Inventor: DATE MUNEHIRO
IPC: G01N11/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To an apparatus and a method, for the evaluation of the characteristic of an emulsion, in which the physical property of the emulsion having a correlative property with the sensitivity of a human being can be measured with high reliability and with good reproducibility and in which the characteristic of the emulsion can be evaluated objectively instead of a sensory analysis which depends on the sensitivity of the human being as in the case of cosmetics. SOLUTION: A moving plate 12, a probe 14, an elastic member 16 whose lower end is fixed to the probe 14 and which is extended up and down, a probe pressing device 18, a back and forth moving device 20 and a measuring device 22 which measures a sliding force acting on the probe 14 are provided. The rear surface of the probe 14 is formed on an arc face around the horizontal axis (Z) at right angles to the sliding direction of the probe 14. Thereby, even when the elastic member 16 is elastically deformed by a sliding resistance (R) so as to tilt the probe 14, the shape in the contact part of the arc face of the probe 14 with the moving plate 12 is not changed. A vertical force (F) which acts during this time is constant. The probe 14 is not hooked by its back and forth moving operation because it has the arc face.  Consequently, the characteristic of an emulsion can be measured on the basis of a change in the sliding force which is measured.

Title: Instrument for measuring residual chlorine
Inventor: NISHIKATA SATOSHI
IPC: G01N27/416
Filed: 1989-04-04
Abstract: PURPOSE:To correctly measure the concn. of a free residual chlorine by measuring the change in oxidation reduction potential (OPR) while injecting chlorine into a sample, then making decision as to whether the state is before or after a discontinuous point. CONSTITUTION:Whether the sample 6 is before or after the discontinuous point is decided by injecting the chlorine 7 into the sample 6, measuring the ORP and making decision that the sample is before the discontinuous point if the ORP changes rapidly and after the discontinuous point if the ORP does not rapidly change; therefore, whether the sample is before or after the discontinuous point is decided correctly without being affected by the fluctuation in the ORP value of the sample 6 itself and the drift and temp. of an ORP meter 2. Since only the residual chlorine of a bond type exists in the sample if the sample is before the discontinuous point, the free residual chlorine is made 0. Only the residual chlorine of a free type exists therein if the sample is after the discontinuous point and, therefore, the measured value obtd. by a polarograph method is determined as the concn. of the free residual chlorine, by which only the free residual chlorine is measured. The exact measurement of the free residual chlorine is possible in this way.

Title: Image forming device
IPC: G02B26/10
Filed: 1992-03-10
Abstract: PURPOSE:To attain multiple objective signal generation processing with a single photodetecting mechanism by executing control so as to direct the transfer destination of the output of an optical signal outputted from a detecting means to one of signal generating means, by means of an output control means. CONSTITUTION:An optical fiber cable 7 transmits light beams converged by a lens 6 to the optical sensor 802 of a detector 801 and the detector 801 amplifies the optical signal detected by the sensor 802, and outputs it to the multiple system of the processing systems of a BD detecting circuit 803 and an AF circuit 804. In this way, when the detector 801 consecutively detects the light beams with which a photosensitive body 4 is scanned/exposed, the output control means (switches 808 and 809) executes the control to direct the transfer destination of the output of the optical signal outputted from the detector 801, to one of the signal generating means (either of the BD detecting circuit 803 and the AF circuit 804). Thus, the multiple objective signal generation processing can be attained by the single photodetecting mechanism.

Title: High voltage generating transformer device
Inventor: KOIZUMI HIROHISA
IPC: H01F19/04
Filed: 1989-04-05
Abstract: PURPOSE:To reduce the crest value of the pulse voltage a the finishing part of winding on each layer by a method wherein the electrostatic capacitance between the windings of the adjacent layer is provided in such a manner that the value in the vicinity of the starting end of winding is made larger than the value in the vicinity of the finishing end of winding. CONSTITUTION:When an impulsive current is made to flow on the primary side, each pulse voltage source (en) generates almost same magnitude of pulse voltage respectively. The voltage of each pulse voltage source (en) is added, and it is included in the capacitors C1 and C2 at the ending and the starting of winding. As the dielectric constant of synthetic resin 14a and 14b is in the relation of 14a<14B, the magnitude relation between C1 and C2 is C2<C1. To be more precise, the electrostatic capacitance between the adjacent layers on the part in the vicinity of the finishing end of winding is larger than that of the starting end of winding. The quantity of electric charge, which is instantaneously charged on each of the capacitors C1 and C2 when pulse is generated, is almost equal, and the more the electrostatic capacitance becomes larger, then more the voltage at both ends becomes small. To be more precise, voltage is in the state wherein it is hardly boosted in the finishing end of winding than the starting end of winding. Accordingly, if the electrostatic capacitance between the adjacent layers in the vicinity of the finishing end of winding, is increased against the conventional electrostatic capacitance, the crest value of the pulse voltage of that part can be reduced.
