Title: Demodulating method for optical signal and optical signal transmission/reception circuit
Inventor: OKUHORA AKIHIKO
IPC: H04B10/69
Filed: 1993-07-20
Abstract: PURPOSE:To reduce circuit scale and to reduce energy consumption by receiving a pair of optical pulse signals, which are generated from a pair of light emitting elements, at a pair of light receiving elements and performing trigger inputting to a flip-flop circuit. CONSTITUTION:A pair of optical pulse signals are generated by a pair of light emitting elements corresponding to the positive edge and negative edge of digital signals in a return zero form or a non-return zero form to be transmitted on the transmission side. On the reception side, a pair of these optical pulse signals are received by a pair of photodetectors PD 1 and PD 2, and the digital signals are demodulated by performing the trigger inputting of output signals from these photodetectors PD 1 and PD 2 to flip-flop circuits T11-T14, R1 and R2. Therefore, a threshold value operation is made possible by an optical pulse trigger input flip-flop operation, and an operation margin can be improved. Thus, an APC circuit on the transmission side and an AGC circuit on the reception side are unnecessitated.

Abstract: PURPOSE:To improve supply capacity of parts, by forming a spiral track having a transfer passage made gradually narrower in the upper part then in the bottom part to the internal peripheral surface of a bowl shaped vessel applied with torsional vibration to receive the parts. CONSTITUTION:If assumed (a) for a track width in a position located with the uppermost track T1, the width of a track T2 at in a position after turning a round downward from the position of the T1 is a+alpha. Hereafter, at every turning a round downward the width of the track is increased alpha by alpha. Parts are charged into a parts receiver vessel 3, if an electric current is conduced in a driving unit, the parts are applied with torsional vibration and transferred in the track, here the amplitude of the torsional vibration is increased the nearer it is to the upper part, and the density of the parts on the track becomes larger  the nearer it is to the upper part. Accordingly, the parts can be transferred by  effectively feeding in the width of each track part T1-T3.

Title: Data flow processor
Inventor: MIDORIKAWA HIROKO
IPC: G06F15/82
Filed: 1984-09-26
Abstract: PURPOSE:To improve the internal working factor of an internal flow device of a data flow processor by supplying with priority an input to a transfer table memory from an input queue memory only when this memory is filled. CONSTITUTION:A transfer table memory 2 supplies data from an input queue memory 9 or a processor 6. The data supplied to the memory 2 includes the data value, a memory address and a use flag showing the validity or invalidity of data. The memory 2 checks the use flags of the memory 9 and the processor 6 and fetches the data of '1'. When both flags are equal to '1', the priority is given to the processor 6. While the priority is given to the memory 9 when a forcible input is requested owing to a fact that the memory 9 is filled. Then both flags are invalidated if they are equal to '0'. This minimizes the interruption of the internal data processing owing to an external input.

Title: Semiconductor device and manufacture thereof
Inventor: FUJIMOTO KEIICHI
IPC: H01L23/50
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device of a semiconductor chip-side support structure which can increase its support strength. SOLUTION: Support leads 14 supportingly bonded to a semiconductor chip 12 at its sides with an adhesive 13 are bent at an angle of 50 to 70 degrees downwards in a side surface direction of the chip 12. Further, the chip 12 is supported at its sides to the support leads 14 being spaced therebetween by a distance corresponding to the adhesive. That is, the sides of the chip 12 do not abut directly against the support leads 14, but the chip 12 is sealed around its periphery with the sealing resin. Thus, even when the chip 12 and the leads 14 are subjected to a thermal stress, the resilience of the resin enables prevention of disconnection between the chip 12 and the leads 14, thus realizing an improved bonding strength.

Title: Position detector
Inventor: ABE HIROCHIKA
IPC: G01B7/00
Filed: 1986-08-29
Abstract: PURPOSE:To reduce malfunctioning by sampling an output voltage of a magnetoresistance effect element (MR element) synchronized with the operation of a magnetized medium when the voltage becomes stable. CONSTITUTION:When a relative position between an MR element 3 and a magnetized medium 1 is at step 0, a drive signal is sent to a driving circuit 11 from a control circuit 10 to move the medium 1 by one step. A sampling pulse is sent to a sampling circuit 7 from the circuit 10, synchronized with this drive signal, to sample a certain fraction of the DC voltage (MR output voltage). Subsequently, the medium 1 is moved by one step again to sample an MR output voltage synchronized with the movement thereof. The signal thus sampled is compared with the value sampled at the preceding step by a comparison circuit 9. When the level difference between these signals is below a specified value, with the judgement that the MR output remains unchanged, the medium 1 is moved by one step again. When it is above the specified value, with the judgement that the MR being changed, the medium 1 will not be moved. Thus, the detection of the position of magnetization is completed.

Title: Method for loading and reading of square picture
Inventor: JIIN SUUEI KAO
IPC: G11C8/00
Filed: 1994-08-26
Abstract: PURPOSE: To provide a method for executing transfer from a page buffer to a printer at high speed. CONSTITUTION: This method uses a memory for transferring a data word toward the direction of row or column in a burst mode. First of all, the memory is divided into two blocks 10 and 11, odd-numbered words are preserved in one block 11, and even-numbered words are preserved in the other block 10. Thus, the buffer can alternately read the word out of one memory while accessing the next address. When reading the even-numbered rows of images, since the sequence of continuous odd and even numbers is held, the continuous words are swapped at the interval of one column in source data so that the order of words can become 1, 0, 3 and 2 or the like. The addresses are generated in alternate order as well so that the word can be put into the proper address inside the memory.  With this method, the order to extract and read data always shows the continuation of odd and even numbers in spite of the dimension of the image.

Abstract: PROBLEM TO BE SOLVED: To prevent a gusset part from being expanded or peeled when an article is stored inside by providing a small hole inward of the gusset part of a part where an end seal part of a bottom part and a user seal part of a mouth part are passed, and arranging heat-sealable surfaces opposite to each other through the small hole. SOLUTION: Small holes 22, 23 and small holes 26, 27 are respectively formed at intersection parts of passages of an end seal part 18 and a user seal part 21 with gusset parts B, B'. Taking the small hole 22 as an example, a small hole 22a opposite to a laminate film 12 and a small hole 22b opposite to a laminate film 11 are formed at positions opposite to each other. Thus, when the end seal part 18 and the user seal part 21 are formed, the heat seal is also effected at the small holes 22, 23, 26, 27. Since a heat-seal part is locally constituted inward of the gusset parts B, B', the gusset parts B, B' are not expanded outwardly even when the article is stored.

Abstract: PURPOSE:To obtain a sufficient damping effect with a simple structure by using a damping steel plate as the material of a timing pulley plate for supporting a timing pulley being a vibration-causing source. CONSTITUTION:A dumping steel plate for use on a timing pulley plate 6b has an organic material 15 with a high damping performance interposed between steel plates 13 and 14 and these steel plate are fastened together by this organic material, thus offering a large damping ability. Therefore, the vibration is prevented from transmitting from a timing pulley 5 to a chassis 4 without using rubber bushing. Since the surface of the damping steel plate is not large in friction coefficient, as opposed to the rubber bushing, when the tension of a timing belt 3 is adjusted, the timing pulley plate 6b is easily moved relative to the chassis 4 and, therefore, the tension of the timing belt can be adjusted easily.
