Title: Audio signal comparing circuit
Inventor: WATABE FUMIO
IPC: G01R29/00
Filed: 1983-06-17
Abstract: PURPOSE:To determine the identity of two audio signals at a sufficient accuracy with a simple construction by comparing and determining results of the comparison of delayed voltages for detecting the rising and falling of signal waveforms. CONSTITUTION:When a need arises to match the audio signal in the polarity as inputted from the terminal B, the audio signal inputted from the terminal A is inverted with a voice signal inversion circuit 1 and processed with a DELTAt delay voltage comparator 3 which compares the signal with the other input thereof delayed by the time DELTAt through a capacitor or the like by way of an LPF2. The audio signal inputted from the terminal B is likewise processed with an LPF4 and a DELTAt delay voltage comparator 5. The comparison pulses corresponding to the rising and the falling of a waveform based on variations with the time DELTAt of the respective audio signals from the comparators 3 and 5 are compared with a voltage comparator 6 and when both the signals coincide, the output of the comparator 6 becomes zero. Thus, with a simple construction, the identity of the audio signals is determined at a sufficient accuracy with a stable comparison depending on the rising and the falling of the waveform.

Title: Structure of seal ring groove
Inventor: TANIGUCHI KUNIHARU
IPC: F16J15/06
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To easily remove both members by reducing or eliminating frictional resistance force in a contact surface of a seal ring and the members generated at removing time of both members by forming a function for changing compressibility of the seal ring in a seal ring groove. SOLUTION: A seal ring groove 3 is formed of a shallow groove part 5 and a deep groove part 6. When pulling out a first member 1 fitted with a seal ring 4 from a second member 2, the seal ring 4 moves to the deep groove part 6 from the shallow groove part 5 by frictional resistance force caused by contact with an inside surface of the second member 2. Thus, the seal ring 4 after finishing a movement to the deep geoove part 6 reduces compression or eliminates the compression between both members. Thus, the frictional resistance force caused by the contact of the seal ring 4 and the inside surface of the second member 2 is reduced or eliminated, so that both members can be removed with small force.

IPC: B29C48/00
Filed: 1984-05-30
Abstract: PURPOSE:To suppress the heat shrinkage of a core material layer and to obtain excellent optical transmission characteristics even at high temperatures by optimizing the ratio of the sectional area of a protection layer and the total sectional area of the core material layer and a sheath material layer. CONSTITUTION:The plastic transmissive fiber consists of the core material layer 1, sheath material layer 2, and protection layer 3 as a basic constitution unit, and the sectional area of the protection layer 3 is >=0.78 times the total sectional area of the core material layer and sheath material layer.
