Patent JP-S57117179-A (JP)
Title: Signal transmission circuit
Inventor: KOISHI KEIJI
IPC: G11C11/41
Filed: 1981-01-08
Abstract: PURPOSE:To achieve input/output buses which makes read.modify.write in high speed, by discharging charges present on a signal transmission system by a transistor, before the introduction of a new state to the signal transmission. CONSTITUTION:When write-in operation is started with an external signal WE at time t11 and an internal signal phiw1 transits from a low to high level, input/ output buses IO, -IO are suppressed to a low level through MOSTQ11,Q12. Next, when the internal signal phiw1 transists from high to low level at time t12, the MOSTQ11,Q12 turn off. Next, write-in information is applied to the input/output buses IO, -IO at time t13. In this case, since the input/output bus IO is at low level, a MOSTQ02 to the gate of which the bus is connected turns off. Thus, the input/output bus -IO can be moved to high level in high speed. Thus, read. modify.write is made in high speed by input/output buses.

Abstract: PURPOSE:To provide a delay detection circuit capable of quickly and startly executing phase correction with high accuracy and superior an error rate. CONSTITUTION:A phase correction quantity estimation apparatus 5a which estimates phase correction quantity when a burst signal is received estimates a transmission symbol assuming that reception is performed by a known symbol string when it is recognized in advance that the known symbol with sufficient length of a preamble signal, etc., is transmitted asynchronously. Also. a phase correction quantity estimation apparatus 5b estimates a correct phase correction quantity from either the phase correction quantity in which phase difference is corrected by using a transmission symbole estimated by the phase correction quantity estimation apparatus 5a in advance or ideal phase difference from which a reception symbol estimated from the one in which the phase difference is corrected is to be outputted when the transmission symbol is unknown and also, it is impossible to estimate after a synchronous state is established. Thereby, a demodulation symbol signal 109 can be obtained by using a corrected phase signal 108 from which the influence of a frequency offset can be eliminated by a demodulator 8.

Title: Graphite crucible for metal vapor deposition
Inventor: MAEDA YOSHIHIRO
IPC: C23C14/24
Filed: 1991-01-14
Abstract: PURPOSE:To improve the durability of the graphite crucible for metal vapor deposition by specifying the physical properties of the graphite. CONSTITUTION:The ratio of the peak height I1 in the vicinity of the 3260cm<-1> band of the Raman scattering spectrum to the peak height I2 in the vicinity of the 1580cm<-1> band is controlled to <=1.0 with respect to the graphite which is used for the graphite crucible for metal vapor deposition. Consequently, the contact part between the molten metal and crucible is reduced, and the wettability between both materials is deteriorated. Accordingly, even if the graphite is porous, the molten metal is hardly infiltrated into the graphite, and the durability of the crucible is improved. Besides, the intercrystalline distance d in the X-ray analysis of the graphite is preferably controlled to 6.60 Angstrom  2d 6.80Angstrom , hence the reaction with the molten metal is hardly brought and the carbide formation of the graphite is mitigated.

IPC: B60H1/32
Filed: 1980-01-14
Abstract: PURPOSE:To increase the pressure of a refrigerant generated in a regenerator and enhance cooling power by a method wherein a mixed refrigerant liquid from an absorber is heated between the absorber and the regenerator by the heat supplied from a running engine. CONSTITUTION:The refrigerant evaporated in an evaporator 1 is absorbed in an absorbent liquid, and the mixed refrigerant liquid is heated while passing also through a cooling jacket 6a for the running engine 6 and then returns to the regenerator 7. Since the mixed refrigerant liquid is heated in the course of flowing to the regenerator 7, the quantity of heat is added to the quantity of heat deprived from exhaust gas in the regenerator 7. Accordingly, a sufficient amount of gaseous refrigerant is generated in the regenerator 7, with a high pressure. Since the evaporation amount in the evaporator 1 increases corresponding to the increase of the pressure of the refrigerant regenerated in the regenerator 7, the cooling power can be enhanced.
