Title: Automatic transmission for vehicle
Inventor: TANAKA KOICHI
IPC: F16H3/44
Filed: 1994-02-09
Abstract: PURPOSE:To miniaturize an automatic transmission for vehicle and reduce its weight by shortening the length in the axial direction between an engine and a counter gear of the automatic transmission. CONSTITUTION:A friction engaging section 408 of a fourth brake B214 and a piston pressing mechanism section 412 are separated each other and arranged on both sides in the axial direction of a counter (driven) gear 231a so that a piston 410 of the fourth brake B214 is across the counter gear. The piston 410 is provided with a knotched section in a part which corresponds to a mesh section of the counter gear in the peripheral direction relative to the axis of the piston 410. On the other hand, a bent section is formed at an end of a contact separator plate 404a, and the bent section is engaged with the knotched section in the peripheral direction of the piston 410. As a result, rotation around the axis is prevented. Also, interference between the piston 410 and the counter gear is prevented because rotation around the axis of the piston 410 is prevented due to this composition, although the piston 410 is across the counter gear.

Title: Electric resistance type flaw detector
Inventor: ENDOU TAKASHI
IPC: G01N27/20
Filed: 1979-02-13
Abstract: PURPOSE: To improve the flaw detecting sensitivity of an electric resistance type flaw detector by burying a plurality of probes in an elastic magnet to form the electric resistance type flaw detector which can thus move the probes in three dimensions and can closely make contact with the complicated surface to be detected.  
     CONSTITUTION: Four probes 2 are formed by conductive material in spherical or conical shape as small electrodes, and buried, for example, at predetermined interval and position in an elastic magnet such as rubber magnet 3 so that the ends are projected from the surface of the magnet 3. Further, a push plate 4 made of elastic synthetic rubber or the like is adhered onto the back surface of the magnet 3. This flaw detector body 1 is urged from its top with a stationary push plate 7 through a spring 8 onto the surface to be detected by a handle 9. Since the probes 2 are buried in the magnet 3, they may move in three dimensional directions to make close contact with the surface to be detected in complicated shape to improve its flaw detecting sensitivity.

Abstract: PROBLEM TO BE SOLVED: To discriminate whether a business office machine is accurately operated or not. SOLUTION: User setting of the business office machine like a copying machine is analyzed to discriminate that there is a problem in the business office machine. If user setting is frequently so set that it is deviated from default setting by a prescribed extent, default setting is improper and it is necessary to perform the processing like the change of parameters of the business office machine. After it is found that default setting is a problem, the business office machine communicates with a diagnosing service center by connectionless mode communication (562 to 566 and 570 to 580). If the problem of the business office machine cannot be resolved remotely, the diagnosing service center requests a service call (568 and 582).

Title: Driving method for liquid crystal panel
Inventor: IRIE HIROYUKI
IPC: H04N3/12
Filed: 1979-02-14
Abstract: PURPOSE: To decrease the decay time and thus improve the deterioration of the picture quality caused by the response property of the liquid crystal panel, by applying the output signal of the horizontal oscillation circuit to the common transparent electrode.  
     CONSTITUTION: The driving system comprises DC voltage application terminal 10, horizontal oscillation circuit 11, capacitor 12, AND gate 13 and others. In such constitution, gate 13 is controlled to open for the flyback time of the vertical synchronous signal sent from synchronous isolator circuit 7, and the signal synchronized with the horizontal synchronous signal of circuit 11 is supplied to gate 13. Then the output of gate 13 is applied to terminal 11 periodically, and thus the AC signal is applied to terminal 11 in piling onto the DC voltage. In such way, the conventional circuit can be applied directly, and furthermore the response of the liquid crystal is increased by shortening the decay time. As a result, the after-image on the liquid crystal panel can be decreased to enhance the picture quality.

Abstract: PURPOSE:To prevent increase in resistance of a diffused layer and to prevent punch through of wiring metal in the diffused layer at a contact part even if the source/drain diffused layers become shallow due to the shrinkage of a device, by providing a region other than a part neighboring a shallow low-concentration layer in a shallow high-concentration layer so that said region is deeper and has higher concentration. CONSTITUTION:N-type impurity ions are implanted in the entire body of a source/drain forming region, and an insulating film 26 is formed. A wide side wall 26a is formed on the side wall of a gate electrode 24. N-type impurity ions are implanted 27 in a region, which is not covered with the side wall, in order to form a deep high concentration layer. Etching is performed again, and a wall 26b, which is narrower than the wall 26a is completed. At this time, an exposed substrate undergoes heat treatment, and an oxide film 28 is formed. The P ions 25 and N-type impurities 27 in the substrate are diffused and activated. A shallow N<-> layer 29 is formed in adjacent to the gate electrode 24. An N<+> layer 30 is formed at a part separated from the electrode 24. Ions are implanted 31 again in order to form a deep N-type high- concentration layer in a region, which is not covered with 26b. By heat treatment, an N<+> layer 32 is formed in a region neighboring 26b in the source/drain forming region deeper that the layer 29.

Abstract: PURPOSE:To improve the dimensional accuracy of the final molded goods of powder molding press by controlling the speed between both upper and lower punches from the start of pressurization to just before a pressurization completion position and mechanically positioning the pressurization completion position by stoppers. CONSTITUTION:The relative moving speeds of the upper punch 4 and the lower punches 11, 12, 13 are so controlled that the speed ratios to compress the powders in the parts corresponding to respective step parts attain the compressive size ratios between the respective step parts of the final molded goods in the pressurization control of the stepped molded goods with the powder molding press. The pressurizing force acting on the punches driven by auxiliary driving means exclusive of the pressurizing ram of the press body among both the upper and lower punches in the pressurization end position is mechanically supported by stoppers 33, 34 separately from the auxiliary driving means 31, 32, by which the punches are positioned. As a result, the outputs of the auxiliary driving means for driving the punches to pressurize the step parts are diminished, by which the size is reduced, the generation of crack is obviated and the dimensional accuracy of the final products is improved.

Filed: 1987-01-29
Abstract: PURPOSE:To improve the real time property of digital signal transmission by temporarily storing digital signals obtained by voice encoding circuits in memory circuits and multiplexing them after division and transposition in order circuits. CONSTITUTION:A transmission equipment consists of plural channels ch1 and ch2 of systems, which have voice encoding circuits 1a and 1b which subject voice inputs to A/D conversion at every sampling period to compress bands, memory circuits 3a and 3b where digital signals outputted from these voice encoding circuits are temporarily stored, and order circuits 4a and 4b which successively read out temporarily stored digital signals and input them to not only divide them into an optional number but also arrange them on the time base, and a multiplexing circuit 5 which multiplexes output signals from order circuits of respective channels and transmits them to a transmission line. Since digital signals which are divided into N-number of signals and are arranged on the time base at every sampling period are multiplexed and transmitted, the time from reception of the signal of the channel ch1, to reception of the signal of the channel ch2 is shortened to 1/N of the conventional time to improve the real time property.
