Title: Surface acoustic wave element
Inventor: HIRAMATSU YASUJI
IPC: H03H9/25
Filed: 1994-12-02
Abstract: PURPOSE: To improve the mass-productivity by laminating a piezoelectric film onto a polycrystal aluminum nitride substrate whose porous rate is within a specific range so as to increase a propagation speed of a surface acoustic wave. CONSTITUTION: A piezoelectric thin film made of a zinc oxide or the like is formed on an aluminum nitride with an excellent surface acoustic wave propagation speed, an interdigital electrode is formed on a piezoelectric thin film or a boundary face between the aluminum nitride and the piezoelectric thin film and a surface acoustic wave is stimulated with the piezoelectric effect of the thin film by applying a high frequency voltage to the electrode and then propagated. When porous is in existence on the way of propagation, the propagated surface acoustic wave receives scattering, the propagation loss is increased and the efficiency of the element is decreased. Thus, an aluminum nitride sintered body whose porosity is 0.2% or below made by the hot press method is used for the substrate and a piezoelectric thin film made of zinc oxide or the like is laminated on the substrate.  Thus, the element almost having no pore with a very small propagation loss and excellent practical use is realized.

Abstract: PURPOSE:To facilitate the design of the beam shape for correction of etching by a method wherein an anisotropic etching operation is conducted after high concentration impurities have been protrudingly diffused on the corner parts or mask-surface direction of a polygon on the top of a mesa, or after a protective work has been conducted using an etching-resisting material. CONSTITUTION:An oxide film is formed on an Si substrate. The oxide film, on the corner of the mask pattern 2, which becomes an Si mesa region, is etched off. Boron is diffused using the above-mentioned oxide film as a mask, and a high concentration impurity region 1 is obtained. Then, the oxide film is etched, a mesa-shaped oxide film is left, and a substrate mask pattern 2 is obtained. This pattern is anisotropically etched and a desired mesa shape is obtained. As high concentration boron is diffused on the top point of the mesa, the corner of mesa is not etched, and the prescribed mesa area can be secured.

Title: Control method of air conditioner
Inventor: FUJISHIRO MOTOYOSHI
IPC: F24F11/02
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a control method of an air conditioner that can prevent a refrigerant from stagnating and reduce wasted power consumption during standby time. SOLUTION: Case temperature Tcmp of a compressor 1a and an outside temperature Tout are detected, and when the outside temperature and the case temperature of the compressor 1a reach a predetermined temperature Ts or lower, preheating of the compressor 1a is started, and when difference between the case temperature of the compressor 1a and the outside temperature become a predetermined value or higher, the preheating of the compressor 1a is stopped. Therefore, even if the outside temperature is low, the preheating is interrupted when stagnation of a refrigerant is dissolved and thus energy is saved. Because preheating of the compressor 1a is also started when the case temperature of the compressor 1a becomes lower than the outside temperature, even if the outside temperature abruptly rises after the outside temperature has decreased to a vicinity of a preheating start temperature for a long time so that the compressor gets cooled, stagnation of the refrigerant is correctly detected and the preheating is started.

Abstract: PURPOSE:To detect a falling off of paper leaf prior to strip-wrapping motion and prevent a strip-wrapping with a quantity other than a designated quantity, by arranging a carrier detecting device which detects that the carrier has moved from the accumulation unit to the half-wrapping unit, and a paper leaf detecting device which detects a paper leaf has fallen from the carrier. CONSTITUTION:Bank notes (P) with a prescribed quantity, which are accumulated on a tray 37, are handed over to a carrier 60 by descending the tray 37 to the lowest position. Next, the carrier 60 starts moving toward a strip- wrapping unit 4; at the same time, a carrier detecting device 70 detects that the carrier 60 has moved. After the carrier 60 has started moving, if a part of bank note (P') has fallen from the carrier 60 on the way to the strip-wrapping unit 4, the fall is detected by either one of paper leaf detecting devices 72, 73, 74. When the fall of a bank note (P') has been detected, a signal to stop the bundling motion at the strip-wrapping unit 4 is sent out.

Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To set parameters for detecting the moment of time requiring replacement of a part easily and to mount a part efficiently based on the set value. SOLUTION: At the time of executing an operation mode where production is conducted using parts on a predetermined priority table the production is sustained by automatically arranging the priority table at a waiting position and arranging a preliminary table at a mounting position upon running out of part, production time per board is measured at step #2 under a state where the part has not run out and only the priority table is used and under a state where the part has run out and both the priority table and the preliminary table are used. At step #6, the difference (or the ratio) of production times calculated under the state where the part has run out and under the state where the part has not run out is calculated and compared with a preset upper limit. Run out of part is alarmed at step #7 when the calculated value exceeds the upper limit.

Title: Between-vehicle distance detecting alarm device
Inventor: NAKAMURA KUNIO
IPC: B60R21/00
Filed: 1990-11-30
Abstract: PURPOSE:To normallize the alarm generation timing by calculating the safe between-vehicle distance, in consideration of the preceding vehicle speed, besides the own vehicle speed. CONSTITUTION:The distance D between an own vehicle 12 and a preceding vehicle 22 is obtained by a laser rader unit 1. The own vehicle speed Vf is detected by a car speed sensor. The speed Va of the preceding vehicle 22 is obtained through the calculation from the variation of the between-vehicle distance D per fine time. The brake distance L1 of the preceding vehicle 22 is obtained by L1=Va<2>/2alpha2 from the preceding vehicle speed Va and the deceleration speed alpha2. The idle traveling distance L2 of the own vehicle 12 is obtained by L2=(Td+Tx)Vf from the own vehicle speed Vf, idle traveling time Td, and the judgement time Tx. The brake distance L3 of the own vehicle 12 is obtained by L3=Vf<2>/2alpha1 from the own vehicle speed Vf and the deceleration speed alpha1. Accordingly, the condition of alarm generation is based on the time when the sum of the preceding vehicle brake distance L1 and the between-vehicle distance D becomes smaller than the sum of the own vehicle brake distance L3 and the own vehicle idle traveling distance L2.

Title: Manufacture of semiconductor device
Inventor: URABE KOJI
IPC: H01L21/285
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To reduce film stress, by forming a titanium nitride film on a semiconductor substrate using chemical vapor deposition method for silicon ion implantation. SOLUTION: After an element isolation oxide film 2 is formed on a silicon substrate 1, impurity is introduced to form a diffusion layer 3. Then an insulating film 4 is deposited and a connection hole 5 is opened. Then, by chemical vapor deposition method, a titanium film 6 and a titanium silicide film 7 are deposited on the insulating film 4 and the diffusion layer 3, respectively. Nitriding process is performed with the titanium film 6 to form a titanium nitride film 8. Using the chemical vapor deposition method, a titanium nitride film 9 of a specified thickness is formed on the titanium nitride film 8. A silicon ion 10 is implanted into the titanium nitride film 9 under a specified condition.  This process increases film density, while tensile stress decreases to about 0.5 Gpa, so WF6 corrosion and distortion of a silicon substrate in W-CVD in post-process due to crack and peeling-off of a film are suppressed, resulting in a stable contact electrode where joint leak is hard to occur.
