Title: Layout pattern verifying device
Inventor: KAMAKURA TOMOKO
IPC: G06F17/50
Filed: 1993-02-03
Abstract: PURPOSE:To constitute the device so that even a beginner can execute a design in which influence of a crosstalk is taken into consideration by color-coding and displaying a layout pattern corresponding to a signal line divided into an AC and a DC by a simulation means. CONSTITUTION:By a simulation means 5, circuit diagram data 1 is read in. Subsequently, based on the read-in circuit diagram data 1, net list data 6 for a simulation is extracted, and based on its net list data 6, a circuit simulation is executed. In this regard, an analytic condition of its simulation executes a time analysis. Next, the quality of its simulation result 7 is decided. Also, the simulation means 5 divides each signal line on a circuit diagram into that which an AC signal passes through and that which a DC signal passes through by using the net list data 6, the simulation result 7, and a coordinate data file of the circuit diagram, and allows them to be subjected to color coding. Thereafter, pattern data 9 subjected to color coding is generated, and displayed on a display 4.

Title: Method of controlling terminal ink-transfer recorder
Inventor: OBARA KAZUKI
IPC: B41J2/325
Filed: 1986-02-24
Abstract: PURPOSE:To separate easily and certainly a recording paper and an ink ribbon, by a method wherein only the recording paper is sent and the ink ribbon is kept not to be sent when a power source is tuned on. CONSTITUTION:When a power source is turned on, a thermal recording head 2 is separated from a platen 1. Then, the plate 1 is reversely rotated and a recording paper 4 is, in the reverse direction to an arrow, sent by a fixed distance. While the recording paper 4 is reversely sent, for instance, a ribbon winding roll 9 is held by the friction force of a clutch plate 13 installed to a clutch gear 14 and the flange 10a attached to the ribbon winding roll 9 and an ink ribbon 7 is not sent. Therefore, the recording paper 4 and the ink ribbon 7 are separated. After the recording paper 4 and the ink ribbon have been separated from each other, the recording paper 4 is sent by the same amount as the reversely sent amount or that more than it. Then, the operation of printing follows. Even though the recording paper is stuck to the ink ribbon, they are easily and certainly separated and the jam of the ink ribbon is prevented. Further, because the ink ribbon is not sent, the wastage of the ink ribbon can be eliminated.

Title: Word processor
Inventor: INOUE TAKATSUNE
IPC: G09G5/24
Filed: 1980-03-24
Abstract: PURPOSE: To facilitate the expansion and contraction of characters by using a recording plate on which characters have been recorded correctly instead of a character generator.  
     CONSTITUTION: A desired character is inputted from keyboard 11. Controller 10 discriminates what the input character is. Since which position on recording plate 2 the discriminated character is recorded at is previously found, controller 10 drives X-Y driver 3 to align this character (l) to the optical axis determined by light source 1 and reader 4. Image F of character (l) is formed on image sensor 5. Formed image F is converted into an electric signal in sensor 5. Pattern generator 6 generates several patterns whose shapes are similar to that of image F. In screen memory 7, the character patterns generated by generator 6 are stored. After the final character is inputted, input character contents are printed by printer 9. To enlarge and display characters, the distance between lens L and sensor 5 is increased and to contract them the distance is shortened.

Abstract: PURPOSE:To enable execution of efficient and highly precise measurement by a simple device by using, as a sensor, stabilized zirconia prepared by dissolving a metal oxide of low valence such as CaO and MgO in zirconia. CONSTITUTION:Porous platinum electrodes 2 are fitted on the opposite sides of stabilized zirconia and a reference gas is made to flow on one side of the stabilized zirconia 1, while a measuring gas is made to flow on the other side thereof.

Abstract: PURPOSE: To find a dicing region from the peculiar point of video signals by leading light from a  light source through optical fiber to illuminate the semiconductor surface and picking up the  irregular reflection optical image on the surface in the position detection direction and the  orthogonal direction.  
     CONSTITUTION: Optical fibers 31a and 31b have the exit of a rectangular section, and condense  the light from light source 11 in 13 to illuminate substrate 1 from the oblique directon in the x.y  direction. The irregular reflection light is condensed through lenses 8 and 35 in a fixed direction  and is focused on one-dimensional pickup element 36. After photoelectric conversion, the position  of chip 2 is calculated in 37 to control the driving of stand 40, thereby positioning. Signals including only vertical position information is obtained by the illumination of optical fiber 31a for rough  detection, and the lowest level indicates pad row intervals in the vertical direction. Optical fiber  31a is switched to optical fiber 31b for accurate detection to obtain the center from signal positions corresponding to cut regions while noticing only bright peaks interposing the rough center  which was detected by rough detection, and the horizontal direction position of the chip is detected. By this method, the thermal influence of the light source is avoided, and separation regions  are found easily, thereby detecting the position.

Title: Weight detector
Inventor: MIHARA MAKOTO
IPC: G01G21/23
Filed: 1987-02-20
Abstract: PURPOSE:To obtain ideal sensitivity characteristics by making the structure of a load transmission member spherical, and making the sensitivity high at the time of large weight which does not require a fine difference in weight and low at the time of a small load. CONSTITUTION:The load transmission member 4 which receives and transmits a load W to the surface of a diaphragm 1 is shaped spherically. Therefore, the contacting area between the diaphragm 1 and member 4 becomes smaller and smaller as the load W becomes smaller and smaller, and the sensitivity to the bending of the diaphragm 1 decreases, so the resolution of measurement at the time of a light load is improved. When the sensitivity increases at the time of a large load, on the other hand, so fine resolution is not required at the time of the large load, so there is no problem and practically ideal sensitivity characteristics are obtained.
