Title: Contact strucutre with gallium arsenide and its manufacture
Inventor: AARON JIYUDAN FUREISHIYUMAN
IPC: H01L29/45
Filed: 1992-09-08
Abstract: PURPOSE: To obtain a contact structure for gallium arsenide by forming continuous layers of Ni, Au, Ge and Ni on an n-type GaAs substrate and then forming a metal oxide tungsten layer, a fifth layer, and then rapidly thermally annealing the structure. CONSTITUTION: A contact structure for an impurity region 20, which is a doner- doped part of a gallium arsenide substrate 10, is made by depositing five layers on the substrate 10. A first layer is a nickel layer 32, a second a gold layer 34, a third a gallium layer 36, a fourth a nickel layer 38, and a fifth a metal oxide tungsten layer 40. After depositing the five layers separately, the contact structure is thermal-annealed. Thus manufactured contact layer is formed of an intermetallic NiGe compound, including an AuGa compound, coated with a metal oxide tungsten film. Due to this structure, the contact structure can be brought into contact with the n-type GaAs substrate so that the advantage of the n-type GaAs substrate can be made full use of.

Title: Ammonia gas analyzer
Inventor: TANABE AKIRA
IPC: G01N31/10
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide an ammonia gas analyzer by which the concentration of ammonia can be correctly measured, even when the operation and the stop of a boiler is repeated for a comparatively short period. SOLUTION: A control means 6 observes the result of the measurement from a NO analyzer 7b, and judges whether the NO gas concentration is lower than a predetermined limit value or not. When the NO gas concentration is lower than the limit value, the control means 6 stops a pump 5a without switching an electromagnetic valve 3b (operation a), or the control means 6 switches the electromagnetic valve 3b to a by-pass tube 1f side, without stopping the operation of the pump 5a (operation b), and the condition is continued by the time when the NO concentration is over the limit value again.  Thereby, the exhaust gas of thin NO concentration including ammonia can be prevented from passed through a catalyst 1b, even when the boiler is stopped while keeping the operating condition of the ammonia gas analyzer, and the desorption of NO adsorbed to the catalyst 1b and the adsorption of ammonia on a reduction catalyst are prohibited, so that the analyzation of ammonia gas can be correctly performed from the initial time of the restarting of the operation of the boiler or the like.

Title: Manufacture of color filter
Inventor: MIZUTANI YAYOI
IPC: G02B5/22
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To suppress the mixing of pixel materials and the dispersion of pixel density between adjacent picture elements at the time of patterning by jetting picture element material drops from a nozzle at a specified speed. SOLUTION: A piezoelectric element 1 splits continuously jetted ink by vibrating the nozzle 2 and turns it to ink drops (pixel material drops). A charge electrode 3 imparts a prescribed electric charge to the passing ink drop by a pulse voltage applied based on printing information signals. Relating to the ink drops to which the electric charge is imparted in the charge electrode 3, a flying route is deflected corresponding to a charged level by a set of deflection electrodes 4 and they are stuck to the desired position of a transparent substrate 5. The ink drops not stuck to the transparent substrate 5 are recovered into a gutter 6. The speed v (m/second) of the ink drops jetted from the nozzle 2 is defined as 5<v<16 and it is preferable that the mass m (g) of the ink drops is in the range of 5×10<-10> <m<5×10<-8> .

IPC: B41J2/135
Filed: 1990-10-04
Abstract: PURPOSE:To obtain procedures for manufacturing a nozzle plate for ink jet which has excellent nozzle hole diameter accuracy and high print quality by patterning with a photoresist for the formation of a nozzle hole and patterning with a photoresist for the restriction of the diameter of a nozzle hole in the center of a pattern. CONSTITUTION:A photoresist 2 is applied to the surface of a base 1 consisting of a non-metal material. Then after patterning of the photoresist 2 in the form of a nozzle plate, the photoresist 2 is sintered. Next, a photoresist is applied and the photoresist 3 is patterned to the specified nozzle hole diameter in the center of the photoresist 2. After that, electrolytic nickel plating or electroless nickel plating is performed to build a thickness on a plated layer until he tip of the plated film reaches the photoresist 3. Further, the nozzle plate 4 is removed from the base 1 as a mold parting procedure and the obtained nozzle plate for ink jet allows creation of a high-accuracy nozzle hole and discharge of ink droplets of stable particle diameter.

Title: Receiver side terminal equipment
Inventor: SATO FUMIO
IPC: H04M1/00
Filed: 1991-09-19
Abstract: PURPOSE:To easily discriminate the received receiver side terminal equipment by reading and reproducing a voice signal stored in a voice memory with a voice reproduction section so as to send a predetermined call tone. CONSTITUTION:When a call comes to a telephone set and a call signal detection section 2 detects a call tone, the call signal detection section 2 sends the detected call signal to a voice reproduction section 3. Upon the receipt of the call signal, the voice reproduction section 3 reads a voice signal stored in a voice memory 4 and reproduces it and sends it to a speaker 8, from which a sound or voice stored in advance is sounded to inform the arrival of an incoming call. Thus, the incoming call is noticed in a different call tone from each telephone set by reading and notifying a voice signal stored in the voice memory 4 and storing a sound or a voice different every a telephone set into the voice memory 4 as a voice signal. Thus, proper calling is attained by varying the incoming tone optionally.

Abstract: PURPOSE:To form an image extending over many fields by combining and using a light source for oscillating a specific light and a photosensitive zone having sensitivity to its light and a toner, and a toner having an absorbing zone in a visible area. CONSTITUTION:A light source for oscillating a light beam of an infrared area to a visible, infrared or invisible light and a photosensitive zone having sensitivity against the above light and a toner, and a toner having an absorbing zone in a visible area are combined and used.
