Filed: 1989-12-26
Abstract: PURPOSE:To accurately perform air-fuel ratio control based on exhaust temperature by grasping cooling loss through detection of heat flow speed of gas which flows on a partial are inside a cylinder head, and estimating the exhaust temperature. CONSTITUTION:Exhaust gas temperature is influenced by heat loss of an internal combustion engine 11 and any cooling loss can be grasped by heat flux of gas which flows on a partial area inside a cylinder. Thereby an engine operation condition is detected by an operation condition detection means 13, the cooling loss is obtained from the heat flux measured by a heat flux detection means 12, and the exhaust temperature is estimated by a calculation means 14. In a comparison means 15, the estimated exhaust temperature is compared with the exhaust temperature preliminarily set. When the exhaust temperature exceeds at least the allowable value, an air-fuel ratio is controlled by a control means 16 to the richer side than that at previous air-fuel control.

Title: Photodetector
Inventor: HISA YOSHIHIRO
IPC: H01L31/10
Filed: 1989-12-25
Abstract: PURPOSE:To reduce a cross talk by providing a light absorbing layer under an electrode of a P-type compound semiconductor layer and by making this P-type compound semiconductor thinner than other parts. CONSTITUTION:A light absorbing layer 7 is formed on the surface of a P-type compound semiconductor layer 2, while an electrode metal 5 is formed on the surface of an N-type compound semiconductor region 3. When the layer thickness of the compound semiconductor layer is made small in relation to an absorption length at a wavelength of an object light, the light not absorbed out of the incident one in the N-type compound semiconductor region 3 is reflected at the electrode metal and traverses the compound semiconductor layer again. In the P-type compound semiconductor layer 2, however, the light not absorbed out of the incident one is absorbed in the light absorbing layer 7 on the surface of the P-type compound semiconductor layer, not traversing again the compound semiconductor layer. Thereby a cross talk is reduced, and since the P-type compound semiconductor layer 2 is thinner than the N-type compound semiconductor region 3, in addition, generation of an electron-Hall couple in the P-type compound semiconductor layer lessens further, whereby the cross talk is decreased.

Title: Reluctance type commutator motor
Inventor: BAN ITSUKI
IPC: H02K23/66
Filed: 1991-10-24
Abstract: PURPOSE:To quicken the rise and fall of a supply current and prevent generation of arc discharge between a commutator and a brush by holding a high voltage through charging of a capacitor with application of stored magnetic energy when current supply of excitation coil stops and then applying the high voltage of the capacitor to the excitation coil when current supply is conducted. CONSTITUTION:When a brush and a commutator are in contact, the terminals 24a and 24b are connected and a current is applied to an excitation coil 23a from DC power source terminals 2a, 2b. Next, when a rotor rotates and the burh is isolated from the commutator piece to open the loop between the terminals 24a and 24b, an energy accumulated at the magnetic poles charges a capacitor 31a through diodes 26a, 27a to convert it into an electrostatic energy to quickly drop current of the excitation coil 23a. Moreover, when the rotor rotates again and the brush is in contact with the commutator piece to close again the terminals 24a, 24b, a SCR 29a becomes conductive through a transistor 30a, a supply current of the excitation coil 23a rises quickly with a high voltage of the capacitor 31a and thereby an output torque can also be increased.
