Title: Search method in optical disk player
Inventor: YOKOTA HACHIRO
IPC: G11B7/085
Filed: 1988-02-09
Abstract: PURPOSE:To shorten a time to be needed for a search such as the heading of music, etc., by suppressing a number to read absolute time information and the number of track jumps to be necessarily minimum. CONSTITUTION:When a pick-up 3 is moved to a position P1, which is near a target position Pb, by thread-sending, the absolute time of the position P1 is read from a CD 1. Then, when the track jump is executed only by a prescribed track number 10, the absolute time of a position P2 is read again from the CD 1. Next, a unit moving time per track is calculated and when an M-track jump is executed to the pick-up 3, the pick-up 3 achieves the target position Pb. Thus, the number of the track jumps after the thread-sending operation is caused to be slightly twice. Then, the time to be needed for the music search is shortened and the heading of the music is widely shortened.

Abstract: 1504361 Heat exchanger; waste gas steam generation SCHMIDT'SCHE HEISSDAMPF GmbH 14 March 1975 [15 March 1974] 10759/75 Headings F4A and F4S A heat exchanger contains substantially straight double-pipes 1 each comprising an outer tube 4 and an inner tube 5 connected at their ends to a headers 6 and 6<SP>1</SP> in such manner that the outer tubes 4 communicate with the interiors of the headers, whereas the inner tubes 5 pass through the headers. The outer tubes 4 have thickened walls 9 at their ends at their junctions with the headers. Cracked gases to be cooled (produced in pyrolytic cracking processes) are passed through the inner tubes 5 from a head 2 to a head 3. Cooling water is passed through the outer tubes 4 from the headers 6 and leaves as steam through headers 6<SP>1</SP>. The cooling water enters headers 6 through feed pipes (not shown) and the steam leaves through steam pipes (not shown) leaving each of the headers 6<SP>1</SP>. The headers 6 are arranged in a row and the headers 6<SP>1</SP> are arranged in a row. (Alternatively the headers could be pipe rings). The headers of each row are welded together, e.g. at 13, and thus form gas-tight pipe end plates. The cross-section of the headers may be oval (as shown), round or polygonal.

Filed: 1988-02-12
Abstract: PURPOSE:To improve the luminous intensity in the forward direction and the luminance of emitting surface, and obtain a thin type light emitting diode and an LED surface light emission source, by using a constitution wherein the lights emitted from a plurality of light emitting elements are reflected by a reflecting surface on a recessed surface, and then radiated outward. CONSTITUTION:Electric power is supplied to light emitting elements 1a, 1b, by circuit patterns 3, 4 and wires 5a, 5b formed on a transparent glass substrate 2, and the light emitting elements 1a, 1b emit light. The lights emitted from the light emitting elements 1a, 1b are reflected in the direction almost parallel to the center axis of a reflecting mirror 6, by a reflecting surface 6a, and then radiated outward. As a result, the lights emitted by the light emitting elements 1a, 1b can be effectively utilized. While the area of light emitting surface is kept identical with the conventional one, the luminous intensity in the forward direction and the luminance of emitting surface are increased, and the irregularity of luminance can be eliminated. Further, since the reflecting surface 6a is arranged on the light emitting surface side of the light emitting elements 1a, 1b so as to face them, extremely thin type one can be formed.

IPC: F15B11/16
Filed: 1982-02-26
Abstract: PURPOSE:To raise the concurrent operability of plural actuators by supplying pressure oil from an auxiliary pump to actuators of a high working pressure. CONSTITUTION:When the slewing switch valve 7 of a multiple switch valve 4 and an arm switch valve 8 are concurrently operated, pressure oil from the main pump 1 is supplied through a parallel high-pressure pathway 10 to the arm switch valve 8 of lower working pressure, but pressure oil from an auxiliary pump 3 is supplied through a check valve 17 to a neutral pathway 9 upstream of the slewing switch valve. Thus, the shortage of pressure oil from the parallel high-pressure pathway 10 is compensated and sufficient amounts of pressure oil is obtained in the slewing actuators. Also, the slewing capability can be kept constant even when arm operation and slewing operation are concurrently made.

Title: Rotary transmission system for synchronous motors
Inventor: ITOU NOBUHIRO
IPC: H02K7/10
Filed: 1978-03-16
Abstract: PURPOSE: To facilitate frequency modification by changing the specific rotary speed change ratio from the first axis of rotation to the second axis of rotation at the primary frequency power use through the mutual exchange of rotor elements at the secondary frequency power use and almost equalizing the r.p.m. of the second axis of rotation.  
     CONSTITUTION: The first axis of rotation 2 and the second axis of rotation 3 are removably mounted on the gears 4 and 5, respectively. When the power of the primary frequency (f) is used, the rotary speed change ratio from the first axis of rotation 2 to the second axis of rotation 3 is assumed to be (f 2  / f 1 ) 1/2  and when that of the secondary frequency f 2  is used, it is assumed to be (f 1  / f 2 ) 1/2  by replacing the gears 4 and 5. The number of teeth n 1  and n 2  for the gears 4 and 5 is assigned so that the r.p.m. of the second axis of rotation 3 can be almost equalized. For example, supposed that the frequencies f 1  = 50 Hz and f 2  = 60 Hz, the change in the r.p.m. of the axis second axis of rotation is reduced as small as much without practical hindrance at the number of teeth of n 1  = 23,  n 2  = 21, n 1  = 241, n 2  = 220, and n 1  = 505, n 2  = 461. As a result, the r.p.m. of the second axis of rotation 3 is kept constant in eigher 50 Hz or 60 Hz frequency power.
