Title: Power steering device
Inventor: OOSAKI HIROSHI
IPC: B62D3/08
Filed: 1980-01-17
Abstract: PURPOSE: To make the piston and clamp compact and of light weight by providing circular concave parts which eliminate the interference of the bending parts of a ball tube and tube inserting holes in the piston part.  
     CONSTITUTION: Holes 12 are provided in the piston 5 for attaching a ball tube 9. Screw holes 22 are provided for attaching the clamp 11 which covers the bending parts A of the ball tube 9. The circular concave parts 20 which are machined at the position separated by the distance (d) are provided in the inside of the holes 12 with a drill and the like, and the mutual interference with the bending parts A of the ball tube 9 is prevented. Therefore, the mutual interference of the ball tube 9 and the tube inserting holes 12 is prevented. Since any circular concave part is not formed at the center parts of the opening ends of the tube inserting holes 12, the longitudinal length L 1  of the groove 19 for an 0 ring can be shortened. Therefore the outside sizes of the piston 5 and the clamp 11 can be set small, and the compact and light configuration can be obtained.

Title: Refractive index distributed single lens
Inventor: TAKADA KATSUHIRO
IPC: G02B3/00
Filed: 1985-01-16
Abstract: PURPOSE:To obtain a lens which has aberrations improved and has a high NA and use it as an object lens of a video disc or the like by constituting the lens so that it has a specific refractive index distribution and has one spheri cal refracting surface at least and satisfies specific conditions. CONSTITUTION:This lens has a refractive index (n) given by an equation n<2>= n<2>0{1-(gr)<2>+h4(gr)<4>+h6 (gr)<6>} where n0 is the refractive index of the center and (r) is the distance from the optical axis in the diametric direction and has one spherical refracting surface at least and satisfies conditions of 1.54f<D and -4<(g-0.5)D. In said equation and formulas, (g) is the parameter indicating the degree of the refractive index gradient, and h4 and h6 are coefficients of terms of fourth and sixth orders of the refractive index distribution respectively, and D is the lens length, and (f) is the focal length of the lens. Since the refrac tive index distribution is symmetrical with respect to the optical axis and said conditions are satisfied, the distributed index lens is obtained which has various aberrations compensated well and has not only >=0.5 NA but also >=0.7 NA which is difficult normally with respect to design.

Title: Oil cooler
Inventor: KATAYAMA KAZUMI
IPC: F28D7/16
Filed: 1987-01-13
Abstract: PURPOSE:To hold the function of an accumulator by providing a film which can be stretched and contracted between a drum and a group of pipes to form a closed space with the drum and the film and providing means to supply and discharge pressurized fluid into and from the closed space. CONSTITUTION:Between a drum 11 and a group 12 of pipes a cylindrical film 22 is provided which can be stretched and contracted to form a closed space 23 with the outer face of the film 22 and the inner face of the drum 11. Because in a stationary state no pressurized gas is supplied into the closed space 23, the film 22 is in contact with the inner face of the drum 11. The cooling water enters from a cooling water inlet port 17 and passes through the group 12 of pipes and flows out from a cooling water outlet port 18. High temperature oil enters the drum 11 from an oil inlet port 19, and exchanges heat with the cooling water and flows out from an oil outlet port 20. When a main pump is out of order, an aixiliary pump is started automatically and at the same time a pressurized gas flows into the closed space 23 to contract the film 22 so that the oil between the drum 11 and the group 12 of pipes is discharged out of the system to prevent the drop in the oil pressure. When the pressure of the auxiliary pump goes over a specified value, the pressurized gas in the closed space 23 is discharged and the closed space 23 returns to the stationary state.

Filed: 1991-01-18
Abstract: PURPOSE:To prevent system changeover of a transmission line when a transmis sion line termination panel is mounted only to one system in transmission lines in duplicate and it is faulty and even when the panel is mounted to the other system in a fault state. CONSTITUTION:When only a transmission line termination panel 1 is mounted and alarm information is sent from a selection transmission circuit 22 to a system selection circuit 23, and when a transmission line termination panel 0 is mounted in a fault state, the transmission of mount information is delayed from a mount information transmission circuit 01 and sent to a selection transmission circuit 21 simultaneously as the alarm information. In this case, the selection transmission circuit 21 sends the alarm information to the system selection circuit 23 with priority and the system selection circuit 23 does not change the system.

Abstract: PURPOSE:To output a split output image to a recording paper of the same size, by fixing a selected state of the recording paper to a recording paper of the largest size, in case the number of recording lines of a recording image accumulating means has become larger than the recording paper of the largest size. CONSTITUTION:A CPU 40 accumulates temporarily a received data in a compressed data area of an image memory 47, and thereafter, transmers it by one line each to an encoding/decoding part 51 and decodes it to its original picture signal, and accumulates it successively in a recording data area of the image memory 47. Subsequently, in accordance with width information of a received image and the number of lines, a recording paper is selected. When a picture signal of one line has exceeded width of the largest recording paper, at that time point, the largest recording paper which has been set to a plotter is set to remain selected, and the selected state is not changed until all images are recorded.

Title: Method for switching channel during communication of mobile communication system and mobile terminal equipment
Inventor: KANAI TOSHIHITO
IPC: H04W36/08
Filed: 1988-01-11
Abstract: PURPOSE:To prevent the increase in the local control quantity by sending a signal including a flag representing the presence and absence of an idle channel by each radio base station, receiving it by a mobile terminal equipment, sending a switching request signal after movement between radio zones is detected and switching the connection to the base station of the mobile destination having an idle channel. CONSTITUTION:A base station 3 and a mobile station 30 are connected through outgoing and incoming channels in frequencies fd, fu and in case of transfer to a radio zone of the base station 2 having an idle channel, the output of the receiver 35 is f2, which is larger than f3. A control circuit 36 based on a flag 40 compares the reception level of the base station to recognize the movement of the station 2 to the zone and sends the switching request to the station 2 through the incoming channel. The base station 3 sends it to an exchange station 10. The exchange station 10 selects the idle channel of the station 2 and instructs the number to a mobile terminal 30 via the station 3. The mobile terminal equipment according to the instruction switches the channel to that of the station 2. Thus, the movement between radio zones is monitored by the terminal equipment and the communication channel switching controlled is decentralized, then the local concentration of the control variable is avoided.
