Filed: 1984-07-03
Abstract: PURPOSE:To record and reproduce exactly and automatically an object part of a broadcast by transmitting a control signal for indicating the start and end of a program by using a sub-voice band of sound multiplex broadcasting in a television braodcast, and starting and ending the recording. CONSTITUTION:Immediately before the next program 16 is started, a program start control signal 15 is transmitted and received, and this signal is amplified, detected and demodulated by a receiving circuit 5, outputted to an output terminal 7 of a control signal and inputted to an input terminal 9 of a control signal of a megnetic recording and reproducing device 10. This signal is applied to a controlling circuit 12, by which a magnetic tape is driven. When an end control signal 17 is transmitted and received as soon as the program 16 is ended, it is operated so that the mechanism 13 is switched to an REC-PAUSE state from an REC-PLAY state. A sub-voice of a sound multiplex broadcast is transmitted and received by a method which is entirely different from a usual voice, therefore, when the control signal of the start or the end of the program is transmitted by utilizing the sub-voice band, no influence is exerted at all on a video signal and a usual voice.

Title: High-temperature heat exchanger
Inventor: IMANISHI KATSUOMI
IPC: F28F9/24
Filed: 1993-06-10
Abstract: PURPOSE:To obtain a high-temperature heat exchanger in which the upper face of a tube sheet is kept from reaching a high temperature and the pressure boundary of shell-side fluid is kept in a sound condition. CONSTITUTION:A high-temperature shell-side fluid A flowing into a first stage baffle through a high-temperature fluid inlet pipe 24 tends to flow toward a tube sheet 27 at the same time the fluid A turns back toward a second stage baffle. However, as two or more radiation panels 26 are installed in two or more stages at intervals in a space inside a heat exchanger, which is below the level of the high-temperature fluid inlet pipe 24 and above the tube sheet 27 that supports heat transfer tubes 28, and cuts of the radiation panels 26 are arranged alternately, the shell-side fluid A that flows toward the tube sheet 27 flows zigzag along the radiation panels 26, preventing the upper face of the tube sheet 27 from being heated to a high-temperature. When a heat transfer tube breaks, a tube-side fluid B flows out on to the baffle plates 25, falls on the uppermost baffle plate 25, then flows zigzag along the baffle plates 25 and gathers in heat protecting sections 32, so the tube-side fluid B does not flows out toward piping side through the high-temperature fluid inlet pipe 24. At that time, as most of the tube-side fluid B remains unevaporated although a portion of it comes in contact with interior structures and evaporates, the pressure boundary of the shell- side fluid A is kept in sound condition.

Title: Calibrating method for leakage inspecting apparatus
Inventor: FURUSE AKIO
IPC: G01M3/26
Filed: 1991-06-11
Abstract: PURPOSE:To obtain a leakage inspecting apparatus which can perform calibration without replacing calibrating devices even if the inner volume of a container under inspection is large or small. CONSTITUTION:The equal air pressure is applied to a container under inspection 16 whose inner volume is given as the known number and a reference tank 17 for a specified time. The amount of the air which is leaking from the container under inspection 16 is directly read based on the value of the pressure difference generated between the container and the tank. In the leakage inspecting apparatus of this type, a minute leak valve 37 whose flow rate is known is mounted on a pipe which gives air pressure on the container under inspection 16. The air is made to leak through the minute leak valve 37 for a specified time. It can be regarded that the leakage is equivalent to change of the inner volume of the container under inspection 16 by the known amount. The equivalent inner volume of the container under inspection 16 is obtained based on the change in equivalent inner volume, and calibration is performed.

Abstract: PURPOSE:To display an image pickup pattern corresponding to a picture border of a photo camera onto an electronic view finder. CONSTITUTION:A video camera section and a photo camera section are arranged integrally in a cabinet. A zoom lens is employed for an image pickup lens 2 of the video camera and a fixed focus lens is adopted for an image pickup lens 3 of a photo camera. A variable resistor 44 is arranged to the image pickup lens 2 to apply a detection signal SD in response to the zoom magnification to a controller 27. The controller 27 controls a zoom driver 41 of the image pickup lens 2. When a mode changeover switch 43 connecting to the controller 27 is set to the photo camera mode, the controller 27 controls the zoom driver 41 to make the picture angle of the image pickup pattern coincident with the picture angle of the photo camera, When the picture angle of the photo camera is set, the detection signal SD reaches a prescribed value. Since the image pickup pattern corresponding to the picture border of the photo camera is displayed on the electronic view finder, the user suitably implements the shutter of the photo camera.
