Title: Audio signal recording and reproduction system
Inventor: HIROTA AKIRA
IPC: G11B20/00
Filed: 1980-11-04
Abstract: PURPOSE:To obtain high S/N ratio even at a low speed, by time-compressing an audio signal of a single rotating head system and performing multiplex- recording throulgh frequency division, restoring it to the original pitch through time expansion at reproduction and making it a consecutive signal. CONSTITUTION:In a single rotating head system, for example, video signals of NTSC are recorded on a video track 2a as every one field as luminance signal III of low carrier modulation and as low frequency carrier chrominance signal IV, and compressed audio signals are recorded as mixing and multiplex as V or VI at upper and lower bands. Two charge transfer elements (BBD) which are alternately read out and written in are used, the audio signal in time compression is multiplex-recorded, and the two read in the same audio through overlapping for the switching period of track. At playback, the time is expanded and the original audio pitch is restored and reproduced as a consecutive audio signal. Thus, the audio signal with good frequency characteristics and low noise are obtained even at a low running speed.

Title: Water ink
Inventor: IWATA KAZUO
IPC: C09D11/00
Filed: 1981-09-30
Abstract: PURPOSE:To provide water ink which scarcely causes bronzing even in the form of dye ink having an increased concentration and gives handwriting having a good density, consisting of a water-soluble dye, a water-soluble org. solvent, water and oxalic acid and/or an oxalate salt. CONSTITUTION:Water ink consists of a water-soluble dye such as C.I. Direct Black, a water-soluble org. solvent such as ethanol, water and oxalic acid and/ or an oxalate salt such as sodium oxalate. As compared with dye ink, pigment ink gives handwriting having a good density and hence is used as drawing ink, designing ink, etc. However, pigment is liable to agglomerate with time, so that it is necessary to disassemble writing utensils and to wash them. When the concn. of dye ink is increased, bronzing is liable to occur whereby handwriting reflects light and emits yellow to red light, and as a result there is a difficulty in reading it. By adding oxalic acid or an oxalate salt, the bronzing can be prevented and the necessity of disassembling and washing the writing utensils can be eliminated unlike the use of pigment ink.

Inventor: KURIOKA HITOSHI
IPC: F24F7/06
Filed: 1992-06-15
Abstract: PURPOSE:To ensure the prevention of expansion of smoke and the safety of a refuge path by a method wherein a high temperature gas is blown into a large space from a specified height when a fire occurs and the air in the large space is discharged at a part where no interference occurs with the blowing of the gas to allow the controlling of an internal temperature distribution and the selecting of the position of an air supply/exhaust port. CONSTITUTION:When a fire occurs at a fire outbreak part 17 in a large space indoors 7, a high temperature gas is blown in at a position with a specified height H1. As a result, a temperature boundary is formed at the position with the height H1. So, a bloom 20 will not rise across the boundary and a smoke layer 26 is formed at a position below the height H1. Even if there is a slight rise in temperature at a part above the height H1, none of the bloom, namely, smoke enters thereby securing the safety in refuge. In other words, the smoke, stays substantially at the position with the height H1, and when a refuge path leading to refuge passages from upper floors is provided above the position where the smoke stays, it is free completely from effect of the smoke.

Title: Delay time difference correction device for space diversity
Inventor: SONODA HIDEAKI
IPC: H04B7/08
Filed: 1994-06-15
Abstract: PURPOSE:To correct the transmission delay time differences caused among plural diversity branches by the difference of lengths of RF feeders without using any correction feeder for a fading circuit which uses a space diversity antenna. CONSTITUTION:A feeder correction circuit 110-1 uses the tap coefficient that is acquired when a delay time difference is corrected by an AMF(adaptive matching filter) 101-1. Then the circuit 110-1 applies the detection (115a-115c) to the acquired tap coefficient and decides the maximum value of the tap coefficient (116a-116c). Meanwhile plural routes (R-1, R0 and R+1) are set so that the different delayed variables are secured for the received signals. The route corresponding to the maximum value of the tap coefficient is selected and the received signals are transmitted through this selected route. Then the transmission delay time differences are eliminated among feeders by the transmission delays of those received signals.
