Title: Lead frame
Inventor: SUETAKE KENJI
IPC: H01L23/50
Filed: 1990-11-02
Abstract: PURPOSE:To increase in a tape adhesive strength, prevent a resin tape from separating by a pressure at the time of resin sealing, and contrive to reduce short circuit accidents of an inner lead by a method wherein unevenness is provided on a lead frame surface of a portion for adhering a resin tape. CONSTITUTION:A surface of an inner lead 2 and a hanging lead 3 of a lead frame having the inner lead 2 provided so as to be arranged round an island 1 and a hanging lead 3 for supporting the island 1 is selectively etched, alternatively unevenness is provided on a surface by coining and a resin tape 4 for fixing each other between the inner leads 2 is adhered. Here, an adhesive strength of the resin tape 4 can be strengthened due to the unevenness provided in the inner lead 2 and the hanging lead 3. Thus, there are not caused any problems in which the resin tape is separated from the inner lead at the time of mould resin sealing and the inner lead is deformed by a pressure of sealing resins, and short-circuiting occurs by contact between the adjacent inner leads.

Filed: 1989-11-17
Abstract: PURPOSE:To eliminate the trouble to remove the cap at the time of the concrete constriction jointing by forming the sheltering sheet for the cap and the holding part with one metal sheet. CONSTITUTION:By supporting the central part 1a of the blank metal sheet with the upper end of the lower die 3 and bending the range 1b, 1c to be the cap holding part 5 along the lower die 3 with the upper die 2, the holding part 5 is directed downward to the central part of the sheltering sheet. The means to give the bent range the function to hold the cap is the optional method that the reinforcing bar can be made to enter into the space of the downward directing part made to round or that the steel wire is attached and is wound to the reinforcing bar, etc. The range 1b, 1c to be the holding part 5 is bent and so the lacked part adjacent to the central part of the sheltering sheet is generated, so the reinforcing bar for the concrete construction jointing is inserted and bound itself along the preceding reinforcing bar and so the reinforcing bar can be jointed in attaching the cap as it is.

Filed: 1987-11-27
Abstract: PURPOSE:To detect the focusing state of a photographing lens by arranging a fine lens array around the expected image forming plane of the photographing lens, providing photodetectors on the optical path relay plane of some fine lens and making use of its output signal. CONSTITUTION:Fine lenses 40 of distributed index type are arranged closely to attain a plane, and the photodetectors 13a and 13b comprise a light receiving area 30 on the emitting plane of some lens in a group 7b. It is made shorter than a group 7a, and the photodetector forming plane 7c is placed closer to an object side than an image P1 formed by the photographing lens. The image is re-formed in a point P2 on the mat plane of a focus glass. Gratings 31a-31g are placed on the face 5a of a concave lens 5 to form a space filter. When sine movement is applied to the gratings, the output change of the photodetectors 13a and 13b is of reverse phase with front and back pins because fluxes incident on the photodetectors 13a and 13b have prescribed angles. Phase difference increases as the defocus of the photographing lens does. Therefore, the focus position of the photographing lens can be detected from the output of the photodetectors.

Filed: 1989-11-16
Abstract: PURPOSE:To suppress tape hiss by forming a ferromagnetic metal thin film layer on a substrate and specifying the forward and backward contact angles of water on the ferromagnetic metal thin film layer after a lubricant is applied thereon. CONSTITUTION:A lubricant is applied on the ferromagnetic metal thin film layer in a manner that the surface of the thin film layer shows >=100 deg. forward contact angle and >=60 deg. backward contact angle for water. Namely, wettability for water on the surface are determined by dropping water on the thin film layer to form 1 - 3mm water drop and measuring the height and diameter of the front and rear parts of the drop by magnifying on a monitor television. It is specified that the forward contact angle is >=100 deg. and the backward contact angle is >=60 deg.. When the thin film layer is made to have large forward and backward contact angles, affinity of the layer to a hydrophilic surface of an aluminum cylinder can be reduced and thereby, sticking of the thin film layer on the cylinder can be prevented. Thus, tape hiss can be suppressed.

Title: Muting circuit
Inventor: YOSHIDA SEIJI
IPC: H04B1/10
Filed: 1988-11-28
Abstract: PURPOSE:To eliminate the DC fluctuation of the muting circuit to constitute a muting circuit with fewer components by supplying a muting control current to a drive current source of the muting circuit. CONSTITUTION:When no muting is applied, a control current 12 does not flow. In this case, an input signal VIN is outputted to an output terminal Vout through a differential amplifier. When the control current 12 starts flowing, the drive current of the circuit is decreased by the flowed current, the gain is decreased and the output level is decreased. Since the output DC potential depends on a bias power supply V1, no output DC fluctuation takes place. Moreover, since the muting control current is used without being converted into a voltage, the circuit is realized with fewer number of components than that of a conventional circuit.
