Title: Valve timing regulating device
Inventor: USHIDA MASAYASU
IPC: F01L1/344
Filed: 1993-05-19
Abstract: PURPOSE:To maintain a valve timing stably against driving torque reaction by shutting out feed and discharge oil into and out of a delay angle side oil pressure chamber as well as supplying a prescribed amount of oil to a advance angle side oil pressure chamber when a cam shaft side member is maintained in a desired position opposing the crank shaft side member. CONSTITUTION:When a constant current is supplied from a control circuit 9 to the coil part 21 in a yoke 20 in a control valve 10, suction force for sucking a moving core 22 is balanced with energizing force of a spring 25, and a spool 24 is maintained in a constant position in a sleeve 23. When a cam shaft 1 is rotated relatively to a delay angle side in relation to a timing pulley 5, the amount of oil discharged from an advance angle side oil pressure chamber 14 per unit time is restricted by a throttle 40 arranged in an oil pressure releasing passage 15a communicated with the control valve 10. A moving speed in advance angle side oil pressure chamber 14 direction of a hydraulic piston 8 is restricted. It is thus possible to increase momentarily moving speed of the hydraulic piston 8 so as to prevent generation of moment ary oil supplying shortage in the delay angle side oil pressure chamber 12.

Title: Method and device for electrophotography
Inventor: RAN MUNEKI
IPC: G03G13/10
Filed: 1981-07-27
Abstract: PURPOSE:To facilitate reversal development, and to obtain a clear image by using a toner having the same polarity as parts of a photoreceptor which are not exposed, and utilizing leakage magnetic flux appearing at the photoreceptor for the reversal development. CONSTITUTION:A toner to be used has the same polarity as parts of a photoreceptor which are not exposed. The photoreceptor is charged uniformly by a charger, for example, positively and is exposed to an image by a laser beam to form an electrostatic latent image. In this state, lines of electric force (leakage magnetic flux) shown by broken-line arrows are obtained on the surface of the photoreceptor 3. When the positive toner is stuck to the surface, the toner are stuck only where there is no charge owing to the exposure, and no toner is stuck to no-image-line parts where there are charges, thus performing reversal development. The electric field operates intensely upon the edge circumference of the image to increase the toner density, obtaining the image having superior contrast.

Abstract: PURPOSE:To give a blood circulation promotion and an emotion tranquilizing work to a user with a massage corresponding to the slight friction of the massage by means of a hand technique by moving a pressure body for pressing a body formed of an air bag in a direction along the body. CONSTITUTION:For a massage machine, a mat 3 is laid on a floor surface, and traveling blocks 1 and 1 are made to travel in a condition in which the user lies on his back and on his face on the mat 3 or in a condition in which he is seated. Along with the traveling, a pressure body 20 which is the spherical air bag to be rotable in a main block 2 is moved along an upper surface to the body, and at such a time, a load by a weight 23 and a battery 27 is given to the body upper surface, simultaneously, the body 20 is rolled on the body upper surface, and a stroking massage is executed. Since the main body block 2 is moved up and down according to the irregularity of the body upper surface, the same load can be given to each part of the body upper surface, and the load optimum for the user can be set by mounting and removing a weight 3. Since a backbone cannot be bent because the body escapes as the conventional massage machine, even when the pressure is made strong, a stimulus is not strong, and a soft and comfortable stimulus feeling can be obtained.
