Title: Multilayer ceramic board
Inventor: ABE KENICHIRO
IPC: H05K3/46
Filed: 1988-01-28
Abstract: PURPOSE:To prevent an inner layer of a multilayer ceramic board from decreas ing in a conductive property and cracks from occurring by a method wherein two or more conductor layers are structured in such a manner that they are each made to vary in compositional ratio of CuO powder to Cu powder. CONSTITUTION:Conductor paste layers P1-Pn formed between ceramic layers S1-Sn are composed of organic binder B, Cu powder, and CuO powder, where the compositional ratio of CuO powder to Cu powder of the layers P1-Pn are so set that the layers larger than the layer P1 in distance to either side of the board 1b are made to decrease gradually in the above ratio with the distance, that is, the above compositional ratio of the layers are made to decrease gradually advancing in a thickness-wise direction of the board 1b toward the central layer. Moreover, the above ratio of the layers out of the conductor paste layers P1-Pn such as, for instance, a power source layer and the like high in a pattern density is so set as to be lower than that of layers low in a pattern density. Therefore, a conductor resistance is made to decrease, consequently a conductor property is prevented from deteriorating, and as a large amount of gas is prevented from being generated at one time, a conductor property can be improved preventing cracks from occurring in the board 1b.

Title: Typerwriter device
Inventor: YOSHIKAWA JUNICHI
IPC: B41J19/18
Filed: 1987-01-28
Abstract: PURPOSE:To contrive higher accuracy of printing quality, by separating a group of characters which are used more frequently but for which deviations of printing positions are less conspicuous and a group of characters which are used less frequently but for which accuracy of printing positions is necessary from each other, and selectively using driving pulse rates for a carrier motor through discriminating a character mode for each of the groups of characters. CONSTITUTION:Characters (a, b, c...)which are used more frequently but for which a relatively poor accuracy of printing positions is inconspicuous are grouped into a character group 1, while characters (¦, -,...) which are used less frequently but require higher accuracy of printing positions are grouped into a character group 2, and pulse rates for stopping a carrier as shown in Figs. 1 and 2 are respectively named pulse rates 1 and 2, while a pulse rate for minutely moving and then stopping the carrier as shown in Fig. 3 is named pulse rate 3. Upon a key input, printing mode is discriminated, and when the mode is a bold face printing mode, the carrier is driven and stopped at the pulse rate 2 for high positional accuracy, and is minutely moved and stopped at the pulse rate 3, thereby performing printing. When the mode is not the bold face printing mode, printing is conducted by driving and stopping the carrier at the pulse rate 2 for the character group 2, and at the pulse rate 1 for the character group 1.

Title: Information recording medium
Inventor: WATANABE KENJIROU
IPC: G11C17/00
Filed: 1982-02-08
Abstract: PURPOSE:To make recording performance twice with one disk of two-layered structure, by providing the 1st information recording layer which has high reflectivity to light with the 1st wavelength and low transmittivity to light of the 2nd wavelength, and the 2nd information recording layer which is recordable and readable with the light with the 2nd wavelength.

Title: Rotary vane pump
Inventor: FUNADA GAKUO
IPC: F04C18/344
Filed: 1979-02-21
Abstract: PURPOSE: To lighten driving torque and variation of torque by securing a sufficient dimension of the area of flow passage to discharge port and preventing the formation of shutting-in chamber and preventing both the generation of high pressure in compression stroke and the generation of shutting-in pressure.  
     CONSTITUTION: In the outer peripheral surface of a rotor 5, cut parts 9 which extend to the leading edges of their respective slits 6 are formed. The length of each cut part 9 in the direction of revolution callows the area of flow passage in which a vane 7 opposite to a discharge port 2 goes to the discharge port 2 to increase and allows the shutting-in chamber which tends to be formed immediately after the vane 7 passes through the discharge port 2 to communicate to the subsequent intake chamber. The fluid pressure has the highest value when the vane 7 reaches immediately before the discharge port 2, but at this time, the area of the flow passage which leads to the discharge port 2 is increased by the cut part 9 formed on the peripheral surface of the rotor, so the flow passage resistance can be reduced.

Title: Semiconductor device
Inventor: FURUHATA TOMOYUKI
IPC: H01L21/66
Filed: 1988-01-29
Abstract: PURPOSE:To miniaturize and integrate an integrated circuit device by forming grooves by etching on a semiconductor substrate, forming a semiconductor layer on it by vapor phase epitaxy, and forming stepwise differences as a pattern set with scaled coordinate axes corresponding to the grooves on the surface. CONSTITUTION:Grooves 12 are deeply formed by etching on a semiconductor substrate 11. Thus, even if a semiconductor layer 13 is epitaxially grown on the substrate 11, stepwise differences 14 corresponding to the grooves 12 on the layer 13 are not reduced, but a vernier pattern becomes a clear shape. Accordingly, an accurate mask displacement can be read in a later photolithography step, and a sufficient alignment correcting work can be performed. Thus, a superposing margin in a design rule of an integrated circuit device can employ the capacity value of an exposure unit itself, thereby miniaturizing and integrating the device.

Abstract: PURPOSE:To enhance the operation speed of an armature by reducing the loss of the magnetic flux flowing to a gap as low as possible, by parallely arranging the attraction surface of a yoke and that on the side of the armature at the time of the opening return of the armature. CONSTITUTION:The attraction surface 4a of a yoke 4 in an initial position state and the attraction surface 2a of the armature 2 opposed thereto are arranged in parallel.

When the armature 2 further advances in a printing position, the attraction surfaces 4a, 2a do not become parallel to become an opposed state at an angle larger than parallel and the sharpness of the magnetic flux between the attraction surfaces 2a, 4a becomes well as compared with a parallel case and the return operation of the armature 2 by a return spring 8 is smoothly performed and following response at a higher speed becomes possible.

Title: Turn-off thyristor
Inventor: SUEOKA TETSUO
IPC: H01L29/74
Filed: 1979-02-21
Abstract: PURPOSE:To surely turn off a main thyristor in a short time, by making the width of the base of an auxiliary thyristor substantially larger than that of the base of the main thyristor. CONSTITUTION:A main thyristor 1 is composed of four layers P1, N1, P2, N2. An auxiliary thyristor 2 is composed of four layers P1, N1, P2, N3. Althought the layer N3 is produced by diffusion at the same concentration and same time as the layer N2, the diffusion depth of the layer N3 is made by DELTAxj (5-10mu) smaller than that of the layer N2 so that the voltage drop across the auxiliary thyristor 2 is greater by DELTAxj greater than that across the main thyristor 1. As a result, the time of shifting from the auxiliary thyristor 2 to the main thyristor 1 is shortened and the main thyristor is surely turned off in a short time.

Filed: 1992-01-07
Abstract: PURPOSE: To surely detect the off-hook state of a slave telephone by using logic constitution for responding to the output signals of first and second amplifiers and detecting only small input signal change. CONSTITUTION: A detector for an automatic disconnection function uses the first amplifier 30 for detecting, amplifying and inverting large input signal change, a second amplifier 20 for detecting the small input signal change and the logic constitution for responding to the output signals of the first amplifier 30 and the second amplifier 20 and detecting the presence of only the small input signal change. In this case, a diode D2 and a resistor R11 perform a required logic OR function. When voltage change appears at the inverted terminal of the amplifier 20, a capacitor C3 integrates it, and as a result, by the change in a negative direction appearing at a noninverted terminal, the output signals of the amplifier 20 are rapidly changed from a lowest state to a highest state.  The amplifier 20 is sufficiently highly sensitive and generates signals changed in the entire change range even to a small input voltage in a prescribed period.
