Title: Welding method for narrow edge due to consumable electrode type gas shield arc
Inventor: IWAMI HIROSHI
IPC: B23K9/16
Filed: 1981-06-05
Abstract: PURPOSE:To obtain an indefectible high-quality welded joint, by using an AC provided with a refiring means as power and using a solid wire as a consumable electrode. CONSTITUTION:A torch 2 where a solid wire is inserted, is inserted between narrow edges, and the solid wire is used as a consumable electrode 3. An AC current is applied across a base plate 1 and the torch 2. A pulse voltage is generated from a pulse generating device 9 when the welding voltage is near zero. Then, an AC arc is continued without flux. Thus, an indefectible high-quality welded joint is obtained.
Patent JP-H04318706-A (JP)
Title: Input circuit
Inventor: OIKAWA TAKESHI
IPC: H03K19/0175
Filed: 1991-04-18
Abstract: PURPOSE:To prevent malfunction of an internal circuit of a post-stage even when a high potential power supply potential or a ground potential is fluctuated by providing a capacitor at least between an input terminal and a high level power supply terminal. CONSTITUTION:With an input signal VIN set to a high level, when a ground potential GND is increased, a theoretical threshold level of a CMOS inverter 1 is fluctuated. In this case, the fluctuation in the potential GND is sent to the signal VIN via a capacitor C2 and the level of the signal VIN is fluctuated. Thus, the theoretical threshold level of the CMOS inverter 1 does not exceed the signal VIN, the inverter 1 does not output an inverted potential and no malfunction takes place in the post-stage circuit connecting to an output terminal 5. Moreover, with the signal VIN set to a low level, a change in the high potential power supply potential VCC is sent to a line of the signal VIN via a capacitor C1 and the signals are changed simultaneously. Thus, the theoretical threshold level of the CMOS inverter 1 is not lower than the level of the signal VIN.

Title: Auto-tensioner
Inventor: OTA HIDEYUKI
IPC: F16H7/12
Filed: 1995-04-11
Abstract: PURPOSE: To facilitate dimension accuracy management inexpensively, by providing a pair of friction members along between both the ends of an oscillating member alienting respectively in a first axis direction with each other, and supporting an oscillation member in the first axis direction via both the friction members. CONSTITUTION: Since first and second friction members 100 and 110 are arranged along both the end surfaces 50a and 50b of an oscillation body 50 alienating in a first axis L1 direction with each other, the respective friction members contact at both the end surfaces 50a and 50b of the oscillation body 50. Consequently, special polishing work can be eliminated to both the end surfaces of the oscillation body 50 to make a work cost inexpensive. Also, since both the end surfaces 50a and 50b of the oscillation body 50 are nipped by the friction members 100 and 110 to support the oscillation body 50, the distance between both the friction members is inevitably prolonged, thereby prolonging an interval for positioning the oscillation body 50 to make it difficult to be tilted.  Consequently, desired damping force can be obtained without strictly setting the dimension accuracy management of the respective parts such as the friction member.

Inventor: FUJITA JIYUNZOU
IPC: G11B15/61
Filed: 1982-05-20
Abstract: PURPOSE:To press-contact assuredly a pinch roll to a capstan, by fixing an aluminum die cast support block to a chassis and sliding a metallic parts which supports the pinch roll with guidance of the support block. CONSTITUTION:A pinch roll 57 which holds horizontally a rotary shaft above a tape guide path and shunts before loading is held horizontally by prescribing the positional relation between a hanging metallic parts 61 and a pulling metallic parts 63 for a holding metallic parts 59. When a pulling shaft 70 is moved back, the parts 63 pulls rotary arms 62 and 62 and turns the parts 59. Thus the roll 57 is set opposite to a capstan 58. Then the arms 62 pull the parts 59 when the shaft 70 moves back further. Thus the lower part of the roll 57 touches first the capstan 58, and the whole part of the roll 57 is press-contacted to the capstan 58.

Title: Freqeuncy discriminator
Inventor: MIZUNO ATSUSHI
IPC: H03D3/00
Filed: 1991-03-26
Abstract: PURPOSE:To realize the frequency discriminator for plural single-tone signals with less hardware by utilizing a phase error signal in a phase locked loop circuit so as to discriminate the frequency. CONSTITUTION:A single tone signal to be discriminated is inputted to a phase locked loop circuit 3 from an input signal terminal 1, and the circuit 3 extracts a phase error signal 5 between a phase of the received single tone signal and a phase of a self-running oscillating frequency in the circuit 3. The signal 5 is inputted to a phase error identification circuit 4, which discriminates a frequency of the input single tone signal. The phase difference is fed back in the circuit 3 so that a frequency and a phase of the oscillator in the circuit 3 are always coincident with a frequency and a phase of the input signal. That is, since the phase difference signal is given as a signal representing a difference between the self-running oscillation frequency and the frequency of the input signal in the circuit 3, the circuit 4 discriminates the frequency of the input signal by using the phase difference signal.

Filed: 1994-04-25
Abstract: PURPOSE:To prevent connection caused by wrong dialing by retrieving a registered name corresponding to a telephone number while using a retrieving means, and reporting the relevant name to a caller with a voice before a call is connected to a call incoming person as a name registered person. CONSTITUTION:Corresponding to a contracted telephone number, its own name is registered in a voice message registering part 1 with the voice and stored in a voice message storage part 2. A logical/physical number converting part 3 converts the call originating telephone number to the contracted telephone number corresponding to this and dispatches it to a voice message retrieving part 4. The retrieving part 4 retrieves the voice message while referring to the correspondence table of contracted telephone numbers and voice message numbers in the storage part 2. When there is the voice message, it is extracted by the retrieving part 4, transferred to a voice message reproducing/transmitting part 5 and transmitted to a line. The name of the call incoming person transmitted to the line is received by a call originating person, and the call originating person recognizes whether the destination of call incoming is right or not. Thus, the wrong connection to the call incoming person can be prevented without troubling the call incoming person.
