Title: Clothes drying machine
Inventor: MATSUI HIROARI
IPC: D06F58/04
Filed: 1990-06-01
Abstract: PURPOSE:To prevent dew condensation on inner walls of the body by mans of improved cooling of parts within the body, by providing a louver to a part of a fan case cover where an exhaust duct is formed, providing an opening at the downstream end of cooling air in the louver and connecting the exhaust duct within the body at the position of the opening. CONSTITUTION:There occurs an exhaust stream A between a fan case 7 and a fan case cover 15 due to rotation of a heat-exchange type fan 6. This exhaust stream A enters a body 1 through an exhaust introduction inlet of the fan case 7, to cool a motor 11 control parts, etc., of which temperatures rise during operation. The exhaust stream B flows through a cooling exhaust outlet 19 of the fan case cover 15, passes through an exhaust duct 18 of a rear plate 8 and then flows out of the machine through an exhaust outlet 10. The exhaust stream A always discharges into the tightly closed body 1. Though pressurized by the heat-exchange type fan 6, the stream hardly flows. Accordingly, when a large quantity of exhaust stream B passes through the duct 18, the pressure of the opening portion 20 at the lower end of the louver 21 becomes so negative that the exhaust A is sucked into the duct 18.

Title: Electronic device
Inventor: FUKUMOTO TAKUYA
IPC: H01L21/60
Filed: 1986-06-23
Abstract: PURPOSE:To improve the bondability of both a pad formed on a semiconductor chip and inner leads and the moisture resistance thereof by intermittently forming contracted parts of cross sections by slits, waveforms, or cutouts at tab hanging leads to increase a resistance with respect to moisture at the contracted parts, and enlarging the part integral with the sealer. CONSTITUTION:Three slits 5 are formed at tab hanging leads 4. Since the slits are formed at a predetermined interval, cross sectional contracted parts ate intermittently formed at the leads 4. The pads formed at a semiconductor chip 3 are bonded to inner leads 7 by Au wirings or aluminum wirings to form an IC 1. Since the moisture transmitting route is reduced at the contracted part, it increases a resistance against moisture, thereby reducing the invasion of moisture. A sealer 6 is strengthened in its integration through the leads 4. Since the slits 5 are intermittently formed, the whole leads 4 have elasticity. Even if thermal stress is applied to the leads 4, they can absorb it.
