Title: Manufacture of transformer
Inventor: MURAI IWAO
IPC: H01F41/02
Filed: 1982-03-27
Abstract: PURPOSE:To improve the magnetic characteristics of a transformer and reduce noise and make it possible to construct it by robot or an automatic assembling device by forming concave and convex sections in opposing faces of a block of stacked steel plates of different sizes and inserting two blocks of stacked steel plates into a coil so as to make the concave and convex sections mate together. CONSTITUTION:A block 1 of stacked iron cores that is shaped an E shape and a block 2 of stacked iron cores that is shaped an I shape are inserted in a coil in such a fashion that the main iron core section of the block 1 has the coil over it, and next the convex and concave mating section 2a of the block 2 is struck into the convex and concave section 1a of the block 1 to form one body of stacked iron plates. Since the mating of the sections 1a and 2a is not one body because I shaped plates Y and Y' of the I shaped stacked iron plates block 2 are bound by a paper tape only, the I shaped plate Y can be inserted into the concave section of the block 2 without obstruction. The stacked iron core plates after the mating process and the coil can be transported as one body, making the assembly simple, and due to lapping of a plate X of the E shaped block and a plate Y of I shaped block, leaking magnetic fluxes decrease and noise will not develop.

IPC: H01S5/068
Filed: 1989-03-01
Abstract: PURPOSE:To prevent deterioration of high speed response characteristics when a driving current for a semiconductor laser is varied by connecting a predetermined number of transistors in a parallel transistor circuit to the semiconductor laser in parallel. CONSTITUTION:Only a predetermined number of transistor 4, in a parallel transistor circuit 2, are connected to a semiconductor laser 1 in parallel. The number of transistors 4 in this case is so selected that a current for producing required output is caused to flow through the semiconductor laser 1 and an optimum collector current is caused to flow through each transistor. Therefore, even if a driving pulse current IP is different for each semiconductor laser, the collector current in each parallel transistor circuit can be have a constant optimum value. Thus, deterioration of high speed response characteristics (rising/ falling characteristics) can be eliminated.

Title: Air-fuel ratio controller for internal-combustion engine
Inventor: MORITA TATSUROU
IPC: F02D41/36
Filed: 1984-03-16
Abstract: PURPOSE:To keep the generating torque of an engine constant, by adjusting an air-fuel ratio according to engine stability, then rarefying the air-fuel ratio as much as possible as stabilizing a degree of combustion, and aiming at improvements in a rate of fuel consumption, while distributing a compensation portion for the air-fuel ratio to each compensation portion for a fuel injection quantity and a suction air quantity, respectively. CONSTITUTION:A fundamental injection quantity (fuel injection pulse width) Q/N is calculated at an operational circuit. Next, at an air-fuel ratio compensation factor calculator 28, the number of cylinders where a counter value at every cylinder stored in a memory becomes the specified value or more than 1 during the specified period comes to the specified value, it is so judged that engine stability is worsened whereby an air-fuel ratio is adjusted to the rich side at once, and when the counter value fails to become the specified value, it is so judged that an engine is stabilized whereby the air-fuel ratio is adjusted to the lean side. At an air quantity and a fuel injection quantity as shown in illustration, that is, from an air-fuel ratio (a) point, in order to prevent generating torque from being varied, the (a) point is adjusted to a (b) point on the same generating torque line, so that it will do that the air-fuel ratio is merely compensated as far as a portion for DELTAalpha in distributing a compensation position for the air-fuel ratio to each compensation portion for the air quantity and the fuel injection quantity.
