Title: Partial memory single article acquisition method, semiconductor memory, memory module and compute system using the same
Inventor: FUKUDA HIROSHI
IPC: G11C29/04
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To make the areas other than the specified area of an external address usable by switching connection between the external address and an internal address of a partial memory with a partial defect based on specified logic. SOLUTION: An external address circuit 2 receives an address signal input to select a required memory cell of a memory cell array 1 through a connection switch circuit 6, an internal address circuit 3 and a decoder 4. A switch instruction circuit 5 selects a proper pattern among plural prescribed switch logic patterns of external/internal address by cutting a fuse to instruct to the connection switch circuit 6. For instance, by driving a physical defective address existing discretely into the area of the farthest address counting from '00' on a logical address, that is, (an upper part area), remaining addresses are used as the continuously accessible areas. At this time, a free address control circuit 7 makes a chip into a non-selection state when the upper part area is accessed.

Title: Automatic sheet feeder
Inventor: MORI HIROSHI
IPC: G03G15/00
Filed: 1991-10-30
Abstract: PURPOSE:To prevent multi-feed of sheets due to an excessive conveyance force and make the condition of conveyance stable by differentiating a conveyance force with respect to a first one sheet of the stacked sheets and to the remaining ones thereof. CONSTITUTION:Documents stacked on an original sheet placement base, after a set of documents have been sensed by a sensor S1, is conveyed, by semi- circular rollers 6, up to a separation roller 7a, and documents are fed between a contact glass 11 and a pressing plate 12 by a conveyance roller pair 8 and a guide roller 10. Thus, reading of picture image are performed. If the document set sensor S1 has judged that any document is present on the document placement base, a flag is set and, upon receipt of a paper sheet feed command, the flag setting is checked. If the flag is set, the rotation speed of the paper feed roller 6 is reduced to start a paper sheet feeding. If the flag is not set, the sensor S1 judges that the second and succeeding documents are present on the placement base, the rotation speed of the paper feed roller 6 is increased to perform feeding of paper sheets. Further, a sensor S2 is provided between the conveyance roller pair 8 and the guide roller 10 to check non-feeding of the documents having started being fed.

Title: Precipitation method of layer from vapor phase by means of plasma
Inventor: HAINTSU SHIYUTAINHARUTO
IPC: C23C16/452
Filed: 1992-09-29
Abstract: PURPOSE: To improve the quality of a layer by a method, wherein a reaction gas for activated neutral particles is decomposed by microwave energy bonded with thermal energy, and activated particles are guided to a reactor and a reaction gas which is not excited is put additionally into the reactor and then a layer is deposited by plasma deposition with RF energy which is coupled with thermal energy. CONSTITUTION: Reaction gases which are separately excited are together put into a reactor first. Besides processing gases, inactive gases can be excited in some cases. Inactive gases, such as argon and/or helium, are guided to a supply tube 7 through a supply tube 9 as in the case of processing gases. Gas which is not expected to be excited, such as silane, is supplied to a supply tube 8 through a supply tube 11. Gases other than those desired as reaction products are also generated, and these gases are exhausted by means of a pump 10. By this method, inactive gases can be excited separately under the most appropriate conditions.

Title: Underwater communication system
Inventor: SUZUKI MASAMITSU
IPC: H04B11/00
Filed: 1986-11-28
Abstract: PURPOSE:To execute a secure communication by transmitting a code corresponding to a switch input plural times to one switch input. CONSTITUTION:By operating a switch 1 an encoder circuit 3 is made to be started so as to generate a signal in a specified format. At this time, code information inputted by the input switch 1 is accumulated in a buffer 2 once and then inputted in the encoder 3. The buffer 2 outputs inputted information at intervals of a certain time plural times. Therefore the same code is transmitted plural times. Next, the encoder 3 executes a specified encoding to the signal, which is modulated, for example it is AM modulated, in a modulation circuit 4 and amplified in a power amplifier 5, so that an ultrasonic signal is radiated into the water from an ultrasonic transducer 7 through a circulator 6. Thus a wireless communication between divers, each other, under the water or the one between a diver and a person on the ship can be securely executed.

Title: Photosensitive resin
Inventor: YASUSATO TADAO
IPC: G03F7/028
Filed: 1991-10-31
Abstract: PURPOSE:To provide the photosensitive resin for hybrid lithography of UV light and electron beams. CONSTITUTION:While naphthoquinone diazide suppresses the alkali solubility of cresol novolak, a part 1a irradiated with the UV light is soluble in alkalis. An acid is generated from a 4-ditrichloromethyl triazine compd. by irradiation with the electron beams and the acid contalyst crosslinking reaction of the cresol novolak and a melamine compd. is generated by heating. A part 1b heated by the electron rays is, therefore, insoluble in the alkalis. The resin is thereafter developed by an aq. alkaline soln., by which a pattern 1C is formed. Since the photosensitive resin is constituted of the four components in such a case, the characteristics for the UV rays are optimized by the content of the naphthoquinone diazide. The characteristics for the electron beams are optimized by the kinds and contents of the acid generating agent and crosslinking agent. Then, the photosensitive resin having the good characteristics to two different light sources is easily obtd.

IPC: B29L17/00
Filed: 1989-10-31
Abstract: PURPOSE:To make a molding cycle shorter and improve the durability of a mold by constituting the mold cavity in use of specially plated bush materials. CONSTITUTION:A mold cavity is constituted of the materials of bushes 3, 4 in which an NiP plated layer 10 is given at least one the cavity surface of the surface of a copper base material 11 by an electroless phosphorus nickel plating process.

And, by uniforming the distribution of temperature on the cavity surface, deformations such as warpage or the like are reduced, which are caused by the thermal stress of molding. And, a non-crystal NiP layer 10 is hard to produce pin-holes and the like in comparison with crystal ones during the mirror grinding period, thereby obtaining mirror finish without defects.

Title: Variable wavelength semiconductor laser
Inventor: KOJIMA KEISUKE
IPC: H01S3/105
Filed: 1989-11-02
Abstract: PURPOSE:To enable wavelength variation of good reproducibility at a fast speed by providing a diffraction grating or a prism, a wavelength control part which consists of a transmission factor variable element which can change transmission factor electrically, and a reflectance variable element which can change reflectance. CONSTITUTION:Light of a wavelength corresponding to wavelength of lambdaa to lambdac, for example is diffracted to different directions by a diffraction grating 3 having dispersion characteristics of wavelength from a semiconductor gain medium 1 which produces gain through current injection; and is injected to transmission factor variable elements 4a to 4c whose transmission factors can be electrically changed respectively. At this time, if the transmission factor variable element 4a alone has high transmission factor and others has low one, light of wavelength lambdaa alone is selectively reflected by a recessed mirror 5. As a semiconductor laser resonator, it has high reflectance to a wavelength lambdaa alone and oscillates at the wavelength lambdaa. Then, if the transmission factor variable element 4b alone is put in a state of high transmission factor, an oscillation wavelength is switched to lambdab. Thereby, a wavelength can be changed with good reproducibility at a fast speed.

Abstract: PURPOSE:To obtain a small-sized and inexpensive mode change detecting apparatus, by a method wherein a change of a mode is converted into a change of intensity and detected by means of a multimode fiber having a light isolator, a mode scrambler and a light dividing unit. CONSTITUTION:A light 19 emitted from a semiconductor laser element 1 enters a light isolator 2.
