Title: Measuring device for height of measuring instrument
Inventor: NOMOTO TETSUSHI
IPC: G01C15/00
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To measure the height of a device easily even by one person by changing the direction of an optical axis so as to displace the intersection of the optical axis and the ground surface by a fixed distance for determining the height of a measuring instrument. SOLUTION: The light of a light source 21 in an optical system 20 is beamed by condenser lens 22, and reflected by a reflector 23 diagonally-mounted to an optical axis at a 45 deg. angle to flood downward from an opening 29 on the bottom of the device. The reflector 23 is supposed to a rotating shaft 24 rotatable around a beam reflecting point. When the reflector 23 is brought into contact with a contact surface 26, a beam optical axis flooded by adjusting the position of the optical system 20 is made to meet the reference axis of a measuring instrument. When an encoder 27 detecting a rotating angle is mounted on the rotating shaft 24, and the reflector 23 is rotated by an angle of θ, the beam direction is changed by 2θ.  When the measuring instrument is leveled in such a way and the center is determined, the beam reaches a light- receptive part through the opening of a target to send a light-receptive signal to a processing part. The strength of the light-receptive signal is maximized when the center is determined precisely, thus it is possible to conduct centripetal operation precisely.

Title: Control device for continuously variable transmission
Inventor: MINAGAWA YUSUKE
IPC: B60W10/06
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To suppress change in the behavior of a vehicle when the acceleration pedal is stamped or brakes are applied while the vehicle is running on a low-μ road surface. SOLUTION: When judgement is passed that the vehicle is running on a low-μ road surface, the maximum Cmax and minimum gear ratios Cmin in the D-range gear ratio region are restricted to the maximum Csmax and minimum gear ratios Csmin in Snow mode so that the extent of the shift region is narrowed, and no fuel cut for engine is performed to be executed when the degree of throttle opening is fully closed.  On a low-μ road surface, excessive action of engine brake originating from the gear ratio being controlled to a greater minimum gear ratio Csmin is avoided by generating an engine torque of a certain size in which the fuel cut is prohibited, and a braking effect due to an appropriate engine brake is obtained, and the drawing-in of engine torque at the time of the acceleration pedal of being stamped again can be avoided, so that the frequency of braking operation, etc., on low-μ road surface can be reduced and also a change in the engine torque be suppressed to lead to the suppression of the change in the behavior of vehicle.

Title: Spread spectrum communication method and communication equipment
Inventor: ISHII HIROTAKE
IPC: H04B1/707
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To obtain a correct signal not affected by a frequency deviation by accumulating at an accumulator although an error takes place when the frequency deviation is in existence in a local oscillator between a transmitter and a receiver and an output signal of the accumulator is subjected to a delay detection. SOLUTION: When a frequency deviation is in existence in a local oscillator between a transmitter and a receiver, since a sine wave whose frequency is Δf is multiplied with an input signal to multiplier circuits 31, 32, a received wave is inverted after 1/2Δf[S] period. Thus, a signal BQ' being the output of an accumulator 35 has a waveform as shown in figure B. When the signal BQ' is subjected to delay detection, an error is produced as shown in figure C in a signal DQ after detection. In this case, the signal DQ is accumulated by an accumulator 46 as shown in figure, the effect of the error is eliminated as shown in figure E in the output of a comparator 48. Thus, even when a frequency deviation is in existence in a local oscillator between a transmitter and a receiver, the deterioration in a code error rate is avoided and an information signal at a low speed is sent.

Title: Video signal processing circuit
Inventor: KUNIMORI YOSHIHIKO
IPC: H04N9/64
Filed: 1990-09-14
Abstract: PURPOSE:To prevent color drooping at a vertical edge by providing a switch circuit switching an input chroma signal and a signal resulting from processing the input chroma signal by a comb-line filter and using an output signal of an OR circuit so as to apply changeover control of the switch circuit. CONSTITUTION:A C non-correlation detection signal 1 is inputted to an OR circuit 180 to obtain OR with a Y non-correlation detection signal H'. When the detection of a vertical edge is not detected by the Y non-correlation detection signal H', An (n+2)th and (n+5)th line of an output signal J of the OR circuit 180 go to a Hi level as the vertical edge. Then only when an OR control signal J is at a Hi level, the switch 40 is switched via a switch 60 of a post- stage so that an input chroma signal C from an input terminal 200 is outputted to an output terminal 220. As a result, color drooping in the chroma signal outputted from the output terminal 220 is prevented. Thus, since either the C correlation signal or the Y correlation is in use, the color drooping is surely prevented.

Abstract: PURPOSE:To simplify constitution of a winding shaft and to perform reliable operation of a chuck mechanism and a clutch mechanism by a method wherein the chuck mechanism and the clutch mechanism are operated through a single compressed air feed device. CONSTITUTION:Compressed air fed to a hole 1a of a shaft body 1 passes a hole 1b and a groove 1d for feeding compressed air, by means of which a clutch mechanism is operated, to press a piston 5.

Title: Cooler of supercharger attached on engine
Inventor: SEKI KATSUHIKO
IPC: F02B39/00
Filed: 1988-09-28
Abstract: PURPOSE:To facilitate the circulation of a sufficient quantity of cooling water through a cooling water jacket of a supercharger during stoppage of engine operation by forming a circulating water circuit branched from an engine cooling water circuit with a water storage part partitioned into two chambers by a bulkhead. CONSTITUTION:During the operation of an engine 1, engine cooling water is partially branchedly circulated through a cooling water jacket 5a of a supercharger 5 to accomplish the cooling of the jacket 5a. Thus, in the process of the cooling water circulation, head pressure difference to water storage level is formed between the first and the second chamber 65, 66 in a water storage tank 6. Pressure balancing action due to the head pressure difference can therefore forcedly carry away the cooling water into a circulating water circuit during stoppage of the operation of the engine 1. Thus forced circulating action caused by the head pressure difference in the cooling water jacket 5a can synergisticly act on the substitutional circulating action caused by thermal siphon phenomenon occurring in the cooling water jacket 5a, and a sufficient quantity of the cooling water can thereby circulate certainly through the cooling water jacket 5a.
