Title: Metal etching method
Inventor: SUGIMURA HIROSHI
IPC: C23F1/08
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To speed up the jetting velocity of an etching soln., to suppress the appearance of a side-etching phenomenon and to realize the uniformization of etching by mixing a soln. for etching a metallic surface and a gas such as air or the like to generate micro-droplets and jetting this onto a metallic material. SOLUTION: An etching soln. 3 and a gas 4 such as air or the like are introduced into a two-fluid jet nozzle 2 through separate pathes, and the micro- droplets 5 of the etching soln. mixed in the nozzle and accelerated are jetted onto a metallic material 1 from the tip of the nozzle. In the case where the velocity of the droplets lies in the range of 20 to 350 m/sec by the initial velocity directly after the jetting, the distribution of the grain size is controlled to about 2 to 20 μm, and the soln. temp. is 18 to 35 deg.C, the rupture and peeling of a resist are not recognized, and the improvement of the etching rate, the reduction in the unevenness of etching and the reduction of a side-etching phenomenon are recognized.  These effects are made remarkable in accordance with the increase of the jetting velocity and the soln. temp., and, in the condition in which the droplets 5 whose jetting velocity exceeds the sound velocity, particularly, the etching rate increases.

Title: Rotary joint device
Inventor: HASHIMOTO SHIGEHIKO
IPC: B23Q11/10
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent a fluid from trickling along a rotary shaft to splash electri cal parts. SOLUTION: A rotating side joint 24 is fitted to the upper end part of a rotary shaft 4. When a coolant is filled in a fixed side joint 26, the fixed side joint 26 descends and comes in contact with the rotating side joint 24, and the coolant is filled into the rotary shaft 4 from the fixed side joint 26 through the rotating side joint 24. In the case of this constitution, when there is no pressure of the coolant, the fixed side joint 26 ascends so as to be spaced from the rotating side joint 24, and the coolant leaks from a clearance between both joints and flows in a direction of going away from the rotary shaft 4 along an inclined part 24c of the rotating side joint 24. The coolant is therefore prevented from trickling along the outer peripheral surface of the rotary shaft 4 to splash an encoder 6.

IPC: G03F1/00
Filed: 1985-09-30
Abstract: PURPOSE:To contrive the improvement in a cleaning effect by arranging and adjusting members of a cleaning device properly by using a test piece which is formed by laminating a pressure-sensitive paper on a photomask and a semiconductor substrate and further covering them with a water-impermeable coat and testing it prior to an operation.

Title: Annealing apparatus for optical recording medium and manufacture of optical recording medium
Inventor: KISHI FUMIAKI
IPC: B29C71/02
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To uniformly heat a plurality of substrates and exert a required effect to every substrate when the substrates are annealed simultaneously, by arranging thermostatic plates at both sides of optical recording medium substrates in an annealing apparatus. SOLUTION: When a conveyor 6 moves round, a substrate 8 suspended by a disk hanger 7 is transferred in a substrate transfer path 3 and heated to a predetermined temperature in a furnace 1. Thereafter, the substrate 8 is sent out of the furnace 1 and cooled. Thermostatic plates 2 are arranged in the furnace 1 in a transfer direction of the substrate at both sides of the path 3 to be parallel to both faces of the suspended substrate 8. Therefore, each substrate 8 is uniformly heated from both faces, and a residual internal stress of each substrate 8 during annealing is uniformly eliminated. Since the substrate 8 is heated by the heat of air and radiation heat transmitted from the thermostatic plates 2, the substrate can be heated to a required annealing temperature quickly and an annealing time is shortened, with an annealing effect improved.  Moreover, the path 3 is secured because of the installation of the thermostatic plates 2, making it possible to anneal many substrates 8 simultaneously.

Title: Multilayer interconnection substrate
Inventor: IWATA YASUTOSHI
IPC: H01L23/12
Filed: 1986-09-11
Abstract: PURPOSE:To obtain a highly reliable multilayer interconnection substrate capable of releasing gas in its insulating layers and free from the breakdown of signal layers which affects the semiconductor device functions by utilizing a specially designed meshed metal layer. CONSTITUTION:A metal layer 3 and a signal layer 4 as a ground layer or a power source layer are laminated on an insulating substrate 1 through an insulating layer 2 by a thin film growing technology in a multilayer interconnection substrate. The metal layer is formed in a mesh state so that the void ratio of the layer is 5-80%. Hole parts 3a are provided in the metal layer 3, and the mesh state is obtained. When the insulating layer 2 is heat-treated, and hardened, gas is released through the hole parts 3a in the metal layer 3 even if the gas is yielded in the insulating layer 2. Thus a gas well is not formed beneath the metal layer 3 and an upheaved part is not yielded on the insulating layer 2 at all. The breakdown of the signal layer 4 caused by the stress of the upheaved part is not yielded at all.

Abstract: PURPOSE:To make it possible to execute inspection quickly, and accurately for a long time and to make the cost of the device low. CONSTITUTION:An input signal inversion circuit 2 makes a contact signal from a switch 1 binarized and outputs a contact ON-OFF signal 3. A latch circuit 4 measures time from a reference time to a first rise of the signal 3 and stores it as data D1.

After the last rise of the signal 3 is inputted to the latch circuit 5, a control circuit 6 takes out the data D1 and D2 from the latch circuits 4 and 5, computes a difference between them to determine a chattering time and makes a display unit 7 display it as the result of measurement of the chattering time. Besides, it compares a reference threshold value from a reference threshold value generator 8 with the result of measurement, determines thereby the chattering time as normal or abnormal and makes the display unit 7 display the result of determination.
