Title: Computing circuit
Inventor: KOYA HIROSHI
IPC: G06F7/00
Filed: 1988-12-15
Abstract: PURPOSE:To shorten the computing time by masking the n-bit data which is computable with a half clock with use of the latter half clock of the data strobe to be computed and the masking the precharge following right after the data strobe to be computed for the m-bit data having the maximum computable bit width. CONSTITUTION:The m-bit data to be computed and received via the data transfer buses 1 and 2 are temporarily latched by the input registers 4 and 3 with the strobe signals 7 and 8 respectively. A mask control circuit 5 masks the precharge signals by an amount equal to one piece of the 1st clock at input of this strobe signal showing that the data to be computed is longer than the prescribed value. In this case, the precharge following the stroble of the data to be computed is masked to secure the computing time equivalent to 1.5 clocks with the large number of bits of the computing data. While the precharge is not masked and a computing action is carried out with a half clock after the strobe of the data to be computed in the case the computing data has the small number of bits. Thus the computing action is carried out at a high speed with a data processing job having the small number of bits.

Abstract: PURPOSE:To relieve a semiconductor pellet of a non-defective product and to improve yield of a semiconductor device in an assembling process by recognizing, deciding a lead frame having a defect in its shape before the pellet is placed, and eliminating placing of the pellet of the non-defective product in the lead frame having the defect in its shape. CONSTITUTION:A lead frame 2 supplied from a frame supply unit 10 to a conveying route 11 is recognized in its shape by a picture recognition camera 12 at a front stage to be conveyed to a pellet bonding unit 17, and propriety of its shape is decided by a frame propriety deciding circuit 13. If the shape of the frame 2 is decided to be a non-defective product, a semiconductor pellet 4 is placed on a surface of a tab 2A of the frame 2. On the contrary, if it is decided to be defective, a signal for stopping the unit 17 is output to an arm drive controller 14, and the pellet 4 is not placed on the surface of the tab 2A of the frame 2. Thus, the pellet 4 of the non-defective product can be relieved.

Title: Production of zirconia sol
Inventor: TANAKA KIYOTAKA
IPC: C01G25/02
Filed: 1992-11-27
Abstract: PURPOSE:To remarkably shorten the number of production steps and production time in producing a zirconia sol from an aqueous solution containing a water-soluble zirconium salt. CONSTITUTION:An aqueous solution containing a water-soluble zirconium salt is brought into contact with an anion exchange resin to carry out the ion exchange of anions of the zirconium salt with hydroxyl group ions. Thereby, a viscous gelatinous substance is obtained and then dispersed in water. An organic acid is simultaneously added to the obtained dispersion. Anions of the water-soluble zirconium salt such as zirconium oxychloride, i.e., chloride ions, etc., are removed by the ion exchange with the anion exchange resin without hydrolyzing the anions according to this method and the resultant gelatinous substance can be dispersed in water to readily produce the objective zirconia sol. As a result, the zirconia sol can easily be produced in a short time without passing through both a hydrolytic step for a long period which is a disadvantage of a conventional method and extremely low pH conditions causing problems such as the corrosion of an apparatus.

Abstract: PROBLEM TO BE SOLVED: To reduce the size and weight of speech function equipment by registering the voice print of a speaker in advance prior to a speech, then, comparing it with the voice print of the speaker registered from a signal sound- collected from a transmitter at the time of speaking to extract and send the voice of the speaker and to unnecessitate a microphone for collecting an ambient noise and its circuit. SOLUTION: At the time of registering a voice print of a speaker, a switch 22 is thrown down to the side of a voice print analytic circuit 24 and a microphone collects the voice of the speaker to input the signal to the circuit 24 which analyzes the voice print of the speaker to store it in a voice print memory 26. Then, at the time of transmitting, the microphone collects the voice of the speaker and ambient noise to input the signal to a comparing filter 23. The comparing filter 23 inputs the voice print information of the speaker from the memory 26 at any time and extracts only the voice of the speaker from the signal inputted from the microphone from this information. The extracted voice signal is modulated by a transmission circuit and sent to a base station through an antenna.

Title: Path control system
Inventor: IKEDA YUTAKA
IPC: H04L69/40
Filed: 1988-12-16
Abstract: PURPOSE:To reduce an artificial error without setting a signal attribute of an asynchronous data in an individual management device by outputting logic 1 in the 1st bit of a data part in succession to an ST bit on an asynchronizing signal as a control path from a centralized management device. CONSTITUTION:Only rules are decided that a signal of a control path 107 is formed as an asynchronous (ST-SP) signal 111 and a signal is formed asynchronously between a centralized management device 101 and an individual management device 102. The 1st bit 113 of the data part next to the ST 112 is formed to be logic 1 without fail via a 1-bit transmission/detection means 1021 by an instruction from the centralized management device 101. Thus, since logic 1 appears without fail after the ST 112, the individual management device 102 at a receiver side finds out one bit length when the reception signal is sampled. After the ST bit is confirmed, the next St bit is found out.

Title: Focal point detector
Inventor: KUWATA TOMOYUKI
IPC: G02B7/02
Filed: 1990-11-22
Abstract: PURPOSE:To miniaturize the optical member without impairing the operating efficiency in mounting/adjusting, by fixing an integral optical member, having a plurality of projections in a direction substantially perpendicular to an optical axis, and a retainer member, having grooved portions into which the projections are fitted, by filling an adhesive agent between the projections and the grooved portions. CONSTITUTION:A housing 5 is retained in a posture in which the surface of a lens 4 seen in the view is directed right upwards in a state wherein a re-imaging lens 4 is sufficiently forced into the housing 5 so as to cause the tip ends of columnar projections 43 to 46 of the re-imaging lens to contact with an abutment surface of the housing 5. Then, from the positions indicated by arrow marks D1, D2, D3 and D4, an adhesive agent is caused to drop into grooved portions 56 to 59 corresponding to arm-like projections 47 to 50 by using a commercially available liquid dispenser. The adhesive agent is pooled in a clearance between the surrounding surface of each arm-like projection and the inner wall surface of the corresponding grooved portion facing this surrounding surface in such a manner as to bridge the two opposing surfaces and then is cured. Since the amount of the adhesive agent capable of being pooled in each clearance is set to be large, the agent can be prevented from being carried into the housing 5 from the clearance to contaminate a lens portion 40 and light transmission portions of a stop mask 6.
