Title: Electromagnetic focussing type cathode-ray tube
Inventor: SAKURAI SOUICHI
IPC: H01J29/64
Filed: 1979-06-15
Abstract: PURPOSE:To make round the shape of beam spots on the fluorescent screen by providing a means which does not make round the electron beam spots which are incident on the electromagnetic focussing site at the front stage of the electromagnetic focussing site. CONSTITUTION:The first grid electrode 23 has the non-disk type elliptical electron beams passing hole 23a and its long axis which is slightly inclined from the Y axis. When the electron beam radiated from the cathode 2 pass through this first grid electrode, direction (y) receives weaker focussing and the crossover of the electron beams moves on the fluorescent screen side. This moves the image point in the direction of (y) on the fluorescent screen side on it. By focussing the image point on the fluorescent screen in both the directions (x) and (y), the shape of the beam spots is made round.

Title: Analyzer of language meaning
Inventor: MURAKI KAZUSHI
IPC: G06K9/72
Filed: 1983-04-28
Abstract: PURPOSE:To analyze the sentence of all fields with high efficiency and at a high speed by using pragmatic table information to verify the structure of an input sentence in terms of a meaning and producing correct meaning relation from said verification. CONSTITUTION:An input sentence given from an input line 01 is read into a sentence structure analyzing mechanism 1, and an internal structure rule is used to estimate successively the modifying relations of words, phrases and clauses. If this modifying relation comes to its end, another modifying relation is estimated. When the overall modifying relation is fixed, this relation is delivered to an output line 10. This output is supplied to a pragmatic table retrieving mechanism 2 to stop the processing of the mechanism 1. Then NULL is received from the mechanism 2 via a communication line 21, and the mechanism 1 uses another structure rule to have new estimation. Then the next analysis is carried out when the mechanism 1 receives the information excepting the NULL. The information on the correct meaning relation is applied to a pragmatic table memory 3 from a spare line 23. Thus the sentences of all fields are analyzed with high efficiency and at a high speed.

Title: Optical fiber diffusion delay equalizer
Inventor: IMOTO NOBUYUKI
IPC: H04B10/2525
Filed: 1979-06-16
Abstract: PURPOSE:To make the device simple and small in size and decrease the insertion loss of the equalizer by connecting the guides of the specified length longitudinally in correspondence to the wavelength lambdai of light waves, providing the specific reflecting films of the central wavelength lambdai at their connection faces, and fetching the light reflected by each reflecting film to the outside from the same optical path. CONSTITUTION:Light from an optical fiber 1 is passed through a polarizing and separating prism 11 such as Rochon prism and a 1/4 wavelength plate 12 and is thereby made into the circularly polarized wave which is then led to the diffusion delay portion consisting of wavelength selective reflecting films 13-1-13-N and optical guides 14-1-14-(N-1). The length of the delay optical guide for the wavelength lambdai is made li=LS(lambdai-lambdai+1)c/2n and the resolving power of the reflecting films having a center at lambda1 is made about (lambdai-lambdai+1)/2. Here, L, is the length of the optical guides, S is their wavelength diffusion, (n) is refractive index and (c) is the velocity of light. The light reflected by each reflecting film passes the route in the direction opposite from that at the time of incidence and is led to the outside by way of the optical guide 5. This diffusion delay equalizer is simple, small in size and has less losses.

Title: Semiconductor image pick-up device
Inventor: KONDO RYUJI
IPC: H04N5/335
Filed: 1985-04-11
Abstract: PURPOSE:To form an F.T type image sensor, which has a large aperture rate and can obtain excellent images, by forming recess parts in a blooming preventing well surface between neighboring picture elements, thereby suppressing the cross talk of the signal electric charge generated by the projection of light. CONSTITUTION:An F.T type sensor is obtained by the following processes. For example, phosphorus is doped in the surface of a semiconductor substrate having a conducting type, e.g., a P-type silicon crystal substrate 4 having the impurity concentration of about 5X10<14>atoms/cm<3> by an ion implanting method. Thus, a potential well 5, which is different from the substrate 4 and has the N-type low impurity concentration (e.g., doping amount of about 1.5X10<12>/cm<3>), is formed. Thereafter, dry etching of the upper part of the well 5 is performed with the upper part of the well 5 being masked so as to provide specified inter val. Thus recess parts 6a are formed in the surface of the well 5. It is effective when the depth (d) of the recess part 6a is about 2-6mum. The impurity concen tration and the depth of the well are selected so that only the wells, which are light receiving parts, become depletion layers 10 when a reverse bias voltage is applied between the wells and the substrate.

Title: Hot water supplyer
Inventor: FUJIWARA KATSUHIRO
IPC: F24H1/10
Filed: 1991-01-31
Abstract: PURPOSE:To prevent low temperature corrosion and obtain a sufficient amount of ordinary temperature water. CONSTITUTION:A relief line 5, which can be pass a sufficient amount of water, is installed in parallel to a heat exchanger 1. A three way valve 6, which switches a water flow line to the heat exchanger 1 over a water flow line to the relief line 5 is installed to a water intake line 2 connected with the heat exchanger 1. When it is desired to obtain ordinary temperature water from a faucet 13, the side of the heat exchanger 1 of three way valve 6 is closed while the side of the relief line 5 is opened. The water from the water intake line 2 does not flow past the heat exchanger 1, but supplies water from the relief line 5. Since water does not flow past the heat exchanger 1, no condensation water is generated, which makes it possible to protect the heat exchanger from low temperature corrosion. Furthermore, the ordinary temperature water can be supplied from the faucet 13, flowing in the relief line 5, there is no need for another water piping and water faucet separately from the hot water heater piping.
