Title: Fullerene-binding water-soluble polymer photosensitizer for photodynamic therapy
Inventor: IKADA YOSHITO
IPC: A61K9/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To obtain a photosensitizer for the photodynamic therapy by chemically modifying fullerene with a water-soluble polymer. SOLUTION: Fullerene is made soluble in water and given the cancer tissue- targeting properties after its intravenous administration. The difference in disappearance pattern of accumulated fullerenes from the tissues is cleverly utilized to increase the concentration difference between the normal tissues and the cancer tissues and the photodynamic therapy effect that only cancer tissues can be broken by radiation with light is recognized. Thus, the fullerene-water- soluble polymer binder can be expected to be used as a photosensitizer for the photodynamic therapy.

Title: Timepiece with battery life annunciating function
Inventor: WATANABE KENICHI
IPC: G04C10/04
Filed: 1981-06-02
Abstract: PURPOSE:To prevent the consumption of an almost discharged  battery from  being accelerated in a timepiece which uses a battery for an alarm circuit in addition to a battery for a timer circuit, by annunciating the consumption of one  battery by using another battery.

Abstract: PURPOSE: To obtain an evaluation apparatus which eliminates the distortion of an X-ray diffraction pattern and which eliminates an individual difference with reference to the evaluation of the diffraction pattern by a method wherein the face of a crystal body and the face of a photographic plate are arranged in parallel and a moving measuring stage is scanned while their parallel relationship is being kept. CONSTITUTION: X-rays from an X-ray source 10 irradiate a crystal body 20, as an object to be measured, through respective slits 11, 12, a diffraction beam 7 which has been diffracted by the crystal body 20 is shone at a photographic plate 21 through a slit 13, and a diffraction pattern is obtained. Then, the photographic plate 21 is arranged in parallel with the crystal body, and the wave passage of the diffraction beam 7 is set to be always a constant distance even when a moving measuring stage 15 is moved. The more the number of slits such as the slits 11, 12 and the like which are to be installed before the crystal body 20 is, the beam can be narrowed down, but it is sufficient to install at least one slit before the crystal body 20.  Thereby, since the distortion of the diffraction pattern by a defect detection apparatus by means of Lang's method can be eliminated, an individual difference with reference to the evaluation of the diffraction pattern can be eliminated.

Polystyrene or a styrene-alkyl acrylate copolymer is, e.g. used as the 1st bonding resin. The resultant kneaded material is further kneaded under melting with a 2nd bonding resin and a substance required to exist on the surfaces of toner particles so as to fulfil the function (e.g. an electrostatic charge controlling agent) and then pulverization and classification are carried out. The 2nd bonding resin may be the same resin as the 1st bonding resin but it is necessary that the wt. average mol.wt. of the 2nd bonding resin is lower than that of the 1st bonding resin.

Abstract: PURPOSE:To obtain a high-quality image pickup tube which enables a high resolution, a reduced after-image, a homogeneous picture quality, and a live image pickup with a high S/N  ratio by using a high-melting-point metal such as tantalum or molybdenum for the control electrode and the like of a photoconductive pickup tube for a TV camera. CONSTITUTION:In a bipolar-operating-layer-flow-type electron gun of a photoconductive pickup  tube in which an impregnated radiator is used as a cathode 1 and a signal-accumulation target is subjected to a low-speed scanning by forming an electron beam 4, a perforated plate 3c  having a beam regulating opening 5 used for the formation of the beam 4, and a control electrode 30 used for supporting the plate 3c are prepared from the same simple high-melting-point material such as tantalum or molybdenum. As a result, any separation or the like of an electrode material, which conventionally was caused due to the overheat developed either during  the operation of an image pickup tube, or during the activation of a cathode and the degassing  of an electrode which were carried out in the exhausting process of the tube, is removed.  Consequently, a high-quality image pickup tube which enables a live image pickup and can be  applied to a TV system which essentially requires a picture with a higher quality than the conventional standard, such as a TV system having a horizontal-scanning-line number of 1125,  a field frequency of 60Hz and a video-frequency range of 60MHz, can be developed.

Filed: 1980-06-24
Abstract: PURPOSE:To increase the accuracy of processing and to reduce the deterioration of Q, by processing the resonator of cilindrical type torsional oscillation system constituting a mechanical metallic filter through the use of n-sets of laser light equally shared on a circular circumference to a center axis. CONSTITUTION:The resonance frequency of a resonator 4 of a cylindrical type torsional oscillation system is measured at a resonance frequency measuring device 2, it is compared with an objective frequency with a controller 3 to calculate the frequency deviation to be processed. Succeedingly, the device 3 obtains the laser emitting position on the end of the resonator 4 in response to the amount of processing and radial alignment is made by a linear driving device 6. Furthermore, the resonator 4 is turned around the center axis through a rotating driving unit 5 and laser processing is made by radiating laser from a laser device 1 at the same time. The frequency of the resonator 4 is adjusted by repeating said steps. Thus, the frequency deviation is reduced to 1/n through the use of n-sets of laser, and processing accuracy is increased by the radiated position to be accessed to the center axis. Further, the processed holes are uniformly distributed to the center axis to decrease the deterioration of Q.

Title: Cathode-ray tube and manufacture thereof
Inventor: YAMASHITA NAOTAKA
IPC: H01J31/20
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To effectively prevent deterioration of reflectance of a panel surface. SOLUTION: While the reflectance of an adhesive layer (UV cured resin layer 12a) being made to be approximately the same as that of the adhesion face (the back face of a plastic film substrate 14) in a functional film 16 side, the reflectance and viscosity of the adhesive layer 12a are so adjusted and adhesion of the functional film 16 is so carried out as to make it possible to bury cracks 14a formed in the adhesion face in the adhesive layer 12a. Consequently, void formation attributed to cracks 14a can be prevented. Since the adhesive layer 12a and the plastic film substrate 14a are previously adjusted as to have approximately the same reflectance, the reflectance is not fluctuated due to the cracks 14a buried in the adhesive layer 12a and to this extent, the existence of cracks can be neglected.  As a result, property deterioration of the reflection preventing film 18 and image defect formation can be prevented.
