Title: Device for adjusting pre-load of screw
Inventor: TAKASUGI HIDEO
IPC: F16B31/04
Filed: 1990-01-31
Abstract: PURPOSE:To easily manufacture a device and adjust its pre-load, and to reduce the cost by adjusting the pre-load through the relative rotation between first and second nuts, which have an internal bread to be engaged with the external thread of a screw shaft, an external thread on its outer periphery so as to engage with a housing, and are fixable to the housing by means of lock nuts. CONSTITUTION:A screw shaft 1 has an external thread 2. Bilaterally symmetric nuts 3 and 4 have respective internal threads 6 on their inner surfaces, and the respective outer peripheral surfaces composed of surfaces 7a, 7b and 7c on their outer peripheral surfaces. External threads 5 are formed on the outer peripheral surfaces 7b. On the other hand, an small size inner peripheral surface 12 to be filled to an outer peripheral surface 7c of the nuts 3 and 4, a middle size inner peripheral surfaces 13 having an internal thread 15 to be engaged with the external thread 8, and a large size inner peripheral surfaces 14 having an internal thread 17 to be engaged with lock nuts 16a and 16b are formed on the inner surface 11 of a housing 5. Consequently, adjustment of the pre-load can be accomplished through the rotation of the second nut 4 relative to the first nut 3, and these members can be locked by means of the lock nuts 16a and 16b. In this way, it is possible to easily manufacture a pre-loading device, to adjust its pre-load, and to reduce the cost.

Title: Mercury lamp with stabilizer built in
Inventor: SHIMIZU KENICHI
IPC: H01J61/96
Filed: 1978-02-27
Abstract: PURPOSE: To use a mercury lamp having a specific ratio of the consumed power of the lamp to that of a luminous tube during stable light-on, at a relatively low wattage, by coating the surface of an outer tube with a blue or greenish blue fluorescent substance of limited luminous peak wavelength.  
     CONSTITUTION: When the mercury lamp is stably lighted on, visible rays and ultraviolet rays produced by the luminous tube 2 and visible rays produced by a filament stabilizer 3 are radiated from the outer tube 1. The visible rays penetrates the outer tube 1. The ultraviolet rays collides against the fluorescent film 20 coated on the inside surface of the outer tube 1 so that the film 20 luminesces. The film 20 is made from the blue or greenish blue fluorescent substance, whose luminuous peak wavelength is 400 to 520 nm when the ratio WH/W of the lamp consumed power W to the luminous tube consumed power during the stable light-on is not more than 0.4. Thus, light of high color temperature is radiated out of the outer tube 1.

Title: Flaw detector
Inventor: MORI TADAO
IPC: G01N21/892
Filed: 1990-01-31
Abstract: PURPOSE:To detect even the elongated flaw coinciding with the running direction of a sheet to be inspected by providing a light projecting part scanning the sheet to be inspected at a predetermined angle with respect to the direction crossing the running direction of the sheet to be inspected at a right angle. CONSTITUTION:The laser beam 8 from a beam projection part 14 scans a sheet 1 to be inspected in an S-direction inclined by an angle theta (0 deg. < theta < 90 deg.) with respect to the direction crossing the running direction of the sheet 1 to be inspected at a right angle. When the sheet 1 to be inspected has no flaw, the scanning laser beam 8 transmits through the sheet 1 to be inspected as it is to straightly advance and is not incident to an optical rod 10. Therefore, no output appears in a light detection part 15. When the sheet 1 to be inspected has a long linear flaw 7 extending so as to coincide with the running direction of the sheet 1 to be inspected, the laser beam 8 is diffused by the flaw 7 to generate diffused beam 9 expanding into the plan crossing the longitudinal direction of the flaw 7 at a right angle. Therefore, a part of the diffused beam 9 is caught by the optical rod 10 and output appears in the light detection part 15. A data processing part 12 compares the output of the light detection part with a threshold value and, when the output is larger than the threshold value, the presence of the flaw 7 is judged.

Abstract: PROBLEM TO BE SOLVED: To maintain the stability of a fuel by a method wherein an oil pressure holding medium is supplied to a fuel system by adjusting the pressure and temperature thereof according to a pressure varying with the increase or decrease in the amount of a fuel oil to accomplish accurate atomization of the fuel oil with the pressure thereof held as specified in a fuel system. SOLUTION: A cooler 13 measures the temperature of air previously compressed by a compressor leaving a chamber 15 it enters after the compression and applies the resulting signal to a temperature adjusting valve 14 from a temperature transmitter 23 to adjust the temperature of the compressed air to about 100 deg.C so that the temperature almost equals that of the fuel oil. Then, the compressed air undergoes an adjustment of pressure with a pressure adjusting valve 16. In this case, the pressure of the fuel oil is measured in the back wash of a burner valve 8 to adjust the travel of the pressure adjusting valve 16 by a pressure transmitter 22 for generating the resulting signal. Hence, the pressure of the compressed air is adjusted to a proper value.  Thus, the compressed air adjusted in temperature and pressure according to the temperature and the pressure of the fuel oil is supplied to the fuel system.
