Abstract: PROBLEM TO BE SOLVED: To secure a large space necessary for mounting and release of a reaction tube without providing a large space inside a reaction chamber and prevent corrosion of components and damage of a reaction tube, by rotating an upper heater at an upper limit stop position and thus opening the upper side of the reaction tube. SOLUTION: By releasing a lock pin 18, an upper block 19 and a lower block 21 are caused to move upward and downward, respectively, in the interlocking manner. That is, with a mid block 20 fixed on a frame 6 as the center, a lower heater 7 and an upper heater 2 move downward and upward, respectively, that is, in the opposite directions, and then stop at a lower limit position and an upper limit position, respectively. In this state, a handle 17 is rotated in the direction of an arrow A around a fulcrum 19a of the upper block 19, thereby opening the upper heater 2 by a predetermined angle. Thus, since a large space can be secured on all the sides of a reaction tube 1, particularly, on the upper side thereof, the reaction tube 1 can be easily replaced.

Title: Soft magnetic film
Inventor: SHIMIZU OSAMU
IPC: G11B5/31
Filed: 1989-01-19
Abstract: PURPOSE:To obtain high saturation magnetic flux density by causing 12-20atomic %(at%) Si and not more than 8at% N and the remainder Fe to be main components. CONSTITUTION:Composition of a soft magnetic film is such that 12-20atomic%(at %) Si and not more than 8at% N and the remainder Fe are the main components. Occurrence of N not more than 8at% lowers the coercive force Hc without lowering the saturation magnetic flux density Bs and improves corrosion resistivity and achieves larger hardness. Occurrence of 12-20at% Si can lower the coercive force Hc without making the saturation magnetic flux density Bs lower than a predetermined value by adding a particular amount of N. Thus, high saturation magnetic flux density Bs (for example B25>14kKG) and low coercive force Hc (Hc<3Oe) can be obtained.

Title: Atomic oscillator
Inventor: CHIBA KAZUHARU
IPC: H01S1/00
Filed: 1988-01-18
Abstract: PURPOSE:To make it possible to perform lighting and maintenance of the lighting state at low exciting electric power, by separating a lighting starting electrode and the ground after the lighting of a light source lamp is started so as to suppress the spread of emitted light, and connecting the lighting starting electrode to the ground so as to light the lamp. CONSTITUTION:Light, which is emitted from a light source lamp 1, is detected with a photodetector 6. Its output is amplified in an amplifier 7 and added to a lighting control device 8. When the light is emitted from the light source lamp 1, the contact point of a switch 4 is 'opened' in the lighting control device 8. When the light is not emitted, the cycle of 'closing and opening' of the switch 4 is performed at least one time. Therefore, the spread of the emitted light with the lighting starting electrode 3 after the lighting is eliminated. The light can be emitted stably by the less amount of light. In this way, the lighting and the maintenance of the lighting can be performed with low exciting electric power.

Abstract: PURPOSE:To provide the tape running device which facilitates setting operation regarding tension control over a tape. CONSTITUTION:First tension T1, second tension T2, and section length L3 being parameter information regarding the tension control over the tape are inputted through an input means 7.

Abstract: PURPOSE:To correct the measured value more accurately by forming the central line of projected luminous flux at an approximately vertical pattern with respect to the surface of a sample cell on which the light is projected, detecting the intensity of the reflected light at the illuminated surface, and obtaining the intensity of the monitoring light. CONSTITUTION:A light axis L of a collimate lens 16 is not formed in a correct vertical pattern but in an approximately vertical pattern with respect to a light-projected surface 20a of a sample cell 20. Thus, reflected exciting light is condensed in the vicinity of an output slit 14 of a spectroscopic monochrometer 12 for the exciting light through the lens 16. Then, the reflected light is detected with a photodetector 24A which is provided at this light condensing position. The light undergoes amplification 32 and A/D conversion 36 and the signal is inputted into a divider 40 as a divisor for the output value of the A/D converter 36. In this constitution, the reflectivity of the light-projected surface 20a is constant and not related to the absorbance of a sample 22. Therefore, it is not necessary to change the constant of a constant multiplier 41 even if the sample 22 is an unknown sample. Furthermore, since the intensity of the received light at the light-projected surface 20a is not affected with bubbles generated in the cell 20, the output of a photodetector 30 can be corrected more accurately.

Abstract: PURPOSE:To ensure a steady operation although the load reaches nearly a state of short circuit, by detecting the current flowing through the semiconductor switching element and then adding the current to the error current when the output voltage lowers less than the set value. CONSTITUTION:The error signal produced by the difference between the output detection signal of the output current IO or the output voltage VO and the reference voltage of the reference power source 10 is produced by the error amplifier 9 and then integrated by the integrating capacitor 7.

Thus the output voltage is produced when the integral voltage exceeds the reference voltage and applied to the latch circuit 3 via the delay circuit 5 as well as to the latch circuit 2 to stop the supply of the driving signal. On the other hand, the current flowing through the switching transistor is detected by the DC current transformer 20. Then the detection current is charged to the capacitor 7 only when the switch 21 which is opened when the load reaches neary a state of short circuit.
