Title: Magnetic head and its production
Inventor: KOUE HIDEAKI
IPC: G11B5/255
Filed: 1983-10-19
Abstract: PURPOSE:To improve the accuracy of track width and to facilitate the work of a magnetic head by forming a groove at the side part of a magnetic core in the tape sliding direction to prescribe the track width and filling a spacer made of a nonmagnetic substance into said groove. CONSTITUTION:Two rod-shaped matters 6 and 6 are made of a metallic magnetic substance such as ''Sendust'', etc. A window 5 is formed to one of matters 6, and both matters 6 are processed into a prescribed shape respectively. These processed matters 6 are adhered to each other by a glass welding process to obtain a block 7. In this case, the junction surface of both matters are opposed to each other with microgaps in-between. The fused glass is flowed into these gaps to form a head gap 2. Then many grooves 13 are formed by crossing the gap 2 with rubstones, etc. These grooves 13 divides the gap 2 with prescribed track width (t). In this case, the groove 13 can be processed with blocks 7 and rubstones positioned mechanically. Therefore the track width (t) can be contuolled to have extremely high accuracy of about + or -3mum.

Title: Control device for internal combustion engine
Inventor: MATSUMOTO MIKIO
IPC: F02D41/34
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To avoid adverse effect on purge operation for stratified operation by inhibiting the stratified operation under a condition in which the degree of generation of evaporated fuel is high, in order to carry out homogeneous operation. SOLUTION: A temperature FTEMP of fuel in a fuel tank is detected (B1) so as to determine whether the degree of generation of evaporated fuel is high so as to give adverse effect on purge operation for stratified operation or not (B2, B3, B4, B5). If the degree of generation of evaporated fuel is high so as to fear that adverse effect becomes higher, the stratified operation is inhibited but homogeneous operation (including both stoichiometric operation of lean operation) is carried for lowering the possibility of occurrence of such a fear (B6). With this arrangement, the capability of purge process is maintained by the homogeneous operation, thereby it is possible to avoid adverse affect on drivability, exhaust smoke or the like due to effect by purge gas caused when the purge operation is carried out while the stratified operation is carried out.

IPC: B65G15/64
Filed: 1986-08-21
Abstract: PURPOSE:To reduce the load of signal processing on a CPU by providing a controller which performs displacement correction control over a beltlike photosensitive body, and stops driving the photosensitive body and applies a signal to the CPU of the main copying machine when the displacement becomes abnormal. CONSTITUTION:For example, the beltlike photosensitive body is displaced and the 1st photoelectric element 22a detects an edge; and the Q output of a flip-flop 27 goes up to level 'Hi' and the Q output of a flip-flop 28 also rises to level 'Hi' associatively. In this case, the output of the 2nd photoelectric element 22b rises to 'Hi', and consequently a tracking motor M is driven with the output of an Ex-OR gate 29. When the tracking motor M is driven, a sector 17 also rotates and the photoelectric element 18 detects the state of a peripheral piece when the sector makes almost a half turn. Thus, the tracking motor M is brought under nearly a half turn control by the position detection of the photoelectric element 17.
