Title: Recycle packaging container
Inventor: KAWARAI HIROAKI
IPC: B65D5/56
Filed: 1992-11-30
Abstract: PURPOSE:To save the manhour for cutting and attaching foamed polystyrene for every product, reduce the cost and carryout packaging of many sorts of products by attaching bag-like objects, in which air can be sealed, on the inside of a packaging box. CONSTITUTION:A sheet-like bag 1 made of a material which is rather hard to break, such as polystyrene resin, nylon, etc., are attached on the inside of a packaging container. The bag 1 consists of several independent air chambers 1a, 1b, 1c... and check valves 2a, 2b, 2c... are provided between the air chambers. As air is allowed to flow only in one direction shown by arrows, air first enters the air chamber on the left side and flows toward the right side ones in turn by the pressure of air. When a valve 3 on the rightmost side is closed, air is kept from escaping. To release air, the valve 3 on the rightmost side is opened and the bag 1 is pressed from above so that the bag 1 is turned into a sheet-like shape. The reason the bag 1 is divided into sections is to prevent a decline in cushioning function of the bag 1 in the case of rupture of the bag 1. As to a packaging container used for transporting precision equipment which are apt to be easily damaged by a collision, an air feed port and an air discharge port are located inside the container.

Title: Fm multiplex broadcast receiver
Inventor: NAKAJIMA YASUO
IPC: H04B1/16
Filed: 1994-12-22
Abstract: PURPOSE: To utilize information from a VICS effectively by using a multiplex broadcast decoder to decode data into original signal data and displaying the decoded data onto a display device thereby reducing a channel selection time. CONSTITUTION: A tuner 2 selects a required channel and an audio signal separated from a broadcast signal is inputted to a speaker 5, from which the audio signal is reproduced. Furthermore, the broadcast wave signal is demodulated by an FM multiplex broadcast demodulator 6 and the signal demodulated by a multiplex broadcast decoder 7 is decoded into original data signal. When a reception level from the tuner 5 is low, an arithmetic unit 8 calculates an electric field strength from the broadcast station broadcasting the same content to a position of its own vehicle to allow the tuner 2 to select a broadcast station with a highest electric field strength. In this case, the unit 8 uses a memory 9 and stores data in the case of calculation. Then the signal decoded by the decoder 7 is displayed on a display device 1.  Then it is not required to search all stations in a broadcast list listing up the same content programs and the position of its own vehicle is grasped and the object broadcast station is selected through the calculation.

Abstract: PROBLEM TO BE SOLVED: To improve substantial recording and reproducing rates when data of a small size is intermittently transferred from an external apparatus to a recording and reproducing apparatus by effectively utilizing a buffer memory in the recording and reproducing apparatus. SOLUTION: A transfer data from an external apparatus is temporally stored in a buffer memory 18.
