IPC: H01L21/338
Filed: 1990-04-13
Abstract: PURPOSE:To enable a submicron size without side etching to be formed by forming a resist pattern for forming a gate on a semiconductor substrate surface and by forming a gate electrode by performing anisotropic etching while light is directed to a substrate surface using a reactive gas. CONSTITUTION:In a method for producing a field-effect transistor, an N<+> type GaAs layer 4 is selectively etched by using Cl2 or CCl2+He gas while emitting a laser beam with a resist 6 as a mask. partial pressure of gas is set to 5Pa. Then, a gate electrode 7 is formed by the lift-off method for eliminating the resist 6 after depositing Ti/Al. This anisotropic etching realizes a fine machining technology which is small in surface damage and improved controllability, thus enabling a high-performance semiconductor device to be produced with improved reproducibility and high yield.

Title: Tuning fork-shape crystal vibrator and its production
Inventor: AOKI KAZUAKI
IPC: H03H3/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To correct the shape of a tuning fork with open legs and to reduce a leakage vibration substantially as the tuning fork with the closed leg shape by executing weighting in the branch part tips of a tuning fork-shape crystal vibration piece which is worked by means of a wire saw so as to permit the bending vibration center of a branch part to be moved to the center axial side of the tuning fork. SOLUTION: Weighting is executed in the tips of the branch parts 2 and 3 of a tuning fork-shape crystal vibrator which is worked by the wire saw and is bending-vibrated on a surface being parallel with the main surface of the tuning fork-shape crystal vibration piece so as to permit the vending vibration center of the branches 2 and 3 to be moved to the center axis side of the tuning fork shape. That is, weights 11 are formed at groove 7 sides from the center line of the branch parts 2 and 3 in the tip parts of the branch parts 2 and 3. The weights 11 are provided at inner sides from the center lind of the branches 2 and 3 so that the vibration center of the branches 2 and 3 is inclined to the inner side of the tuning fork shape and the substantially closed leg-shaped tuning fork is obtained.  When the weights are fitted to the groove 7 side parts of branch side surfaces, an effect is especially large in spite of equality in mass. Thus, a base part distortion quantity is reduced compared with the case of the open leg-shaped tuning fork and also the vertical movement quantity of the base part is reduced.

Further, in a macromolecule outer film 3 with a high mechanical strength, which is coated on the outer surface of the macromolcule inner film 2, a ultraviolet absorbent, light radiation stabilizer and antioxidant, etc. have been dispersed. Therefore, together with the macromolecule inner film 2, the macromolecule outer film 3 shuts out the ultraviolet ray, and the tinting degree for the macromolecule inner film 2 can be lightened. Also, being protected by the macromolecule inner film 2 and macromolecule outer film 3, broken pieces of the glass bottle can be prevented from scattering at the time of breakage.

Title: Method and apparatus for manufacturing powdery formed body
Inventor: SHINOHARA YUKIO
IPC: B22F3/02
Filed: 1982-06-09
Abstract: PURPOSE:To obtain the powdery formed body free from cracks, cut-off, etc., by providing an upper punch having a lower end surface partially insertable along a pressing direction, press-forming powder poured in a die with upper and lower punches, and then smoothly withdrawing the powdery press-formed body from the die and the upper punch. CONSTITUTION:Powder 2 in a die 3 is pressed by the dropping of upper punches and the rising of a lower punch 7. When the pressing power is at the maximum value, the pressure of a coil spring 13 inserted onto an inside upper punch 9 goes under the main pressure of an outside upper punch 8 and the lower punch 7 to bring the upper end surface of the punch 9 into contact with a stopper 11. Consequently, difference in level is formed at the lower end surfaces of the upper punches to reform the pressed powder into a formed body 6 having a projection 14 at is upper part. The withdrawal of said formed body 6 is performed by pushing out the punch 9 downwards with the pressure of the spring 13, since the pressure is reduced by raising the upper punches after the completion of the pressing. At this time, the projection 14 of the formed body 6 is smoothly withdrawn from the cylindrical cavity of the punch 8 without the formation of disorder such as cracks or cut-out in the formed body 6.

IPC: H04L12/56
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To form an extensible electric communication system by enabling each node to transmit/receive variable length packetized information through a network. SOLUTION: Each of exchange nodes 6a to 6h is ring-connected so that the packetized information can be exchanged to/from another node which receives services at an inter node network 12. Thus, a port of an arbitrary node can be connected to the port of an identical node or other arbitrary node by a complete non-intermittent system. Then, every node can be removed from or added to a network 12 without disturbance from another node operation or a network/line interface and an exchange capacity of the node can arbitrarily be selected. Moreover, an electric communication exchange system 2 is controlled by a host 4, and the host 4 and the nodes 6a to 6h perform message exchange by way of a multiple asynchronous communication link 8. This message is used not only for a node configuration but also for the configuration of a direct calling processing function.
