Title: Temperature sensitive switch
Inventor: KALAPODIS JAMES B
IPC: H01M50/583
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a temperature sensitive switch assembly body externally attachable to a battery to protect a battery from a thermal runaway. SOLUTION: This temperature sensitive switch assembly body A contains an electrical insulating spacer 12 sandwiched between a pair of flat metal plates 14, 16 and a switch blade member 10 of shape memory metal. The spacer 12 frames a cavity 24 between the pair of flat metal plates 14, 16, and the switch blade member has a blade part 30 projecting in the cavity. The switch blade member has a fixing part engaged with the one metal plate, and the switch blade part is normally engaged with the other metal plate by receiving a bending stress and enclosingly sets a current passage between the pair of metal plates. The switch blade 30 is deformed and moved so as to break off from a state of engagement with the other metal plate to break the current passage.

Title: Production of carbon fiber-reinforced carbonaceous composite
Inventor: OKUYAMA KOHEI
IPC: C04B35/52
Filed: 1987-12-29
Abstract: PURPOSE:To obtain the title composite with the short carbon fiber homogeneously dispersed, outstanding in sliding characteristics and strength, by impregnating carbon fiber assembly prepared by a specific process with a resin or pitch followed by calcination and, if needed, graphitization. CONSTITUTION:A mold with the bottom provided with many solvent discharge holes is fed with carbon fiber pref. 0.3-100mm long and a solvent (e.g. water, acetone) in combination or separately. Thence, said short carbon fiber is homogeneously dispersed in the solvent followed by removing the whole solvent through said holes to produce a preform. The carbon fiber assembly consisting of this preform is then impregnated with a resin (e.g. phenolic resin, furan resin) or pitch followed by calcination and furthermore, if needed, graphitization, thus obtaining the title carbon fiber-reinforced carbonaceous composite.

Abstract: PURPOSE:To allow the suppression of unwanted wave, generated from a delay line at a timing different front a target signal, at the unwanted wave suppression ratio of the delay line or above by driving an unwanted wave eliminating circuit while controlling the timing CONSTITUTION:When a voltage comparing circuit 17 decides that the absolute value of input signal is higher than a threshold value, a detection timing signal is delivered from the circuit 17 to a gate delay circuit 19. The circuit 19 creates a gate against field through at a point delayed by a time up to the detection timing signal with reference to a transmission gate received through a gate signal input terminal 25 and a gate input circuit 10. Furthermore, a gate against triple transit echo is created at a point corresponding to the sum of times T and t2. The gate width of the signal is then extended to cover the pulse width of unwanted wave at a gate width control circuit 20 and delivered to a switch drive circuit 21. The gate signal is converted through the-circuit 21 into a driving level of a switch 13 and applied thereto as a driving voltage.

Title: Electronic optical tube
Inventor: MORITA HIROBUMI
IPC: H01J37/141
Filed: 1988-12-29
Abstract: PURPOSE:To obtain a forming beam having a uniform current density distribution at a high resolution by arranging all electronic lenses on a sample side beyond forming diaphragms. CONSTITUTION:An electron beam 2 generated in an electron beam source 1 is directly radiated in a forming diaphragm 3. The electron beam 2 after passing through the forming diaphragm 3 passes through another forming diaphragm 3', where an incident position to the forming diaphragm 3' can be varied by a forming deflector 5 so that the size of the passing beam can be varied. The formed beam after passing through the forming diaphragm 3' is reducedly projected on the surface of a sample 4 through lenses L1, L3, L4. Although an image with half-shadows generated in the forming diaphragms is projected on the surface of the sample 4 because no lens is arranged between the two forming diaphragms 3, 3', the halfshadows are reduced by the lenses L1, L3, L4 so as to become enough small on the surface of the sample 4, thus occurring no problem in practice. Therefore, it is possible to obtain the forming beam having a uniform current density distribution at a high resolution.

IPC: H04N9/04
Filed: 1994-12-19
Abstract: PURPOSE: To control the brightness of an object itself through correct detection of the brightness and to keep the brightness of the object itself constant by discriminating the object based on a hue. CONSTITUTION: A system control circuit 31 uses an average value calculation processing circuit 31A to divide a signal level detection result S3 from an integration circuit 32C with an area detection result SAR1 to detect an average level S4 of a digital luminance signal as to a hue designated by a cameraman or the like. In the television camera, the object is discriminated based on a hue to detect the lightness of the object. Thus, in this television camera, when an object is arranged to part of an image, or an object is arranged at a corner of an image or the like, the brightness of the object itself is correctly detected and the aperture is controlled based on the detected brightness of the object to keep the brightness of the object itself constant.

Filed: 1993-12-27
Abstract: PURPOSE:To reduce power consumption and unevenness in luminance by converting light radiated from a small light emitting body of a light emitting element at a wide solid angle into light almost parallel and having narrow directivity by a condenser lens. CONSTITUTION:Light radiated from the light emitting element 12 at a wide solid angle is converted into light almost parallel and having narrow directivity by the condenser lens 15 and made incident from the counter electrode side of a liquid crystal panel 16. An observer contacts his (or her) eye closely to an eyepiece cover 92 and observes a display picture on the panel 16. Namely the position of an observer's pupil is almost fixed. When it is supposed that all picture elements on the panel 16 allow light to go straight on, the lens 15 controls light radiated from the element 12 and made incident upon an effective area of the lens 15 so as to make all of it incident upon the observer's pupil after transmitting it through an enlarging lens 105. Thus the observer can observe the small display picture on the panel 16 as an enlarged image. Namely the observer can observe an enlarged virtual image.
