Patent JP-H01292777-A (JP)
Title: Spark plug
Inventor: BANDO YOSHIHIRO
IPC: H01T13/32
Filed: 1988-05-19
Abstract: PURPOSE:To achieve good flow between the inside room and the outside, and enable the oil, concentrated gas, etc., to flow out to the outside of the earth electrode by providing through holes in the earth electrode and thus establishing communication between the inside room, which is located inside of the earth electrode and in which the center electrode is disposed, and outside thereof. CONSTITUTION:A plurality of through holes 5 are provided in the earth electrode 3 to achieve communication between the inside room 4 and the outside (outside of plug). Accordingly, although the lubricating oil, rich mixture, etc., enter the inside room 4 once when the apex seal 12, sliding on the inner surface of the rotor housing, passes the plug position, they flow away outside because there is communication between the inside room 4 and the outside via the through holes 5. Thus, there will be no accumulation of oil, concentrated gas in the inside room 4 so that ignition can be effected without the center electrode 2 being covered with oil, concentrated gas, etc.

Title: Alignment accuracy measuring tool for inner lead bonding device
Inventor: KASHIMA NORIYASU
IPC: H01L21/60
Filed: 1988-05-20
Abstract: PURPOSE:To make it possible to accurately measure the alignment accuracy of an inner lead bonding device by forming an opening formed in an electrode attachment part in the same shape as that formed by connecting respective equivalent points of respective electrodes of a semiconductor element. CONSTITUTION:For a copper foil 12, is used one in which a square hole 13 having a side of the same dimension as a rectangular passing the center of an electrode 4 of a semiconductor element 5 is formed. A copper foil 12 is attached on one board surface of the periphery of an opening of a base 11, causing the square hole of the copper foil 12 to protrude to an opening 10a. The plating is performed on a portion where the copper foil 12 is exposed, and an electrode attachment 14 in place of inner leads is formed around the opening 2. That is, before inner bonding is started, the electrode 4 of the semiconductor element 5 is bonded to the electrode attachment of the base by an inner lead bonding device. Then, position relationships between the opening of this bonded base and the electrode are measured by a measuring instrument. The alignment accuracy of the inner lead bonding device itself is calculated from this measurement value. This makes it possible to accurately measure alignment accuracy.

Title: Picture processor
Inventor: MATSUNAWA MASAHIKO
IPC: H04N1/405
Filed: 1982-07-14
Abstract: PURPOSE:To obtain a picture of which gradation ability is sufficiently controlled, by using a dither matrix having non-uniform frequency distribution, and selecting the number of levels for A/D or D/A conversion more than the number of thresholds constituting said dither matrix. CONSTITUTION:Receiving an output signal of an oscillator 1, a CCD controlling circuit 3 outputs a picture signal to a CCD module 2. Receiving the outut of the oscillator 1, a counter 4 also outputs thresholds sequentially from an ROM5. An analog output from the CCD module 2 is converted into a digital data by an A/D converter 6, the digital data are compared with the output signal of the ROM5 by a comparator 7. When the compared result is larger than the selected threshold of the dither matrix, high level ''1'' is outputted, and when smaller than the selected threshold, low level ''0'' is outputted. A recording part 8 records data on the basis of a binary signal outputted from the comparator 7. Since the number of levels of the A/D converter 6 is seleted more than the number of thresholds, the effect of frequency distribution applied to the dither matrix appears on a picture sufficiently.

Title: Natural language processing system
Inventor: HIRAOKA TAKESUKE
IPC: G06F17/27
Filed: 1994-06-07
Abstract: PURPOSE:To efficiently and surely generate and select a construction tree. CONSTITUTION:A threshold corresponding to the number of the words of a sentence is calculated/set (S11), and a meaning check processing is executed when the construction tree is generated (S12) in the generation processing (S2) of the construction tree after the reading of the words (S1). The meaningful adaptability of the modification of the word concerned in the processing is checked (S121). When adaptability is 'NO', the number of subtractions, which is set by the classification of meaning check, is subtracted from the present evaluation point of the construction tree (S122), and whether the evaluation point of the construction tree is larger or smaller than the threshold (S123), is judged. When it does not satify the threshold, the construction tree is eliminated (S124). When the evaluation point of the construction tree is larger than the threshold, the adaptability of the modification of the construction tree is recognized and the construction tree is grown (S125). The construction tree whose evaluation point is the largest is finally selected as the construction tree having adaptability in terms of meaning (S13).

Title: Polling system in data transmitter
Inventor: SUGIYAMA SHIZUO
IPC: H04L12/40
Filed: 1991-04-26
Abstract: PURPOSE:To simplify the processing by deciding a polling period for a time mt (m-sets are an average number of MODEMs for N lines) and returning a response representing it when data of a slave set is not entirely collected at polling through lines whose number of MODEMs is in excess of (m). CONSTITUTION:In the case of n-sets of MODEMs per line, let a data collection time between a master MODEM MS and a slave MODEM SL be (t), let an average number of slave MODEMs be (m), then a polling period is set to mt. When data of the m-sets of MODEMs are collected, a polling from a line connector NCOP reaches the master MODEM, and since not all data is collected, a response V representing the absence of the data is returned. The master collects the data for the n-sets of the MODEMs and since the data for the n-sets of the MODEMs are collected at a succeeding polling, the data is given to the device NCOP. Thus, the data processing and communication procedure are simplified by returning the response V in this way.

Consequently, contact failure due to the intrusion of dust can be prevented.
