Inventor: TAKEUCHI HAJIME
IPC: B05B5/04
Filed: 1987-03-19
Abstract: PURPOSE:To prevent the deformation of a paint guide groove, by forming the leading end part of a spray head, which reaches the cup-shaped inner peripheral surface of an annular flat surface from the inner peripheral edge thereof, from a conical surface expanding toward the outside, and forming a large number of paint guide grooves only to the inner peripheral edge of the conical surface. CONSTITUTION:The outer peripheral edge part 10 of the leading end part 9 of a spray head is made vertical to the rotary axial line of a rotary shaft 1 and formed of an annular flat surface having a width l1 over the entire periphery. The leading end part 9a reaching the cup-shaped inner peripheral surface of the annular flat surface 10 from the inner peripheral edge 11 thereof is formed from a conical surface expanding toward the outside. A large number of paint guide grooves 12 are formed only to the inner peripheral edge part of the conical surface 9a and paint guide surfaces 13 are formed between paint flow-out ends 12b and the annular flat surface 10. By this constitution, each paint guide groove 12 and each paint flow-out end 12b are formed inside the annular flat surface 10. Therefore, even when the spray head 2 is detached, the paint flow-out ends 12b can be inhibited from deformation due to the contact with other object.

Title: Catalyst for removing nitrogen oxide and production thereof
Inventor: YOSHIDA NAOMI
IPC: B01D53/94
Filed: 1995-03-22
Abstract: PURPOSE: To obtain a denitration catalyst thermally stable and enhanced in NOx removing rate by forming a porous carrier wherein a specific amt. of TiO2 particles are present in the gaps of a clay layer by a simple preparing method and supporting a highly active metal component on the surfaces of the pores thereof in a highly dispersed state. CONSTITUTION: TiO2 dispersed in water and a smectite clay mineral having an interlaminar structure are formed into viscous paste in a wt. compounding ratio TiO2 /(TiO2 +clay)×100=50-99.5 wt.%. This paste is kneaded under shearing and subsequently dried and solidified to be washed with water and, thereafter, vanadium is supported to obtain a denitration catalyst. It is important to preliminarily mixing the clay mineral and 50wt.% or more of the TiO2 raw material. By this method, TiO2 particles are mutually separated by a clay layer and the sintering of TiO2 particles can be prevented and, as compared with a conventional intercalation method inserting TiO2 particles in the gaps between clay layers, the almost equal heat resistance of TiO2 particles can be obtained.

Title: Thermal recording body
Inventor: RYU YUKIKO
IPC: B41M5/337
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To enhance the light fastness of a ground part, and also improve the oil resistance and resistance to vinyl chloride of the coloring part and ground part and reduce head scum and sticking by adding at least one kind of 2,6-naphthalenedicarboxylic acid derivative expressed by a specific structural formula. SOLUTION: At least, one kind 2,6-naphthalenedicarboxylic acid derivative shown by formula is contained as a UV absorber. In the formula, R1 and R2 respectively show a hydrogen atom, a 1-10C alkyl group, an aryl group, an aralkyl group, a hydroxyalkyleneoxyalkyl group or an phenyl group. Since the 2,6-naphthalenedicarboxylic acid derivative has a high melting point, sticking or the like due to melting does not occur during recording in a thermal head. Furthermore, since it has a low dissolving property to a solvent, elusion does not occur even if it comes in contact with an oil or a plasticizer, resulting in no impairment of a barrier property of the protecting layer, and thereby an oil resistance or resistance to vinyl chloride of the coloring part and ground part is improved.

Title: Production of water-soluble phenolic resin
IPC: C08G8/00
Filed: 1992-03-18
Abstract: PURPOSE:To obtain the title resin desirable for the production of a mold having high strengths, good workability in kneading and mold formation and excellent disintegrability after pouring a molten metal by limiting the content of at least trinuclear polymeric compounds in a specified range and lowering the content of a mononuclear compound component which does not contribute to the strength of a mold. CONSTITUTION:Phenol is reacted with formaldehyde in a molar ratio of 1:(1.6-3.0) in the presence of a reaction catalyst comprising an alkali metal compound and/or an alkaline earth metal compound. When the content of at least trinuclear polymeric compounds reaches 40-60wt.%, the reaction mixture is neutralized with an organic acid or an inorganic acid, and the neutralized reaction mixture is subjected to treatment (desirably washing with water) to lower the content of a mononuclear compound as a water-soluble component. The obtained resin is mixed with an aqueous solution of an alkali metal compound to adjust the pH of the system to at least 9 and the nonvolatile content to 40-70wt.%. An organic acid ester (e.g. methyl formate or ethyl formate) is used as a curing agent.

Title: Active/reserve switching system
Inventor: SASAKI TAKASHI
IPC: H04B1/74
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To simplify a switching control circuit and to reduce a standby time upto a valid switching starting point exceeding a delay time required for a signal amplifier returning to its active state to be in its normal operation state. SOLUTION: A state change detector 41 issues a switching request using a pulse generated only when a signal amplifier 31 changes its normal operation state to a state other than the normal operation state, while a control circuit 70 does not perform switching from an active to a reserve mode when a request other than this switching request is received. Since the signal amplifier 31 returning to the active state does not erroneously generate the switching request even if the state other than the normal operation state continues within the delay time until the amplifier becomes in the normal operation state, the control circuit 70 causes a switching mask to validate the switching by a reset request.  Thus, it is possible to eliminate a complicated monitoring, the control circuit and the storage area from the control circuit, and a starting time of the switching validation does not have to take into account the delay time until the signal amplifier 31 become in the normal operation state.

Title: Time pulse generating circuit
Inventor: SUDOU TOSHIO
IPC: H03K17/28
Filed: 1979-05-22
Abstract: PURPOSE:To generate stable time pulses by determining intervals of pulse generation at the division ratio of resistances by initializing count pulses by a decoder output when the count value of a counter reachs a certain value. CONSTITUTION:Counter 5 counts up by count pulses as many as N and decoder 6, when the count value of counter 5 reaches N, generates a pulse. Here, the (i) count of counter 5 is determined in a time pulse generation period by count pulses with the 1st time axis supplied to counter 5 and the output of voltage comparing circuit 7. The remaining count N-i of the counter starts at the end of a time pulse by count pulses with the 2nd time axis and when the contents of counter 5 reach  1-N, the count pulses are initialized by a decoder output to determine the intervals  of pulse generation at the division ratio of resistances without reference to the magnitude of an electric power voltage, so that stable time pulses will be generated.

Filed: 1989-03-16
Abstract: PURPOSE:To correct a load cell output automatically by generating weight data based on a counted value corrected by a temperature correcting means. CONSTITUTION:The weight value of a reference weight is measured first under the environment of reference temperature and the environment of different temperature from the reference temperature and counted values outputted from an A/D converter 3 at this time are detected. A keyboard 7 is operated to set the counted value at the time of the reference value in the 1st counted value memory of a ROM 5 and also set the counted value at the time of the different temperature in a 2nd counted value memory. Then coefficient arithmetic processing is performed periodically and a temperature correction coefficient C is calculated from the current temperature under the used environment which is measured by a temperature sensor 10. When the measurement of weight is taken by a load cell 1 in this state, the current actual counted value is temperature-corrected with the coefficient C and weight data is generated based upon the counted value after the temperature variation to display the weight on a display device 8.
