Title: End tab for welding
Inventor: TSUJI TATSUO
IPC: B23K37/06
Filed: 1979-07-28
Abstract: PURPOSE: To prevent the production of welding defects by using the titled tab obtained by incorporating water glass to refractory material of the specific grain size constitution, molding the mixture to a desired shape and solidifying the molding by a CO 2  gas.  
     CONSTITUTION: Water glass is incorporated at 5W20wt% to refractory material powder prepared by dry compounding in such a manner as to have the grain size constitution of ≤50% of the grains finer than 48 mesh and smaller than 270 mesh. After the mixture is molded to a desired shape, the molding is solidified and dried in a CO 2  gas atmosphere. If this end tab is used, the oxidation of the joint end faces of base metals is prevented because the gas generated in the welding arc atmosphere is CO 2 , thus the production of welding defects such as blowholes may be effectively prevented.

Title: Tatami mat
Inventor: SUGIMOTO AKIRA
IPC: E04F15/02
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To manufacture a thin, lightweight, highly rigid tatami mat resistant to moisture and excellent in durability, compared with a straw mat by constituting a mat bed from a kaoliang board having a specified specific gravity or a kaoliang board having a timber single board stuck to one side or both sides thereof. SOLUTION: A kaoliang board 1, which is finished flatly by cutting the irregularities on the surface, can be made into a kaoliang board 1 having no clearance by sticking an extremely thin timber single board to one side or both sides thereof. Since the specific gravity of the kaoliang board 1 is rather larger than straw, use of a kaliang board 1 having a specific gravity of 0.38 or less is required when the thickness can not be changed in the renewing of an existing tatami mat. A tatami bed A is manufactured by putting an urethane cushion material 2 on the side forming the tatami facing of the kaolang board 1, putting a waterproof paper 3 reinforced by a cloth consisting of polypropylene split yarn on the side forming the tatami back, and sewing them together with a propylene tatami thread 4.  A tatami mat using the kaoliang boa 1 is thin, lightweight, resistant to moisture, excellent in durability, inexpensive, and free from the fear of propagation of harmful insects.

IPC: G06K9/03
Filed: 1983-05-31
Abstract: PURPOSE:To shorten the processing time required for reference to a dictionary by rewriting the dictionary within an internal memory to a dictionary of the 2nd standard after the character reading is through on a slip with reference to a dictionary of the 1st standard then reading again collectively the rejected characters. CONSTITUTION:The data 71 of a dictionary of the 1st standard is transferred to an internal memory 5 of a dictionary retrieving part 4. Then the reading is started for characters on a slip A through a scanner 1, character separating part 2, feature extracting part 3 and a dictionary retrieving part 4. The code data CD of the read characters are successively filed to a file memory 6. In this case, the control data within a control data memory part 9 is loaded into a working area 73 of an external memory 7 in response to a rejection signal R which is produced when the recognition of a pattern is impossible at the part 4. Then a map is produced for rejected characters. When the reading is through with reference to the 1st standard dictionary,the data 72 of the 2nd standard dictionary is transferred to the memory 5. Then the rejected characters are read again based on the control data 73.

Abstract: PURPOSE:To add an error correction protocol function to a data terminal device by providing a data terminal device interface section, a buffer memory section, an error correction protocol adaptor processing either coding or decoding and executing an error correction protocol, and a line interface. CONSTITUTION:In an adaptor 4, a communication data B sent through a line 3 is received by a line interface section 9, the data is decoded by an error correction protocol adding section 8 to obtain a communication data A.

Title: Signal generator
Inventor: TODA KOICHI
IPC: H03L7/16
Filed: 1988-04-20
Abstract: PURPOSE:To generate continuously a signal of a stable desired frequency simply with low cost in a prescribed step for a prescribed band by using a switching signal from a control section in response to the frequency setting so as to supply an output signal of a mixer selectively two feedback paths. CONSTITUTION:A switch 17 throws an output from a mixer 12 to the position of a phase detector 14 by using a switching signal from a control section 19 in the 1st state where a signal of a prescribed frequency is outputted from the mixer 12 as a feedback signal. Thus, a phase detector 14 compares the phase of the output signal of the mixer 12 with that of the reference signal, supplies a signal based on the result of comparison to a voltage controlled oscillator 11 to control the oscillated frequency. Thus, a signal of a desired frequency at a region of nnot equal to 0 is outputted from the oscillator 11. Moreover, the switch 17 throws the output from the mixer 12 to the position of the oscillator 11 by using the switching signal from the control section 19 in the 2nd state where the DC signal from the mixer 12 is outputted as the feedback signal. Then the oscillated frequency of the oscillator 11 is controlled by a DC signal from the mixer 12. Thus, the signal of the desired frequency in the region of n=0 is outputted from the oscillator 11.

Filed: 1989-04-17
Abstract: PURPOSE:To smoothly enable automatic control of load by providing a mechanism which is dislocated in the direction of rotation according to load of rice polishing between a center shaft and a rice milling roll. CONSTITUTION:When a hopper 46 is opened and unpolished rice 47 is supplied, this unpolished rice 47 is supplied into a grain feed chamber 3 and sent to the lower part by the grain feed screw 7 of a grain feed roll 5 for lower feeding and introduced into a polishing chamber A. Unpolished rice is agitated by the slantingly projected line 8 of a rice milling roll 6 in the polishing chamber 4. When rice polishing is progressed, load resistance is increased and the feed rate due to the grain feed screw 7 of the grain feed roll 5 is made plenty and reaction force is enhanced. Dislocation is caused between a hollow vertical shaft 9 and a driving shaft 13. Thereby the hollow vertical shaft 9 descends and both the grain feed roll 5 and the rice polishing roll 6 are moved to the lower part and polished rice is allowed to fall. Thereby miniaturization is enabled and precision enhanced.

Abstract: PROBLEM TO BE SOLVED: To improve a mechanical strength of a connecting portion and to prevent a crosstalk from occurring by conductively connecting a flexible cable between the portion and a connecting area of the vibrator through an anisotropically conductive layer, and embedding between the vibrators with a polymer bonding agent for constituting the conductive layer. SOLUTION: A polymer material excluded from opposed regions of a segment electrode and a connecting portion 33 of a flexible cable 13 flows to a gap between piezoelectric vibrators, and conductive particles are existed in a high density at the opposed regions between the electrodes and the portion 33 of the cable 13 to generate conductivity. The material flowed to and solidified in the gap between the vibrators to the opposed regions between the electrodes and the portion 33 increases its mechanical strength by connecting the vibrators to one another by a non-vibrating region. A vibration wave is propagated to the fixed substrate side as the vibrator 9 is contracted and extended, but absorbed by viscoelasticity of the material, thereby preventing a crosstalk.
