Title: Optical fiber connector, optical fiber and method for making light incident on optical fiber
Inventor: SASAKI HIRONORI
IPC: G02B6/32
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To improve connection efficiency between a multi-mode optical fiber and a single mode optical fiber by providing a numerical aperture conversion mechanism for converting a numerical aperture between a reduction optical system and the single mode optical fiber. SOLUTION: This optical fiber connector 100 is constituted of the multi-mode optical fiber (G1 fiber) 10, the reduction optical system 20, the numerical aperture conversion mechanism 30 and the single mode optical fiber (SM fiber) 40 by rough classification. That is, the numerical aperture conversion mechanism 30 for converting the numerical aperture is provided between the reduction optical system 20 and the SM fiber 40. In this case, as the numerical aperture conversion mechanism 30, a concave lens is used. Then, for emitted light emitted from the G1 fiber 10, the numerical aperture of the SM fiber 40 is converted to a pseudo large numerical aperture (pseudo numerical aperture) by the concave lens. Thus, light is made incident on the end face of the SM fiber 40, the end face of a core 42 in this case, more efficiently than before.

Title: Knocking control for internal combustion engine
Inventor: HASHIMOTO TORU
IPC: F02P5/15
Filed: 1990-03-19
Abstract: PURPOSE:To prevent the cost increase of a calculator by correcting the output of a knock sensor which forms a judgement standard for knocking towards higher value, when the generation of knocking of an engine is continued even if the ignition timing is delayed. CONSTITUTION:When the engine revolution speed is set between the previously set upper and lower limit values and the intake charging efficiency is larger than a previously set lower limit value, i.e., when it is judged that an engine 11 is in a knocking judgement region, the reduction of the output of a knock sensor is judged. If reduction is not generated, it is considered that the delayed angle quantity of the ignition timing is insufficient, i.e., the noise level V is set too small, and the renewed displacement quantity is calculated, and this value is stored in the RAM of an ECU 31. Accordingly, the need of a frequency filter for removing the noise component in the detection signal supplied from the knock sensor and the software for average-processing the detection signal of the knock sensor which passes through the frequency filter is obviated, and cost cut can be realized by a simple calculation device.

Filed: 1988-03-23
Abstract: PURPOSE:To obtain a high grade printing image by reducing the distortion of an image as much as possible, by taking out necessary data from the image signals of many lines corresponding to respective blocks separate in a main scanning direction to synthesize the image signal output corresponding to one line. CONSTITUTION:A scanning region is divided into many blocks, for example, five blocks A, B, C, D, E in a main scanning direction. Laser beam is modulated on the basis of the image signal of the original n-th line at the time of the (n+1)-th line in the blocks A, E, on the basis of the image signal of the original n-th line at the time of the n-th line as it is in the blocks B, D, and on the basis of the image signal of the original n-th line at the time of the (n-1)-th line in the block C. The corrected line is reduced in shift with respect to a reference line L to become the max. shift corresponding to respective 1/2 dots up and down. The original image signals are rearranged in a sub-scanning direction with respect to each of the regions separate in the main scanning direction and the image signal output at every line is synthesized.

Title: Production of high-density sintered body of silicon nitride
Inventor: KOBAYASHI KAZUO
IPC: C04B35/593
Filed: 1988-03-23
Abstract: PURPOSE:To obtain a high-density sintered body of silicon nitride by coating glass on the specific presintered body formed by molding of a powder mixture of the silicon nitride contg. the oxide of Y or Al as a sintering assistant and subjecting the sintered body to hot isostatic pressing. CONSTITUTION:The powder mixture of the silicon nitride which contains the oxide of at least the yttrium and/or aluminum as the sintering assistant and at which >=90% of which consists of an alpha phase is molded. This molding is presintered to obtain the presintered body adjusted to 20-60% rate of conversion of the silicon nitride to the beta phase. The glass is coated on this presintered body and said body is subjected to the hot isostatic pressing. The reason for limiting the rate of conversion to the beta phase to 20-60% lies in that the max. pore size remaining in the sintered body in the sintered body increases and the compacting is not enough if the rate is off said range. The sintered body is presintered prior to the hot isostatic press treatment of the glass capsule according to the process of producing the sintered body mentioned above and, therefore, the high-density sintered body of the silicon nitride is obtd. without having the influence of the acicular beta type silicon nitride.

Title: Data receiver, control method for the same and printer using the same
Inventor: SUZUKI NORIYUKI
IPC: B41J5/30
Filed: 1995-03-27
Abstract: PURPOSE: To improve the efficiency of reception processing by transferring data in a reception buffer to a memory without performing polling. CONSTITUTION: When the reception of data is started, those data are fetched into the reception buffer. When the data are received, a CPU investigates the contents in the reception buffer, namely, performs polling and when there are any data, length data at the prescribed position of received data are set to a register 26. Next, a comparator 27 is enabled and polling is stopped. Afterwards, the generation of a second interruption request is waited. During this waiting, data are successively received and when difference between a write pointer 17 and a read pointer 18, namely, the amount of received data is made equal with the register 26, a signal showing such a state is outputted from the comparator 27 and becomes the request of interruption to the CPU. When the interruption request is generated, the CPU reads data from the reception buffer and transfers them to a RAM.
