Title: Wafer shipping box
Inventor: HORIOKA YUKICHI
IPC: H01L21/673
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To automatically cancel pressure difference between the inside and the outside of a box, to prevent box deformation caused by the pressure difference and contaminants sticking to the side of case, to make the box advantageous in terms of cost, to recycle the box and to hardly transfer impulse to a wafer as well. SOLUTION: When external atmospheric pressure changes and an inner/outer pressure difference occurs in a sealed wafer shipping box 10, air flows from the side of higher pressure to the side of lower pressure between the inside and outside of this box via a filter 20. Therefore, this pressure difference is automatically canceled. As a result, the damage of a wafer case 11 or silicon wafer W due to box deformation caused by the pressure difference can be prevented. Contaminants are filtered by the filter 20 and will not infiltrate the inside of the box 11. Furthermore, since a structure is simple, these effects can be provided comparatively at low cost.

Title: Working method of metal tube having groove in inside surface
Inventor: TATSUMI ARITAKA
IPC: B21C1/24
Filed: 1979-02-01
Abstract: PURPOSE: To manufacture a heat trensfer tube having in inside surface thereof grooves whose depth varies longitudinally at a constant pitch, by pressing the moving metal tube between a grooving plug and rotating balls arranged in a rotating heat, and by making smooth the outside surface of the tube by means of a finishing die after grooves have been made on the outside and inside surfaces of the tube.  
     CONSTITUTION: When a floating plug 4 is inserted into a metal tube 1, which is driven by pulling, the metal tube is pressed to a rotating balls 15 accomodated in a rotating head 17 with a grooved plug 5, which is at rest, so that the diameter of the tube is decreased and grooves are made in the inside surface. The rotating balls revolve around the outside periphery of the tube while rotating on its own axis and forms concavo-convex grooves on the outside surface of the tube of height depending upon the rotating speed and the moving speed of the rotating head. Smoothing of the concavo-convex groove by means of a finishing die 13 moves the grooves to the inside of the tube and causes the depth of the grooves to vary longitudinally at a constant pitch. Hence a heat transfer tube having large inside surface area is manufactured.

Title: Loop type lan control method
Inventor: ICHIMURA MAMORU
IPC: H04L12/437
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To easily attain the detection of a defective part and the reconstitution and recover of a loop by transferring information through a transmission line between nodes, and using plural loop type transmission lines. SOLUTION: When transmission line failure is generated, loop transmission is not operated between a station 2 and a station 3, and the stations 2 and 3 recognize the abnormality of a transmission line. A master station which recognizes a station capable of transmission operates loop back frame transmission to the lowest downstream station which does not transmit a monitor frame, in this case, an A system transmission line to the station 2 and a B system transmission line to the station 3. A receiving station is switched to connection through an SD-A 64 and a MODEM I/F-B 80 of a communication control LSI-A 50 with a MODEM-B 81 under the control of an SD switching SW-A 91 of an SD switching controlling part 90.  In the same way, an SD-B 84 of a communication control SLI-B 70 is switched to a MODEM-A 61 so that state switching can be generated in the stations 2 and 3 by operating loop-back.

Abstract: PURPOSE:To apply electroplating of high quality in good yields and with high productivity, by using two control circuits for total currents in changing such as changing of passes, sizes, and line speeds, and controlling total currents continuously. CONSTITUTION:The reference current signal of a control circuit 20 for total current is inputted through a timing change-over circuit 10 to current control amplifiers 8-1-8-n of respective passes, by which the currents of plating power sources 4-1-4-n are controlled. Control circuits 20, 30 for total currents operate the reference signals of the total currents to provide prescribed plating thickness and output the reference signal of the electric power 1/n said signal to each pass. When the detecting means for an optimum current range in the circuit 20  emits commands for pass changing, etc. to a timing device 50, the device 50  outputs a tracking start command to a tracking device 40. According to the  command from the device 40, the circuit 10 changes over the device 20 to the  device 30 so as to avoid interruption in the control of the total currents.

Filed: 1992-01-24
Abstract: PURPOSE:To stabilize the ink discharge condition, and form a good recording image by operating the control unit conforming to the correlation between a nozzle diameter which is previously obtained in response to a recording density, and an input energy quantity to a heater. CONSTITUTION:The voltage from a driving power source varies in response to a continuous tone signal to show recording density, the expansion quantity of a piezoelectric element is made to be variable, and the discharge diameter is varied by making the curvature quantity variable. Since the response frequency of the piezoelectric element at this time is very rapid such as several KHz, a high speed printing becomes possible. A circuit which introduces energy to a heater for discharge is constituted of a heater for discharge 5113, control unit 1000, AND gate 1001 for pulse width information signals which are input from the control unit, and printing data signals, and a driver 1002 of the heater for discharge. The control unit 1000 inputs a pulse to the AND gate 1001 at each driving cycle of a recording head, regardless of the printing signals. The control of the input energy quantity is performed by controlling the previously mentioned pulse width.

Abstract: PROBLEM TO BE SOLVED: To prevent re-adhesion of etching material by plasma etching an Ni based thin metal in an atmosphere containing a compound having a carbonyl group or carboxyl group in molecule thereby ensuring the selection ratio with respect to a mask material. SOLUTION: An Ni based thin metal 22 is deposited on the entire surface of a substrate 21 and a resist pattern, serving as an etching mask 23, is formed thereon in desired pattern. The Ni based thin metal 22 is then subjected to dry etching by a plasma etching system in an atmosphere containing a compound having a carbonyl group or a carboxyl group in molecule before being patterned. Finally, the resist pattern is dissolved to be removed thus finishing the etching process. According to the method, a selection ratio can be ensured with respect to a mask material and re-adhesion of etching material can be prevented.

Filed: 1984-01-27
Abstract: PURPOSE:To obtain a sliding contact material for a micromotor having superior wear resistance in high-load and high-speed rotation while reducing the amount of Cu having inferior oxidation resistance by adding specified elements to an Ag- Pd-Cu alloy for a sliding contact. CONSTITUTION:An Ag-Pd-Cu alloy consisting of 10-80% Pd, 5-25% Cu, 1-5% at least one among Zn, In, Sn and Pb, 0-1.0% at least one between Ti and Zr, and the balance Ag is used as a sliding contact material for the high-speed rotation of a micromotor or the like. Cu has inferior oxidation resistance, and when it undergoes sliding wear, Cu oxide particles are formed to increase the contact resistance, so the Cu content can not be increased. In case of a low Cu content, the precipitation hardenability is reduced. Said added elements prevent the reduction and improve the mechanical characteristics and wear resistance.
