Title: Bearing device for straight type 6 cylinders internal combustion engine
Inventor: TANAKA YASUHISA
IPC: F16C9/02
Filed: 1979-11-30
Abstract: PURPOSE: To prevent an internal one side touch of each bearing of a straight type 6 cylinders internal combustion engine and reduce its friction loss, by varying the oil clearance of each slide bearing supporting a crankshaft, depending upon the value of impact load imposed on each slide bearing.  
     CONSTITUTION: Among slide bearings 4aW4g supporting a crankshaft 2, the clearances of the third bearing 4c and the fifth bearing 4e are set larger than the corresponding value to impace load, and the clearance of the fourth bearing 4d is set smaller than the corresponding value to impact load. Furthermore, among the clearances which are set on each bearing 4aW4g corresponding to impact load, the fourth is largest, and the clearances of bearings are set so as to meet those orders of value such as the fourth > the first, the seventh > the third, the fifth > the second, the sixth. Thereby, any internal one side touch of each bearing is prevented, and the friction loss is reduced.

Abstract: PURPOSE: To enhance the quality of a displayed picture, by separating the received echo signals through a transducer into high frequency signals and low frequency signals, compressing either by different compression circuits, and then forming a signal for display by addition of the compressed signals. CONSTITUTION: Output signals of a transducer (converter) 12, which scans a prescribed fan-shaped area by transmitting ultrasonic signals into the body of a patient, is received by a receiver 19 through a switching measure 18, and the received echo signal is then transferred to LPF 26 and HPF 27 through an A/D converter 24. The low space frequency signal and high space frequency signal from either filter 26 and 27 enter the different compression circuits 28 and 29 respectively. Where the low space frequency signal is compressed with high compression ratio and the high space frequency signal with lower compression ratio. Then an addition circuit 31 adds either output after compression. Thus obtained addition output enters a digital scanning and converting circuit 32 to pretreat the data for display purpose, and then is displayed on a display unit 37.

Title: Optical coupler
Inventor: NAKAGAWA EIICHI
IPC: G02B6/42
Filed: 1987-06-23
Abstract: PURPOSE: To stabilize optical coupling by fastening and fixing an optical fiber to a holder.  
     CONSTITUTION: The optical fiber 5 (sphere-pointed fiber) the front end of which is worked to a spherical shape is fixed to a sleeve 7 by means of solder 6. The sleeve 7 and the holder 3 are fixed by welding while the fiber is held Optically coupled to a light emitting semiconductor element LD 1 on a carrier 2 and further the sleeve 7 and the holder 3 are fixed by welding. The sphere- pointed fiber 5 is fastened and fixed directly to the holder 3 by a retaining plate 9 made of metal and screws 10. The solder 6 is generally liable to be deformed when a temp. fluctuation arises, but the retaining plate 9 and the screws 10 are not easily deformed and since the holder 3 and the carrier 2 are fixed by welding, the change in the relative positions by the deformation is obviated. The positional relation between the LD 1 and the sphere-pointed fiber 5 is thereby stabilized.

Title: Digital-analog converter
Inventor: YOSHIHARA MINORU
IPC: H03M1/66
Filed: 1982-09-09
Abstract: PURPOSE:To improve the accuracy, by DA-converting sequentially a digital data at each unit weighting from the start of the weighting operation to its end, so as to suppress the increase in the changing step width of an analog output because of the increase in the weighting amount. CONSTITUTION:In doubling the weighting to a command pulse control section 10 and an FB(feedback) pulse control section 11 (N=2), the count of counters 12, 13 is progressed respectively by 2N, i.e., 4-step at each application of a positive command signal COMP or a positive FB pulse FBP, and the count is operated by 2-step only when the command input or the FB input is zero. Since an output data of a full adder 14 is obtained at the count of the counters 12, 13, the digital data to a DA converting section 15 is revised at each T/N period, where T is the revised period of the command input and/or the FB input and N is the multiple of weighting, and the changing step width of an analog signal is not increased even if the weighting multiple N is increased.

Title: Satellite channel back-up system
Inventor: UCHIDA MAYUMI
IPC: H04B7/15
Filed: 1988-06-23
Abstract: PURPOSE:To automatically back up a satellite channel by means of the channel itself so that the reliability of the channel can be improved by previously storing two frequencies in a base band processor and using the frequencies by switching when a fault occurs. CONSTITUTION:When a transponder TRSP repeating the output frequency becomes detective while satellite communication is normally carried on, a transponder fault notice is sent from the transponder TRSP to s satellite network control processor SNCP. The processor SNCP outputs a output frequency changing notice to a satellite access controller SAC. As a result, the controller SAC sends information to a base band processor BBP with a new output frequency thereafter. The new output frequency is one of the two frequencies stored beforehand in the E<2>PROM of the base band processor BBP and the processor BBP sets the output frequency by managing the two frequencies with a timer.

Title: Airframe
Inventor: KUROSAWA HIROMITSU
IPC: F42B15/01
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To keep an air frame stable against disturbance by fully opening a shutter right after a launch in order to reduce front wing area and to locate an aerodynamic center of gravity at a position to the rear of a center of gravity of the airframe. SOLUTION: A shutter 12 is kept opened right after a launch. Because combustion of a propulsion part 6 starts along with the launch of an airframe and mass of a rear part of the airframe decreases along with the combustion of the propulsion part 6, a center of gravity of the airframe starts moving to a front side. Propulsion part combustion time is measured by a signal processing device and at a stage after an elapse of a predetermined time a closing travel of the shutter 12 is transmitted to a shutter drive part 13. The shutter drive part 13 is operated according to the closing travel of the shutter and the shutter 12 is closed by a specified travel and area of a front wing increases due to slit closure so that the aerodynamic center of gravity starts moving to the front side.

IPC: H04L69/40
Filed: 1988-06-24
Abstract: PURPOSE:To execute a line cut-off process in a short period of time by causing a host computer to transmit a selecting sequence to a terminal when a no- communication state occurs during data communication and, when no answer is made from the terminal continuously for a specific number of times, executing the line cut-off process. CONSTITUTION:A no-communication state monitoring means 11-1 actuates a non-communicating state terminal monitoring means 11-2 upon detecting a no-communication state of a prescribed period while a terminal 3 makes data communication. Then the means 11-1 transmits a selecting sequence to the terminal 3 and monitors the answer of the terminal 3. When the terminal 3 makes no answer to the selecting sequence within a prescribed period, the means 11-1 decides whether or not the sequence is repeatedly transmitted by a specific number (n) of times. When the number of transmitting times reaches the specific number (n) of times, the means 11-1 instructs a line cut-off means 12 to execute a line cut-off process. Upon receiving the instruction, the means 12 disconnects the host-side communication line 4 used for the data communication with the terminal 3 by the prescribed processing.
