Title: Controller for flow rate of working fluid for power steering
Inventor: NARUMI TADATAKA
IPC: B62D5/07
Filed: 1979-12-27
Abstract: PURPOSE: To prevent the reduced flow rate of a pump from rising again due to the increase in load pressure, by providing a flow control spool valve with a variable orifice based on a control rod.  
     CONSTITUTION: Pressurized oil from a pump is entered through a supply passage 15 and divided to a send-out port 12 and a bypass 16. When the flow rate of the  pump is low, all the pressurized oil is supplied from the send-out port 12 to a power  steering gear because the bypass 16 is shut off by a spool valve 17. When the flow  rate increases, the spool valve 17 is moved to open the bypass 16 to set the pressure  on the front and rear ends of a throttle passage 28 and an auxiliary throttle passage  35 at prescribed levels. For that reason, the flow rate from the send-out port 12 is  reduced. When load pressure becomes high, the spool valve 17 is not displaced and does not shut off the bypass 16 because a control rod 27 is moved against a spring 30. For that reason, the flow rate from the send-out port 12 is not changed.

Title: X-rays ct apparatus
Inventor: FUJITA HIDEHIRO
IPC: A61B6/03
Filed: 1989-07-06
Abstract: PURPOSE:To make it possible to determine a photographing plane without giving an uneasy feeling or a fear feeling to an examinee and without accompanying cost-up by providing a window only at a position just above a dome and a rotation controlling device stopping a light projector above the window when rotation of an X-rays tube is stopped. CONSTITUTION:When photographing a certain photographing plane of an examinee 3 is finished, either one of a pair of light projectors 9a and 9b on both side of an X-rays tube 4 is controlled so as to be always stopped above a window 10 of a dome 8. Before photographing the next photographing plane, the photographing plane is determined by performing a light irradiation through the window 10 from the light projectors 9a and 9b under this condition. Then, this photographing plane is photographed by starting rotation of an X-rays photographing mechanism. As the window 10 is only provided just above the dome 8 and this window is covered by either one of a pair of the light projectors 9a and 9b, the rotation mechanism can not be seen from the examinee 3. Therefore, it is prevented to give an uneasy feeling or a fear feeling to the examinee 3 and in addition, as no special controlling mechanism is needed, cost-up is avoided.

Title: Multi-processing type counter
Inventor: MORIMURA HIROSHI
IPC: H03K25/00
Filed: 1984-08-22
Abstract: PURPOSE:To attain measurement of long time with a counter of less number of bits and to improve the accuracy at measurement for a short time by switching an adding value fed to an adder depending on the count. CONSTITUTION:When a signal is inputted to an input terminal 1, an output data of a RAM3 is inputted to an adder 4. When a signal from a selector 9 goes to logical 1, the data is increased by 1 and then stored again to the RAM3. Two signals having a different period are fed to input terminals 6, 7 of the selector 9, which is switched by the output of a comparator 8 to which the output of the RAM3 is inputted. That is, when the output of the RAM3 is smaller than a prescribed value, a signal with a short period is outputted and when larger, a signal with a long period is outputted. Thus, long-time measurement is attained with a counter of less number of bits and the accuracy at short time measurement is kept high.

Abstract: PURPOSE: To restrict fatigue due to preceding exposure of titanium dioxide, by adding one or more kinds of catechol and its derivatives to a photosensitive layer consisting chiefly of titanium dioxide and a resin binder.  
     CONSTITUTION: A photosensitive agent is dispersed into a resin binder by 35W 65vol% based on the binder, coated on a conductive substrate in a thickness of 10W 30μm, and dried to form a photosensitive material. At that time, one or more kinds of catechols represented by the formula (X is halogen, hydroxy, sulfo, nitro, or the like, and n is 0, 1 or 2) and these salts are added into the coating solution of the photosensitive material by 0.001W1mol% based on TiO 2 . The electrophotographic photosensitive material with these catecols added permits deterioration of charging characteristics and photosensitivity due to preceding exposure to be remarkably reduced.

Filed: 1989-07-05
Abstract: PURPOSE:To set a large amount of ink in the solid state at one time thereby to remove trouble in frequently supplementing the solid-state ink by providing an ink storage part for accommodating said solid-state ink therein, an ink melting part for melting said solid-state ink, and an adjusting part to adjust the feeding amount of said solid-state ink. CONSTITUTION:A printing head unit 1 is provided with an ink storage part 35 for storing powdered ink 17 discharged from a main storage part 21 and an ink melting chamber 39 having a heater 37 for melting said powdered in 17 of an appropriate amount. A valve mechanism part 19 consists of a plate-like valve operating plate 23 having a hole 22 and a leaf spring 25. The valve operating plate 23 is pushed by a push rod 31 against the leaf spring 25, so that the hole 22 overlaps with an opening portion 29. In consequence, the powdered ink 17 falls fown. Since the main storage part 21 can be formed separately from the ink storage part 35, it is not necessary to control the size of the main storage part 21. Accordingly, a large amount of the solid-state ink can be set at one time, thereby removing the trouble to supplement the solid-state ink.
