Title: Phase control circuit
Inventor: OKAWA TAKEHIRO
IPC: H03H11/16
Filed: 1989-07-19
Abstract: PURPOSE:To eliminate the need for setting a phase angle at every change in the frequency by adding a circuit switching the input to a circuit controlling one or both sinusoidal wave and cosine wave components of an input signal and adding them to control the phase. CONSTITUTION:A sinusoidal wave and a cosine wave component with equal amplitude are respectively inputted to input terminals 1, 2. A sinusoidal wave passes through a signal changeover switch 3 as one input to an adder 4 and a cosine wave passes through the signal changeover switch 3 as one input to a multiplier 5. A DC voltage of a prescribed range enters the other input of the multiplier 5 from a control input terminal 6 as a phase angle setting signal. Then the cosine wave subject to amplitude control with, e.g. a multiple of 0-1 by the multiplier is the other input of the adder 4. The output of the adder 4 subject to lead phase control by 0-45 deg. with respect to the sinusoidal wave is inputted to a numerator term of a divider 8 and an output of a function generator 7 receiving the DC voltage of the input terminal 6 connects to the denominator term. As a result, a waveform signal subject to phase control and amplitude control equal to the case with the input signal is outputted from an output terminal 9 connecting to the output of the divider 8.

IPC: H01L23/28
Filed: 1983-10-03
Abstract: PURPOSE:To obstruct trouble resulting from the large thermal expansion of a buffering agent, to reduce the deterioration of an element and to improve reliability by forming the curved section of an upper electrode body and forming a hole closed by the buffering agent to the upper electrode body. CONSTITUTION:An upper electrode conductor 5 has a hole 9 opened toward a lower section in a vertical section 54 besides a curved section 53 having flexibility. The end of the curved section 53 forms a contact section 55. The contact section 55 is brazed to the upper surface of a semiconductor chip 4, and a buffering agent 8 is applied and cured so as to cover both the chip and the hole 9. The whole is wired, and lastly sealed by a casting material 7. Since a cavity section 9 coexists, stress by the buffering agent 8 is reduced because the expanded volume section of the buffering agent 8 is absrbed to the cavity section 9 on the temperature rise of a temperature cycle. Accordingly, stress sigma1 is absorbed by the buffering agent 8, sigma2 by the curved section 53 easy to be varied and the stress sigma3 of the buffering agent by the cavity section 9 severally approximately.

Title: Digital signature system
Inventor: NISHIOKA TAKESHI
IPC: G09C1/00
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To prove the genuineness of a public key by applying unidirectional homorphoic image dependent on a signed message and a signer ID to the secret algorithm which is previously distributed to every entity and using the algorithm to be newly generated as the signature information. SOLUTION: A center generates a center algorithm that is known only by the center and then generates a secret algorithm A3 that is inherent to an entity from every center algorithm and the entity ID. The algorithm A3 is distributed to every entity by a method whose safety is assured. The entity which acquires the algorithm A3 inputs the ID of an opposite party of communication to every algorithm A3 to easily share a common key corresponding to every center algorithm. Thus, an optional authentication requester can authenticate the signature by using the algorithm A3 that is used for sharing a key and without performing any preliminary communication with the signer.
