Title: Three-axis type automatic transmission
Inventor: HATAYAMA KAZUMA
IPC: F16H3/091
Filed: 1991-05-08
Abstract: PURPOSE:To reduce the dimension of a three-axis type automatic transmission and improve versatility. CONSTITUTION:The fifth frictional engagement element C5 is installed on the second shaft CS at the center, and the first and second frictional engagement elements C1 and C2 and the third and fourth frictional engagement elements C3 and C4 are installed on the first and third shafts arranged on both the sides of the second shaft CS. When one between the first and third shafts MS and SS is used as input shaft, the second shaft CS operates as output shaft, while if one between the first and third shafts MS and SS is used as output shaft, the second shaft CS operates as input shaft. Since the first and second frictional engagement elements C1 and C2 and the third and fourth frictional engagement elements C3 and C4 are arranged in symmetrical form on both the sides of the second shaft CS, the dead space can be reduced, and a transmission case can be made small-sized. Further, since the position relation between the input shaft and output shaft can be changed, versatility can be improved.

IPC: H02P8/00
Filed: 1995-04-04
Abstract: PURPOSE: To suppress the heat generation of a motor by delaying the rise timing of a drive pulse given to the motor when the surface temperature of the motor is higher than a prescribed value and, while the rise time is delayed, switching the power supply voltage applied across the winding of the motor to a lower power supply voltage than that applied during normal drive time. CONSTITUTION: A voltage generated by dividing a reference voltage VREF through a thermister 3 and a resistor R3 is inputted to an A/D converter 2 and detects the surface temperature of a motor 4. When a signal line PHOLD becomes high, transistors Q5 and Q6 are turned on and a signal line VM supplies a drive voltage VM 12V. When the surface temperature of the motor 4 is >75 deg.C, the signal line VM actuates a timer 2. While the timer 2 is in operation, the signal line PHOLD becomes low and both transistor Q5 and Q6 are turned off. Then, the signal line VM supplies +3V to the motor 4.

Title: Liquid crystal display device
Inventor: KOMORI KAZUNORI
IPC: G02F1/136
Filed: 1990-04-19
Abstract: PURPOSE:To eliminate the reflected light from a light shielding film so that a sufficient black level can be generated by dispersing pigments into a resin thin film constituting the light shielding film to adjust the refractive index to 1 to 2. CONSTITUTION:This device is provided with the light shielding film constituted of the two layers consisting of the chromium thin film 5 and the resin thin film 4 which is dispersed with the pigments and has 1 to 2 refractive index or the three layers formed by sandwiching both sides of the chromium thin film 5 with the resin thin film 4. The light falling to the light shielding film is first partly reflected at the boundary on the surface of the resin thin film 4 and the balance is transmitted into the resin thin film 4. The boundary reflected light is drastically decreased and the greater part of the light falling onto the light shielding film can be taken in the resin thin film 4 if the refractive index of the resin thin film 4 is 1 to 2. Since the pigment are dispersed in the resin thin film 4, the light transmitted in the resin thin film 4 can be absorbed by these pigments. The sufficient black level is generated in this way.

Abstract: PURPOSE: To simplify the control system and to increase the throughput, by finishing the data transfer after waiting for the end of MS operation cycle in case of partial write-in and finishing immediately without waiting in case of full write-in.  
     CONSTITUTION: When the data transferred from the input and output device 1 to the main memory unit 4 via the channel 2 (consisting of data buffer 8 etc.) is partial write-in, the channel 2 executes the program of the flow (5) for a plurality of machine cycles and waits until the MS operation cycle including the confirmation of the check result of the data read out from the unit 2 to the register is finished, and if any error is detected 5 in the MS operation cycle, the micro programs (7) and (8) are executed and the failure information is shunted to a suitable location. On the other hand, in case of full write-in, at the MS operation cycle, no data readout check is made, then the flow (1) to (6) can be executed without waiting the end of MS operation cycle continuoutly to reduce the machine cycle.

Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To shorten time of automatic focus control by easily and reliably knowing the direction of a maximum focusing position when a lens exists in a position largely dislocated from the maximum focusing position by performing the automatic focus control by moving the lens on the basis of a degree of dispersion of a histogram acquired by a histogram acquiring process. SOLUTION: Monitoring of data on counting (a degree of dispersion of a histogram) (h) by a histogram measuring method of an input image signal is started by driving an image sensor 101. Next, a variation Δh of a degree of dispersion (h) of the histogram is judged by driving a focus motor 109 at a constant speed in the first direction. When the variation Δh is larger than 0, a lens 110 moves toward a maximum focusing position. When the variation Ah is not larger than 0, the driving direction of the focus motor 109 is reversed. When the variation Δh becomes smaller than 0, the lens 110 is regarded as passing through the maximum focusing position, and then, the lens is moved to the maximum focusing position.

Filed: 1985-05-17
Abstract: PURPOSE:To prevent an MOS-FET from damaging by an ON pulse voltage by connecting a diode in parallel with a coupling capacitor of the input side of a drive transformer so that the anode is connected with an input winding side. CONSTITUTION:In a drive circuit of an MOS-FET11 for operating ON and OFF a DC/DC converter, a diode 22 is connected in parallel with a coupling capacitor 18 connected in series with the input winding 19 of a drive transformer 1. The connecting polarity of the diode 22 is so decided that the anode is connected with the starting end of the winding 19. Thus, since the vibrating current of the transformer at the input side flows only on one direction, it can prevent the FET11 from damaging, and since the recoiling voltage between the gate and the source can be clamped, the efficiency of a converter can be improved.

Title: Gas shielded welding material for austenitic stainless steel
Inventor: FUJIMOTO ROKUROU
IPC: B23K35/30
Filed: 1981-07-03
Abstract: PURPOSE:To obtain the weld zones of a joint having high toughness at ultra-low temps., and having no defects such as blowholes, lack of fusion or the like by specifying the amts. of Al, Mg and Zr together with the amt. of Si in the basic components of ordinary austenitic stainless steel. CONSTITUTION:A titled welding material wherein Si is limited to <=0.3% and the amt. of Al, Mg, Zr alone or the total of >=2 kinds thereof is limited to 0.01- 1.5% in the basic components of ordinary austenitic stainless steel. Here, if the Si is limited, good low temp. toughness is obtained even without particularly severe limitation of the contents of impurities and ferrite. However, the spread of molten metal is degraded on account of such limitation and therefore, the Al, Mg, Zr are added. If the amt. of any of these alone or the total of >=2 kinds thereof is below the lower limit, the effect is low and the material is vulnerable to generation of defects. If it is in excess of the upper limit, the solidification state of the molten metal changes and the molten metal oxidizes, thus failing to provide spread. These elements are extremely effective in preventing the generation of blowholes in MIG welding.
