Patent JP-H03249349-A (JP)
Title: Fuel supply controller
Inventor: ISHIDA KATSUMI
IPC: F02D45/00
Filed: 1990-02-28
Abstract: PURPOSE:To perform a proper fuel injection early enough at time of sudden engine acceleration by operating a fuel increment portion on the basis of a value made up of dividing a variation of engine operating state parameters by a timer counted value at time of acceleration driving state detection. CONSTITUTION:The absolute value of a difference between an engine operating state parameter value being detected by a state parameter detecting means B1 and a reference value of the state parameter at time just before varied from steady driving to an unsteady driving state, being stored in a memory means B2 is stored in a memory means B3 as a variation of state parameters. When this variation becomes more than the judged value, an engine acceleration driving state is detected by a detecting means B4, and at time of this detection, a fuel increment portion is operated by an operational means B6 on the basis of the value made up of dividing the state parameter variation by a timer-count value by a timer means B5, thereby performing drive and control over a fuel supply means. Thus, even at time of sudden acceleration of the engine, a proper fuel injection conformed to an accelerating degree can be done early enough.

Title: Austenite steel with high strength at high temperature
Inventor: SAWARAKI YOSHIATSU
IPC: C22C38/00
Filed: 1981-03-31
Abstract: PURPOSE: To obtain a heat resistant steel superior to 18-8 stainless steel in both corrosion resistance and strength at high temp. by increasing the amount of Cr, using N for maintaining austenite phase, combinedly adding Al and Mg, and further adding Mo or W.  
     CONSTITUTION: This steel consists of 0.01W0.20% C, ≤3% Si, ≤10% Mn, 20W 35% Cr, 10W45% Ni, 0.04W0.25% N, 0.01W0.5% Al, 0.001W0.05% Mg, 0.5W3.0% Mo and/or 0.5W6.0% W satisfying Mo+1/2W=0.5W3.0, and the balance Fe with inevitable impurities. Both Mo and W increase the strength at high temp. by solubilizing and strengthening, yet less than the lower limits of Mo and W do not produce the effects. They precipitate finely intermetallic compounds such as Fe 2 Mo and Fe 2 W and contribute largely toward enhancing the strength at high temp., yet excess Mo and W deteriorate the workability. Accordingly, the upper limits of Mo and W and the total amount of them in case of combined addition are restricted.

Title: Semiconductor static memory
Inventor: MITANI HITOSHI
IPC: G11C11/41
Filed: 1990-03-02
Abstract: PURPOSE:To eliminate a need of internal timing adjustment and to increase the speed by providing a port selector which alternately switches word line selecting circuits to be activated and a data output buffer which selectively outputs one of data of first and second sets of digit lines. CONSTITUTION:Timing adjustment is not executed for word line selection, and the timing delay is determined by only the operation delay of an address change detecting circuit 2, a port selector 6, and ports. The selected port sets word lines of a memory cell 1 by a word line select signal omegaA (or omegaB) to the high level. Read memory cell data deltaA (or deltaB) is amplified by a sense amplifier of each port and is transmitted as data deltaAo (or deltaBo) to a data output buffer 3. The data output buffer 3 is so controlled that only the output from the port selected by a port select signal lambda is outputted. Thus, timing adjustment is unnecessary to obtain a semiconductor static memory capable of high-speed operation.

Filed: 1988-03-04
Abstract: PURPOSE:To increase the speed of marking work by reducing the moving number of times of a mirror apparatus, by making the dimension of the second mirror in the longitudinal direction thereof longer than that of the first mirror corresponding thereto. CONSTITUTION:A mirror apparatus 17 has function for focusing laser beam 15 and is constituted of the first mirror 26X and the second mirror 26Y. The first mirror 26X is inclined so that the laser beam 15 is emitted in the direction of the second mirror 26Y and the second mirror 26Y is inclined so that the emitted beam goes toward a liquid display device. The dimension l2 of the second mirror 26Y in the longitudinal direction thereof is made longer by about two times than the dimension l1 of the first mirror 26X in the moving direction thereof. Since the first mirror 26X may be moved twice in the x-axis direction within the second mirror and the second mirror 26Y may be moved once in a y-axis direction, the moving number of times may be reduced by one as compared with the conventional moving number of times (4 times) and the speed of marking work can be increased.

Title: Method and apparatus for making expanded plastics container
Inventor: ARAN KEI KURESU
IPC: B29C57/12
Filed: 1979-04-20
Abstract: The present invention is directed to an apparatus and method wherein preprinted rectangular blanks (10A) of longitudinally stretch-oriented foam sheet material are continuously formed into cylinders by a tubular forming mandrel(M) on which the blanks are folded, seamed and thereafter transferred onto final forming mandrels (FM). Subsequently, the blanks and the final mandrels are heated to shrink the blanks so that they assume the shape of the final forming mandrels. In forming containers, means are provided to place bottom blanks on the product mandrels prior to the loading of the cylinders thereon so as to shrink the cylinders to sidewall shapes overlying the bottom blanks. The top curl on containers such as drinking cups and food tubs is formed after shrink forming. Further, the bottom seam of the container may be reinforced by ironing after shrink forming. The bottom blanks are synchronously-fed to the product mandrels at a compatible spacing and velocity after being initially blanked from a web at a different spacing and velocity achieving a minimum amount of scrap in the web.

Abstract: PURPOSE:To accurately and surely attain the program searching of a tape end music by making effective a detecting signal output with music searching by means of a first detecting means only near the numeric value of a counter stored into a second detecting means. CONSTITUTION:When the program of the end music is searched at the time of syncro-copying, and the tape arrives at the end, music searching is executed by a rewinding action in a music searching circuit 1, the interval of the music is detected based on the level of regenerative signals supplied from a head during the searching, and the detecting signal output is generated in the music top part of the tape end music. When the tape is rewound until a stored counter value, the detecting signal output is generated from a memory counter circuit 2. Further, an AND is obtained by a gate circuit 3, the output from the music searching circuit 1 becomes effective only in the range of the numeric value at which a counter is stored, and it is outputted as the music interval detecting signal. Thus, the program searching of the end music is accurately and surely attained.

Abstract: PURPOSE:To control the focus offset with high accuracy by holding the gain of an amplifier means and at the same time applying the offset to a focus servo loop in the gain holding state to fetch the output of a converter means. CONSTITUTION:The output level of a full-wave rectifier 4 is fetched into a microcomputer 8 by an A/D converter 7, and the change of amplitude level of a reproduced RF signal is detected. Thus the microcomputer 8 successively changes the offset value and detects the offset value with which the amplitude level of the reproduced RF signal is maximized. This acquired offset value is finally set at a D/A converter 9 and then applied to a focus servo loop. Thus the best focus servo state is held through the offset control of the focus servo loop.
