Title: Rotary transformer
Inventor: TAKEUCHI TOSHIHIRO
IPC: H01F38/14
Filed: 1990-05-17
Abstract: PURPOSE:To realize a superior small-sized rotary transformer causing an unbalance of a net inductance by a method wherein a winding groove, which is magnetically divided by a short ring, is constructed in such a manner that a groove depth thereof is deep at a division end part and shallow at a central part. CONSTITUTION:Four signal transmission systems (hereinafter called CH) are constructed. Let the respective signal transmission systems called CH1, CH2, CH3, and CH4 in the order from the top system. The combination inductance of the CH2 and CH3 is large, and that of the CH1 and CH4 is small. In addition, the coupling coefficients of the CH2 and CH3 is large, and that of the CH1 and CH4 is small. Since the larger the combination inductances are, the larger the net inductance is, and also the larger the coupling coefficients are, the smaller the net inductance is. Judging from the above-mentioned contents, two factors are generally offset with respect to each other and the net inductance of all the four CHS can coincide with each other.

Abstract: PURPOSE:To obtain an accurate densitometer by distributing the amount of energy necessary for calculation of the density uniformly to an optical sensor. CONSTITUTION:Mirrors 15a-15c condense the reflecting light. to the corresponding optical sensors 18a-18c in accordance with the amount of energy for the respective color components detected by the sensors when the reflecting luminous flux is split into three.

Title: Flywheel device
Inventor: MIZOBUCHI SHOTARO
IPC: F16C17/04
Filed: 1986-06-05
Abstract: PURPOSE:To extremely lower a friction loss by applying a voltage to a piezo-electric element and deforming said piezoelectric element in the axial direction, and lifting up a rotary part. CONSTITUTION:When voltage is not applied, a piezo-electric element is contracted and upper and lower bearing boards 6, 7 are closely attached. When starting, as a defined voltage is applied to the piezo-electric element with a flywheel 14 being stopped, a rotary part is gradually lifted up to keep a gap at a defined interval. During operation, the gap is about 10-40mum when a working fluid is oil, 3-5mum in the case of water, and 1-2mum in the case of air. Accordingly, since a dynamic pressure thrust bearing supports a load by means of a dynamic pressure generated by a dynamic pressure generating groove, a friction loss is extremely low, also lowering a bearing loss at the time of accelerating.

Abstract: PURPOSE: To provide an automobile fuel consumption efficiency indicator of simple structure and low cost by a method wherein km/l is indicated by means of a distance integrating signal from a travelling distance meter and a consumption quantity signal from a fuel consumption meter.  
     CONSTITUTION: By means of the travelling distance meter 1 which rotates interlocking with a wheel 9 through a transmission means 12 such as a cable et al, a signal A being sent every unit distance e.g. 1km is entered in a computer 2 to perform an addition B.

And therewith, while travelling, km/l can be known, which can be useful for saving energy, thus, the lowering of engine efficiency can be known.

Abstract: PURPOSE:To prevent the leakage of gaseous ammonia and improve the workability for the jam or the like, by fastening tips of a soft seal member and a guide plate by a fastening member having a channel-shaped section. CONSTITUTION:The tip of the photosensitive paper exit side of a soft seal member 7 and the tip of a guide plate 9 are fastened by arms 12a and 12b of a  fastening member 12 having a channel-shaped section. Consequently, even if the  seal member 7 is deformed by heating due to the heat of a heater 4, waving phenomena are not generated to prevent the leakage of gaseous ammonia because the lower arm 12a of the fastening member 12 is adhered to the seal member 7. When the guide plate 9 is is turned to the outside for the jam, the seal member 7 is turned together, and it is unnecessary to position the member 7 again to improve the workability.

Title: Coater valve seat
Inventor: FUKUOKA MITSUHIRO
IPC: A45D34/04
Filed: 1989-05-22
Abstract: PURPOSE:To accurately prevent coating liq. leakage and keep coating liq. flow from a coater end favorable for coat application by providing a coater with a valve seat which is composed of moisture permeable material and so shaped as to obstruct coating liq. flow by contact with a valve body. CONSTITUTION:A valve seat 31, composed of moisture permeable material, permits the permeation of moisture therethrough but not the direct permeation of a coating liq. itself. When a coater 1 is not in use, a coating feed ball 6 in a receiving chamber 3a is urged into engagement with the valve seat 31 by a compression spring 11 so as not to permit the entry of the coating liq. from the receiving chamber 3a into a coating liq. retaining part 8. Since the moisture of the coating liq. is permeated through the valve seat 31, however, the viscosity of the coating liq. in the coating liq. retaining part 8 is not increased. When the coater 1 is shaken vertically, an abrupt reciprocal movement of the ball 6 in the receiving chamber 3a takes place against the compression spring 11 to force the coating liq. from the receiving chamber 3a into the coating liq. retaining part 8. At this time, as an end valve 4 obstructs an end opening 2e, the coating liq. is not scattered and, when a coating body 5 is forced against the part to be coated, it comes in contact with the coating liq. and a coat applicable state results.
