Patent JP-S61159018-A (JP)
Title: Wick type liquid fuel burner
Inventor: KUMAZAWA KATSUYOSHI
IPC: F23D3/18
Filed: 1984-12-28
Abstract: PURPOSE:To enlarge the adjusting range of combustion by installing a fuel path which controls the heat input to a wick simply and largely by adjusting the flow rate and is made as one body with wick guide cylinder or contacting closely with the cylinder. CONSTITUTION:By start operation of a pump 74, a part of kerosene in fuel tank is drawn up and flows into a good heat conductive pipe 71 which contacts closely with the upper end of wick guide cylinder 27 by caulking in wound state around the cylinder and the wick guide cylinder 27 and the wick 34 are cooled by the pipe. Temp. of the cylinder 27 and the wick 34 are reduced corresponding to increase in flow rate of kerosene. When flow of kerosene is suddenly reduced to increase combustion, temp. of the wick 34 is not raised up suddenly with the aid of the wick guide cylinder 27 and a large upright flame does not take place. Further, during combustion, exposed wick is kept in such a constant level as ensuring sufficient air and complete combustion is enabled even in case of small combustion condition. Therefore, it is made possible to enlarge the adjusting range of combustion.

Title: Charge transfer device
Inventor: YAMADA TETSUO
IPC: H04N5/335
Filed: 1984-12-28
Abstract: PURPOSE:To transfer a small charge at high speed and to improve the transfer efficiency by providing a barrier part for becoming a barrier with respect to a carrier to be transferred along the direction for intersecting orthogonally with the charge transfer direction of the channel area of a semiconductor substrate by the prescribed interval. CONSTITUTION:The groups of codes 31-35, that of codes 36-39 and a code 40 denote the potentials of respective division channel areas 221-225 in a state without a built-in charge, barrier potentials corresponding to the barrier parts 241-244 and a signal charge to be transferred in a vertical direction on a paper, respectively. The implanted signal charge is built in the 1st division channel area 221. When a charge amount is increased to be below the same potential of the barrier potential 36, the charge flows in the 2nd area 222. As the charge amount increases further, it flows in the 3rd division channel area 223, whereby the width of a transfer path is widened together with the increase in the charge amount. Moreover the barrier parts 241-244 are provided so that an N-type impurity layer 22 is divided into five parts, and therefore the charge 40 partially located in the 1st area 221 or the 1st and 2nd areas 221 and 222 can be transferred even if the charge amount to be transferred is small, whereby the small charge can be transferred at the high speed.

Abstract: PURPOSE:To increase condensing accuracy on a track of beams and improve characteristics of recording and reproduction by having a plurality of oscillation regions which are driven independently one another and having at least two oscillation regions such as one region having a narrow width and other one having a broad width among a plurality of oscillation regions. CONSTITUTION:A semiconductor laser array has an AlGaAs active layer 3 as an oscillation region which is placed between n-type GaAs block layers 5 and is located directly below its array and is separated into three oscillation regions 8, 9, and 10 by separating grooves 11 and they are driven independently. Respective oscillation regions are limited by widths W of the n-type GaAs block layers 5, tor example, the oscillation regions 8 and 9 are used by light output 30mW under each width 4mum and then the oscillation region 10 is used by light output 3mW under its width 6mum. Each wave length in the case of light output 30 mw when they are used at the oscillation regions 8 and 9 is 7740Angstrom  and is almost equal to that in the case of light output 3mW when it is used at the oscillation region 10. Uniform wave lengths in movements are thus obtained at a semiconductor laser array.

Title: Torque converter for automatic transmission
Inventor: MORIGUCHI NAOKI
IPC: F16H41/26
Filed: 1990-10-16
Abstract: PURPOSE:To improve ratio of torque and efficiency of torque transmission by setting an bias angle of a pump impeller to an angular range of 3.3-9.3 deg. in the positive direction. CONSTITUTION:A bias angle of a pump impeller 13 is set to the inclination in the positive direction within the angular range of 3.3-9.3 deg., so that fluid having the infection of flow changed by a stator 15 flows smoothly into the pump impeller 13. As a result, pressure gradient in the direction orthogonal to the flow of fluid circulating in a torque converter 11 is reduced to restrain the secondary flow to the so-called main flow. Thus, the action of torque increase of the stator 15 is improved by few turbulence in the flow of the fluid, so that the ratio of torque and the efficience of torque transmission improved.

Abstract: PURPOSE:To eliminate shortage of elongation percentage accuracy in a low speed rolling by forming an elongation percentage computing elements into multistage composition to keep high elongation percentage detection accuracy and producing products having high elongation percentage accuracy by constantly and rapidly detecting elongation percentages in spite of high or low of a sheet passing speed. CONSTITUTION:When a sampling clock pulse generator 9 generates a 1st sampling pulse SP1, a 1st stage inlet side length measurement computing element 61 starts count of pulses generated by an inlet side roll pulse generator 4. When the counted number equals to a number corresponding to a given length L0, the element 61 outputs a coincide detection signal to a 1st stage elongation percentage computing element 71. A 1st stage outlet side length measurement computing element 81 starts count of pulses generated by an outlet side pulse generator 5 and outputs the number of counts to the element 71 at input of the 1st pulse SP1 to the element 81. The element 71 calculates an elongation percentage epsilon1 based on a counting value L1 of the element 81 at the time of generation of L0 length coincident detection signal from the element 61. By multiple composition of the same type of elongation percentage computing elements, products having high elongation percentage accuracy are obtained in spite of high or low sheet passing speed.
