Title: Sele-tuning receiver and decoder for frequency-shift keying rf data transfer
Inventor: URURITSUHI KAIZAA
IPC: H04L27/12
Filed: 1994-12-05
Abstract: PURPOSE: To provide a frequency shift modulated receiver/decoder at high data rate. CONSTITUTION: An RF step having a resonance circuit 10 is turned at a 1st frequency among four possible transmission frequencies and in accordance with such sequential frequency calls, this type of frequency is received. A threshold value 18 and counter circuits 12 and 16 respectively detect the frequency shift change of transfer frequency, and by respectively counting such a received frequency through a prescribed sequence, the resonance circuit is tuned at subsequent unknown frequencies again. A means 24 is provided for latching the bit signal of a frequency shift data as its output in the same format as a received frequency shift RF format.  The receiver and decoder are especially effective for minimized transponder operation in which it alternates between receiving and transmitting modes, and the power is supplied by capacitively stored charges in response to the continuous transfer of 1st frequency for a fixed period.
Patent JP-H04151113-A (JP)
Title: Optical connector
Inventor: IWANO SHINICHI
IPC: G02B6/36
Filed: 1990-11-08
Abstract: PURPOSE:To prevent an optical plug and a plug adapter from disconnecting from each other even when an optical cord is loaded with a large tensile force by providing a projection part for disengagement which abuts on an abutting part to deform an elastic arm elastically. CONSTITUTION:When the optical plug 14 is inserted into the plug adapter 11, the engagement projection 18 of the optical plug 14 abuts on the engaging claw 25 of the projecting elastic arm 24 of the claw holder 23 of the plug adapter 11 and the elastic arm 24 united with the claw holder 23 deforms elastically to move the engaging claw 23 onto the projection 18 for engagement, so that the engaging surface 26 of the projection 18 for engagement and the engaging surface of the engaging claw 25 engage each other. When the optical cord 17 on the side of the optical plug 14 is drawn, its force is transmitted to the engaging claw 25 through the projection 18 for engagement, but the root part of the elastic arm 24 for the claw holder 23 of the plug adapter 11 deviates from the operation point, so bending moment which puts the tip side closer to the optical plug side 14 around the root part operates on the elastic arm 24. Consequently, the engagement state is surely held.

Title: Liquid level gage
Inventor: NISHIMURA KAORU
IPC: G01F23/28
Filed: 1987-11-30
Abstract: PURPOSE:To detect the surface of liquid with a simple constitution, by utilizing the changing phenomenon of the amount of reflected light in an optical fiber when the optical fiber, which is wound in a spiral pattern, is put into the liquid. CONSTITUTION:A piece of optical fiber 3 is wound around an pipe 1 in a spiral pattern. When a liquid surface E is located at the wound part, introduced light K is emitted into the liquid, and the amount of the leaking light becomes large. The light does not reach a light receiving part. The fact that the wound part is positioned at the liquid surface is detected. Therefore, the constitution is made simple, and the alignment of a light axis is not required. Thus, a liquid level gage characterized by low noises can be implemented.

Title: Emergency braking device for preventing slip of automobile
Inventor: TOMINAGA MOTONORI
IPC: B60T8/34
Filed: 1994-12-06
Abstract: PURPOSE: To safely and positively stop an automobile even on a road surface having a very low coefficient of friction, on which the car cannot be effectively braked even by what is called ABS system. CONSTITUTION: When an electronic control device 3 judges that the slipped state of automobile wheels detected by a detecting means such as a jaw rate sensor 1 or a steering angle sensor 2 is untolerably large, the control device 3 starts an emergency braking device (a second braking means 6). That is, the control device 3 operates a hydraulic changeover valve 4 to switchingly supply the pressurized oil from a master cylinder or other oil-pressure generating devices to a hydraulic cylinder 6b. Thus, a friction material 6a is movedly operated, and the friction material 6a is directly engaged with the road surface to restrain the car on the road surface to positively stop the car at this position.  At the same time, since a warning means 5 such as a klaxon, is energized, by the control device 3, to give an alarm that the surrounding persons, vehicles, etc., should not be close to the car, accidents due to contact can also be prevented.

Filed: 1990-11-07
Abstract: PURPOSE:To increase the light emitting and absorbing efficiencies of the title element by using such a quantum well structure that the interface between a well and barrier layers is constituted of an inclined layer having a continuously varying forbidden band width. CONSTITUTION:A barrier layer 51 is made of InP and a well layer 52 is composed of an InGaAs layer 53 and inclined layer 54.

Title: Method and apparatus for measuring distribution of particle size
Inventor: MAIKERU ENU TOREINAA
IPC: G01N15/02
Filed: 1990-11-07
Abstract: PURPOSE: To make it possible to measure the particle size distribution by directing one beam of light to a scattering medium and generating first and second signals whose magnitudes represent key parameters, converting it into logarithmic scale, and decomvoluting it. CONSTITUTION: The one beam from a laser diode light source 12 is introduced into particulate substance 20 in a sample cell 18 via an optical coupler 14 and optical cable 16. Light scattered by the particles is generated. The scattered beam is back scattered into the cable 16, and reversely guided to a photodiode detector 11 via the coupler 14. The output signal from the detector 22 is amplified and filtered via a DC blocking filter 24, amplifier 26, and filter 28, and sent to an A-D converter 30 and central processor 32. Further, the equal scale of the power spectrum is converted into logarithmic scale by a vector signal processor 34, and sent to the processor 32. Thereafter, the converted signal is unfolded mutually, the particle size distribution in the scattered medium is judged and decomvoluted. Thus, the particle size distribution can be measured.

Title: Exhaust gas recirculating valve
Inventor: SEKIGUCHI YUKICHI
IPC: F16K31/122
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To suppress generation of noise without having to reduce the moving speed of a valve element during a closing stroke. SOLUTION: Upper and lower throttle parts 32 and 33 are protruded from a first cylinder chamber 18, to reciprocate a valve stem 7 coupled to a valve element 6 to open and close the valve port 4 of an EGR valve 1 and a first piston 21, and a second cylinder chamber 24 and a second piston 28. The upper throttle part 32 is formed in a manner to be inserted in the opening part 15a of a first port 15, to feed air to the upper side of the first piston 21 of the first cylinder chamber 18, and the lower throttle part 33 is formed in a manner to be inserted in the opening part 31a of the communication passage 29 of the second piston 28.  Thus, the throttle part reduces the speed of a piston, by throttling a flow of fluid in the vicinity of the terminal point of a closing stroke by the valve spring of the piston and prevents the generation of strike noise as a result of the piston colliding with a cylinder chamber. Since the stroke speed of the piston is set to a high value, the generation of black smoke during pedaling of an accelerator is prevented from occurring through prevention of the increase of a closing stroke.
