Title: Structure of rotary anode x-ray bulb
Inventor: ARAI KATSUTOSHI
IPC: H01J35/10
Filed: 1980-08-13
Abstract: PURPOSE:To enable the usage even under the intense heat load condition, by placing a tubular member between the inner-circumference of a rotor fixed with an anode target and the outer-circumference of the rotary shaft then connecting the anode side to the rotary shaft thereby reducing the heat to be transmitted to the bearing. CONSTITUTION:A tubular flange tube 11 is placed between the outer-circumference of the rotary shaft 7 and the inner-circumference of a rotor 3A where one end is fixed to a target 2 while the outer-circumference of the other end is fixed to the rotor 3B of a drive motor, while the anode target side is connected with the rotary shaft 7 through a bolt 12 and the counter anode target side is connected with a rotor 3A through such as electron beam welding. Then for example, a bolt insertion hole 13 is blocked by such as a screw to prevent the radiation heat while the depth of the flange tube 11 is made uneven in axial direction and hole, slit, etc. are made in the outer-circumference. Consequently the length of the heat path to the rotary shaft, bearing, etc. is increased while the cross-section is reduced to increase the heat resistance thereby the temperature of the bearing can be reduced.

Title: Optical multiplex transmission system
Inventor: KOKUBU TOSHINAO
IPC: H04B10/54
Filed: 1989-04-28
Abstract: PURPOSE:To improve the economy and reliability by combining the intensity and wavelength of optical signals to apply multiplex transmission of two signals. CONSTITUTION:A wavelength variable semiconductor laser 20 has an intensity control input terminal 21 and a wavelength control input terminal 22 and the intensity of an output light is controlled in response to an injection current I1 from the intensity control input terminal 21 and the wavelength of the output light is controlled to lambda1 (I2=0) or lambda2 (I2not equal to 0) in response to the injection current I2 from the wavelength control input terminal 22. Thus, the wavelength variable semiconductor laser 20 radiates a multiplexed optical signal whose intensity varies with a high speed pulse signal and whose wavelength varies with a low speed pulse signal. That is, one signal to be multiplexed is sent while being subjected to the intensity change of the optical signal of each wavelength, and the other signal is sent while being subjected to the wavelength change of the optical signal of each wavelength. Thus, the transmission system with high economy and reliability is built up.

Title: Battery voltage detection circuit
Inventor: YAMADA MASANORI
IPC: H02J9/06
Filed: 1990-04-26
Abstract: PURPOSE:To prevent the error detection taking the battery circuit cutoff for battery over-discharge by a method wherein the title circuit discriminates between natural discharge and removal of the battery by the speed of the voltage change, in the battery voltage detection circuit in the power supply circuit including a DC-DC converter which converts battery output voltage and supplies it to load. CONSTITUTION:Circuit constant is set in advance so that the divided voltage by resistors 13 and 14 may be higher than the divided voltages by resistors 15 and 16 during usual battery backup operation. When the battery 2 is cut off, the divided voltage outputs of the resistors 13 and 14 get on zero levels in order, but the charge voltage of a capacitor 12 does not get to the zero level instantaneously. Therefore, the output of a comparator 17 is on a high level during that time, and a transistor 18 is turned on first. Since the base of a transistor 6 is clamped on a low level, even if the output of the voltage detection circuit 4 changes meanwhile, the transistor 6 is never turned on. Therefore, an alarm indication is not issued in the case of the cutoff of the battery.

Title: Coloring method for glass
Inventor: WATANABE YUICHI
IPC: C03C4/02
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To color glass efficiently and uniformly up to its inside by using a method which makes use of degenerative two-photon absorption for coloring glass. SOLUTION: To photochemically color the glass, the degenerative two-photon absorption is used. Namely, when the glass is photochemically colored, the coloring is performed uniformly in the depth direction of light incidence by making use of photochemical reaction wherein the degenerative two-photon absorption is induced. Here, when the glass contains cadmium or lead as its element, the photochemical reaction can easily be induced and the glass which is colored by the photochemical reaction can be put back into a colorless state through a heat treatment. As a light source used for the photochemical coloration, laser light of 400 to 700 nm in wavelength is suitably used and the output of the light source is preferably 10 to 5000 MW/cm<2> .  This method is able to color the glass along its depth, so when it is used for memory, not only recording on the surface, but also recording in the depth direction become possible.
