Title: Carrier wave reproducing circuit
Inventor: YOSHIDA YASUHARU
IPC: H04L27/06
Filed: 1978-03-03
Abstract: PURPOSE: To reproduce the carrier wave of the orthogonal partial response modulation system by causing the small number of circuit element to perform stable leading-in at every π/4 and eliminating noise components.  
     CONSTITUTION: QPRS input signal S is subjected to envelop detection 5 and has AM components extracted, and signals a 1  to a 4  of amplitude β and signals b 1  to b 4  of amplitude γ are distinguished from each other in 6 and are π/4-phase-modulated by output G 1 . Simultaneously, when the amplitude is reduced to 1/12 1/2 , signals a 1  to a 2  agree with signals b 1  to b 4 , and AM components of the difference between β and γ are compensated to obtain signals like a 4 PSK wave. This wave is multiplied by four in 8 for the purpose of eliminating 4 PSK wave components and is subjected to phase comparison in 9 to obtain phase error signals. Then, when these signals have noise components eliminated through LPF 10 and are supplied to VCO 11, the reference carrier whose phase is synchronized with the input signal is obtained. Then, this carrier is given to detector 1 and is given to detector 2 after π/2 phase shift to detect signal S synchronously, and demodulated signals S 1  and S 2  are obtained. In this constitution, since π/4 phase modulation is performed in 4 by signal G 1  which is directly detected from the input signal, a leading-in stable point exists only at every π/4.

Title: Address conversion buffer control system
Inventor: HIRAIWA ATSUSHI
IPC: G06F12/10
Filed: 1992-01-14
Abstract: PURPOSE:To clear an address conversion buffer without making a following request wait. CONSTITUTION:Valid information in a buffer 12 outputs a corresponding physical address from an entry in a valid state corresponding to the input of a logical address. A flag indicating whether or not a valid word is present in a corresponding group is held in a table 15 corresponding to a group constituted of plural entries in the buffer 12. The flag of the table 15 is invalidated in response to a clear command. At the time of an access to the buffer 12, when the flag of the group in which the word of the access object is included is invalid, the logical address is converted into a physical address, and the valid information of the entire entries of the group corresponding to the invalid flag is turned to the invalid state during the pertinent converting processing.

IPC: H01L21/312
Filed: 1986-02-06
Abstract: PURPOSE:To enable a protection layer to be formed with a sufficient thickness even on edges of a semiconductor piece, by applying a polyimide precursor having a specific concentration of non-volatile matters on the surface of the semiconductor piece and setting up it to form the protection layer. CONSTITUTION:A semiconductor element has a square semiconductor piece 1 joined thereto with a protection film 5 provided therebetween for protecting the exposed and joined surface of the semiconductor piece. A polyimide precursor containing 25% or more non-volatile matter is dropped onto and applied on the surface of the semiconductor piece 1 and heated. When the solvent in the polyimide precursor has been evaporated and the precursor is set up, a protection layer can be obtained, with a thickness of 40mum or more on the flat section. Thus, only one application can provide a protection layer 5 having a sufficient thickness even on the edges 10 of the semiconductor piece 1 as shown in the figure. The concentration of the non-volatile matter is desirable 25-80%, since it becomes difficult to apply the polyimide precursor if it exceeds 80%.
