Title: Butt welding that enables all position welding
Inventor: KUWAYAMA NORIO
IPC: B23K9/16
Filed: 1981-12-15
Abstract: PURPOSE:To enable all position butt welding simply by performing AC gas  shielded arc welding making the quantity of slag forming substance of a combined wire and the width of I-shaped groove satisfy a specified relation. CONSTITUTION:An I-shaped groove having root face gap of 2-20mm. is welded by gas shielded arc welding under the following condition applying AC to a combined wire in which substance that contributes formation of slag in the flux is limited within the range of 0.3-1.5% in wire weight. The relation to be satisfied is (S-6)<=G<=(S+6.7) (S: the quantity of substance that contributes to formation of slag, wire weight %, G: root face gap, mm.). Then, molten metal in the groove becomes held by surface tension of the slag. Thus, welding of horizontal position, vertical position and overhead position can be performed efficiently with a simple device preventing dripping of molten metal.

Title: Radio video signal transmitter-receiver
Inventor: NISHIMURA RYUSHI
IPC: H04B1/707
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To realize two-way communication for a video signal stably. SOLUTION: The transmitter-receiver is made up of an image pickup means 1 such as a video camera, a coding means 2 compressing an information quantity of a video signal outputted from the image pickup means, a means 3 modulating the coded signal by a spread spectrum system, an antenna 1 sending/ receiving the signal, and means 4, 5, 6 demodulating and reproducing the video signal from the received spread spectrum signal. As a result, since the information quantity by coding is reduced before spread spectrum processing, it is not required to process extreme high frequency signals in the case of simultaneous transmission and reception and stable 2-way communication is realized.

Title: Information reproducing device having duplicate limitation function
Inventor: KURODA KAZUO
IPC: H04N5/85
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To prohibit reproduction of duplicated digital video information by directly recording an RF signal recorded on a digital disk on another digital disk. SOLUTION: A reproducing device 50 decides whether or not digital video information DP is prohibited from duplicating, etc., according to a digital watermark, etc., which are buried in the information DP. Further, the device 50 detects whether a DVD to be reproduced is a DVD only for reproduction of a recordable DVD through a disk detector 70. Thus, it is possible to detect that digital video information which is prohibited from duplicating ignores duplicate prohibition and is recorded on a recordable DVD.

Title: Opening door, blower unit, heater unit, and air conditioning unit
Inventor: NAGANO HIDEKI
IPC: B60H1/00
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To prevent a sound absorbing member from peeling off, and improve sound absorbing effect without increasing ventilation resistance in an inner space of a casing. SOLUTION: A door composed of a shaft 10 rotatably provided on a blower unit case 1, a door main body 11 provided on the shaft 10 and having a recessed part 14, a sound absorbing member 12 provided on one surface 11a of the door main body to fill the inside of the recessed part, and a seal member 13 provided at a circumferential edge part of the other surface of the door main body 11 is used as an inner/outer air change over door 5 of a blower unit 2. Since thickness of the sound absorbing member 12 can be large, sound absorbing effect is improved. However, as thickness of the inner/outer air change over door 5 is not increased, ventilation resistance of an inner space 6 of the blower unit case 1 is not increased.  Different from a conventional constitution in which a sheet type sound absorbing member is bonded to a circumferential edge part of one surface of a door main body, peeling of the sound absorbing member 12 to cause the sound absorbing member 12 to become a source of noise is eliminated.

Title: Data collector
Inventor: JIEEMUZU RICHIYAADO HARUSARU
IPC: H04J99/00
Filed: 1981-12-17
Abstract: Apparatus for gathering data about a plurality of chemical or physical conditions, e.g. on industrial plants, utilizes a plurality of passive optical sensors. Light for the sensors is provided by a common broadband source, and distributed by an optical fiber from which light of a selected color is withdrawn for each sensor in turn, the color selected for each sensor being different from that selected for the other sensors. Each color is modified by its respective sensor as a function of changes in the conditions applied to the sensor, and all the modified colors are conveyed along a common data bus to be demultiplexed and the data displayed. The colors may be supplied by the data bus to detection means simultaneously or sequentially. Passive optical sensors avoid electrical interference and incendiary risks due to electrical sparking, and color multiplexing avoids difficulties associated with other forms of multiplexing in plant environments.

Title: Joining device for pulled vehicle
Inventor: UCHIYAMA TOMIO
IPC: B60D1/02
Filed: 1986-08-30
Abstract: PURPOSE:To improve a working efficiency and safety by providing a stopper on a U-shaped joining member in an free extraction-insertion manner, and locking or releasing a rotation of a joining pawl member by the extraction- insertion operation, in a joining device for pulled vehicles joined to passenger tractors for a farming. CONSTITUTION:A pulling upward of an eye-bolt 56 and an extracting of a stopper 52 cause the stopper 52 to be released from a stopper abutting part 42. This allows a pawl 36, 36 to rotate by a spring 46 until the abutting part 42, 42 was abutted. Therefore, a pawl part 38, 38 separates, a U-shaped groove 32 opens, and a tractor 14 joining member becomes to be acceptable. And the insertion of a pin 26 causes the rotation of the pawl 36, 36, and the pawl part 38, 38 closes the U-shaped groove 32. This causes the opening of the abutting part 42, 42, then the insertion of the stopper 52 causes the locking of the pawl 36, 36, and the U-shaped groove 32 is kept in a closed state. This constitution enables the improvement of safety and a working efficiency.

Title: Electroacoustic transducer
Inventor: JIEI FUREMINGU DEIASU
IPC: B06B1/06
Filed: 1981-12-18
Abstract: PURPOSE: To shorten the attenuation time of the vertical mode, by making running  paths of the vibrated wave of the surface mode, which plural electroacoustic transducers vibrating in a plane vertical to a supporting member generate in both directions, up to both adjacent electroacoustic transducers different from each other.   
     CONSTITUTION: Piezoelectric crystals T 1 ∼T 6  are stood in parallel with a sound absorbing member 14 through insulating layers I 1 ∼I 6 , and a groove S 2.3  between piezoelectric  crystals T 2  and T 3  and a groove S 4.5  between piezoelectric crystals T 4  and T 5  are  extended to the sound absorbing member 14. When the piezoelectric crystal T 3  is  vibrated in the thickness mode by an electric signal, a vibrated wave of the surface  mode is generated by this vibration and passes through paths of arrows P 1  and P 2   indicated by broken lines and is reflected by piezoelectric crystals T 2  and T 4  and is  returned to the piezoelectric crystal T 3 . Since grooves S 2.3  and S 3.4  are different in  depth, phases of the vibrated wave of the surface mode returned to the piezoelectric  crystal T 3  through paths P 1  and P 2  are different from each other, and they are cancelled by each other, and therefore, the influence upon the vibrated wave of the thickness mode of the piezoelectric crystal T 3  is very great, and the attenuation time is  shortened. Thus, the resolution is improved.
