Title: Preparing method for heat-sensitive head
Inventor: FUJIWARA TAKEJI
IPC: B41J2/335
Filed: 1979-03-28
Abstract: PURPOSE:To prevent the accumulation of waste of heat-sensitive paper on the surface of a heater part and obtain a heat-sensitive head with good quality of printed picture by forming a convex shape of parts of acid-resistant layer and antiabrasive layer corresponding to the heater part. CONSTITUTION:The preparing method for the captioned device is similar to the existing ones so far as a glaze layer 2, a resistor 3 and an electrode 4 are formed on one surface of a substrate 1. In addition to the above, an acid-resistant layer 5 is formed to be a film thicker than that of the electrode. Next, by using an ordinary photoengraving technique, a photoresist mask is formed on the part of the acid- resistant layer corresponding to the resistor, while the other part of acid-resistant layer that is not covered by the photoresist mask being removed up to the depth more than the thickness of the film of electrode by the etching method by using an etching liquid of buffer. Then, the photoresist film is removed and an antiabrasive layer 6 is formed to be a film by the spatter method and the like.

Title: Screw body with washer and method of jointing thereof
Inventor: IKEDA KATSUMI
IPC: F16B39/26
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To enable the state of joint completion of a screw body by visual observation thereof after completion of the work by fixing the end part of outside coating member by means of a washer seat surface and the surface of a commodity and pulling to break the outside coating member in the circumferential direction by means of the rotation of the screw body during a period until tightening is further progressed to achieve very tight jointing state. SOLUTION: When the end part 2a of an outside coating member 2 makes contact with the surface of a commodity b so as to be in its fixed state by being pinched between the surface of the commodity b and the seat surface 3a of a washer 3, the end part 2a of the outside coating member 2 is also prevented from its movement in the rotational direction together with its axial movement. When the tightening is further progressed up to the final regular tightening by means of a tool 6, a screw body 1 becomes in its tightly clamped state. Then, in the vicinity of the washer 3 and the washer 1a of the screw body 1, a drawn and cut phenomenon occurs on the outside coating member 2 being pinched between the surface of the commodity b and the seat surface 3a of the washer 3, which is divided into a residual part 2c and a separated part 2e.  And since they fall down from the screw body 1, it can be recognized by external visual observation that the screw body 1 after the end of clamping is certainly tightened firmly.

Title: Synchronizing control system of cassette type magnetic tape device
Inventor: OOTA MASATAKA
IPC: G11B27/28
Filed: 1984-02-29
Abstract: PURPOSE:To assure the synchronizing control in a data reading mode by detecting a synchronizing character corresponding to a data frame on a data track only in a range limited by the relative position with a marker. CONSTITUTION:Both a data track TD21 and a marker track TM23 are recorded on an audio cassette type magnetic tape CMT. Then data records 221, 222- are recorded on the TD21; while frames 321, 322- are recorded to a record 22i. A marker 24 is recorded on the TM23 corresponding to a frame 32i. When a frame synchronizing character FSYN41 corresponding to the frame 32i is detected, a CMT controller 72 controls a CMT drive 73 according to a reading command sent from a CPU71. Then the controller 72 detects the FSYN41 only in a range of 4 bits in front and rear positions respectively centering on a marker end point after detection of the marker 24. Thus the synchronizing control is assured in a data reading mode.

Filed: 1981-03-16
Abstract: PURPOSE:To maintain stable adhesive strength by superposing parts to be joined which have joining materials stuck on a joint part, and melting the joining materials by feeding electric current by using two electrode rods. CONSTITUTION:On the joint part of a quartz oscillating piece 1, lead wires 5 and 6 which have joining materials stuck are superposed as parts to be joined. Then, electrode rods 14 and 15 are brought into contact with the tip part of the lead wire 5 and the root part close to an airtight terminal 4, and a low voltage is applied between both the electrodes to heat the lead wire 5 momentarily. As a result, the joining material stuck to the lead wire 5 is molten to stick the joint part of the quartz oscillating piece 1. Similarly, the lead wire 6 is also treated. Thus, the small-current electrode rods are used and electric current is fed in a short time to melt the joining material for connection, so that invariable stable adhesive strength is maintained.

Title: Measurement of depth of penetration
Inventor: WADA KOUICHI
IPC: B23K31/00
Filed: 1984-02-29
Abstract: PURPOSE:To enable accurate measurement of the depth of penetration of a weld part at a bridge girder or the like by prescribing the range of obtaining a flaw detection data for the height of bottom surface echo. CONSTITUTION:First, from a plotter display of the height of a bottom surface echo at the scanning of a probe 5 in the direction X, the range DELTAX of obtaining data for the height HB of the bottom surface echo is determined to set and then, the probe 5 is moved in the direction X' to be set at the position of starting the scanning. Then, the probe 5 is scanned in the direction X. At this point, as the probe 5 enters the range of measuring the height HB of the echo, an automatic decider starts to take in the echo height HB to determine the position P1 at which the echo height reaching one half the maximum is generated among the echo heights HB obtained until the movement in the direction X stops. The range DELTAX is set somewhere between the penetration tip position P1 from which the echo height reaches the peak to the point P1' at which the echo height reaches one half the maximum thereof HBM after it lowers from the peak point. Therefore, the point at which the echo height reaches one half the maximum thereof is only P1 in the range DELTAX thereby eliminating the detection of any wrong position.

Abstract: PURPOSE:To satisfy all conditions of a contact point by providing a fixed contact point with a first and a second auxiliary fixed contact points and allocating some needed condition of a contact point to the first and second auxiliary fixed contact points. CONSTITUTION:When a movable contact point 12 is separated from a fixed contact point 11, arc is produced across both the contact points 11 and 12. When the movable contact point 12 is transferred and a distance L of electrode separation between the movable and fixed contact points 12 and 11 is made larger to be longer than 1 if the movable contact point 12 is lowered. Thus, insulation is broken down between a first and a second auxiliary fixed contact points 13 and 14 to produce a short arc 17B thereacross and a long arc 17A is extinguished. The short arc 17B is extinguished at a zero point of an alternating current and the current is cut off. The first and second auxiliary fixed contact points 13 and 14 are provided to be allocated with some needed condition of a contact point. Therefore, there is no need to require all conditions of a contact point to the fixed and movable contact points 11 and 12 so that it is easy to satisfy the condition of the contact point.
