Title: Article lending device
Inventor: NAKAGAWA MASANAO
IPC: G07F7/08
Filed: 1988-06-06
Abstract: PURPOSE:To permit discount of rent or account at late days to customers whom many articles are frequently lent to by providing a card with an accumulation area where the number of all lent articles and the frequency in lending of a customer are accumulated and stored and updating contents of the accumulation area by an adding means at the time of lending articles. CONSTITUTION:With respect to the lending operation, a member card 70 is inserted, and a card reader 26 reads out the number of cassettes lent at present and compares it with a limit number of cassettes to store the number of lent cassettes in a memory 21. If the number of cassettes lent at present is said limit number, lending is rejected, and the customer gives up borrowing to depress an end key or returns one of cassettes which he borrows at present. When the number of cassettes lent at present is smaller than said limit number, the slot selection input due to a cassette selecting key 25 is accepted. When the slot is effective, the cassette selected by a handller of a video cassette handling part 29 is taken out of the slot. The account processing of rent is performed in a cash handling unit 27 and the cassette is delivered to the customer. The member card 70 is returned to the customer after update like addition of contents of a storage area 76 of the number of all lent books and a storage area 77 of the number of cassettes lent at present.

Title: Engine controlled in number of operating cylinders
Inventor: FUJII TAKASHI
IPC: F02D41/02
Filed: 1981-09-03
Abstract: PURPOSE:To prevent previously misfire caused upon switching and engine stall, by a method wherein a means, deciding that the revolution number of an engine is lower than a predetermined revolution number and stopping the switching of the number of operating cylinders is provided, when the number of operating cylinders is switched in accordance with the load of the engine. CONSTITUTION:Even if an operating condition such as the load or the like is deviated from a partial cylinders operation zone, it is limited that the partial cylinders operation is returned to an all cylinders operation only when the revolution number N is higher than a preset revolution number N3, while, in the other cases, the partial cylinders operation is continued and the switching of the number of operating cylinders is not effected even if the output of an AND circuit 31 which is the set input of a flip flop 33, is switched from H to L. On the contrary, when the all cylinders operation is shifted to the partial cylinders operation, if the other conditions for the partial cylinders operation are satisfied, the switching of the cylinder number is never effected since the output of the AND circuit 31 which is the set input of the flip flop 33 is always on the L level in the zone in which the engine revolution number N is lower than the preset revolution number N3.

Inventor: KANBARA TAKASHI
IPC: H02M7/48
Filed: 1993-06-10
Abstract: PURPOSE:To provide a highly efficient downsized power supply by reducing the switching loss of a switching element at a voltage converting section. CONSTITUTION:A DC power supply 5 is connected with a flyback voltage converting section 1 having the output side connected, through a diode D1, with a capacitor C, a load circuit 2, and a series circuit of resistors R1, R2 for detecting the voltage Vc across the capacitor C. The capacitor C has a low capacitance for allowing pulsation of the voltage Vc. When a control circuit 3 detects that the pulsating voltage Vc across the capacitor C dropped below a predetermined level based on the voltage divided by the resistors R1, R2, a switching element Q0 at the voltage converting section 1 is turned OFF. This circuitry can reduce the switching loss, at the time of turn OFF, of the switching element which functions at high frequency in order to pulsate the voltage across the capacitor C.

Abstract: PURPOSE: To change the elastic coefficient of rubber continuously and enable to equalize the elastic coefficients of rubber-made supporting legs of a vibration testing stand, for example, easily by a method wherein a solenoid coil is provided around a rubber product mixed with pure soft iron powder and electricity is conducted through the solenoid coil.  
     CONSTITUTION: A proper amount of pure soft iron powder is kneaded into a rubber material, thereafter, the material is formed through a known working process to make a rubber-made supporting leg 1. This rubber-made supporting leg 1 is fixed to a lower surface of a test table 2 and a floor surface 3, thereafter, a solenoid coil 4 having the same specification is provided around each supporting leg 1 and an electric source is connected independently to the coil to conduct an electricity, then, the pure soft iron powder is magnetized and is attracted each other, therefore, the leg 1, which was soft when the electricity is not conducted, is changed into the leg of a hard quality. Accordingly, when a sliding transformer or the like is connected between each coil 4 and the power source to increase an electric current from zero to some value gradually, the elastic coefficient of each rubber-made supporting leg 1 is varied within an elastic limit thereof. However, when the current is returned to zero, the magnetism is not remained, therefore, the quality of the leg 1 will never be changed.

IPC: B23P15/28
Filed: 1995-05-15
Abstract: PURPOSE: To provide a cutting tool having the excellent abrasion resistance by specifying the ratio of the volume rate of the cored structural hard phase, which is occupied in the hard phase inside the predetermined distance from the flank, and the volume rate of the cored structural hard phase, which is occupied in the hard phase inside a little distance from the flank. CONSTITUTION: Volume rate of the cored structural hard phase (a)-1 -3, which is occupied in the hard phase at 1mm from the flank, is expressed with A, and volume rate of the cored structural hard phase (a)-1 -3, which is occupied in the hard phase inside at 0.01mm from the flank, is expressed with B, and B/A exists in the range of 1.2-10. In the case where this B/A is less than 1.2, there is not a great difference between this tool and the ordinary cutting tool made of the titanium carbonitride group cermet, and the characteristic of the cutting tool is inferior to the ordinary cutting tool. In the case where B/A exceeds 10, skeleton of the surface develops more than the necessity. Consequently, B/A:1.2-10 is determined. More desirable range of B/A is 2.0-5.0.

Title: Automatic tension control-type drawing drum
Inventor: KAWAKAMI NOBUYUKI
IPC: B65H63/00
Filed: 1981-09-08
Abstract: PURPOSE:To check overspeed of an electric wire by increasing tension when the draw-out speed of the electric wire is detected to be more than a predetermined value. CONSTITUTION:An overspeed checking mechanism comprises a tachogenerator 11 for generating a speed signal for drawing out an electric wire according to the condition of rotation of an output shaft 4b of a differential gear 4, and an overspeed setting device 13 for setting a check starting speed. When the draw- out speed is more than the check starting speed S of the overspeed setting device 13, the potential of the output of an amplifier 12 is negative relative to the potential of the overspeed setting device 13, so that an electric current flows through a diode 15 as indicated with an arrow. Therefore, the potential is lowered on the input side of a power amplifier 10 to be shifted to a constant tension control system under high tension, resulting in that the electric wire is controlled to reduce the speed. Thus, the draw-out speed of the electric wire is kept from overspeed.
