IPC: H02P9/30
Filed: 1992-06-12
Abstract: PURPOSE:To provide an AC generator for a vehicle which can output an output current by a simple circuit configuration irrespective of the number of turns of an armature coil even in the case of a predetermined rotational speed or less for starting power generation. CONSTITUTION:An AC generator for a vehicle comprises a diode bridge 3 of first rectifying means, a voltage regulator 5, a diode array 7 of second rectifying means, and a switching element 9. The bridge 3 rectifies an AC current from the generator 1, and supplies its DC component to a battery 21.a load 23 through output terminal 19a, 19b. A short-circuiting current flows to armature coils 1ua, 1va, 1wa, etc., during ON period of the element 9. In this case, the short-circuiting current is controlled unidirectionally by the array 7. Thus, power is stored in armature coils 1ub, 1vb, 1wb, etc. Stored power is output through the bridge 3 in superposition on generated voltages of the coils 1ua, 1va, 1wa during OFF period of the element 9.

Filed: 1979-11-26
Abstract: PURPOSE: To produce a post-crosslinkable polyol polymer completely free from carboxylic acids, by saponifying a specified precopolymer of diallyl phthalate.  
     CONSTITUTION: A prepolymer is obtained by copolymerizing diallyl phthalate with a comonomer such as diallyl oxalate, diallyl malate, diallyl tartarate or a mixture thereof, in a molar ratio of about 1:0.2W5, in the presence of a radical polymerization initiator such as benzoyl peroxide, stopping the reaction prior to the formation of gel, and removing the unreacted material. Then, a solid polyol polymer is obtained by dissolving the prepolymer into an organic solvent such as benzene, adding to the solution an alkali in an amount larger than that required for the complete saponification of the comonomer, reacting the mixture at below 50°C to effect saponification, neutralizing and water-washing the saponificate, and drying the product.

Title: Color display device and light receiving device
Inventor: KENMOCHI KATSUE
IPC: G02F1/1335
Filed: 1990-06-12
Abstract: PURPOSE:To light-receive/display a natural color as it is by a compact and simple device by controlling polarizing and transmitting characteristics without using any dyestuff such as dye or the like. CONSTITUTION:Light emitted from a white light source 7 is reflected toward a step 18 to be interfered after hitting a reflection face 15 of a projecting sphery when the light is made transmissive by electrically controlling cells 10 and 11. The difference of an optical path is generated between the beams reflected on the higher and lower faces of the step 18 and since the light having a wavelength equal to the optical path difference is strengthened each other and the light deviated from the wavelength is weakened each other, for the light passing through a glass board 21, the light in a wavelength area corresponding to the dimension of the step 18 is observed much stronger. Therefore, a released face 22 of the glass board 21 is observed in the color.

Inventor: OKAMOTO NOBUHIRO
IPC: H04N5/7826
Filed: 1987-06-19
Abstract: PURPOSE:To surely sample a horizontal synchronizing signal by generating a synchronizing gate pulse having a wider gate width till stabilization of the motor rotative speed after the start of a driving motor. CONSTITUTION:In the transitional period after the start of the driving motor till stabilization of the rotative speed, a gate pulse generating circuit 2 and a gate selecting circuit 8 generate a set pulse SP ahead of a prescribed set pulse generation time in the stable period of motor control and generate a reset pulse RP behind a prescribed reset pulse generation time. A gate generating circuit 3 is reset by the input of the pulse SP and is reset by the input of the pulse RP to generate a synchronizing gate pulse SG whose gate width is wider than a prescribed gate width in the stable period. Consequently, even if the cycle of a reproduced horizontal synchronizing signal PH is varied in the transitional period of motor control, the horizontal synchronizing signal is sampled if the variation width is within the gate width of the pulse SG.

Title: Quartz oscillation type electronic timepiece
Inventor: SAKURAI YASUHIRO
IPC: G04C10/00
Filed: 1979-11-30
Abstract: PURPOSE: To realize a long lifetime for a power supply battery, by driving an oscillation part and others of the CMOS.IC via a resistance having a voltage dependence property.  
     CONSTITUTION: The voltage of the power supply battery 25 is divided by the resistance 27 having such voltage dependence property in that the distance is 10μm or  less between the serial resistance 26 having no voltage depedence and two pieces of diffusion resistances, and then drives the MOS.IC oscillation part 21 and others connected to the dividing part 22 via the voltage produced across the resistance 27. The resistance value of the resistance 27 increases as the voltage of the battery 25 lowers down. Thus the proportion of the voltage change across the resistance 27 is made very small compared with the proportion of voltage reduction of the battery 25. Accordingly, the virtual limited voltage value which minimizes the current flowing to the MOS transistor at the part 21 is reduced, and thus the lifetime of the battery is increased in comparison with such a case as the limit value voltage is set at rather a high level owing to a reduction of the power consumption.
