Filed: 1989-12-14
Abstract: PURPOSE:To enable constant voltage control without increasing the capacity of a saturable reactor even when the output current is low by superposing DC voltages to be controlled and not controlled and producing a DC output voltage. CONSTITUTION:Switching means Q1, Q2 repeat ON/OFF operation alternately to apply a DC input voltage onto each half winding of a primary winding T1 thus inducing square voltages V31, V41 in the secondary winding T2 of a transformer T.

Title: Container for transporting live fish
Inventor: TAKASUGI MITSUO
IPC: A01K63/04
Filed: 1989-12-13
Abstract: PURPOSE:To reduce the mortality ratio of live fishes during transportation to an extremely low value by providing the upper part of a water tank with an overflow port and simultaneously installing an overflow valve below the aforementioned overflow port, keeping circulation of water and enabling feed of air in the form of a curtain. CONSTITUTION:When some case housing containers 33 are taken outer a water tank 1 in the course of transportation, the water level is lowered to attain the water surface below the upper overflow port 7. Thereby, an overflow valve 8 located below the overflow port can be opened to overflow water at a lower position and keep circulation of water. Since air is blown from slender rodlike air stones in the form of a curtain without directly touching the fishes, the mortality ratio during transportation thereof can be reduced to an extremely low value. Furthermore, water temperature in the water tank is kept in a prescribed low temperature state capable of checking movement of the fishes to enable housing and transporting of the live fishes at a high density.

Title: Decoding of compressed data
Inventor: MAIKERU EMAARITSUCHI NAAJII
IPC: H03M7/46
Filed: 1990-11-28
Abstract: PURPOSE: To decode compressed data by issuing a literal reference when a first bit is '0' and a hysteresis reference (lexicon reference) when a second bit is '0' ('1') and the first bit is '1'. CONSTITUTION: When a first bit is '0', the first reference becomes a literal reference and the next eight bits become literal symbols. When the first bit is '1', the first reference becomes a hysteresis reference of lexicon reference and the true nature of the reference is made clear by a second bit. When the second bit is '0', its reference becomes a hysteresis reference and the offset value of a hysteresis buffer and the length value of a hysteresis reference follow the hysteresis reference. When the second bit is '1', its reference becomes a lexicon reference and a lexicon index value follows the lexicon reference. Therefore, a compressed bit stream can be constituted to literal, hysteresis, and lexicon reference sequences in a restorable state by analyzing the bit stream.
