Patent JP-S6312909-A (JP)
Title: Distance detector
Inventor: SATO SHUNICHI
IPC: G02B7/28
Filed: 1986-07-03
Abstract: PURPOSE:To obtain a device which performs distance detection with high accuracy by converging light from a target body, arranging two parallel flat plates slantingly to the optical axis and causing astigmatism, and detecting the sectional shape of the luminous flux. CONSTITUTION:Laser luminous flux emitted by a laser light source is converged by a condenser lens 3 to be radiated on an information recording medium S serving as the target body. This light is reflected by the medium S and guided to the parallel flat plates 5 and 6 through the lens 3 and a beam splitter 4. Those flat plates 5 and 6 are of the same size and slant in the opposite direction, so comatic aberrations cancel each other and the coherence of the luminous flux is not lost, but their effects of astigmatism are added together. Then a photodetector 7 is positioned where the section of luminous flux causing astigmatism is circular when the lens 3 and medium S are at prescribed distance from each other. The section varies with the distance, so the state of the distance between the lens S and medium S is detected from the output of the detector 7.

Title: Rf signal correction circuit
Inventor: MAEDA AKIYOSHI
IPC: G11B20/02
Filed: 1985-07-17
Abstract: PURPOSE:To perform sufficient corrections with a simple structure and make the correction possible even in case of dust sticking to a sensor, by detecting the signal amplitude of a RF signal and using this detection signal to correct the level reduction of the high band frequency component of the RF signal. CONSTITUTION:The amplitude of the RF signal is detected by an amplitude detecting circuit 2, and the detection signal corresponding to the amplitude level is applied to a high band frequency varying circuit 3. This circuit 3 raises the level of the high band frequency component of the RF signal in accordance with the detection signal and outputs a corrected RF signal to an output terminal 4.

Title: Lens driving mechanism
Inventor: HIRAI TOSHIAKI
IPC: G02B7/04
Filed: 1994-07-08
Abstract: PURPOSE:To obtain a highly accurate driving result with a simple constitution and to prevent lens driving force amount from being unnecessarily increased by setting an elastic member in a state where it presses a lens frame in one direction within only a first extending area. CONSTITUTION:The lens frame 1 is driven to a focusing position by a transmitting member 6 connected to a driving pin 5. The extending amount of the lens frame 1 is made small in the case where the distance to an object is long. At this time, a spring 4 is brought into contact with the spring receiving part 7 of the lens frame 1, and presses the lens frame 1 to the extending direction of a helicoid on an optical axis. Consequently, since the spring 4 eliminates clearance effect exerted by the helicoid, focusing accuracy of the lens barrel is improved. On the other hand, if the distance to the object is short, the lens frame 1 is extended, and the extended amount is larger than that in long distance photographing. At this time, the length of the spring 4 is a natural length, and is brought into non-contact with the spring receiving part 7 of the lens frame 1. Consequently, the lens is not required to resist the pressing fore of a pressing member, so that the driving amount of the lens can be minimized.

Abstract: PURPOSE:To perform the insertion or deletion of a character string by providing a KANA(Japanese syllabary) buffer to store a KANA character to which Roman letter/KANA conversion is applied, a KANA attribute buffer to store attribute whether or not a character whether or not a character is a leading character in a KANA character string, and a cursor that can be designated in one character unit. CONSTITUTION:The character string to which the Roman letter/KANA conversion is applied is stored in the KANA buffer 104, and also, a Roman letter that is the origin of it is stored in a Roman letter buffer 106, and the Roman letter string when the Roman letter/KANA conversion is applied, and a flag to display whether or not the character is the leading character in the character string in one character unit in a correspondent KANA character string are stored in the KANA attribute buffers 105, 107. The attribute representing the leading character is used to keep consistency in correspondence of the cursor positions of the Roman letter and the KANA character. Thereby, it is possible to move the cursor in one character unit to every position, and to perform the deletion and insertion of the character at that position.

Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To simplify a combining device and stabilize productivity by producing a longitudinally sliced veneer for an original sheet and a longitudinally sliced veneer for a core sheet in the order of combination at a back stage of production. SOLUTION: This longitudinal slicing machine feeds veneers one by one to trim both ends of the veneer in parallel with its fiber direction in a direction in which the fiber runs and scarf-cuts the front edge part and the rear edge part of the veneer to join the scarfed parts with an adhesive and further, cuts the joined veneers to the fixed length by specified dimensions to laminate the cut veneers. In this case, a calculation is delayed or started depending upon a signal for cutting to the fixed length to be connected by a previously set fixed length cutting device 11.  Further, the total length of the veneers which are present between the fixed length cutting device 11 and a veneer feeder 4 is detected to determine that the total length reaches the fixed length size, based on a detection signal to be connected by a veneer detector 15 installed on the outlet lateral part of the veneer feeder 4. This operating sequence is performed by a switching control circuit 14 to select between the operations by a feeder 3 for an original sheet and by a feeder 4 for a core. Thus the original sheet 1 and the core 2 are selectively fed from the feeders 3, 4 to selectively cut the original plate 3 and the core 2 into longitudinally sliced veneers 8c for the original sheet which become the front sheet or the back sheet and a longitudinally sliced veneer 8c for the core which becomes the core 2.

CONSTITUTION:A partition plate 4 having a window 5 and a shielding plate 7 made of a stainless steel or the like and used to open and close the window 5 by means of an external magnetic field, is fused to the center of a stem 3 before the thus obtained body is installed in an outer tube 1. Next, electrodes 9a and 9b are installed on either side of the partition plate 4 to form a discharge path passing through the internal top area of the ounter tube 1. Then the inner surface of the outer tube 1 excluding the top area is coated with a phosphor 2. After that, both surfaces of the partition plate 4 are coated with a phosphor 6, thereby constituting a small fluorescent lamp. As a result, after the window 5 is opened by moving the shielding plate 7 by means of an external magnetic field, a controlled state of ignition can be achieved through a short discharge path formed owing to electric discharge performed through the window 5.
