Title: Production of mn-zn ferrite single crystal
Inventor: NAKAMURA EIJI
IPC: C30B29/22
Filed: 1990-05-11
Abstract: PURPOSE:To suppress contamination of Pt or Pt-Rh into a Mn-Zn ferrite single crystals by controlling flow rate of O2 introduced into a furnace when Mn-Zn ferrite raw materials are melted in a crucible made of Pt or Pt-Rh alloy and the single crystal is grown by Bridgeman method. CONSTITUTION:Mn-Zn ferrite raw materials such as Fe2CO3, MnCO3 and ZnO are charged and heated in a furnace made of Pt or Pt-Rh alloy to melt the raw materials. Then O2 is retained in a furnace in a definite time while introducing O2 into the furnace in a flow rate of 5-6ml/min based on 1cm<2> cross section of crucible. Then a Mn-Zn ferrite single crystal is grown by bridgeman method. Thereby the Mn-Zn ferrite single crystal reduced in contamination of Pt or Rh can be efficiently produced, because flow rate of O2 introduced is controlled and when the single crystal is applied to magnetic head, etc., high-performance product can be produced in good yield.

Abstract: PROBLEM TO BE SOLVED: To obtain a phthalocyanine composition which exhibits a high electrification potential, a high sensitivity and a stable performance by treating an amorphous phthalocyanine composition in a solvent containing water and an aromatic compound to convert the composition into a crystal form having peaks at specified Bragg angles in X-ray diffraction. SOLUTION: An amorphous phthalocyanine composition which contains a titanyloxyphthalocyanine and a nonmetallophthalocyanine is formed. This composition of 1 pt.wt. is subjected to crystal transition by dispersing it in 2-100 pts.wt. water, adding an aromatic compound (e.g. naphthalene) in an amount of 10-500 wt.% of the composition and an organic solvent (e.g. n-pentane) in an amount not larger than that of the aromatic compound to the dispersion and heating it under stirring. Thus treated composition exhibits peaks at Bragg angles (2θ±0.2 deg.) of 7.0 deg., 9.0 deg., 14.1 deg., 18.0 deg., 23.7 deg. and 27.3 deg. in X-ray diffraction with the CuKαemission line (1.541 Å), Phthalocyanines include titanyloxyphthalocyanines, nonmetallophthalocyanines, copper phthalocyanines, gallium phthalocyanines, or the like.

Title: Transmission control method
Inventor: MIYAO YASUHIRO
IPC: H04L1/16
Filed: 1988-05-18
Abstract: PURPOSE:To prevent a busy state from continuing permanently by deleting received data without an error just before the busy state is generated in case that the capacity of a reception buffer is insufficient for the maximum outstanding numbers, and securing one vacant reception buffer by the above deletion for the reception of re-transmission data. CONSTITUTION:When the capacity of the reception buffer is four and is insufficient for the maximum outstanding numbers 5, the last data I5 received without the error continuously until the busy state is generated is deleted after transmitting a selective deletion response SREJ1 when the busy state is generated in a state where the selective deletion response SREJ1 is transmitted and the waiting state of the re-transmission of data 11 is generated, and one buffer for the reception of the data 11 is secured. When the data 11 is received normally, since a reception side can process the data in sequence of I1, I2, I3, and I4, and release the buffers sequentially, it is possible to prevent the busy state at the reception side from continuing permanently.

Title: Semiconductor integrated circuit
Inventor: KOMATSU SADAHIRO
IPC: H03K19/013
Filed: 1992-04-15
Abstract: PURPOSE:To fix an emitter potential of a 3rd transistor(TR) to a prescribed value by forming an output stage by emitter coupling and applying an output used to convert a logic signal into a current output from the 3rd TR in cascade connection to a 2nd TR through wiring. CONSTITUTION:TRs Q21, Q22 are emitter-coupled and the sum of collector currents IC1, IC2 flowing to the TRs Q21, Q22 is kept constant to be a prescribed current I2. Thus, the collector circumferential IC2 flowing from an ECL circuit 22 to the TR Q22 via a wire 7 is increased/decreased in response to a difference voltage of the inverted output D2 with respect to a voltage source E1. An idling current I21 extracted by the constant current source 23 is always supplied to the cascade TR Q23 outputting a collector current to the ECL circuit 21 of the pre-stage, resulting in that the emitter potential of the TR 23 is made stable at nearly a constant voltage. As a result, while the increase in power consumption is suppressed, the delay time due to the effect of wiring capacitance C is reduced and even when the wiring is long, the circuit 21 drives a poststage circuit 22 at a high speed.

Abstract: PURPOSE:To enable a user to change properly data in a dial device having an abbreviated dialing function, by using an RAM which can rewrite the telephone number data of the remote side together with an ROM storing the prescribed telephone number data of the remote side. CONSTITUTION:A register region 1' for telephone number of remote side of an RAM1 has a storing region for said telephone number data to an address corresponding to the abbreviated dialing data. The data is stored in a register region 2' for telephone number of remote side of an ROM2 in response to a correspondence list between the abbreviated dialing data given previously from a user and the telephone number data of the remote side. When the abbreviated dialing data is supplied from a dial key pad, a control part 5 decides whether the data exists in the RAM1 or the ROM2. If the data exists in either one of the RAM1 and ROM2, the telephone number data of the remote side is read out of the corresponding memory and sent to a dial circuit (not shown in the diagram) via a bus 4.

Title: Radio wave anechoic chamber
Inventor: TSURUTA MAKOTO
IPC: H05K9/00
Filed: 1989-05-18
Abstract: PURPOSE:To prevent a reflected wave from arriving at a reception antenna by forming the walls of a radio wave anechoic chamber of a metal material, arranging many conical radio wave absorbers made of a radio wave absorption material inside at least one wall of a floor wall, four sidewalls and a ceiling wall, and providing random reflectors on the walls. CONSTITUTION:An electromagnetic wave oscillated from an oscillation source 18 is radiated radially in addition to a reception antenna 19, and arrives at radio wave absorbers 20. The wave is partly reflected on the surfaces of the absorbers 20, and residually transmitted therethrough. The waves which are transmitted through the absorbers 21 and arrived at random reflecting faces 23 of random reflectors 24 are not reflected perpendicularly toward a flat bottom 22 but mostly reflected in a state inclined toward the bottom 22. When the waves are inclined and reflected in this manner, the waves are not transmitted through a radio wave absorbing plate 22 disposed in the bottom but reflected here. The reflected wave is further reflected on the surfaces of the reflectors 23 to be gradually attenuated. Accordingly, the waves transmitted through the absorbers 20 are reflected on the wall 12, not returned to a radio wave anechoic chamber, but repeatedly reflected between the absorbers 20 and the absorbers 23 to be absorbed.
