Title: Origin detecting device
Inventor: YAJIMA SATOSHI
IPC: B25J19/02
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To detect the mechanism origin of a pan tilt mechanism accurately. SOLUTION: Projection light 4 is radiated from a parallel direction to a shaft which is orthogonal to a pan shaft 6 of a pan tilt mechanism 2 by a projector 3. The projection light 4 is interrupted by the pan tilt mechanism 2, and an interruption detector 8 transmits interruption trigger by an output signal from a light receiving element 5 at that time. When the light is transmitted again after it is interrupted and received by the light receiving element 5, a transmission detector 9 transmits transmission trigger by the output signal of the light receiving element 5 at that time.  By detecting a rotational angle around the pan shaft 6 and a rotational angle around a tilt shaft 7 at the time of triggering the interruption trigger and the transmission trigger respectively by a rotational angle detector 10, and obtaining the mean value of the respective rotational angles by a midpoint computer 12, it is possible to determine a mechanism origin.

Abstract: PROBLEM TO BE SOLVED: To provide a constant voltage circuit reduced in the area of a capacitor for phase compensation by lowering a voltage applied across the capacitor for phase compensation even at the time of high voltage output and forming the capacitor for phase compensation by using a thin insulating film. SOLUTION: A phase compensating circuit 61 which constitutes the constant voltage circuit consists of the capacitor C1 for phase compensation, a P channel transistor(TR) P1, an N channel TR N2, and a constant voltage generating circuit which generates a constant voltage. Consequently, since the voltage applied across the capacitor C1 is Vgs(P1)+Vgs(N2), where Vgs(P1) and Vgs(N2) are the gate-source voltages of the P channel TR P1 and N channel TR N2, irrelevantly to an input voltage applied to an input terminal 1, the voltage is suppressed low.

Abstract: PROBLEM TO BE SOLVED: To prolong the life of a device to deodorize a smell from an air and make maintenance services feasible. SOLUTION: An air to be treated 4 which is sent from below a deodorization tower 1 comes into contact with a titanium dioxide particle 17 and consequently, an odoriferous gas component is adsorbed to be deodorized. The titanium dioxide particle 17 is received by a multi-stage dispersion shelf 13 through which an air is caused to pass from below and at the same time, is sent to a lower stage by gravity. During this process, the adsorbed gas component is decomposed by oxidation with a light energy generated by emission of a black light lamp I9 and the particle 17 is regenerated. This regenerated titanium dioxide particle 17 is conveyed to the dispersion shelf 13 on the top with the help of a particle conveying means 27 made up of an ejector.

Filed: 1992-05-07
Abstract: PURPOSE:To easily obtain a high tensile strength plated steel wire by subjecting a plain carbon steel wire to plating treatment after rapid cooling at the time of patenting, executing reheating at the time of plating diffusion and thereafter gradually cooling it. CONSTITUTION:A plain carbon steel wire contg. 0.65 to 0.95% C is charged to a patenting furnace and is hardened to generate pearlitic transformation. After the completion of the transformation, this steel wire is rapidly cooled to a room temp. Then, plating of Cu, Zn or the like is applied, and successively, the plain carbon steel wire is reheated to 500 to 600 deg.C in a thermal diffusing furnace to form the state of carbon as solid solution in ferrite in the structure into a one in which it is diffusible. After the reheating, the steel wire is gradually cooled to <=400 deg.C at 25 to 50 deg.C/sec cooling rate and is thereafter rapidly cooled to a room temp. Next, an oxidized film is removed by a posttreating apparatus, and it is coiled round a bobbin 2. Then, cold drawing is executed, and about 3.45 to 3.90 true strains are given thereto. In this way, the objective high strength plated steel wire having >=3500MPs tensile strength and provided with toughness can be obtd.

Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To improve both the running stability of a vehicle and the drivability by setting an optimum shift-up amount according to the size of the slip angle of a driving wheel. SOLUTION: This shift control device of an automatic transmission carries out a shift-up when the speed reduction slip ratio of a driving wheel is made larger excessively. The slip angle αr of the driving wheel is found (Step 30), the speed reduction slip ratio Sr of the driving wheel is inferred (Step 50), and it is decided whether the slip angle and the inferred speed reduction slip ratio are within a limit friction circle or not (Step 60). When the answer of the decision is YES, the speed change control is carried out by making the gear change step as an object gear change step (Step 130), and when the answer is NO, the above procedure is repeated as to the gear change step higher one step than the present change step, until the decision of YES is given.

IPC: G06F3/12
Filed: 1988-06-07
Abstract: PURPOSE:To easily input and output a sentence to and from a format form through a display screen by constituting a printer with an image scanner for a Japanese word processor and controlling and coupling an image file and a document file. CONSTITUTION:The printer 4 with the image scanner reads in a format and sends it to an image film generating means 12 to generate the image film. Then a sentence input control means 13 performs control by referring to the generated image film so that the document is not inputted on characters and lines in the image file, thereby generating the sentence file. When the document is printed on the format form, only the sentence file is printed. When, however, the format and sentence are outputted on blank paper at the same time, a file merging means 14 is put in operation to generate a merged image of the image file and sentence file on a memory. Then a merged image output means 15 is put in operation to sent the coupled image to the printer 4 with the image scanner, thereby printing the merged image.

Title: Low pressure electric discharge lamp
Inventor: SHIMIZU TAKAO
IPC: H01J61/067
Filed: 1992-06-02
Abstract: PURPOSE:To extend the life of a low pressure electric discharge lamp having a small diameter and used at low lamp current by employing tungsten as the material of a filament while plating the surface of the tungsten with a material which is chemically stable against electron emitting materials. CONSTITUTION:In a low pressure electric discharge lamp having a bulb 1 of inside diameter not more than 10 mm and used at lamp current not more than 40mA, tungsten plated at its surface with a material which is chemically stable against an electron emitting material 5 (e.g. platinum) is used as the material of a filament 6. The thermoelectron emitting material 5 is thereby shielded from the tungsten and as a result the reaction of the tungsten with the thermoelectron emitting material 5 can be restrained. Also, platinum does not react with the thermoelectron emitting material 5 or tungsten and hence generation of compounds having no thermionic emission is restrained and the rise of a cathode fall voltage during lighting of the lamp can be restrained and the loss of the electron emitting material 5 can be reduced.
