Title: Key operating device
Inventor: TAKAHASHI TOSHIHIKO
IPC: G11B15/02
Filed: 1987-05-23
Abstract: PURPOSE:To prevent the unexpected mis-operation of a key or disturbance by the operation of another person from being generated, by prohibiting an operating mode corresponding to a designated operating key by designating a prescribed operating key, and canceling the prohibition of a designation key only when the same personal identification number is inputted. CONSTITUTION:The operating keys 19a-19f to set the operating mode, and ten keys 19g are provided. Also, a means to store an arbitrary personal identification number set by the ten keys 19g, and the means to register the designation key on the operating keys 19a-19f are provided. And coincidence between a number numeral inputted from the ten keys 19g and the personal identification number is decided by a decision means, and the operating mode by the designation key is prohibited until the decision of the coincidence is obtained. Therefore, it is possible to prohibit the shift of the operating mode to an undesired specific operating mode by designating the mode, and also, the operating modes except a designated mode are valid, therefore, it is enough to prohibit a minimum necessary number of operating modes. In such a way, the unexpected mis- operation or the disturbance can be prevented from being generated.

Title: Measuring device for retardation time
Inventor: KURUTO GIGAA
IPC: G01S17/14
Filed: 1983-07-12
Abstract: Apparatus for measuring the time delay between pulse signals, particularly in conjunction with electro-optical range finders. A coarse measurement counter counts the output of a reference oscillator, while a fine measurement interpolator determines the residual time at the start and finish of a measuring interval. Both residual times are successively determined by the same fine measurement interpolator. A delay circuit only supplies the pulse transmitter with the trigger signal when the interpolation for the start signal in the interpolator is ended. An adjustable series of test pulses is produces by a clock generator, in order to form the average value from such a series of measurements in a logic circuit. Preferably, the clock generator is synchronized with the reference oscillator, which ensures the formation of a mean value with a narrow range of errors.

Abstract: PURPOSE:To enter the cooling of an X-ray tube corresponding to the actual temp. thereof, by mounting a means entering the cooling of the X-ray tube when the temp. of a case of cooling medium exceeds a predetermined value and determining the cooling time of the X-ray tube on the basis of scanning results and the cooling characteristic of the X-ray tube at other time. CONSTITUTION:An operation part 19 calculates the present temp. of an X-ray rube from the temp. measured value from a converter 18 at the time when a power source is turned ON, on-line scanning results and the cooling characteristic of the X-ray tube and determines the possibility of the next scheduled scanning or the next scheduled cooling time. When the power source is turned ON, the operation part 19 calculates the temp. of a case from the temp. signal of the converter 18 to judge whether said temp. exceeds a predetermined value and, when the temp. of the case exceeds said value, the X-ray tube is subjected to cooling. Therefore, scanning becomes an interrupted state. When the temp. of the case is the predetermined value or less, the possibility of scanning or a cooling time is determined on the basis of scanning results (temp. rises at every scanning) and the cooling characteristic of the X-ray tube.

Title: Automatic fluid direction controller
Inventor: SUGAWARA NORIO
IPC: F24F1/00
Filed: 1977-10-24
Abstract: PURPOSE:To control the direction of a conditioned air stream automatically by changing the angle of a blade according to the temperature of the flued. CONSTITUTION:A control part 11 is composed of a controlling main body 11a to be expanded and contracted by thermal detection, and a transmitting part 11b to convert these expansion and contraction of the main body 11a into the rotation of a horizontal blade 10. For heating, the controlling main body 11a is expanded to turn a horizontal blade 9 to direct the downstream side downward through a transmitting part 11b. Among three jet streams A--C divided at a blow off part 7, the stream A is forced to turn to the side of a sticking wall 13 by the horizontal blade 9 and flows along the sticking wall 13 by Coanda effect. At this stage, the stream B is turned downward by the stream C, and made to join the stream A by the attraction of the stream A for flowing along the sticking wall 13. Consequently, all jet streams can be controlled by controlling a small jet stream A. On the other  hand, for cooling, the horizontal blade 9 is turned upward, and jet streams A--C  are spouted horizontally without being influenced by the sticking wall 13.
