Title: Dtmf signal receiver
Inventor: YAJIMA MASAHARU
IPC: H04M11/00
Filed: 1988-09-29
Abstract: PURPOSE:To prevent a disabled reception and a malfunction by outputting a tentative reception signal representing a request of remote control when a specific frequency is detected. CONSTITUTION:The output of a BPF 11 for specific frequency is inputted to a specific frequency power detection section 12, which sends a signal to a control section 13 when the input is larger than a threshold level. A control section 13 outputs a signal representing the reception of the DTMF signal by a low- order group from a control output terminal 15 when the signal is consecutive for a prescribed time. The output is used as a tentative reception signal for remote control request from an opposite party and the output excludes the noise element at the reception of the DTMF signal. Then a remote control DTMF signal is received to prevent the occurrence of the malfunction or the like even in the equipment of a comparatively simple signal identification means.

Title: Nonaqueous solvent secondary battery
Inventor: NOSE HIROYOSHI
IPC: H01M4/58
Filed: 1987-09-30
Abstract: PURPOSE:To prevent the deterioration of an electrolyte and short circuit caused by the growth of a dendrite by containing a reaction product of an active material with lithium so as to have a concentration gradient in a positive mix, and using a cabonized baking product of an organic material as a negative electrode. CONSTITUTION:A positive current collector 2 is bonded to the bottom of a container 1 which also serves as a positive terminal. A positive mix 3 using lithium and transition metal chalcogen compound as an active material is pressed against the current collector 2. The reaction product of active material with lithium is contained in the positive mix 3 so that its content is gradually increased toward the current collector 2 side. A negative electrode 4 comprising a carbonized baking product of an organic material is placed on the positive mix through a separator 5. The dissolution of lithium into an electrolyte in charge-discharge can be prevented. Most of the reaction product uniformly moves during charge-discharge from the side opposing to the separator 5 to the separator 5 side through the inside of the positive mix 5 by a barrier action, and ionized lithium thereby uniformly moves to the negative electrode. In addition, the dissolution of lithium into the electrolyte is prevented.

Title: Magnetic tape cassette and its manufacture
Inventor: SUZUKI OSAMU
IPC: G11B23/113
Filed: 1990-09-17
Abstract: PURPOSE:To improve the compression strength of a hub and to prevent the layer down of a tape by forming the hub by means of magnetic orientated liquid crystal polymer or a resin material including magnetic orientated liquid crystal polymer. CONSTITUTION:The hub is formed by magnetic oriented liquid crystal polymer which is molecule-orientated or the resin member including the polymer.
