Title: Die-bonding method
Inventor: KOSUGI KATSUMASA
IPC: H01L21/50
Filed: 1990-03-14
Abstract: PURPOSE:To control the thickness of a conductive paste and to suppress a warp at a curing operation after a die-bonding operation by a method wherein the die-bonding operation is executed by arbitrarily setting the distance between the surface of a lead frame and the rear surface of a semiconductor element. CONSTITUTION:In a die-bonding method to bond a semiconductor element 2 onto a lead frame 4 by using a conductive paste 3, a bonding operation is executed by arbitrarily setting the distance T between the surface of the lead frame 4 and the rear surface of the semiconductor element 2. For example, a collet 1 is moved onto an island 4 coated with a conductive paste 3 in a state that a semiconductor element 2 has been picked up at a low load. Then, the setting load of a bonding-load variable unit is changed over and is made sufficiently heavy; an up-and-down motion unit is lowered down to a previously set height in such a way that the gap between the island 4 and the semiconductor element 2 becomes T; and after that, a scrubbing operation is executed by using an X-Y movement unit. Then, when the collet 1 is raised, a die-bonded product whose paste thickness is T is completed.

Title: Tape reel
Inventor: SHIBAZAKI OSAMU
IPC: G11B23/087
Filed: 1991-03-27
Abstract: PURPOSE:To prevent recording and reproducing characteristics from deteriorating by resolving the difference in the surface level generated between the tape winding surface of a clamping member and the tape winding surface at the hub side so that the clamping member is pressed in the recessed part by the pressure of the tape. CONSTITUTION:When a magnetic tape 3 is not wound, a tape winding surface 14a of a clamping member 14 is kept protruded from the virtual tape winding surface extended from the outer circumference of a hub main body part 13b. To the contrary, when the tape 3 is wound around a tape winding surface 13a, the clamping member 14 is pressed in a recessed part 13c by the tape pressure and the winding surface 14a is levelled with a virtual tape winding surface F on the same circumference. Thus, since the difference in the surface level between the tape winding surface of the clamping member and that at the hub side can be resolved, the occurrence of the misalignment of the magnetic layers can be prevented and dropping-out can be prevented.

IPC: F25C1/24
Filed: 1994-03-31
Abstract: PURPOSE:To prevent a decrease in ice produced in an icemaking vessel by temporarily stopping switching operation of a tank valve mechanism and a water discharge valve mechanism when removal of a water storage tank is detected by tank detecting means. CONSTITUTION:When a user removes, a water storage tank 38, after a tank valve mechanism 41 is closed and a water discharge valve mechanism 30 is further opened after the mechanism 41 is opened, a water discharge valve open flag is set to '1'.

Thus, a valve drive motor is deenergized and stopped, and switching operation of the mechanism 30 and the mechanism 41 is temporarily stopped. In this manner, the operation for supplying a small amount of water stored in a constant quantity water storage tank 29 into an icemaking vessel 22 is eliminated. Thus, reduction in ice generated in the vessel 22 can be prevented.
