Abstract: PURPOSE:To prevent the deterioration of a semiconductor laser due to mechanical stress by providing a protruded metallic electrode which forms a cavity over a stripe shaped region. CONSTITUTION:On a substrate 101, are formed the first clad layer 102, an active layer 103, and the second clad layer 104.

Then, the pot 23 is decompressed with a vacuum pump 29, hydrogen and tritium in Na are transferred to gas and discharged through a degassing pipe 25, and the vapor and mist of Na are removed in traps 26, 27. Thereafter, the exhaust gas is mixed with air from a blower 33 and reacted with O2 in a catalytic oxidizing device 35. The resulting steam-contg. gas is disharged through a gas- water separator 42 to the atmosphere, after most of steam is separated as water from it by a cooler 37.

Title: Nitrogen-doped silicon single crystal wafer having low defect density and it production
Inventor: IIDA MAKOTO
IPC: C30B15/04
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To produce a nitrogen-doped silicon single crystal wafer in high productivity by excluding dislocation cluster while remaining excess interstitial silicon atoms over the whole surface or a part of crystal. SOLUTION: A silicon single crystal is grown by Czochralski process by pulling up the crystal while doping the crystal with nitrogen under a condition to hold excess interstitial silicon atoms over the whole area of a part of the crystal. The distribution of defect is shifted to the high-speed side of the pull-up speed and the generation of dislocation cluster ordinarily occuring at an I-rich region is prevented by this process. Accordingly, the controlling tolerance is widened and the control becomes easy when the crystal is pulled up in a region having I-rich region over the whole surface or a part of the crystal and a silicon single crystal having extremely low defect density and free from dislocation cluster even in an I-rich region can be produced in high productivity.  Preferably, the amount of doped nitrogen is >=1×10<14> atoms/cm<3> and the oxygen concentration in the crystal is <=1×10<18> atoms/cm<3> .

Title: Film feed control device of camera
Inventor: IGUCHI SUSUMU
IPC: G03B17/42
Filed: 1980-12-08
Abstract: PURPOSE:To prevent a photographed part of a film from being exposed, by providing an element for detecting that a back cover of a camera is opened, and an element for detecting that a part to be photographed of a film is still left, and winding a film into a magazine by a detection output of both these elements. CONSTITUTION:A counter switch SW1 is off when a display value of a counter is >1, that is to say, at least one film to be photographed is left. Now, when the counter switch SW1 is off, the back cover of a camera is opened, and when a back cover switch SW2 is turned on, both inputs of a NAND gate are H and its output becomes L, therefore, a transistor TR1 is turned on and a motor M is rotated forward. As a result, a film is drawn in as far as its terminal of a magazine and is stored, therefore, even if a back cover of a camera has been opened suddenly in case of a camera of stand-by winding system, no photographed part is exposed.

Title: Control method for x-ray ct device and x-ray ct device
Inventor: YOSHITOME EIJI
IPC: A61B6/03
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To collect data only between the prescribed phases of the periodical movement of a scanning object by measuring data under the revolution of an X-ray tube with a revolution time not an integer time as long as the period of the movement of the object, and measuring data for a view corresponding to a rotational angle over a shorter measurement time. SOLUTION: A central processing device 3 detects a period (h) and a phase from the R-wave of an electrocardiogram signal and retrieves a table stored in a memory device for taking out a delay time (d) corresponding to the period (h), a measurement time (e), a revolution time (K) and a measurement frequency (n), when only data in the diastolic phase of a heart is collected with an X-ray CT device 100. Then, when an operator enters a scanning command from an input device 2, an X-ray tube 11 giving one revolution in the time (k) is continuously rotated to start the irradiation of an X-ray on timing elapsed by the delay time (d) from the R-wave of the electrocardiogram signal, thereby measuring data over the measurement time (e). Thereafter, an image reconstituting operation is made on the basis of collected data to form a tomography.

Filed: 1981-10-29
Abstract: PURPOSE:To facilitate the assembly of a first and a second driven gears on a main shaft, by fitting a positioning collar in the bosses of the gears to restrict the eccentricity between the gears. CONSTITUTION:A positioning collar 31 is fitted in the bosses 31a, 32a of the first and the second gears 31, 32. A spring 121 for shifting the phases of the teeth of the gears 31, 32 is provided between them. Since the gears 31, 32 are previously aligned to each other by the collar 31 against the biasing force of the spring 121, the gears are easily fitted on the main shaft 14 of a transmission when a clutch is mounted on the main shaft. The assembly of the clutch on the transmission is thus facilitated. In idling, the elastic force of the spring 121 causes the teeth of the gears 31, 32 to pinch those of a driving gear 2 so that the driving and the driven gears 2, 3 are engaged with each other without backlash.
