Title: Bigram dictionary, miniaturizing method therefor, method and device for recognizing processing for handwriting character
Inventor: NAKAGAWA MASAKI
IPC: G06K9/72
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To attain the miniaturization of a bigram dictionary, which is used for context post-processing in the recognizing processing of handwriting input characters, and to facilitate packaging into a portable computer. SOLUTION: At the time of miniaturizing the bigram dictionary which stores the link information of two characters found from a learning text, the value of its probability is quantized into prescribed step number (256 steps, for example), while using hybrid probability, that value is expressed for a short word length (1 byte, for example), and concerning the probability smaller than a prescribed value, such information is not registered on the bigram dictionary. Thus, the dictionary can be miniaturized without damaging a recognition rate.

Filed: 1989-10-04
Abstract: PURPOSE:To measure the length of the remaining sound part of a supporting plate by inserting a radioisotope ray source into a heat transfer tube, inserting a radiation measuring instrument into the other heat transfer tube adjacent to the heat transfer tube and measuring the radiations radiated by the ray source. CONSTITUTION:The radioisotope ray source 2 which is provided at the front end of a hose 4a for coupling and has further a probe 1 for low-frequency eddy current flaw detection via a hose 4b for coupling at the front end thereof is inserted through a water chamber 7 by the hose 4a into the heat transfer tube penetrating through the supporting plate 9 to be measured. A supporting plate signal is generated when the probe 1 arrives at the supporting plate region. The ray source 2 arrives at the center 9a of the supporting plate when the ray source is inserted by the spacing L1 between the ray source 2 and the probe 1 from this position. The radiation measuring instrument 3 constituted in the same manner is inserted into the adjacent heat transfer tube and is similarly positioned. There is a specified relation between the transmission rate of the radiations which are received by the measuring instrument 3 and radiated by the ray source 3 and the length of the remaining sound part of the supporting plate 9 and, therefore, the corroding part 10 at the center 9a can be detected by the radiations received by the measuring instrument 3.

Title: Ignition device for initiation element
Inventor: OGASAWARA HAYATO
IPC: B60R21/16
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of accidental firing due to the runaway and noises of a CPU by driving the ignition device with a coded expansion signal decoded. SOLUTION: A CPU 13 judging a collision, generates an expansion signal coded in accordance with specified codes, a decoder 20 having received the expansion signal, decodes the expansion signal so as to allow an ignition signal to be outputted, and an ignition device 14 to be actuated by the ignition signal, energizes an initiation element 15 so as to initiate it.  Different from a device in the past, which directly drives the ignition device 14 by the use of a simple expansion signal expressed by (0) or (1) in binary notation, since the ignition device 14 is driven by the ignition signal obtained by letting a coded expansion signal be decoded by a decoder 20, it can be prevented that the ignition device 14 is erroneously driven due to external noise, or due to the runaway of the CPU 13 itself, the accidental firing of the initiation element 15 caused by electromagnetic wave obstruction and runaway, can thereby be surely eliminated.

Title: Manufacture of semiconductor device
Inventor: YAMASHITA TSUTOMU
IPC: H01L21/52
Filed: 1986-10-29
Abstract: PURPOSE:To prevent incomplete wire bonding to bonding pads and electrodes on a substrate by mounting a semiconductor pellet on the substrate with silver paste and baking it under subatomospheric pressure. CONSTITUTION:A substrate S where a pellet P is mounted by using silver paste is put in a high-temperature tank; the inside of the high-temperature tank is evacuated to a pressure of lower than the atmospheric pressure, e.g. 0.1-0.2 atm. Then, the inside of the high-temperature tank is heated at 100-150 deg.C by keeping the reduced pressure. After this temperature has been kept for 1-2 hours, the inside of the high-temperature tank is kept leaked and is then returned to the atmospheric pressure. Then, the substrate S where the pellet P is mounted firmly with the baked silver paste is taken out from the high- temperature tank. By this method, the inside of the high-temperature tank is never filled with an out-gas which is generated during the baking process of the silver paste. As a result, the out-gas of the silver paste does not adhere to the surface of the semi-conductor pellet and to an electrode part on the substrate; the defective adhesion of a bonding pad part and the electrode on the substrate to a bonding wire is eliminated.
