Title: Apparatus for generating data relating to speed of rotation of internal-combustion engine
Inventor: IZUMI KOUICHI
IPC: G01P3/489
Filed: 1983-01-19
Abstract: PURPOSE:To achieve stable control, by improving responsiveness by providing a means for producing data representing the pulse generating period of a rotation sensor, an average-speed calculating means and a means for calculating change of speed with time. CONSTITUTION:At a step (a), an average speed M is calculated by doubling the inverse number of the sum of a period Tn indicated by the period data of this time and a period Tn-1 indicaed by the previous period T. Then, at a step (b), the rate of change in the engine speed per unit time, i.e., DELTAN/DELTAT is calculated. Further, at a step (c), a final engine-speed data NDATA is obtained by multiplying the value of DELTAN/DELTAT by a constant K1 and the value Mn of the average speed data. Thus, since pulsating components of the engine speed are removed and a speed of rotation not causing delay to the actual speed of rotation of an engine can be obtained, it is enabled to prevent hunting of the engine and to control the fuel injection rate in a stable and highly accurate manner.

Title: Magnetic head and its production
Inventor: UEHARA TOSHIO
IPC: G11B5/127
Filed: 1992-01-16
Abstract: PURPOSE:To enhance productivity and to necessitate the smaller energy required for production by forming gap spacers by vapor deposition on magnetic gap surfaces subjected to boundary ion cleaning. CONSTITUTION:The magnetic head 24 for audio purposes is constituted by housing a magnetic core 26 having a coil 30 in a shielding case 34 and packing an epoxy resin therein. The spacers 42 consisting of SiO2 are deposited by evaporation on the gap surfaces of the magnetic gap 32. The production of the magnetic head 24 is executed by cutting out 'Permalloy(R) to a prescribed shape and packing half cores as works into a vapor deposition device. O ions are cost toward the works from an ion gun under a reduced pressure, by which the works are subjected to the boundary ion cleaning. The works are thereby subjected to impurity removing and degassing. The adhesive power of the magnetic cores and the gap spacers are increased and the hardness and wear resistance of the spacer are improved.

IPC: H01J9/227
Filed: 1994-01-25
Abstract: PURPOSE:To correct luminous exposure using a correcting lens composed of continuous curved faces by combining a correcting lens with a light quantity filter by which the distribution of the light quantity in a specified area is made lower than that in the area besides the specified area and exposing a layer of a fluorescent plane forming material. CONSTITUTION:A correcting lens 31 is composed of two correcting lens 35a, 35b which correct miss-landing 34 of a curl pattern produced on an object in the fourth quadrant of a fluorescent plane 3 of a color picture tube. The lens 35a and the lens 35b are so composed of curved faces as to converge the landing errors on near the vertical axis Y and near the horizontal axis X, resp., of a panel and as to suppress the rest of the landing errors. The correcting lens 31 is provided with a light quantity correcting filter 38a to be combined with the lens 35a and also provided with a light quantity correcting filter 38b to be combined with the lens 35b. These filters 38a, 38b make the distribution of the light quantity near the axis Y and near the axis X be lower than that in the area beside these areas. Consequently, exposure of the layer 16 of the fluorescent plane composing material becomes insufficient even if the area besides the areas near the axis Y and the axis X is exposed and the exposure can be corrected until the exposure reaches a prescribed level.

Title: Incomplete combustion preventing device
Inventor: KAWAHARA KAZUNARI
IPC: F23N5/10
Filed: 1986-01-16
Abstract: PURPOSE:To improve the precision of the incomplete combustion preventing device by providing an electronic circuit for opening and closing an electromagnetic valve by a difference in electromotive force between a main thermocouple and an reverse bias thermocouple. CONSTITUTION:At the time where the concentration of oxygen is lowered or fins are clogged, electromotive forces generated by a main thermocouple 2 and an reverse bias thermocouple act to reduce the difference between thermoelectromotive forces similarly as the conventional example. When the difference in the electromotive forces becomes smaller than the voltage at both ends of a resistor rx, when the potential on the non-inversion input side becomes lower than that on the inversion input side, the output of an operational amplifier IC becomes low, and no current flows to an electromagnetic valve 7. Thus, the valve 7 is closed and the gas is interrupted and the incomplete combustion is prevented. A factor affecting the operation of the incomplete combustion preventing device mostly consists of the main thermocouple 2 and the reverse bias thermocouple 5 and the precision is improved. Further, the electromagnetic valve 7 carries out an ON-OFF operation and the value of a separated current scarecely affect the operation of the incomplete combustion preventing device.

Abstract: PURPOSE:To improve the operability by providing a means for deciding a character kind of an input character-string, an attribute imparting means for imparting an attribute to the input character-string by this character kind, and a switching means for instructing whether an effect of both the means exists or not. CONSTITUTION:In the case a character code inputted from a character input circuit 1 is a character code input example 5, a character kind deciding circuit 3 decides a fact that 0x31, 0x32, 0x8252 and 0x8253 are numerals, and 0x82a0 and 0x82a2 are 'KANA' (Japanese syllabary) from the character code. An attribute imparting circuit 4 imparts a half size attribute and a full size attribute to the numeral and the 'KANA', respectively from the character kind decided by the character kind deciding circuit 3. In this state, when the half size attribute is shown by one byte code, and the full size attribute is shown by two bytes, the attribute imparting circuit 4 executes a processing for changing 0x8252 and 0x8253 to 0x33 and 0x34, respectively, and can match the attributes of every character kind. In such a way, with respect to a character-string input in which different character kinds are mixed, the operation for imparting the attribute comes to be scarcely executed, and the operability is improved.

The top vapor from the column B is introduced into the heat exchanger C, etc. and condensed therein, to recover  a part of the vapor as a product P and to circulate the remainder to the upper part  of the column B. Since a liquid contg. unrefined SAKE does not flow through the  reboiler R at the bottom of the column B, throubles such as pollution and corrosion  are eliminated.
