Abstract: PROBLEM TO BE SOLVED: To obtain a thermosensitive recording material of a level for satisfying characteristics such as excellent thermal stability of an image, color developability, white ground coloring and the like by incorporating at least one type of a specific pyrazole derivative as an electron acceptable compound. SOLUTION: A thermosensitive recording layer is provided by incorporating at least one type of an electron donative normally colorless or pale color dye precursor and a pyrazole derivative represented by a formula of an electron acceptive compound (wherein R<1> , R<2> are each a phenyl group or naphthyl group which may have a substituent, and R<3> is a hydrogen atom, an alkyl group or a phenol group which may having a substituent), dispersing them in a binder and coating it on a support. The layer is heated by a heat head, a hot pen, or a laser beam to instantaneously react the precursor with the acceptive compound, thereby obtaining a recording image. A pigment, a sensitizer, an antioxidant, and a sticking inhibitor are added to the recording layer as needed.

Abstract: PROBLEM TO BE SOLVED: To form full-color images having high image quality and to obtain developers having high reliability by constituting the toner developers of specific color toners and black toners. SOLUTION: This developer is the plural toner developers used for a color copying machine. The toner developers are composed of the color toners having Wadells operational sphericity ψ of >=0.8, volumetric average rain size Dv of 4 to 8μm and a fluctuation coefft. (standard deviation/Dv) σ of <=35% and the black toners having the Wadells operational sphericity smaller than the Wadells operational sphericity of all of these color toners and the large volumetric average grain size.  In such a case, the sphericity ψis expressed by ψ = (the diameter of the circle of an area equal to the projection area of particles)/(the diameter of the min. circle circumscribing the projected image of the particles) and may be easily calculated by taking a suitable amt. of the toners on sliding glass, magnifying the images thereof with a microscope and making measurement with arbitrary 100 pieces of the toners.

Filed: 1989-04-13
Abstract: PURPOSE:To simplify the structure and to reduce manufacturing cost by charging at least two backup power sources with regenerative power to be fed from a regenerative switch circuit through an inverter main circuit upon interruption of power supply from an AC power source. CONSTITUTION:A power interruption detecting circuit 41 detects power interruption and provides power interruption detecting signals to a control circuit 37 and a regenerative switch circuit 39. The control circuit 37, which is fed with power from a battery 38 for control circuit, gradually lowers the frequency of control signal being fed to an inverter main circuit 35 such that the frequency of the control signal will be lower than the frequency corresponding to the rotation of a motor 31. Consequently, regenerative power is fed from the motor 31 through the inverter main circuit 35 to the DC source line 34 side. The regenerative switch circuit 39 conducts between input and output terminals based on the power interruption detecting signal. By such arrangement, batteries 49a, 49b for bearing are fed with regeneration power from the inverter main circuit 35 through the regenerative switch circuit 39 and charging operation is started.

Abstract: PURPOSE:To improve workability and safety of an elevator motor by changing speed of the elevator motor in three stages of high, medium and low by means of a three stage switch and, in addition, by setting the respective speed arbitrarily by means of respective elevating speed regulators. CONSTITUTION:After low, medium and high speed regulators 4, 5 and 6 have been set preliminarily, an ascending push button PB1 of a three stage switch 3 is pressed to the first step position during ascending of a hung cargo. Then, a photo sensor PT2 only is operated, and an interface 12 makes an ascending contact point X1 and a first step contact point X3 switched on. For this reason, an electric motor M is rotated in the ascending direction at a low speed set to an invertor INV by a regulator 4. Next, when the button PB1 is pressed to the second step position, both of photo sensors PT1 and PT2 are operated, and the interface 12 makes the contact point X1 and a second step contact point X4 switched on. As the result, the electric motor M is rotated in the ascending direction at a set medium speed. Similarly, when the button PB1 is pressed to the third step position, the electric motor M is rotated in the ascending direction at a set high speed.

Abstract: PURPOSE: To make it possible to know the item to be performed at that time by generating the infdrmation in the memory and the signals for the time, at which the actual time and the time in the memory becomes coincident.  
     CONSTITUTION: When a watch 5 indicates the same time as that which is preset in a time memory unit 9, a time coincidence detecting unit 6 checks this to generate the signals indicating the coincidence and the signals for regenerating the information symbols. An output unit 7 generates the mechanical sounds in response to the former coincidence signals and takes out the preset information, which is fed from an information memory unit 8, in response to the latter signals. Incidentally, a normal TV receiver set is used to display the stored information in an image in an overlapped manner. Moreover, the stored content is forcibly displayed in the portion other than the image, and the mechanical sounds may be generated. Thus, it is possible to reliably know what is to be done at the informed time.
