Patent JP-H10225043-A (JP)
Title: Motor and equipment provided with motor
Inventor: SUZUKI MASAHARU
IPC: H02K5/10
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To suppress a torque loss due to friction and thereby obtain a high sealing effect by installing a sealing member so that it can be rotated together with an output shaft and bringing one end face in the axis direction of the sealing member into contact with a housing. SOLUTION: At positions to correspond to spaces 7a, 7b of a housing 6a, 6b of an output shaft 4, sealing members 8a, 8b made of rubber material such as butyl rubber and chloroprene rubber are installed. Inner end faces in the axis direction of the sealing members 8a, 8b are brought into pressure contact with overhanging sections 6d, 6f of the housing 6a, 6b at proper pressure. An outer end face in the axis direction of the sealing member 8a is connected to an inner ring of a bering 5a constituted of a ball bearing and thereby the pressure of the inner end face in the axis direction of the sealing member 8a against the overhanging section 6d is properly set. The sealing members and the output shaft do not rotate ralatively and therefore a high sealing effect can be obtained.  Moreover, since an outer end face of the sealing member which has nothing to do with the sealing effect is away from an inner face of a cylindrical section, a torque loss due to friction can be suppressed.

Abstract: PURPOSE:To stabilize the outputs of generators by assembling a plurality of generating elements in a generator, inserting constant-current controllers between exciting windings and field windings and connecting between the constant current controllers. CONSTITUTION:Field windings 3a-3d and armature windings 4a-4c, 4a'-4c'... are wound on a stator core, and exciting windings Ex-A-Ex-B are wound. The outputs of the windings Ex-A, Ex-B are supplied to the windings 3a-3d through rectifiers D3, D4 and constant-current controllers 10, 11, which respectively control drive transistors Q1, Q3 in response to the deviation between the voltage for terminals of field current detecting resistors R1, R4 and a reference value. Further, a compensating ratio setting semifixed resistor R7 is inserted between the controllers 10 and 11. In this manner, the outputs of the generating elements can be highly stabilized, thereby preventing the magnetic influence to each other.

Title: Ceramic-base composite member and its production
Inventor: NAKAMURA TAKESHI
IPC: C04B35/565
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To produce a ceramic-base composite member capable of enhancing airtightness and thermal shock resistance. SOLUTION: Hybrid treatment consisting of CVI(chemical vapor impregnation) and PIP is adopted. A crack-free dense matrix is formed around ceramic fibers by CVI and a matrix is thoroughly impregnated and filled into the gaps by PIP to enhance airtightness. When the volume proportion of the matrix by the CVI is adjusted to about 5-80%, microcracks formed in the matrix by the PIP weakens the force of binding the ceramic fibers together, thus lowering the Young's modulus. Accordingly, the thermal stress is relieved and thermal shock resistance is enhanced.

Filed: 1987-01-30
Abstract: PURPOSE:To enable execution of ignition without excessive increase of C/A, by a method wherein the opening at the tip of a nozzle is placed on a sleeve to movable axially; for ignition, the opening at the tip of the nozzle is moved to the outside of a furnace, to form space part for ignition of pulverized coal in the sleeve. CONSTITUTION:Pulverized coal conveyed by means of primary air is injected through an injection nozzle 2 into a space part 7 partitioned by means of an air cutoff sleeve 3. In this case, a heat generating body 1 is in a stage of being heated to a temperature required for ignition of pulverized coal. With this state, the pulverized coal is ignited, and flame is formed in the space part 7. A mixture of pulverized coal and primary air temporarily resides in the space part 7 to substantially prevent C/A in the vicinity of the heat generating body 1 from lowering, and ignition of pulverized coal is ensured. After ignition is confirmed, a nozzle 8 for pulverized coal and primary air is moved to the furnace side in the direction of the center of the sleeve 3. Thereby, a solid content (char), being not burnt only by a primary air amount, is effectively mixed with air for combustion fed through a gap between an air box 5 and an air resistor 4 for combustion.

Title: Supercharger for engine
Inventor: TAJIMA SEIJI
IPC: F02B37/00
Filed: 1988-01-31
Abstract: PURPOSE:To achieve an optimal supercharged state corresponding to the octane value of fuel by enlarging the second state region having high supercharge capacity when the octane value of fuel is low. CONSTITUTION:Only a supercharger 22 is operated through changeover valves 35A, 35B under low rotation thus realizing a first state having low supercharge capacity. A supercharger 23 is also operated under high rotation thus realizing a second state having high supercharge capacity. When a sensor 74 detects knocking, a control unit 71 delays the angle of ignition timing, and judges that low octane value fuel is employed if the delay angle exceeds over a predetermined level. The control unit 71 selects a map set through enlargement of the second state region having high supercharge capacity, and controls the changeover valves 35A, 35B through an actuator 77 based on the map. By such arrangement, knocking can be prevented when low octane value fuel is employed with response and supercharge capacity being balanced properly.
