Abstract: PROBLEM TO BE SOLVED: To obtain a pigment composition capable of exhibiting an especially excellent dispersive power, flowability and damping water resisting property in the case of using as a pranographic printing ink by coating a dis-azo pigment with a calcium salt of a rosin and an aluminum salt. SOLUTION: This pigment composition is obtained by coating (A) a dis-azo pigment obtained by coupling (i) a tetrazonium salt consisting mainly of 3,3'- dichlorobenzidine with (ii) a coupling component consisting mainly of acetoacetoxylidide with (B) a calcium salt of a rosin and an aluminum salt. In the component (B), it is preferable to contain 0.1-3mols of calcium and aluminum based on 1mol of rosin, and the ratio of calcium to aluminum is (80:20)-(30:70). Also, the component (B) is preferably 15-40wt.% of the component (A). Thus the composition has an excellent dispersion property and also an effect of reducing a greasing.

Title: Manufacture of cylindrical spring and cylindrical spring produced thereby
Inventor: MOCHIDA HIDEKI
IPC: B21F35/00
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To produce a cylindrical spring, the shapes and sizes of whose outer/ inner diameters, length and end surface are precise by forming a spiral groove to a spring raw material processed cylindrically. SOLUTION: One end surface 1 of a longitudinal direction is processed in a plane shape, after clamping a spring raw material to the chuck of a lathe and processing outer/inner diameters (a), (b) and a length (c) for getting a required size. The spring raw material processed in this cylindrical shape is sent to an axis direction by using a metal saw or an endmill while rotating the cylindrical spring raw material around an axis and a spiral groove 3 matched with the spring dimensions of a desired spring is cut and formed. After forming the spiral groove 3, the other end surface 5 is processed in a plane shape after cutting to a prescribed length (c). Thus, after processing while leaving a clamp margin to the cylindrical spring raw material, it is desirable to cut the clamp margin finally.  The spiral groove 3 can be formed by a discharged processing by a wire electrode or a bar shape electrode and also by the grinding process by a disk shape grinding wheel.

Title: Directivity dynamic microphone unit
Inventor: HOJO MASAYOSHI
IPC: H04R9/08
Filed: 1990-11-01
Abstract: PURPOSE:To make an output frequency characteristic broad while keeping high output sensitivity by forming a small hole linking an outside of a microphone unit housing and an internal air chamber to an acoustic resistance member. CONSTITUTION:A small hole 9a linking an outside of a microphone unit housing and an internal air chamber is formed to an acoustic resistance member 9. A flange 9b is formed to an end face of the small hole 9a toward a direction of a diaphragm inner face air chamber 7 so that a projection length is prolonged more than a diameter of the small hole 9a. Thus, the equivalent mass in the inner air chamber 5 and the diaphragm inner face air chamber 7 is increased by the equivalent mass of the small hole 9a of the acoustic resistance member 9 and the flag 9b of the small hole 9a, the resonance frequency of the diaphragm 1 is decreased to increase the Q (quality factor) at the resonance frequency. Thus, the stiffness of the diaphragm 1 is decreased and the output frequency characteristic is made broad.

Abstract: PROBLEM TO BE SOLVED: To secure the stability during conveying or installing an injection device and a mold clamping device by connecting the rotated motion transmission parts of the devices and each of high power motors corresponding to the rotated motion transmission parts to each other through a rotation transmission mechanism using a rotation transmission belt. SOLUTION: All motors for principal parts to be used in the motor-driven injection molding machine 1 are housed in the internal space S of a machine base 2, together with a servo motor 3 for screw rotation, a servo motor 4 for screw reciprocation and a servo motor 15 for injection device reciprocation. These motors for the principal part and the other motors 3, 4, 15 are arranged in the center, in the right-left direction X, of the machine base 2. The servo motor 4 for screw reciprocation and a servo motor 5 for mold clamping are arranged, with their respective directions reversed to each other, on both end sides, in the forward/backward direction Y, of the machine base 2.  As the servo motor 3 for screw rotation is arranged between the servo motor 4 for screw reciprocation and the servo motor 5 for mold clamping, the center of gravity of the entire molding machine is lowered and the high weight balance is maintained and further the stability of the molding machine during conveying or installing it is ensured.

Abstract: PURPOSE:To perform stable wiring and improve reliability by forming a plurality of electrode leading contact holes putting together the widths thereof into a predetermined length, and constructing a buried electrode by burying those contact holes with an electrode material. CONSTITUTION:In a p type semiconductor substrate 1, a plurality of contact holes 32 are formed through a junction where an n type impurity diffusion layer 2 is formed.

The burying electrode material (W-Si) 5 is buried in the contact holes 32 each having an about 1 aspect ratio substantially in a flat manner. Further, the whole surface is etched and the buried electrode (W.Si) 6 is left behind in the contact holes 32. Additionally, a Ti N film for example is deposited as a barrier metal film 33, on which a wiring material (Al) 34 is deposited for wiring. Hereby, there can be formed wiring with reduced variations and with good reliability.

By this method, the cement molded body which has high strength and is excellent in shock resistance is obtained with good moldability at high efficiency. Such cement molded body is preferably used, e.g., as the floor material of multiple dwelling houses. Furthermore, hazard of carcinogenesis due to waste dust of asbestos is eliminated even in a producing process and even at a time of use because asbestos is not contained.

Filed: 1985-12-27
Abstract: PURPOSE:To make it possible to control fuel feed rate for keeping optimum air-fuel ratio by controlling increments in the fuel feed rate after starting an engine commensurate with the revolutions and load conditions of the engine. CONSTITUTION:A control circuit 28, after discriminating a start based on an energizing signal of a starter motor 50, increases fuel feed rate just after the start commensurate with warm-up conditions detected with a water temperature sensor 42 and decreases as the time elapses.

Title: Tilt controller of car body
Inventor: TSUYUKI YASUO
IPC: B61F5/44
Filed: 1994-12-01
Abstract: PURPOSE: To improve the travel stability of a car body in preventing a cylinder on one side from extending at the same time by opening a bypass circuit via a pilot check valve at the other side by means of high pressure in this main circuit whenever a cylinder on the other is extending. CONSTITUTION: With the body 1 of a train traveling on a curved line, for example, at the time of extending a cylinder 7a on one side, a servo solenoid valve 11a on one side is selected, and operating oil from a pump 10 is fed to the one side cylinder 7a via a main circuit 12a. Then a cylinder 7b on the other is contracted by another servo solenoid valve 11b, keeping another main circuit 12b in low pressure. Therefore a pilot check valve 15a on one side is kept closed intact as its pilot pressure is not raised, so the one side cylinder 7a extends, tilting the car body 1. At this time, a pilot check valve 15b on the other is opened by dint of high pressure in the one side main circuit 12a, through which the operating oil is set free to a tank 10 from a bypass circuit 14b.

Title: Device for extracting voice pitch
Inventor: TAKAKUWA AKIO
IPC: G10L25/90
Filed: 1993-11-30
Abstract: PURPOSE:To extract a voice pitch with a less calculation amount and with less errors. CONSTITUTION:A remaining signal is inputted from an input layer 10 as the learning data, and a value of a pitch obtained by a usual method is made the teacher data, and the learning is performed by a back propagation learning method naturally used in a neural network so that only an output of a neuron of an output layer 30 equivalent to the value of the pitch becomes '1'. Thus, when an optimum waveform (voice) is inputted, in the output layer 30, the connections among respective neurons are formed so that '1' is given in the output of the neuron equivalent to the value of the pitch. Thus, the pitch is obtained only by simple sum of products operation of a multilayer type neural network 50, and the value of the pitch is calculated by a lower calculation amount.
