摘要:
An electronic apparatus has a substantially rectangular box-like housing, having a top wall. A storing section is formed in the housing adjacent to the top wall of the housing and having an insertion opening in the housing. A card-like electronic member is detachably insertable into the storing section through the insertion opening in a card inserting direction. A plate like ejecting member is attached to an under side of the top wall of the housing and located above the storing section in the housing so as to be slidable in a direction parallel to the direction in which the electronic member is inserted into the storing section. An operation member on the ejecting member projects outside the housing through an opening formed in the top wall of the housing. A pressing claw on the ejecting member abuts against an inner inserted end of the electronic member when the electronic member is inserted into the storing section, and the pressing claw pushes the electronic member outside the housing, through the insertion opening, when the ejecting member is moved toward the insertion opening.

A pattern discriminating apparatus with an interval integrating section for integrating detection signals from a detecting section for each of a number of intervals of a bill. A bill is supplied to the detecting section which detects, for example, a magnetism pattern of the bill. The detection signal from the detecting section is supplied to the interval integrating section as well as to a total integrating section. The total integrating section integrates the detection signals for one bill. The signals from the interval integrating section are temporarily stored in a memory section, are supplied to a smoothing section, and are smoothed thereby. The smoothed signal is supplied to normalizing section to be normalized based on the signal supplied from the total integrating section. The normalized signal and a signal output from a pattern memory section are supplied to a subtracting section for taking the difference between these two signals for each of the intervals. The difference signal thus obtained from the subtracting section is integrated in a difference integrating section for each interval and is then supplied to a discriminating section. Based on the signal from the difference integrating section, the discriminating section discriminates the authenticity, denomination and top or bottom surface of the bill.

An enclosed-type magnetic disc recording and/or reproducing apparatus according to this invention, having a pressure chamber to enclose a bearing unit of a flange rotating along with a magnetic disc, introduces an air pressure at a high-pressure portion, created by an air flow produced by rotation of the magnetic disc and the flange, into the pressure chamber so as to raise the pressure within the pressure chamber to a level higher than 1 atm., thereby preventing the lubricant evaporated from the bearing member from sticking to the magnetic disc or head to lower the faculty thereof.

A reverse conducting thyristor includes a thyristor section, a diode section and a semiconductor separator section for electrically separating both the sections. The thyristor section includes: a first region of first conductivity type, a second region of a second conductivity type, a third region of the first conductivity type, a main emitter region of the second conductivity type, an auxiliary emitter region formed, with intervention of the exposed portion of said third region, facing at least a part of the periphery of said main emitter region which does not contact the separate section and a cathode electrode, an auxiliary gate electrode contacting the auxiliary emitter region and enclosing, with intervention of the exposed portion of the third region, at least a part of the periphery of said main emitter region which does not contact the separate section, and a main gate electrode formed on the exposure surface of the third region contacting the side wall of the auxiliary emitter region which does not face the main emitter region. The respective components are successively layered on a first electrode acting as an anode electrode. The diode section includes a fourth region of the second conductivity type formed on the first or anode electrode, a fifth region of the first conductivity type formed on the fourth region, and a second electrode formed on the fifth region and connected to the cathode electrode. The separate section includes a sixth region formed on the first electrode and of the first conductivity type, a seventh region formed on the sixth region and of the second conductivity type and an eighth region formed on the seventh region and of the first conductivity type. The resistance values of the semiconductor layers between the cathode electrode and the second electrode and between the cathode electrode and the auxiliary gate electrode are each 2 to 18 Ohms.

With a packaged semiconductor device of this invention, an IC pellet or chip supported on a mounting unit is encapsulated in plastics material, for example, epoxy resin or silicone resin. A plurality of lead strips are disposed at one end in the proximity of the mounting part of the mounting unit. The lead strips are electrically connected to the respective conductive pads of the IC pellet set on the mounting part of the mounting unit. The lead strips extend at the other end outside of an plastics material. Mounting unit-reinforcing side walls project substantially at right angles from the edges of the flat part of the mounting unit. The heat-radiating legs of the mounting unit extend substantially at right angles from the low edges of the side walls with the bottom surface of said legs exposed to the outside of the plastics material.
