Title: Motor-operated cooking apparatus
Inventor: IKEDA MITSUYUKI
IPC: A47J43/046
Filed: 1990-01-26
Abstract: PURPOSE:To prevent vibration due to imbalance of a cutter and improve cutting efficiency by providing a lower cutting blade with an auxiliary cutting blade the end of which is located in the vicinity of the bottom surface of a container. CONSTITUTION:A container 15 is placed on a main body 1. A cutter 20 is attached to a joint 10 of an output shaft 8. By the operation of a switch 11, a motor 2 is driven to rotate a cutter 20, cut and cook objects to be cooked in the container 15. When vegetable and meat are minced and cooked, those materials are minced not only with upper and lower cutting blades 22 and 23 but also with a blade 24a of the rotary direction end side of an auxiliary cutting blade 24 so that cutting efficiency is improved and the materials are prevented from being flung in the circumferential direction and from leaking through a cylindrical body 16 out of the container 15. Because the auxiliary cutting blade 24 is formed with a weight approximately equal to the amount of imbalance between the upper and lower cutting blades 22 and 23, the cutter as a whole is almost balanced and vibration is prevented from being produced.

Title: Toroidal continuously variable transmission
Inventor: YOSHIDA MASAHITO
IPC: F16H15/38
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To improve efficiency of assembling work so as to lower a production cost while securing transmittable torque by preventing respective balls from falling off from respective spline grooves by means of a plurality of projections protruding to a pressing device side formed in a part matching the respective ball spline grooves. SOLUTION: In a locking ring 45, projection parts 47, 47 and arc parts 48, 48 connecting the base end parts of the adjacent projection parts 47, 47 together in the circumference direction are alternately continued in the circumference direction so as to form a ring shape as a whole. The locking ring 45 is provided with elasticity in the diameter shrinking direction by resiliency of the respective parts 47, 48. The inside diameter of the locking ring 45 in a free condition is smaller than the outside diameter of a locking groove forming part in a part of an input shaft.  In this way, respective arc parts 48, 48 constituting the locking ring 45 are locked in the locking grooves without any backlash by resiliency of the locking ring 45 itself, and under the locked condition, the respective projection parts 47, 47 are engaged with the opening parts of the respective groove parts, preventing the locking ring 45 from rotating with respect to the input shaft.

Abstract: PURPOSE: To form a sharp toner image without staining on the surface of a photoreceptor and to perform an efficient electrical transfer by previously electrifying the photoreceptor to a polarity opposite to that of a voltage applied to an electrode and attaining an exposure from the rear surface and development with insulating toner. CONSTITUTION: A voltage is applied from a power source to the conductive member 81 of the electrode 8 and a photoreceptor drum 1 is previously electrified to the polarity opposite to that of the applied voltage by the uniform exposure of a uniform exposure means 21 from the rear surface of the drum 1. An image exposure means 9 is arranged to face a developing sleeve 2 on the downstream side of an image exposing position P4 and an electrostatic latent image is formed on the photoreceptive layer of the drum 1 with an image exposure. Then, the reversal development of the surface of the drum 1 with the positively charged insulating toner carried by the sleeve 2 is attained in a developing region nearer to the downstream side than the contact position of the electrode 8 with the drum 1.  Thus, the drum can be stably electrified and a toner image without fogging is formed on the surface of the drum.

Filed: 1991-01-18
Abstract: PURPOSE:To prevent bugs moving on a recording sheet transport path from entering into a transfer device by ensuring that a high voltage power supply part is electrically connected to an insecticidal mesh part 4 at a time than when a control circuit part is activated to print data. CONSTITUTION:A high voltage output from a high voltage power supply part 9 is divided using a voltage dividing resistor 11 and the divided voltage is applied to an insecticidal mesh part 12. The applied voltage is a voltage which can generate an electric discharge between an insecticidal mesh high voltage part 12a and an insecticidal mesh gland part 12b but to such an extent that the voltage is high enough to kill bugs. If bugs entering from a recording sheet cassette 1 or a recording sheet discharge aperture 10 come in contact with the insecticidal mesh high voltage part 12a and the insecticidal mesh gland part 12b simultaneously when they move in a narrow transport path and passes through the insecticidal mesh part 12, the bugs become electrocuted or thrown into a syncopic state due to a high voltage applied to the insecticidal mesh part 12. Subsequently, the bugs are prevented from finding their way into a transfer device 6.

Filed: 1978-02-14
Abstract: PURPOSE: To make it possible to distinguish clearly between quantitative sale and numerical that judging from the existence of a decimal point, and also to sum easily the number of processes by changing addition contants to a summing memory unit by discriminating between a registered number containing a decimal point and that without it.  
     CONSTITUTION: Decimal-point memory unit 24 is stored with the output of decimal- point key 12 at the time of registration and discriminates whether the registered number has a decimal point or not, and number register 4, which sums and stores the number in case of numerical sale and one regardless of the quantity in case of quantitative sale, sums and stores the contents of "1"-signal generator 52 or 2nd register 22 by using adder 51. In general, a decimal point is contained in many cases of the quantitative sale and even when the number happens to be an integer, a decimal point is added; and then, printing is done discriminating between a numeral containing a decimal point for the quantitiative sale and that without a decimal point for the numerical sale. As a result, registration errors are reduced and the conventional problem of forgetting depressing a discrimination key for the discrimination between quantitative sale and numerical sale is solved.
