Title: Surface acoustic wave filter
Inventor: NAGATSUKA TSUTOMU
IPC: H03H9/145
Filed: 1993-03-09
Abstract: PURPOSE:To realize a small loss and a large extent of out-band attenuation by constituting a surface acoustic wave filter of an one-post surface acoustic wave resonator and a surface two-ports acoustic wave resonator. CONSTITUTION:A surface acoustic wave resonator 4 to one terminal has such impedance characteristic that the impedance is 0 in the case of a resonance frequency fr and is infinite in the case of an antiresonance frequency fa. Consequently, the electric signal from an input terminal 6 passes an output terminal 7 in the case of the frequency fr but does not pass it at all in the case of the frequency fa to generate an attenuation pole when resonators 4 are connected in series to constitute a circuit to two terminals. Meanwhile, a surface acoustic wave resonator 5 to two terminals generates a spurious wave in a high band-side vicinity fs of the pass band. However, the spurious wave of the resonator 5 is cancelled by the attenuaLion pole of the resonator 4 to increase the extent of out-band attenuation because resonators 4 and 5 are cascade connected and are so constituted that frequencies fa and fs are equal to each other. Further, the pass band of the resonator 5 is equalized to the frequency fr of the resonator 4 to reduce the insertion loss in comparison with multistage connection of resonators 5.

Title: Printing pressure adjusting device for typebar of japanese typewriter
Inventor: KIMURA YUKIYASU
IPC: B41J7/94
Filed: 1979-04-19
Abstract: PURPOSE: To shorten the time required for printing by a method wherein a typebar is started at a high speed initially and braked near a platen when a character of few strokes is printed under the weaker pressure.  
     CONSTITUTION: When a type 4 of relatively few strokes is printed, a knock-up lever 5 knocks up the type 4 from a type case 3, makes a typebar 7 hold it and then solenoids 13 and 19 be electrified, thereby an arm 27 being rotated and a brake arm 25 being positioned for action. Concurrently with this, a rod 18 is lifted and an action arm 15 moves an engaging part 11 upward, thereby the typebar 7 rising near to a platen 2 and touching the project of the front end of the brake arm 25. However, since the rise of a touching plate 21 is held down by a spring 24, the starting speed of the typebar 7 is attenuated. When the character of relatively many strokes is printed, only the solenoid 13 is electrified. Therefore, the brake arm 25 is retained in the waiting position and so the typebar 7 is not braked.

Title: Method for reinforcing grooved slope
Inventor: YAMADA YASUHIRO
IPC: E02D17/20
Filed: 1998-02-14
Abstract: PROBLEM TO BE SOLVED: To economically construct on the surface layer of a slope a structure which does not project to the surface of the ground at all to keep the natural environment and view. SOLUTION: Grooves 1, 1 are drilled in a slope while crossing one another lengthwise and crosswise. A broad tension member 2 woven in the form of a strip and made of a synthetic resin or the like is placed in the groove 1. A permeating hardener 3 is injected toward subsoil to permeate the subsoil. A hardener 4 of high viscosity is injected into the groove 1 to construct a structure 5 where the tension member 2 is integrated with natural ground by the hardeners 3, 4. Therefore, the structure 5 extends lengthwise and crosswise over the natural ground and functions to prevent the collapse of a surface layer, so that even if a part of the natural ground collapses, it is supported by the peripheral structure 5 to prevent collapse. Since no structural parts project onto the surface of the ground, the structure serves to conserve the natural environment and view.

Abstract: PURPOSE:To enable an nitride or oxide film to be selectively removed by anisotropic etching without defects in an underlying gate electrode material or diffusion regions, by growing a polycrystalline silicon film under the silicon nitride film or silicon oxide film. CONSTITUTION:After forming a field oxide film 2 and a gate oxide film on a P-type silicon substrate 1, a gate electrode 3 is provided and phosphorus ions are implanted to form diffusion regions 4. An oxide film 5 is formed to cover the gate electrode 3 and diffusion layer 4. A polycrystalline silicon 6 is deposited by means of the CVD process and a silicon nitride film 7 is further grown thereon. The silicon nitride film 7 is etched by the plasma etching until the underlying polycrystalline silicon 6 is exposed. The polycrystalline silicon 6 is then etched by the plasma etching until the underlying oxide film 5 is exposed. Since the oxide film has a low etching rate, the oxide film and the field oxide film 2 over the diffusion regions 4 are hardly etched. Finally, As ions are implanted to form N<+> type diffusion regions 8.
