Title: Video projector device
Inventor: GYOTEN TAKAAKI
IPC: H04N5/44
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To eliminate image quality degradation by analog signal changeover by selecting and using only one of plural interface circuits by turning the output of only one of the plural interface circuits to a low impedance state. SOLUTION: Input video signals A are converted to digital video signals and clocks matched with specifications inside this video projector device 17 inputted to a format conversion circuit A1. The converted video signals are controlled by control signals from a microcomputer 16, turned to low impedance or high impedance and outputted to an output connector A4 by a buffer circuit A2. In this case, the microcomputer 16 controls the control signals supplied to input connectors 11 and 12 so as to turn the buffer circuit connected to the format conversion circuit for connecting the input video signals to be selected to the low impedance state and the buffer circuit for connecting the input video signals not to be selected to a high impedance state.

Title: Insulated gate field-effect type moisture sensitive element
Inventor: SAKAI TADASHI
IPC: G01N27/12
Filed: 1986-07-17
Abstract: PURPOSE:To stabilize moisture-sensing characteristic of a moisture sensitive element, by a method wherein a silicon oxide is laminated at a part except for a gate electrode area and a hydrophilic organic compound is filled into a recess of the silicon oxide layer for patterning on a gate electrode. CONSTITUTION:A source region 2 and a drain region 3 are formed on an Si substrate 1. An SiO2 layer 4 and an Si3N4 layer 5 are formed thereon. Thereafter, an SiO2 layer 6 for gate patterning is formed entirely on the layers by sputtering and a portion on the area of a gate electrode 7 is etched away from the SiO2 layer. Then, Cr and Au are evaporated to form a gate electrode 7. Moreover, a hydrophilic material is filled into a recess of the SiO2 layer by a spin coating and is hardened by irradiation of light to form a moisture sensitive film 8 and a gate upper electrode 9 is formed thereon. A drain contact hole 10 and a source contact hole 11 are also formed. Thus, the moisture sensitive film 8 is formed in the recess of the SiO2 layer on the gate electrode thereby stabilizing moisture sensing characteristic with improved tightness in a high- humidity atmosphere.

Title: Cleaning method of color changing device
Inventor: NAKASHIMA HISAO
IPC: B05C11/10
Filed: 1979-12-20
Abstract: PURPOSE: To make it possible to clean a paint feed pipe in a short time, to reduce the quantity of used thinner and to improve the productivity of coating operation, by supplying the thinner and air to the paint feed pipe alternately with an electric signal.  
     CONSTITUTION: With an electric signal, valve 2 provided to supply pipe T for feeding thineer L and valve 2 provided to supply pipe R for high-pressure air A are opened and closed alternately each other. Then, thinner L of about 7kg/cm 2  and high-pressure air A of about 7kg/cm 2  are alternately flowed continuously for 0.5 second each to clean feed pipe 1 for 2W3 seconds each, i,g. 4W6 seconds in total. As a result, a plurality of boundary layer parts between thinner L and high-pressure air A have turbulent flows near the internal wall of pipe 1, increasing a shock to the internal wal. Thus, paint sticking to the said internal wall can easily be cleaned and the in-use times of thinner L and high-pressure air A can be reduced by a half- two thirds that of the usual method.

IPC: G01C21/00
Filed: 1994-07-19
Abstract: PURPOSE:To reduce the error detection rate of a demodulated data when the receiving signals of positioning radio wave from GPS satellites have low and high levels. CONSTITUTION:When a receiving/processing section 12 receives a signal of predetermined level or above from a GPS satellite, a navigation message for each GPS is outputted along with a demodulated data, e.g. the time within the GPS satellite. A receiving position is operated from the demodulated data through a satellite position calculating section 13, a receiving position calculating section 14, and a distance/angle of elevation calculating section 15 before being presented at a display section 16. In this regard, a section 17 calculates a receiving signal level corresponding to the field strength at the receiving position based on the distance between the receiving position and the GPS satellite calculated at the section 15. A receiving detection level (threshold value for demodulation) corresponding to a predicted receiving signal level is then set at the receiving/processing section 12 and a corresponding demodulation data is delivered therefrom.

Title: Absorption type air conditioner
Inventor: YOSHIMURA SHIGERU
IPC: F25B15/00
Filed: 1994-07-19
Abstract: PURPOSE:To provide an absorption type air conditioner in which it has a superior raising in starting of cooling operation and an interior region is rapidly cooled when a cooling operation is started. CONSTITUTION:During a cooling operation, an amount of combustion in a gas burner 11 is controlled to show a value of 6000kcal/h f (predetermined heat quantity or less with a cooling control means 88. When a cooling operation is started, in the case that a water temperature detected by a cold or hot water temperature sensor 86 is 15 deg.C or higher, the amount of combustion at the gas burner 11 is controlled to 10000kcal/h (a maximum heat quantity by a rapid cooling means 89. Then, since the absorption liquid in a boiler 14 is rapidly heated, a difference in concentration of the absorption liquid is rapidly increased and the amount of refrigerant is also increased. In addition, a difference of inner pressure is also rapidly increased. As a result, a rapid evaporation of the refrigerant at an evaporator 18 may occur and a temperature of cold or hot water supplied from the evaporator 18 to an indoor heat exchanger 61 is rapidly decreased to make a fast cooling of an interior region.

Title: Heat exchanger
Inventor: GOTO KOICHI
IPC: F24F13/30
Filed: 1993-07-06
Abstract: PURPOSE:To minimize noise due to interference between the rear flow of a heat transfer pipe and a cross flow fan by a method wherein a notch, whose position is different in each plate fin, is provided at the end rim of a plurality of plate fins positioned between a heat transfer pipe near the cross flow fan and the cross flow fan. CONSTITUTION:When a cross flow fan 17 is rotated into an arrow sign direction B, air, sucked into the casing of an indoor unit which receives the cross flow fan 17, flows from left to right and passes through a heat exchanger 15. In this case, a dead water zone or an eddy current, generated in the rear stream of a heat transfer pipe 21c nearest to the cross flow fan 17, moves to the side of a notch 23b since the stream of air is directed to the notch 23b having a small ventilation resistance. In thes case, notches are at different positions, such as the notch 23a of the lower side of a plate fin 19 and a notch 23b at the upper side of the same, whereby dead water zones P, Q, directed to the upper side and the lower side from the heat transfer pipe 21c respectively, are generated. As a result, positions, whereat the flow of the cross flow fan 17 and the dead water zone are interferred, become two places whereby noise can be reduced remarkably.

Title: Method for preventing formation of electrolytic tinning sludge
Inventor: SATO TOSHIO
IPC: C25D3/32
Filed: 1989-06-29
Abstract: PURPOSE:To inhibit the oxidation of stannous ions and to prevent the formation of sludges by adding compounds consisting of phenolsulfonic acid and its derivatives to an acidic halogen electrolytic tinning bath. CONSTITUTION:One or more compounds selected from phenolsulfonic acid and its derivatives are added to an acidic halogen bath containing stannous chloride and halogen salt, and electrolytic tinning is applied to a steel. Although the compounds to be added produce effects even if added by small amounts, it is preferable that they are added by >=0.1g/l from the view point of concentration control. By this method, the oxidation of stannous ions into stannic ions is inhibited and sludges are remarkably reduced. Accordingly, the necessity of the supply of stannous chloride can be obviated. Further, the number of sludge removing operations from a plating tank and a storage tank can be remarkably reduced.

Abstract: PURPOSE:To eliminate a trouble at a bank side by obstracting a shift to a succeeding processing unless a key operation for printing transfer request information is detected after the information is transmitted. CONSTITUTION:When soft facsimile transmission by a transfer requester is completed, the effect that printing is urged is displayed in a display part 11 and the printing key of an operating part 14 is urged to be depressed.
