Title: Tape cleaner in tape loading device
Inventor: HASHIMOTO KEISUKE
IPC: G11B23/50
Filed: 1994-04-05
Abstract: PURPOSE:To facilitate stable tape traveling. CONSTITUTION:A blade 32 is positioned in such a position that a tape contacting end of a blade edge 32a is brought into contact with a tape recording surface T1 by intersecting the tape width direction. Consequently, since a part of a tape joint (c) and a part of the blade edge 32a are brought into contact with each other when the Joint (c) of the magnetic tape T passes the blade 32, the blade 32 does not face a gap (g) of the tape joint (c) like the conventional case, and hence the blade 32 can be prevented from being caught in the position of the tape joint.

Title: Gust and flank wind-proof container chassis for marine container transportation
Inventor: AOSHIMA HIROMICHI
IPC: B60P3/40
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a container chassis scaleable of performing stable tangling against gust or flank wind for transporting two 20-feet marine containers at the same time. SOLUTION: A container chassis longer than a conventional container chassis is manufactured, space of about 90 cm to 100 cm is formed between front and rear containers and these containers are fixed to the container chassis. Thus, new vector backward in an advancing direction for receiving wind to the front face of the rear container is generated. On the other hand, when flank wind passes between the front and rear containers, a new vortex flow 4 is generated to counter this flank wind. These two types of effect can cope with the degradation in operability caused by wind, which is the weakness of a tractive type transportation.

Abstract: PURPOSE:To reduce combustion noise, by providing a detector means for detecting the state of slow gears in the high-load rapid running region of an engine and by using the detection output of the means to delay the time of ignition. CONSTITUTION:A gear switch 11 is closed when gears are rotating slowly. A negative intake pressure switch 12 is closed when a diaphragm 16 is moved leftward due to the weakening of negative pressure in an intake pipe 15 under high load. The switches 11, 12, 13 are all closed only when a transmission 14 is in a slow state and the negative intake pressure is strong and the revolution speed of an engine is rapidly rotating at a speed not lower than a prescribed level. when a relay 10 is energized and a switch 9 is closed, a contact 8 is grounded. In that case, the contact 8 remains closed even if another contact 7 is opened sooner by the rotation of a cam 6. For that reason, the time of ignition of a spark plug 1 is put in the delay region to make the rising of combustion unsharp enough to reduce the combustion noise.
