Title: Vehicle position detector
Inventor: KATSUNO TOSHIYASU
IPC: G08G1/16
Filed: 1990-10-31
Abstract: PURPOSE:To enable detection of a distance to a target and a bearing thereof without depending on a phase difference detection system by using a brightness modulation attributed to an equal interval barcode of a target photographed with a single CCD line sensor. CONSTITUTION:A body part 10 has a lens 14 and a CCD line sensor 16 and is provided at a specified position on a road to take a target 18 on a pole having an equal interval bar code at a view angle alpha. A distance to the target and a bearing thereof are calculated using a brightness modulation attributed to the equal interval bar code of the target 18 taken with the single CCD line sensor 16. In other words, elements composing the CCD line sensor 16 are divided into several blocks with a plurality of the elements as one block to calculated a brightness modulation frequency at each block. The brightness modulation frequency depends on the equal interval bar code the target 18 has. But the frequency profile changes according to a relative position between the CCD line sensor 16 and the target 18 thereby enabling the calculation of a relative distance to the target 18 and a relative bearing thereof.

Title: Flash x-ray tube with rotary anode
Inventor: ISOBE HIROSHI
IPC: H01J35/10
Filed: 1989-11-15
Abstract: PURPOSE:To reduce the melting of an anode and obtain a long life by providing a bar-shaped cathode oppositely to a rotatable disk-shaped target formed with a projection having a triangular cross section. CONSTITUTION:Electrons field-emitted from the tip section 8a of a cathode 8 collide against a focal point orbit connecting tops of triangular projections 7a formed on the outer periphery of a rotatable target 7. When the rotating speed of the target 7 is properly set in response to the preset focal point orbit diameter and the photographing interval, the electron collision point for each photographing can be displaced to the nearby position not affected by heat. When the electron collision point for each photographing is displaced, the local temperature rise of the target 7 is suppressed, the melting of the target 7 is reduced, and the repeated photographing at short time intervals can be performed for a long period.

Title: Blood pressure measuring apparatus
Inventor: HANADA YASUSHI
IPC: A61B5/022
Filed: 1992-11-04
Abstract: PURPOSE:To enable the measurement of a blood pressure over a long period of time without applying any burden on a blood pressure measuring part by pressurizing a pressure cuff and bag at one stroke to a reference cuff and bag pressure in the measurement of the blood pressure following the second operation using the maximum blood pressure obtained in the first blood pressure measurement as such. CONSTITUTION:A pressure cuff and bag 1 mounted on a blood pressure measuring part is pressurized with the operation of a pressurizer 10 and the current cuff and bag pressure thereof 1 is detected with a pressure sensor 12. A pulse wave which is obtained with the vibration of the wall of a blood vessel during the pressurization of the pressure cuff and bag 1 is detected from an output of the pressure sensor 12 through a BPF13 to derive the maximum blood pressure (or an average blood pressure) with a control part 17 from the results of the detection. In this case, at the control section 17, firstly, the quality of the pulse wave and the cuff and bag pressure at the maximum blood pressure to be obtained by the first blood pressure measurement are stored separately and in the blood pressure measurement following the second measurement, the pressure cuff and bag is pressurized up to the cuff and bag pressure stored. The quality of the pulse wave obtained during the pressurization to the cuff and bag pressure is compared with the quality of the average blood pressure during the first measurement thereby monitoring changes in the quality of the pulse wave.

Title: Optical fiber coupler
Inventor: SASAKI KAZUMASA
IPC: G02B6/28
Filed: 1989-11-13
Abstract: PURPOSE:To efficiently couple plural optical signals by arranging a flat coupling window at the projecting side of a curvature part by bending an optical fiber at a specific angle, and connecting closely a second optical fiber whose tip is cut at a constant angle to the coupling window. CONSTITUTION:The flat coupling window 13 is provided at the side plane of a main line optical fiber 11 by bending, and the optical signal of a branch 14 is injected to the main line optical fiber 11. At this time, the field distribution of injection light can be connected so as to be sufficiently superimposed on the waveguide of the main line optical fiber 11, and an injection light mode can be efficiently coupled with the waveguide mode of the main line optical fiber. At such a case, loss can be reduced since disturbance other than curvature is scarcely received with the main line optical fiber, and an injected mode can receive appropriate mode disturbance due to axial deviation, etc., at the coupling window, and mode distribution is diffused, and coupling to plural modes can be performed. Thereby, it is possible to prevent the signal S3 of the main line 11 weakened and to couple the optical signal S4 of the branch 14 with certain practical efficiency.

Abstract: PURPOSE:To avoid a fault due to insertion/withdrawal of a live line and a job of live line insertion/withdrawal by revising a check circuit under the control of an external control signal in the case of checking occurrence of a fault in the device or the like. CONSTITUTION:In the case of checking a loopback operation at the side of terminals (terminals SIN, ROUT, SS and RR) of an in-station device, only an external control signal LB is set active. Then a relay RL2 is operated and a speech signal inputted from a terminal SIN is outputted to the terminal ROUT through a loopback circuit 17 connecting to the terminal ROUT. Since a signal from the in-band signal device 101 is not outputted, malfunction due to the presence of the device is prevented. In the case of checking the operation of the in-band signal device 101, no external control signal is inputted and both the LB signal and a NOR signal are cleared.

Abstract: PURPOSE:To produce the subject compound useful as an intermediate for pharmaceuticals and agricultural chemicals in high purity and yield by isomerizing 1,2,3,4-tetrahydroquinoline in the presence of a noble metal catalyst. CONSTITUTION:The objective 2,3-cyclohexenopyridine is produced by isomerizing 1,2,3,4-tetrahydroquinoline in nitrogen gas atmosphere in the presence of a noble metal catalyst such as palladium-carbon at 200-250 deg.C for 1-7hr.
