Title: Sound image localization control method
Inventor: NAKAYAMA MASAHIRO
IPC: H04R1/40
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To improve sound quality by correcting the discrepancy in transmission characteristics, which are made different for each person, from a target localized position and a speaker to the head. SOLUTION: The head transmission functions (HRTF) from the speaker set and arranged for practical measurement and from respective target localized positions to the human head or the dummy human head are respectively found (steps 101 and 102) and among these HRTF, move averaging processing is performed to the HRTF provided from the speaker on frequency amplitude characteristics (step 103). Based on this move averaged HRTF and the HRTF provided from the respective sound image localized positions, the transmission characteristics of a signal converting circuit are found and based on these transmission characteristics, coefficients for sound image localization are respectively calculated (step 105). By supplying these coefficients to the signal converting circuit at any suitable prescribed timing, the localization of sound image under inputting is controlled (step 107).

Title: Optical communication system
Inventor: TOMOFUJI HIROAKI
IPC: H04B10/572
Filed: 1990-11-22
Abstract: PURPOSE:To obtain a light communication system in which troubles such as deterioration of quenching ratio are hardly generated even at using a light amplifier in a saturated gain condition by using intensity modulated light of which sum of light intensity is nearly constant and wavelength is different. CONSTITUTION:It is provided with a signal light generating device 1 to generate intensity modulated light of which sum of light intensity is nearly constant and wavelength is different, a light transmitting passage 2 to transmit the intensity modulated light, and a single or a plurality of light amplifiers 3 provided on the signal light generating device 1 side of the passage 2 or on the way. The intensity modulated light transmitted through the passage 2 is separated in wavelength, and the separated intensity modulated light is converted from light to electricity. For example, a signal light A and a signal light B are mutually inverse and the amplitude are equal, as a result of this, the sum of intensity of both signal light A, B is nearly constant in elapsed time, and the light intensity input to the light amplifier 3 is constant in elapsed time. Hereby, even at using the light amplifier 3 in a saturated gain condition, troubles such as deterioration of quenching ratio and waveform are hardly generated.

Abstract: PURPOSE:To reduce a pressure loss and prevent an impingement noise of refrigerants from being caused at the time of the joining of the refrigerants by a method wherein the present device consists of refrigerant inflow ports provided at both ends of the device, a refrigerant joining part provided at the substantially central portion thereof and a refrigerant outflow port formed almost perpendicularly at the joining part, and a sectional area in the vicinity of the inlet part of the refrigerant outflow port is specified. CONSTITUTION:A refrigerant confluent device 11 is constituted of refrigerant inflow ports 13 provided at both ends of said device, with which refrigerant inflow tubes 12 are respectively connected, a refrigerant outflow port 15 provided at the substantially central portion of said device, to which a refrigerant outflow tube 14 is connected, an outlet expanded part 17 whose sectional area A is specified to 2/3S<= A<=S only in the inlet vicinity of the refrigerant outflow port 15 with respect to the sum total of the sectional areas of the refrigerant inflow ports 13, and a refrigerant joining part 16. The change of the flow direction of refrigerant gases joined together at the refrigerant joining part 16 of the refrigerant confluent device 11 is moderated at the outlet expanded part 17 in the vicinity of the inlet part of the refrigerant outflow port 15 because the sectional area of the outlet expanded part 17 is made larger than those of the refrigerant inflow ports 13, and, in addition, since a capacity is expanded at the refrigerant joining part 16, the occurrence of voltex that is caused by impingement of the refrigerant gases is reduced. Furthermore, the flow rate of the refrigerant gas after the joining is not instanteneously increased up to two times, so that a pressure loss of the refrigerants can be minimized, and an impingement noise of the refrigerants can also be hardly created.
