Title: Apparatus for detecting abnormal vibration of engine
Inventor: TANAKA MITSUO
IPC: G01H17/00
Filed: 1987-09-24
Abstract: PURPOSE:To obtain an inexpensive apparatus having good detection accuracy, by converting the detected vibration of an engine to a component distribution signal at every predetermined frequency to compare the same with a reference value. CONSTITUTION:A programmable band-pass filter 35 divides as frequency band FB from 100 Hz to 10 kHz, for example, into 25 sections by the control of a CPU 32 and inputs the detection output of an electromagnetic pickup MP 4 while changes over the center frequency thereof at every one rotation of an engine in synchronous relation to the output of the MP. the passing signal of each FB is converted from a square average value to a smooth DC signal by an RMS/DC converter 36 while said DC signal is converted to a digital signal by an A/D converter and edited by a CPU 32a to be converted to a component distribution signal divided at every predetermined BF. At first, the vibration of the engine at a normal time is preliminarily detected by an MP 1 and processing is performed while the FB of the filter 35 is changed over to obtain a component distribution signal which is, in turn, stored in the CPU 32 as a reference value. By this method, the engine is operated under the same operating condition as that when the reference value is stored to detect the vibration thereof by a detector 1 and the detected value is compared with the corresponding waveform of the reference value and the presence of abnormality is judged from the difference between both of them.

Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a novel drawing method by which efficiency of cutting and line drawing in a next process is improved and effective length of a preform for an optical fiber can be lengthened in a drawing of the preform for the optical fiber. SOLUTION: One end of the preform for the optical fiber is grasped with an upper chuck, another end thereof is grasped with a lower chuck respectively and the upper chuck and the lower chuck are moved at a speed different from each other while heating them by a resistance furnace. Thereby distance between the upper chuck and the lower chuck is enlarged to make the preform for the optical fiber a stretched body. In this case, preform is drawn so that the drawer body can be bound at a position to be cut of a stationary part of the drawn body.

Abstract: PURPOSE:To facilitate information exchange between users by displaying the color or the type of the displaying area in a picture of a station which an information editing program uses by distinguishing them according to whether the editing program in question is interlocked with the program on other station or not and so on. CONSTITUTION:The stations 1000 to 3000 in which the user inputs and outputs a voice or inputs and outputs information to the program are connected to an information communication network 4000. Interactive control program 1400, 2400, 3400 analyses input from the user of the station, and if the input is an interlocking request, it prepares on inter-program communication channel, and updates the information related to the connected other party of an interlocking correspondence table, and changes the color or the form of the information displaying areas the editing program uses after checking the connection state of a voice exchange channel, and in addition, sets its own state at an interlocking state. In the case where an interlocking stopping request arises, it releases the inter-program communication channel, and simultaneously, changes the color or the shape of the information displaying area, and sets its own state at a non-interlocking state. Thus, the information exchange between the users can be facilitated.

IPC: G11B7/24
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide an optical information recording medium provided with limitations in the number of reproduction times. SOLUTION: A mask layer 3 of the optical disk which is formed by successively laminating the mask layer 3 and a reflection layer 4 on a light transparent substrate 2 previously recorded with information signals by micro-rubbed shapes consists of a thermoplastic material which reproduces the information signals by substantially reducing the diameter of a light spot and emitting a laser beam to a reflection layer 4 side to emit the returning light from the reflection layer 4 side to the substrate 2 side by the substantial increase in the light transmittance of part of the irradiated portions when the temperature of the irradiated portions to be continuously irradiated with the laser beam for reproduction made incident from the substrate 2 side rises to a decoloring temperature or above and which loses the ultra-high resolution function of the disk when the internal composition is  changed by the heat accumulated in the irradiated portions after the reproduction.

Title: Magnetic disk device
Inventor: ONO KOICHI
IPC: G11B21/10
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To make possible continuous data write-in/read-in operation by using a result of operation required for following operation when a magnetic head follows up an optional track. SOLUTION: Information recorded on a magnetic disk 2 is read out by the head 1, and at this time, a head IC 4 outputs a read-out signal of the head specified by an MPU 8 to a read/write IC 5. The IC 5 amplifies the signal to output it to a servo signal detection circuit 6. When the detection circuit 6 detects the signal with a fixed and certain decided pattern existing on a head of a servo signal from the inputted read-out signal, it demodulates an absolute track number inputted after the detected signal, and generates a position deviation signal from a position deviation signal detecting burst signal succeeding to it, and outputs it to an A/D converter 7 to start the A/D converter 7. The servo detection circuit 6 outputs an interruption signal to an MPU 8 regardless of the head selected then.

Title: Semiconductor nonvolatile memory device
Inventor: TANAKA TOSHIHIRO
IPC: H01L29/792
Filed: 1989-09-20
Abstract: PURPOSE:To contrive the reduction of a charging current and a discharging current from a memory array at an erasing time by dividing the memory array part into two or more smaller blocks than the part of the memory array to be erased and erasing successively electrically the divided blocks. CONSTITUTION:As for the divided blocks B1-B16 of the memory array, first the divided block B1 is erased, and the next dividing block B2 is erased by providing time difference at e.g. the dividing block B1-B4 i.e. when a part S of the memory array is the specified erasing range. Further by providing the time difference, the dividing block B3 is erased, and by providing the time difference, the dividing block B4 is erased. Consequently, the number of the source, the drain or the exclusive gate line simultaneously applying the erasing high voltage is reduced, and the electrostatic capacity accompanying this can be reduced. In such a manner, the charging current and the discharging current from the memory array at the erasing time are reduced.

Title: Semiconductor integrated circuit mounting device and its manufacture
Inventor: IINO KAZUHIRO
IPC: H01L21/60
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of the connection reliability of solder by preventing the progress of oxidation on the surface of the solder. SOLUTION: When a semiconductor integrated circuit element 5, the semiconductor circuit element of which is mounted on a first substrate 3 is mounted of the second substrate 2 of the whole device 5, the upper and lower projections 13 and 12 of a first substrate 1 are respectively welded to a solder 14. The upper projection 13 is welded to the circuit device 5 via the solder 14 and the lower projection 12 is welded to the second substrate 2 via the solder 14. Since the upper projection 13 is welded by locally heating the projection 13, the heat energy produced when the projection 13 is heated is not transferred to the lower projection 12. Therefore, the lower projection 12 is not oxidized, and welding reliability will not deteriorate chemically.  The welding reliability will not deteriorate physically also, because the projections 12 and 13 turn into a flexible structure, when the projections 12 and 13 heated due to a glue-like material held between the projections 12 and 13 and the projections 12 and 13, and the lower projection 12 is welded uniformly to the second substrate 2 and will not cause dimensional variation, when the projection 12 is welded to the second substrate 2.
