetic clutch 22 to rotate a cooling roll 9. Thus a raw fabric base is taken up. In case a joint is caused in the raw fabric, the rolls 1... are separated from each other by a hydraulic cylinder. Then electric conduction is given to an electromagnetic clutch 34 to rotate a touch roll 15 via a Schmitt coupling 37. At the same time, the rolls 15 and 9 are press-contacted to each other via an air cylinder, and the raw fabric base is held between these rolles to feed the raw fabric base. The speed of rotation of both rolles 15 and 9 is set a little higher than that of a bottom roll 1. As a result, no sag is caused in the raw fabric base.

Title: Determining apparatus for completion of etching
Inventor: KOIZUMI TOORU
IPC: H01L21/306
Filed: 1982-07-09
Abstract: PURPOSE:To accurately determine the completion of etching by irradiating a detecting light to the back surface of photo mask in order to avoid an influence of etching liquid and by detecting the reflected light. CONSTITUTION:The detecting light 15 emitted from a light source 13 enters the inside of glass substrate 8 from the rear side of photo mask 7 and irradiates the rear surface of chromium film 9 formed at the surface of glass substrate 8. The rear surface of this chromium film 9 is polished like a mirror surface, the light 15 is totally reflected. The reflected light 16 almost irradiates a detector 14 passing the rought in accordance with the optical law. Therefore, the detector 14 outputs a highly detected value. Since the detecting light 15 is totally reflected by the rear surface of chromium film 9, it does not receive any influence of the etching liquid 4 on the front surface of chromium film 9. Therefore, an output waveform of the detector 14 receiving the totally reflected light 16 does not almost include any noise component. When the etching by the etchant 4 proceeds and the chromium film 9 is removed feom the surface of glass substrate 8, the detecting light 15 transmits the glass substrate 8.

Title: Multistage screen for granular body
Inventor: KUBOTA YOSHINOBU
IPC: B07B1/42
Filed: 1995-04-21
Abstract: PURPOSE: To stop a screen at a specified position when shaking is finished by providing the screen with a mechanism for electrically detecting the rotation of the rotary part of a movement changing part and a controller for stopping a drive source based on a detection signal from the detecting mechanism when the preset stop condition is established. CONSTITUTION: A position detecting signal from a position detector 23 is counted up by a counting means 36. When the count value reaches the preset frequency, a motor stop signal is transmitted to a motor control means 28 from a comparator means 37, the power supply to a motor 15 is stopped, a brake 30 is actuated, and the output shaft and turntable are stopped. Only an extremely short time is taken from the time when the position detecting signal is transmitted from the detector 23 through the detecting board of the turntable until the power supply to the motor 15 is stopped, and hence the moving distance of a frame after the position detection signal is transmitted from the detector 23 is neglected. Accordingly, the detecting board acts on the detector 23 in the final reciprocation of the frame, and the frame is stopped at a specified position.

IPC: G01L9/12
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a general purpose capacitive pressure sensor in which the effect of parasitic capacitance can be corrected with high accuracy at low cost. SOLUTION: A constant capacitor Cc having a reference capacitance is provided and the capacitance is detected by switching the constant capacitor and capacitors C1-Cn for pressure detection.

Abstract: PURPOSE:To compress the number of times of comparing among sort keys at searching and to shorten the sorting out time by deciding a search start position with a little number of times of comparing, and starting a final search from the top of the decided search start position. CONSTITUTION:A data input means 1 sets data to be sorted to a new data holding means 8, and hands over a control to a search start position deciding means 2 at any setting.
