Abstract: PROBLEM TO BE SOLVED: To obtain InGaAs quantum dots emitting at specified wavelength band by, unitarily determining specified multiples of the repetition no. of times while in the change from a two-dimensional growth to a three-dimensional growth in certain growth conditions. SOLUTION: A step of alternately feeding III and V org. metal materials to a semiconductor base having a first lattice const. is repeated to form a III-V semiconductor thin film having a second lattice const. different from the first one. The crystal growth temp. and the repetition no. of times N of alternately feeding the materials are, as parameters, varied by the divisions of less than the growth temp. of 30 deg.C, in order that the repetition no. of times N is changed to exceed M×No where No is the repetition no. of times of feeding the materials when the growth mode of the film changes from a two-dimensional growth L1 to a three-dimensional growth L2 at each crystal growth temp. at the condition M>1.

Title: Radiation detector
Inventor: TAMURA MASAKAZU
IPC: G01T1/185
Filed: 1987-09-04
Abstract: PURPOSE:To stabilize detection sensitivity by using gaseousHe and gaseous Xe as an ionizing gas and setting the mixing ratio thereof at Xe/(He+ Xe)=0.01-0.1. CONSTITUTION:A gaseous mixture 14 composed of the gaseous He and the gaseous Xe is used as the ionizing gas filled between a cathode electrode 1 and anode electrode 2 of a radiation detector. The compsn. of the gas 14 is particularly preferably set within the range of Xe/(He+Xe)=0.01-0.1. The fluctuation in the value W of the ionizing gas is extremely little even if the gaseous Xe proportional to the quantity of fission products intrudes into the ionizing gas and the effective compsn. of the ionizing gas changes and, therefore, the fluctuation in the detector sensitivity is similarly decreased and the detection sensitivity is improved.

IPC: H04N5/937
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To reproduce and display dynamic and still image files through linking by storing a still image in the high resolution mode at an optional point of time while a dynamic image in a usual resolution mode is being recorded and recording a switching history so as to reference the history later. SOLUTION: When recording command on an entry menu of a monitor 8 is sent to a video processing section 9, motion image data are read in a RAM 3 by a camera section 10 and stored in a moving image file of an auxiliary recording device 5. When a still image recording button is depressed on the way, still image data are read and stored in a still image file with a switching history and dynamic image data recording is restarted again. In the case of reproduction, at first the switching history is read and whether an image is a still image or a dynamic image is discriminated, and in the case of the dynamic image, the image is read from the dynamic image file and displayed.  In the case of the still image, a still image button is displayed on the entry menu for a prescribed time by a timer 4 and when the button is depressed, the dynamic image reproduction processing is stopped and the still image reproduction processing is started. Thus, at which point of time the high resolution image is recorded is easily recognized and the excellent operability is obtained.

Abstract: PURPOSE: To prevent a resonance circuit from being deteriorated by releasing the resonance circuit by a fuse member in response to a 2nd energy level signal of which energy level is higher than a 1st energy level signal and electrically connecting circuit parts through the fuse. CONSTITUTION: Spiral conductors 22, 24 are mutually connected by a fuse wave FW to constitute a resonance circuit. A fuse member 37 has low electric resistance and is comparatively short. Thereby the thermal energy of the circuit is not almost or illegally influenced. The preferable whole electric resistance of the member 37 is about 0.1Ω. The preferable length range of the member 37 is 0.05mm to 0.15mm. The member 37 is fused by the 2nd energy level higher than the 1st energy level capable of driving the resonance circuit. Consequently the deterioration of the resonance circuit can be prevented.

IPC: B60G17/015
Filed: 1991-09-02
Abstract: PURPOSE:To improve the comfort in sitting in a car cabin by studying the condition of the current road surface whether it is easy to generate flapping, allowing changing-over easily into the flapping suppressive control in case the road surface condition is easy to generate flapping, and permitting changing- over into such control not to be actuated in case not easy to generate. CONSTITUTION:The actual resonance level of a car is compared with the allowable resonance level, and if the actual is over the allowable, the suspension of the car is turned harder. This car is equipped with a means C for setting of the studying level which is lower than the allowable resonance level, a means D to calculate the frequence of the actual resonance level exceeding the studying level, and a means F to correct the allowable level in accordance with the frequence. Accordingly the frequence increases if flapping is likely to be generated, when the allowable level will be corrected lower, and it is easy to change over into flapping control.

Abstract: PURPOSE:To minimize the lowering of the temperature of coffee drip to be extracted without damaging the operability of the taking in and out of a coffee drip receiver by equipping the title device with a movable body to isolate the coffee drip to reach the inside of the coffee drip receiver from the flowing out port of a dripper from outside air, etc. CONSTITUTION:When the coffee drip is to be extracted, under a state in which a pot 7 is arranged under a dripper 23, first, an operating protruding part 37 is gripped, and a movable body 25 is turned counterclockwise. Thereupon, a hook piece 32 comes off from a plane 30b of a guide 30, slides down along a slant face 30a, and hooks in the bottom surface of a fixed body 24. Consequently, the movable body 25 is moved down, and the lower edge opening of a cylindrical part 36 of the body 25 surrounds an entrance 8 of the pot 7 and is supported on the upper surface. Thus, the cylindrical part 36 of this movable body 25 isolates a flowing out port 34 of the dripper 23 and the entrance 8 of the pot 7 opposite to the flowing out port 34 at its lower side from the outside air in the outside of the cylindrical body 36. Consequently, even when the coffee drip is to be extracted under conditions in which a room temperature is low, it can be prevented that the coffee drip is cooled by the outside air.
