Abstract: PURPOSE:To provide a legless chair for which it is not necessary to move a Japanese foot warmer (kotatsu) or a table when using the kotatsu or the table by vertically driving a receiving stand to place a sitting part of the main body of the legless chair with right and left vertically driving mechanisms and horizontally sliding the receiving stand through a slide driving mechanism. CONSTITUTION:When an operation button is depressed in the state of most elevating a receiving stand 3 by driving moving members 40-43, a driving motor 47 is turned backward, and rotary driving shafts 37 and 38 are rotated. Then, the moving members 41 and 43 screwed to the rotary shafts 37 and 38 are moved backward and on the other hand, the moving members 40 and 42 are moved to the top end of the rotary driving shaft 37, and the bottom of the receiving table 3 is lowered almost on the ground. When the receiving stand 3 is most lowered, at the same time, engage parts 62a and 7b are engaged with each other and then when the operation button is depressed, the driving motor 61 is turned forward. Then, a moving member 62 is gradually moved toward the top end of the rotary driving shaft 38 together with the receiving stand 3.

Title: Throwaway tip
Inventor: YAMADA KENJI
IPC: B23B27/18
Filed: 1994-03-24
Abstract: PURPOSE:To decrease the consumption volume of a superhigh pressure sintered body to reduce the manufacturing cost, and enhance the strength of a compound material or the durability of a tip. CONSTITUTION:In a tip in which the undersurface 5a of a cemented carbide 5 of a compound material 6 obtained by burning a CBN sintered body 4 on the rake face 7 side monolithically with a cemented carbide 5 on the opposite side, is brazed on the bottom face of a recessed part 3 of a tip body 2, the relationship between the lengths L1, L2 of cutting edges K1, K2 starting from a corner C of the CBN sintered body 4 in the directions along two sides H1, H2 of the tip body 2 which put the corned C between them, is determined to be L1> L2 to have a convenient side. Since the cutting edges are arranged, to have a convenient side, a small amount of the CBN sintered body 4 is enough to maintain specified lengths of the cutting edges. Because a brazing filler metal enters between the undersurface 5a of thecemented carbide 5 and the bottom face of the recessed part 3 of the tip body 2, any overhang is not produced on the CBN sintered body 4, and thus the strength of the tip against main component force applied to the tip during the cutting operation is large.

IPC: H01L33/62
Filed: 1987-03-31
Abstract: PURPOSE:To increase a radiant power output by forming a light-emitting diode chip into a mesa shape in a semiconductor device including an outer lead. CONSTITUTION:An LED chip 2 is loaded onto an element base section for a header 3 through a solder layer 4 consisting of silver paste. Since the LED chip 2 takes a mesa shape, the quantity of creeping onto the side face of the LED chip 2 of the solder layer 4 is reduced. An electrode 5 shaped onto the top face of the LED chip 2 and an inner lead 6 are connected by a metallic wire 7. The header 3 connected to an outer lead 9 and the inner lead 6 connected to an outer lead 10 are sealed with a translucent resin body 8, thus shaping an optical semiconductor device. Accordingly, since creeping onto the side face of the LED chip of the solder layer is prevented by forming the LED chip to a mesa shape, the exposed surface area of the LED chip is increased, thus elevating a radiant power output.

Title: Method and apparatus for transporting wafer
Inventor: MACHIDA AKIRA
IPC: B65G54/02
Filed: 1987-03-31
Abstract: PURPOSE:To enable the non-contact carrying of a semiconductor wafer, and to reduce power consumption by applying DC voltage to a plurality of plate electrodes horizontally mounted into a suction substrate while blowing off a gas from a blow-off port for the suction substrate. CONSTITUTION:DC voltage is applied selectively to a plurality of plate electrodes 1-4 set up to a suction substrate 5 by a DC power 8, thus sucking a wafer 6. When a gas is blown off from blow-off ports 7 shaped to the substrate 5 at the same time, the wafer 6 is held at a regular interval from the substrate 5. Force in the horizontal direction is generated by the difference of the opposed areas of the electrodes 1-4 and the wafer 6, and the wafer 6 can be carried in a non-contact manner in the arbitrary direction. Accordingly, the dust-free carrying of the semiconductor wafer is enabled, and only the surface charges of the plate electrodes and the wafer are used as electric energy consumed, thus reducing power consumption.

Abstract: PROBLEM TO BE SOLVED: To enhance a brazing material in bonding strength to a metal fixing member and to improve a gold plating layer in wettability to the brazing material so as to mount the metal fixing member firmly on a base body by brazing, by a method wherein the exposed surface of a glass through which a light transmitting member is fixed inside the metal fixing member is covered with a protective film. SOLUTION: A light transmitting member 9 is fixed inside a metal fixing member 8 through the intermediary of a glass 14 so as to stop up the inside of the metal fixing member 8. Then, the exposure surface of the glass 14 which fixes the light transmitting member 9 to the metal fixing member 8 is coated with a protective film P. A nickel plating layer 12 and a gold plating layer 13 are successively deposited on the surface of the cylindrical metal fixing member 8 so as to surely and firmly fix the cylindrical metal fixing member 8 to a base body 1. The metal fixing member 8 is fixed by brazing to a metal layer previously deposited around a through-hole 1b bored in the metal fixing member 8. By this setup, the nickel plating layer 12 is prevented from being partially diffused into the surface of the gold plating layer 13 and exposed to light for the formation of a nickel oxide layer.

Title: Liquid level detecting device
Inventor: NAGASHIMA HIROSHI
IPC: G01F23/76
Filed: 1983-05-09
Abstract: PURPOSE:To improve vibration resistance, detecting accuracy, life and explosion proof, by the constitution, wherein a float is inclined up and down with the increase and decrease in liquid level, a sealed liquid is moved in the approaching direction or in the separating direction, and a clad stripped part is immersed into the liquid or reversed and exposed out of the liquid. CONSTITUTION:When a liquid level reaches a specified upper limit, a float 1 is inclined upward. A liquid 6 in a liquid chamber 3 flows in the direction to a clad stripped part 4 by the action of gravity. The part 4 is immersed in the liquid. The light from a light emitting element 5a is dispersed from the clad stripped part 4 and is not transmitted to a light receiving element 5b. Based on this state, reaching of the liquid level to the specified upper limit is electrically detected. When the liquid level reaches a specified lower limit, the float 1 is inclined downward, and the liquid 6 flows in the separating direction from the clad stripped part 4. The part 4 is exposed out of the liquid. The light from the light emitting element 5a passes the core of the clad stripped part 4 and is transmitted to the light receiving element 5b. Based on the light received state, reaching of the liquid level to the specified lower limit is electrically detected.
