Title: Erroneous erasure preventing device for rewritable recording medium
Inventor: OKAWARA KOJI
IPC: G11B7/0055
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous erasure by registering TOC information of a fixed recording medium in a memory, checking TOC information read out of a recording medium with the TOC information registered in the memory, and inhibiting recording in the recording medium when both information coincide with each other. SOLUTION: TOC information on a rewritable disk is, recorded in a protect disk memory 11A set in a RAM via a microcomputer (μ-COM) 10. When COM 10 has loaded a recordable disk, it reads in TOC information recorded on the disk and writes it in a RAM 11. The COM 10 checks the TOC information. with TOC information stored (registered) in the memory 11A, and when the same information exists therein, the COM 10 displays on a display part 13 that recording is impossible. Moreover, the COM 10 does not execute recording operation even if instructed to start recording from a key input part 12. Thus, a simple configuration makes it possible to avoid erasure recorded contents by misoperation.

Title: Ion concentration analyzer
Inventor: YAMAGUCHI SEIJI
IPC: G05D21/00
Filed: 1987-11-10
Abstract: PURPOSE:To measure ion concentration with high accuracy by detecting a change in ion concentration due to the evapolation of water in a calibrating solution from a change in conductivity and correcting a practical ion concentration measurement result. CONSTITUTION:A conductivity detector 13 is prepared for a low concentration calibrating solution 7 and a conductivity measuring circuit 14 and a correcting arithmetic circuit 15 are added to an ion concentration arithmetic circuit 12 as electric circuits. The circuit 14 measures the whole conductivity of the solution 7 by a detecting signal obtained from the detector 13 and the circuit 15 corrects the output of the circuit 12 based on the change of conductivity with the lapse of time and outputs an accurate ion concentration. Even when the ion concentration of calibrating solutions 7, 8 is changed due to water evapolation, the ion concentration of a sample solution 6 can be accurately measured.

Title: Blow molder
Inventor: SATO YUKIO
IPC: B29C49/78
Filed: 1987-11-09
Abstract: PURPOSE:To stabilize the wall thickness, shape, weight and the like of a blow molded item and consequently obtain a high quality product by a method wherein the diameter of a parison is directly measured by a measuring means. CONSTITUTION:When the diameter of a parison 13 reaches the predetermined value, light beam sent from light emitting diodes to photoelectric tubes 22 are interrupted and the resultant signal is inputted to a parison diameter measuring apparatus 21. As a result, the arrival of the diameter of the parison 13 to the predetermined value is detected. Further, the signal from the measuring apparatus 21 is inputted to a blowing pressure controlling device 20, which controls a pressure control valve 19. Thus, the blowing pressure is lowered so as to prevent the diameter of the parison 13 from expanding beyond the desired one. Consequently, the diameter of the parison 13 at pre-blowing becomes constant, even when the environmental conditions such as the temperature of the outside air, the viscosity of resin and the like change. Next, a signal is sent to the mold clamping circuit of a blow molder in order to start the clamping of a mold. Further, the parison is blown by stronger pressure and, after that, cooled in order to obtain a blow molded item 23. Thus, a parison 13 with stable diameter is produced at pre-blowing.

CONSTITUTION:A solenoid valve on/off control means 25 opens the first solenoid valve 11 under an assumption that a refrigerant pump 10 compresses liquid in the case that a cooling mode sensing means 19 detects cooling state and a value inferred by a fuzzy inference means 4 is 1, performs a repetitive on/off of the third solenoid valve 13 and in turn opens both solenoid valves 11, 13 under an assumption that the refrigerant pump 10 does not perform any liquid compression when the result of fuzzy inference is not 1. At this time, the second and fourth solenoid valves 12, 14 are closed. When the heating mode is judged and the result of fuzzy inference is 1, the fourth solenoid valve 14 is opened and the on/off of the second solenoid valve 12 is repeated. When the result of the fuzzy inference is not 1, the solenoid valves 14, 12 are opened. At this time, the first and third solenoid valves 11, 13 are closed. Liquid refrigerant for the refrigerant pump 10 is restricted under the most suitable manner.

Title: Method of measuring endotoxin in fat
Inventor: KISHIMOTO YOKO
IPC: G01N33/579
Filed: 1994-10-21
Abstract: PURPOSE: To enable handy and accurate measurement of endotoxin in fat by extracting and removing the fat using an water-insoluble organic solvent to perform a colorimetric determination of a water phase after the fat is dispersed into water to perform a detection reaction of the endotoxin. CONSTITUTION: A dispersion liquid in which fat in a surfactant or the like as natural animal and plant oils is dispersed in a distilled water or the like undergoes a detection reaction of endotoxin such as enzyme reaction based on a horseshoe crab amebocyte lysate component and a coloring reaction or the like with a diazotation reagent. The water dispersion liquid after the reaction is turbid because of the fat contained and hence, accurate colorimetric determination is impossible even if by measuring absorbance. To solve this problem, prior to the colorimetric determination, a water-insoluble organic solvent such as chloroform is added and the organic solvent is separated from a water phase by a centrifugal separation operation. Then, the colorimetric determination is carried out for the water phase after the oily substance is detected and removed.

Filed: 1993-11-12
Abstract: PURPOSE: To improve the cleaning efficiency and the cleaning reliability of a surface cleaning device for removing residual toner from a surface and to improve the wear and abrasion resistance of a cleaning blade. CONSTITUTION: This belt/blade-type surface cleaning device is provided with a belt 18 where plural blades 19 are formed.

IPC: F16C17/24
Filed: 1988-11-11
Abstract: PURPOSE:To detect any bearing abnormality at an early stage by connecting each pair of resistors, condensers and coils to a parallel circuit being connected to an amplifier amplifying an electric current out of a generator, while setting up the paired coils in front and in the rear of a bearing sliding surface, and detecting any current variations in the parallel circuit due to an impedance variation in the front coil. CONSTITUTION:A parallel circuit 27 is connected to an amplifier 26 amplifying a high frequency current of a generator 25, and each pair of resistors 28a, 28b, condensers 29a, 29b and coils 30a, 30b are all connected to this parallel circuit in series. When oil film temperature on a bearing sliding surface is suddenly changed by something wrong in a bearing, impedance of the front coil 30 proximate to an oil film is suddenly changed as well. In this case, since it takes much time for heat conduction, impedance of the rear coil 30a is not changed at all, and a current of the parallel circuit 27 is varied to some extent by impedance differences, then this variation is detected by an amplifier 31, thus a demodulator outputs it. Therefore any bearing abnormality is detectable at an early stage.
