Abstract: PURPOSE:To make it possible to detect with high accuracy by using an ultrasonic transmitter and its receiver which have been provided so as to be opposed on the surface of an object to be detected, utilizing an ultrasonic dead phenomenon, and detecting the surface position. CONSTITUTION:An ultrasonic transmission element 1 and its receiving element 2 are opposed on the surface of an object to be detected 3, and are arranged at a constant interval L1. When a distance D1 between the surface of the receiving element 2 and the surface of the object to be detected 3 is varied, the output of the receiving element 2 is varied pulsatively, and when said D1 is between a distance d1 and d2 (about 10mm.), an ultrasonic dead phenomenon is caused, and the output is lowered abruptly. Also, even when it is between a distance d3 and d4 (about 28mm.), the dead phenomenon is caused, as well. When said phenomenon is utilized, it is also possible to detect with high accuracy a water-level of an automatic equipment which maintains a water-level varied in the vessel at the position between d1 and d3.

Abstract: PURPOSE: To make it possible to maintain the high image quality of a first toner image on a photosensitive drum, to separate and recover first toners without accumulating these toners in a second developing device in case the first toners intrude into this second developing device and to easily obtain two-color images having high quality without affecting the second toner image by the first toners. CONSTITUTION: A method for developing magnetic one-component toner with alternate electric fields without contact by using magnetic toners (second toners 19) is adopted for second development. The positions on a triboelectrification series are made more reverse polar backward in order of the second toners 19 > an elastic blade 12 > the first toners 18 by adjusting the kinds of the binders of the first toners 18 and the second toners 19, the kinds of external additives and the material of the elastic blade 12 of the second developing device 6, by which the average electrostatic charge quantity of the first toners 18 after the intrusion into the second developing device 6 is made smaller than that of the second toners 19.  As a result, the mirroring power of the first toners 18 intruded therein to the developing sleeve 7 of the second developing device 6 is weakened and, therefore, the first toners 18 are suspended by the developing bias in the developing region thereof and are separated and discharged outside the second developing device 6.

IPC: H02P7/298
Filed: 1982-03-17
Abstract: PURPOSE:To obtain a brake torque in low speed range by employing regenerative braking and counterelectromotive force control by field inversion. CONSTITUTION:A speed control amplifier 2 outputs a deviation signal between the speed command of a speed setter 1 and the speed feedback of a rotating speed detecting tachometer generator 8, and a motor control amplifier 3 controls a one-side full-arm thyristor converter 4 in response to the deviation signal.

Title: Hanger
Inventor: TSUKADA YUZURU
IPC: B66C1/66
Filed: 1995-03-02
Abstract: PURPOSE: To prevent a subject to be hoisted from being damaged owing to opening of a hook by causing a locking step provided at the top of a holding rod to be engaged with an end face provided at the top of a guide plate during hoisting, and restraining the force of the hook of the holding rod to move outwards time force resulting from gravity. CONSTITUTION: This hanger is raised by a chain hoist when inserted into a subject 15 to be hoisted. A hanger support plate 6 first rises and tows a holding rod 1 upward via a ring 5. This towing force causes the lower end of the holding rod 1 to rotate via a shaft 4 in such a way as to bulge outwards, and a hook 2 at the lower end of the holding rod 1 is engaged with the inside wall of the subject 15 to be hoisted, thereby hoisting the subject 15 upwards. Also, a locking step 12 provided at the top of the holding rod 1 is engaged with a locking end face 13 provided at the top of a guide plate 10, and this engagement restrains the force of the hook 2 to move outwards, and limits the pressing forces between the hook 2, the subject 15 to be hoisted, and the inside wall, thereby preventing damage to the inside wall and the hook 2.

Title: Automatic thread fastening machine
Inventor: OTSUKA YOSHIKUNI
IPC: B23P19/06
Filed: 1986-02-27
Abstract: PURPOSE:To obtain smooth release of engagement between a screw head and a driver bit in an automatic thread fastening machine for a cross-recessed head screw, hexagon socket head screw or the like by composing the machine of a drive clutch, a driven clutch, a cam groove cylinder, a driver bit with a pin, and others. CONSTITUTION:When a rotating drive source 6 is actuated, a screw 22 is pressed against a work 33 by a driver bit 18, causing relative movement between a driver body 21 and the driver bit 18. This action causes engagement between a claw driven clutch 9 and a claw clutch 8 to thread the screw 22 onto the work 33. Then, when the driver body 21 is moved upward, the claw driven clutch 9 is pressed against a fixing member 11 to be fixed to the driver body 21. Further upward movement causes movement of a lock pin 20 along a cam groove 17, so that the driver bit 18 is reversely rotated. This permits smooth release of engagement between the driver bit 18 and the head of the screw 22.
