Patent JP-S61184480-A (JP)
Title: Proximity alarm apparatus
Inventor: SAKASHITA HIROHIKO
IPC: G01S15/10
Filed: 1985-02-12
Abstract: PURPOSE:To emit an alarm when a person is present immediately in front of a television receiver, by arranging an ultrasonic sensor to the front surface of the television receiver. CONSTITUTION:A first piezoelectric element 3 for transmitting an ultrasonic wave and a second piezoelectric element 4 for receiving a reflected wave are arranged to the front surface of the cabinet of a television receiver. The torn burst signal driving the first piezoelectric element 3 is generated from a tone burst generator 2 and the detection signal detected by the second piezoelectric element 4 is amplified by an amplifier 5 so as to have sufficient amplitude to be applied to a comparator 6. The comparator 6 compares said detection signal with the period of the pulse '0' of a timing generation circuit 1 and, if there is detection voltage in this period, a confirmation signal is sent to an alarm 7. By this method, when a person is present in the vicinity of the front surface of a television, an alarm is issued to urge a person to step back.

Title: Refractive index distribution type plastic optical transmission body
Inventor: TOYODA NOBUHIKO
IPC: G02B3/00
Filed: 1991-01-28
Abstract: PURPOSE:To make the distribution of the transmitted light quantity more uniform within the optical transmission body. CONSTITUTION:This refractive index distribution type optical transmission body has a circular section of a radius ro and the distribution of the light quantity within this optical transmission body is uniformized by continuously changing the concn. distribution of a light absorptive material from the center toward the outer peripheral part. For example, >=2 kinds of mixtures which are polymerizable materials consisting of polymers and monomers liquid at ordinary temp. and vary in refractive index are made into >=2 layers of laminated structural bodies by using a concentrical composite spinning nozzle, etc., and are molded to a prescribed shape. The molding is polymerized and cured while or after a smooth refractive index distribution is provided thereon by the interdiffusion transfer of the monomers in the polymerizable mixtures between the respective layers. Dyes, such as azo dyes and anthraquinone dyes, are exemplified as the light absorptive material. The adjustment of the refractive index of the polymerizable mixtures varying in the refractive index is executed by specifying the polymers and changing the kinds, compounding ratios, etc., of the monomers and light absorptive materials to be added to these polymers.

After the substrate 8 to be coated is held by the chuck, the substrate is lowered by which the substrate 8 is immersed into the photoreceptor coating liquid 9 in a coating tank 10. A fan motor 11 is run during the descending operation or after the end of the descending and the gas is released or inhaled from the surface of a vent filter 2 via a vent tube. As a result, the concn. of the photosensitive coating liquid solvent vapor near the surface of the coating liquid 9 is made controllable. The solvent vapor concn. is set at the concn. to be determined. A solenoid valve 12 operates to release the accumulated pressure of the gas in the vent filter to the outdoor air right after the release of the gas from the surface of the vent filter 2 or the insulation of the gas ends.

Abstract: PURPOSE:To enable photographing operations to match an examinee's natural breathing interval by measuring the time of action to respond to voice instructions such as breathe, etc., of the examinee before performing X-ray photographing operations, and performing a process for setting the timing that matches this measured value in actual photographing. CONSTITUTION:The time of action of an examinee to respond to voice instructions is measure before photographing operations are carried out; i.e., when instructions to initiate measurement are inputted from an input device 1, a voice that says 'Breathe and stop' is issued from a voice synthesizer 4 via a measurement controller 2. The operator observes the breathing of the examinee and sends a signal to finish operations from the device 1 when making sure that the examinee has finished breathing, thereby storing the breathing time of the examinee in a storage device 7 as the time required for the examinee to respond to the instruction: 'Breathe and stop'. The time stored is utilized in future photographing work. That is, after the time stored has elapsed, instructions to start photographing operations are given to a CT image computing device 3, a scanner control device 6 and an X-ray controller 5.
