Title: Bonding material and its manufacture, and semiconductor device
Inventor: OKUTOMI ISAO
IPC: H01L21/52
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent semiconductor chips from being broke and to reduce a failure caused by an insufficient cooling capacity, by making the heights of the laminated members uniform by adjusting the thickness of a bonding layer even if semiconductor chips or the other constituents constituting a device are different in height from each other. SOLUTION: A bonding material 6 is made of a composite material of a metal having a low melting point and a porous metal, and thus is not made completely fluid at a bonding temperature but is compositely changed by a small stress and has high wettability. Even if Si chips are different in height from each other when the top portions of the Si chips are pressed by an upper die, the bonding material 6 is compositely changed to align the heights of the Si chips with the height of the side wall of the lower die. This can align the heights of the Si chips and, when the Si chips are press-bonded to a water-cooled heat sink, this can prevent a force from being concentrated at a specified point and prevent the built-in Si chips from being broke and apply a sufficient pressing force thereto, which results in producing sufficient cooling performance.

Title: Filter available for selective variation in frequency characteristic
Inventor: UENO NORIO
IPC: H03H11/04
Filed: 1978-12-19
Abstract: PURPOSE:To vary frequency characteristics by selectively connecting auxiliary capacitor by exercising control over switching element on a common substrate under external control. CONSTITUTION:In a filter where capacitors CA1-CA8 connected to a signal input terminal and earth terminal by switching are arranged and connected by switching at a fixed clock frequency, auxiliary capacitors CAS1-CAS8 are provided in parallel to respective capacitors and then connected via switches S1-S8. A capacitor with a small value among capacitors determining frequency characteristics is regarded as a main capacitor, and a difference among respective capacitors corresponding to respective characteristics is considered to be the value of an auxiliary capacitor. For example, switches employ MOSFETs and are controlled by applying a direct- current voltage to gate electrodes. In this constitution, extremely-easy and selective variation in frequency characteristics can be done and all elements are arranged on the common substrate, so that miniature and excellent characteristic filters can be mass-produced.

Filed: 1985-07-22
Abstract: PURPOSE:To prevent an engine and a drive system from being damaged due to abrupt change-over, by restraining a forward and backward travel change- over device, from being changed over when the speed of a vehicle not yet drops below a predetermined speed. CONSTITUTION:A forward and backward travel change-over limiting device 92 is provided with a stopper 94 and a ring 96 which are fitted no a rotary shaft 42. The stopper 94 is rotatably held on the rotary shaft 42, and is changeable between forward and backward travels by means of a spring 102 as a returning means. The ring 96 is engaged with the rotary shaft with a suitable frictional force, and is also engaged at its one end with the stopper 94. When the rotary shaft 42 is rotated, the ring 96 is dragged by the rotary shaft 42 due to the frictional force between itself and the latter and the viscosity of oil and therefore, the stopper is moved overcoming the bias force of the spring 102 to restrain the change over between forward and backward travels. When the speed of the rotary shaft 42 becomes lower by some degree, the stopper 94 returns by means of the bias force of the spring 102 to a position where it allows the change-over between forward and backward travels.
