Title: Method for plating fine pattern
Inventor: MAYUMI YOSHIYUKI
IPC: C25D5/08
Filed: 1984-05-28
Abstract: PURPOSE:To manufacture a printed circuit having a finer pattern by stirring a plating soln. by air blowing and cathode rocking so as to prevent the formation of a circular unplated part and burning. CONSTITUTION:When a fine pattern is formed on a substrate for a precision printed circuit by plating, a plating soln. is stirred by cathode rocking at >=1.0m/ min linear velocity in a direction parallel to an anode and air blowing at >=0.01m<3>/min flow rate per unit area (m<2>) of the bath. Thus, the formation of an unplated part probably due to bubbles or gaseous H2 on a fine circuit pattern in case of only air blowing is prevented, and burining due to reduced limiting current density in case of only cathode rocking is also prevented.

Title: Method for removing low melting metal core
Inventor: KASHIWAZAKI KAZUYOSHI
IPC: B22D29/00
Filed: 1994-05-20
Abstract: PURPOSE:To easily remove a low melting metal core without receiving any restriction in the position and shape of the low melting metal core in a cast product by immersing the cast product contg. the low melting metal core into a salt bath in which nitrates are melted by heating, thereby dissolving away the low melting metal core. CONSTITUTION:The liquid salt bath 3 is prepd. by putting a mixture composed of sodium nitrate and potassium nitrate into a dissolving away vessel B and melting the mixture by heating. The temp. of the salt bath 3 of the nitrates is set higher by plus 50 deg.C than the m.p. of the low melting metal core 1 to be eluted. The cast product A contg. the low melting metal core 1 is directly heated by the salt bath 3 of the nitrates and simultaneously the low melting metal core 1 in the cast product A is heated by coming partly into direct contact with the nitrates 3 when the cast product A is immersed into the nitrates 3. Consequently, the low melting metal core 1 in the cast product A is rapidly dissolved and is eluted from the core taking-out part 2 of the cast product A into the dissolving away vessel B and is thus removed from the cast product A.

Title: Stationary section determining method and segmentation device for voiced sound
Inventor: MOCHIZUKI AKIRA
IPC: G10L25/93
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To determine stationary sections in detail by pitch marks. SOLUTION: A pitch mark is determined as to a voiced sound by discriminating whether or not an inputted voice is voiced or voiceless. Then stationary/ nonstationary determinations are made by pitch mark positions and then a similarity between a pitch waveform cut out of a pitch mark position where a determination is made on the basis of the determination result and pitch waveforms cut out from pitch mark position before and after it is used. When this similarity exceeds a certain reference value, it is judged that the pitch mark position where the determination is made is in a stationary section. Consequently, feature quantities such as a spectrum are found by pitch waveforms, so the feature quantities are not smoothed; and stationary/nonstationary determination is made by the pitch mark positions, so stationary sections can be determined with precision finer than that of a frame analysis.

Title: Water-cooled breaker and removing method for oil-can from flash smelting furnace
Inventor: FUJII OSAMU
IPC: C22B15/00
Filed: 1981-07-09
Abstract: PURPOSE:To easily remove oil-can accumulated on the uptake of an flash smelting furnace for copper while saving man power without requiring skill by using a water-cooled breaker. CONSTITUTION:When heat of hot water gas generated in a flash smelting furnace for copper is recovered with a boiler, oil-cans grown on the uptake of the exhaust port of the furnace by the accumulation of ore dust, and the waste gas permeability is reduced, resulting in a lower rate of operation of the furnace. To remove the oil-cans a water-cooled rod 24 repeatedly hits on the oil-cans 21. By working the 3rd hydraulic cylinder 20 and a pneumatic cylinder 22, the force of an impact hammer is provided to the rod 24. The rod 24 can be brought into contact with the position of the oil-cans 21 on the uptake 2 at a suitable angle by horizontal movement by a hydraulic cylinder 14 on a carriage 8 and rotation by the 2nd hydraulic cylinder 16. Thus, the oil-cans can be easily removed without using fuel such as heavy oil.

IPC: G01F23/30
Filed: 1981-07-11
Abstract: PURPOSE:To indicate that the pressure of an object to be sensed is above the prescribed value by swing a pointer of an oil pressure gauge significatly when the pressure thereof exceeds the value with the resistance value of a sensor for an automobile varying greatly when closing the prescribed value. CONSTITUTION:When the oil pressure is low, a substrate 29 is tilted back to incline movable levers 26 and 27 backward to bring the lever 27 into contact with a terminal 35 of a warning lamp 24, causing the lamp 34 to light. As the pressure rises, an engine oil coming from a pressure introduction path pushes a diaphragm and the substrate 29 is pushed up with a push pin 23 to turn forward while the movable levers 26 and 27 turns forward. Consequently, the movable lever 27 separates from the terminal 35 and contacts a terminal 36. At this point, the other end of the lever 27 is grounded 40 through a case 21 of a sensor (a) and the circuit resistance of an oil pressure gauge 34 drops so sharply to swing the pointer 41 of the gauge 34 significantly.

Abstract: PURPOSE:To miniaturize a lithium tantalate (LiTaO3) signal crystal piezoelectric element by selecting the dimension ratio of the piezoelectric element and that of the piezoelectric element and electrodes within a specific range. CONSTITUTION:Cutout faces of an X plate of LiTaO3 signal crystal LiTaO3 of the piezoelectric element 2 are used as opposed major faces, the lengthwise direction is selected to -50 deg.+ or -2 deg. with respect to the Y axis and electrodes 3, 4 and lead patterns 3a, 4a are formed to each of the opposed major faces. The ratio W/H of the width W and the thickness H of the piezoelectric element is selected as 0.5-1 and the ratio l/H of the opposed length (l) of the electrodes to the thickness H is regulated to 6-8. Then the piezoelectric element is miniaturized more than a conventional LiTaO3 whose W/H is >=1.35 and the equivalent characteristic to that of the conventional piezoelectric element is obtained.

Title: Evaporated fuel processor of lean-burn internal combustion engine
Inventor: HIYOUDO YOSHIHIKO
IPC: F02M25/08
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To increase the purge amount of an evaporated fuel by providing a purge control means for controlling at least a differential pressure changing means according to the burn condition of a lean-burn internal combustion engine to regulate the evaporated fuel amount introduced from a purge passage to an intake passage. SOLUTION: When an ECu 40 purges an evaporated fuel, as the quantity of fresh air flowing into an intake pipe 18 downstream from a throttle valve 21 is decreased, the intake pipe negative pressure is increased so that a pressure difference between the upstream side and the downstream side of a purge passage 49 is increased. Thus, the throttle valve 21 and an actuator 22 realizes a differential pressure changing means. The ECU 40 corrects an opening of the throttle valve 21 according to the burn variation of an internal combustion engine 1. By correcting the opening of the throttle valve 21, the purge amount is roughly controlled, and by correcting an opening of a solenoid valve 39, the purge amount is fine controlled. The ECU 40 thus controls the throttle valve 21 (actuator 22) and the solenoid valve 39 to realize the purge control means.

Abstract: PURPOSE:To allow accurate positioning by providing expandable bags each made of a liquid-nonpermeable film and having an input/output port of a pressure liquid in chambers in a cylinder into which the pressure fluid flows. CONSTITUTION:Expandable bags 12, 13 formed with tube-shaped protruded sections 12, 13a as input/output ports of a pressure fluid is provided in both the right and left chambers A, B partitioned by a piston 2 in a cylinder 1. Thereby, the pressure fluid is poured into the bags 12, 13 to expand them and drive the piston 2, thus the operating fluid is prevented from leaking outside the cylinder 1, and accurate positioning is allowed. In addition, it is unnecessary to strictly control the gap accuracy between an O ring and a sliding opposite member and between the cylinder 1 and the sliding member of the piston 2, thus facilitating the production of an extremely small cylinder or the like.
