Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To reduce a calibration error by increasing the capacitance of a foil electrode so that an error between the apparent series capacitance inside a calibration equipment and an actual series capacitance is within a target range. SOLUTION: A foil electrode is provided at an insulation connection part insulation cylinder of a cable line, and a pulse is fed into the cable line via the foil electrode.

Title: Inhibitor of body smell by sweat
Inventor: YAMAMOTO TAKASHI
IPC: A61Q15/00
Filed: 1991-10-08
Abstract: PURPOSE:To obtain an inexpensive and safely usable inhibitor of body smell by sweat capable of directly acting itself on the body or mixing in a bathing agent, a body shampoo, etc., for use. CONSTITUTION:An inhibitor of body smell by sweat is obtained by concentrating a mixed aqueous solution of aluminum sulfate with potassium sulfate according to a usual technique, producing potash alum, heating the potash alum, expanding the potash alum, eliminating water of crystallization, producing white and porous burnt alum and using the resultant burnt alum as the inhibitor. The resultant inhibitor is dissolved in water at about 15-20 deg.C and applied to the body. Thereby, blood vessels are contracted by astringent action and secretion of sweat is suppressed to dry the body surface. As a result, fatty acids contained in secretions are nearly eliminated to suppress the occurrence of malodor by their decomposition.

Filed: 1989-11-07
Abstract: PURPOSE:To achieve a longer life of a semiconductor provided at the tip of an inserting section by detecting temperature of the tip of the inserting section from a difference between a signal level of a optically black part and a signal level of a part not attributed to an output of an optoelectro element. CONSTITUTION:As a temperature of a solid image sensor 13 rises, a signal level of a image signal part at an OB section(optical black section) 32 and an incoming light detecting section 31 is increased by a fixed value by a dark current generated in a photodiode. But at a dummy section 33c, there is no increase by the dark current as the signal level is not attributed to an amount of an electric charge generated in the photodiode. As a result, a difference  in the signal level is generated between the dummy section and the OB section at an output of a sample holding circuit 36 and this value is given as output of a subtraction circuit 39 as it is. Therefore, as the temperature of the solid image sensor 13 exceeds TO in the drawing, the output of the subtraction circuit 39 surpasses a threshold Vs of a comparator circuit 41 and a temperature rise detection signal 24 is outputted to a gain increasing circuit 23. Then, a signal amplified twice is inputted into a dimmer circuit 27 and a control circuit 22 halves a quantity of light incident into a light guide 16.

Abstract: PURPOSE:To obtain a toner having characteristic for triboelectric charge having stable negative polarity after long time use or against environmental changes, and to form a picture having a good quality as good as an initial picture by incorporating a specified organoboron compd. into a toner as negative charge controller. CONSTITUTION:In a stage for developing a latent image by feeding a one component toner consisting primarily of a colorant, binder resin, and a positive or negative charge controller onto the surface of an electrostatic image carrier, an organoboron compd. expressed by the formula I is used as controller of negative charge in the toner. In the formula I, X<+> is a cation. Such negative charge controller can be synthesized by a conventional means, which can be used singly or in combination with >=2 kinds of toner. Moreover, it may be used together with other charge controller. Thus, a good picture having picture quality as good as that of an initial picture can be formed after a continuous copy without deteriorating the characteristic for triboelectric charge of a toner due to long time use or environmental changes.

IPC: B60K23/08
Filed: 1985-12-23
Abstract: PURPOSE:To prevent large load from being imposed on a power transmission system, by constituting a device in making a selector device interlock with a sub-gear shifter so as to be selected to four-wheel drive with low-speed driving select operation, in case of a device, bearing the above caption, having the 2WD-4WD drive selector device and the sub-gear shifter. CONSTITUTION:When a shift arm 47 is selected from a neutral position as in a dashed line to a low-speed driving state shown in a two-dot chain line, an extension part 47a of the shift arm 47 is engaged with an engaging piece 71 of a transfer fork 54 in the midway, making this transfer fork 54 forcibly into slide motion. With this operation, a selector device 30 comes into a 4WD drive state shown in the two-dot chain line. In this case, when a sub-gear shifter 31 is in a high-speed driving state, the transfer fork 54 is movable without being checked by the engaging piece 71, whereby selection of 4WD and 2WD can be freely performed by a selector switch 69. With this constitution, such a fear that large load might be imposed on a transmission system is preventable.
