Title: Multispeed dynamotor
Inventor: YASUDA MASASHI
IPC: H02K19/32
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To improve utilization ratio of a magnetic flux by dividing all poles of a field of a dynamotor into a plurality of small poles, and providing coil terminals of the divided poles connectably in parallel with a field power source, thereby simplifying a structure of the dynamotor and a circuit configuration of switching the poles in the case of pole changing. SOLUTION: All poles are constituted of half coils, and connected in parallel with a slip ring for 14-pole machine and a slip ring for 12-pole machine in a predetermined pole array. Terminals 1, 3 and 2, 4 are allocated to both terminals of the coils of respective half-poles, and then connected to the rings according to polarities and use or non-use of the divided coils of the 14-pole and 12-pole machines. Thus, one type of the half-poles of the coils is sufficient. Since the pole changing of the 14-pole or 12-pole machine may be conducted according only to whether the ring is excited or not, a complicated circuit configuration is not necessary at all. Therefore, a two-speed dynamotor having high reliability can be realized even in the case of a large capacity machine.

Title: Production of waveguide type optical device
Inventor: KONO KENJI
IPC: G02B6/13
Filed: 1991-09-20
Abstract: PURPOSE:To shorten the absorption wavelength of excition and to decrease absorption losses by reducing the thickness of waveguides exclusive of a function part to the thickness smaller than the function part where two pieces of the optical waveguides are connected or disconnected in proximity. CONSTITUTION:An SiO2 mask 8 along the B-B' line of an n-InP substrate 6 is so formed as to attain h1=0.5mum, W1=2mum. An SiO2 mask 9 along an A-A' line is so formed as to attain h2=2mum, W1=5mum. A barrier layer (InGaAsP layer) of multiquantum wells is formed by a reduced pressure MOVPE method. A well layer (InGaAs layer) of multiquantum well is further formed on this barrier layer. Consequently, the growth speed is higher and the film thickness is larger in the function part where the mask height is large along the A-A' line than the region along the B-B' line where the mask height is small. Then, the absorption wavelength of the excition is shorter and the absorption losses decrease in the region of the waveguide part of the B-B' line.

Title: Byte circuit
Inventor: ITO MASAHIRO
IPC: H04L69/40
Filed: 1989-09-20
Abstract: PURPOSE:To detect all faults at once even when there is a module having two faults or more simultaneously by providing a gate selecting either a data of a transmission signal line or a reference data and a control circuit controlling the gate based on the result of discrimination from a comparator. CONSTITUTION:A reference data is outputted synchronously with a data coming from a transmission signal line 5. A comparator 2 compares the data for each bit and sends the result of discrimination to a control circuit 4. When the result of discrimination is 'No', the control circuit 4 sends a signal to a gate 3 to select the reference data 1. The reference data 1 is outputted to a transmission signal output line 6 through the operation. Thus, even if a module A detects a fault, since the data without error to a next-stage module B is outputted, even when a fault exists further in a stage after the module B, the faults are detected at once.

Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus which can prevent the amplification of an excited vertical vibration by a method wherein a flat link transmission mechanism is formed of a three-dimensional transmission mechanism and a special connection point follows a specific dimensional position within a very small tolerance on a constant plane by a parameter change method or the like. SOLUTION: A hinge 1 is set at a link point at a degree of freedom of 3, a hinge 2 is set at the central point of a crank at a degree of freedom of 2, and a hinge 4 between a connecting rod 1-5 and a crank 2-4 is set at a degree of freedom of 1 or higher. The total of the degree of freedom of a hinge with reference to a slide block 6 of a hinge 5 at the connecting rod 1-5 and of the degree of freedom of a hinge of the block 6 with reference to a fixed plane 9 is set at 3 or higher. A vertical hinge axial line 2-2 and a horizontal hinge axial line 3-3 which can be turned around the axial line are installed at the hinge 2. Thereby, the displacement in the horizontal direction of a crank end point 4 is converted into the twist of the vertical axial line 2-2 irrespective of its vertical displacement so as to act on the end point 8 of a lever 7.  In this manner, at the hinge 1, the transversal movement component of a running vehicle and the rotation component around the vertical axial line of the running vehicle are transmitted completely to the lever 7.

Abstract: PURPOSE: To prevent refrigerator fans from being locked by a method wherein each of the refrigerator fans can be separately controlled for its driving operation, and other non-driven fan is freely rotated by an air pressure of a driving fan when some fans are driven. CONSTITUTION: A refrigerating operation control part 33 separately controls a driving of each of a first refrigerator fan 18 and a second refrigerator fan 19. At a refrigeration chamber 4, only the first refrigerator fan 18 circulates cold air at a freezing chamber 3 while sucking it. During that period, as a temperature in the refrigerating chamber 4 is less than a refrigerating temperature, a thermostat switch 29 is turned off, the first refrigerator fan 18 is stopped, and in turn as the temperature is higher than the refrigerating temperature, the thermostat switch 29 is turned on to repeat its rotation again.  At this time, the second refrigerator fan 19 being kept at non-driving state is rotated in a reverse direction to that of the first refrigerator fan 18 under receiving an air pressure i.e., a negative pressure accompanied with the rotation of the first refrigerator fan 18 during the period in which the first refrigerator fan 18 is being rotated and further it may act to suck cold air within the refrigerator chamber 4 i0 opposition to the operation of the first refrigerator fan 18.

Title: Detergent concentration detector and washing machine using same
Inventor: TSUKADA KEIJI
IPC: B23Q11/10
Filed: 1989-09-20
Abstract: PURPOSE:To control the content of detergent in washing or processes of washing, rinsing or the like according to characteristics of aqueous solution which has the correlation with the detergent concentration in washing liquid and has no difference in the kinds of detergent used, by detecting the surface tension or boundary tension of the washing liquid in which the detergent is dissolved. CONSTITUTION:Washing liquid 2 in a washing tank 1 is sent when an electromagnetic valve 3a is opened, a piston 4 moves upward and a check valve 6a in a pressurizer 5 is opened. Next, when the piston 4 moves downward, a check valve 6b is opened to send the liquid 2 to a thin pipe 7 and liquid droplets 8 form in an opening part and drip successively. Then, a light path between a luminescent element LED 9 and light receiving element PD10 is interrupted to vary a light amount received in PD10. The varying cycle is an interval of dripping time which is measured by an optical measuring circuit and read by a washing machine control circuit 12. To correct a change in the characteristics of detectors, water containing no detergent used for washing is dripped next to the washing liquid and measured in the same manner as the washing liquid by opening an electromagnetic valve 3b. The result of the measurement of the washing liquid is corrected on the basis of such a result to control the washing and rinsing in the washing processes.
