Patent JP-H03266298-A (JP)
Title: Memory effect semiconductor device
Inventor: MIZUSHIMA YOSHIHIKO
IPC: G11C11/42
Filed: 1990-03-15
Abstract: PURPOSE:To directly read optical information with light by writing and reading optical information by using the refractive index changing phenomenon of an element made by a photoelectron generated with the light incident on a semiconductor. CONSTITUTION:An electric field more than 1000V/cm is impressed between electric poles 2-2 and 2-3 as an average electric field. Since a GaAs semiconductor 2-1 is a high resistance element, a current flowing in the element is small. Then, when a device is irradiated with the light of energy higher than the energy gap of the semiconductor, light hupsilon irradiating the semiconductor 2-1 increases carriers in the semiconductor 2-1 and a photoelectron travels to the electric pole 2-2. Even when light stimulation is removed in this condition, the internal current of the element remains. At this time the carriers are increased and the refractive index of the element becomes small compared with one before light irradiation. Thus, irradiating light information can be read by measuring a refractive index change optically.

Title: Device for controlling engine ignition timing
Inventor: SASAKI MASAHIRO
IPC: F02D45/00
Filed: 1989-03-18
Abstract: PURPOSE:To suppress knocking surely at any time when knocking is detected by delaying an ignition timing by a constant delay amount value followed by knocking control by the use of calculated delay angle. CONSTITUTION:During the operation of an engine, data L representing an engine load is calculated with a CPU in an electronic control device 18 from an engine rpm according to a crank angle sensor 16 and an intake flow rate according to an air flow sensor 17. A slice level corresponding to the data L is also calculated. A knocking level is detected from a knocking signal taken via a knocking signal detection circuit 11 from a knocking sensor 10 and compared with the slice level to determine the occurrence of knocking. When the judgment is affirmative, an ignition delay constant value set in a ROM 21 is set as an ignition delay amount to delay the ignition timing followed by delaying of the ignition timing by the use of calculated ignition timing delay value.

Title: Preparation of synthetic resin foamed body with excellent bending strength
Inventor: ITOU RIYOUICHI
IPC: B29C48/90
Filed: 1980-05-16
Abstract: PURPOSE:To obtain molded goods having an orientation property by a method wherein synthetic resin, foaming agent and reinforcing material are kneaded at the softening temperature of the synthetic resin or higher and after they are let to pass through a wide clearance once and to foam, they are let to pass through a clearance having gradually-decreasing sectional areas in the extruding direction. CONSTITUTION:During the rotation of the screw 5 of an extruder body 2, foaming agent, synthetic resin and short fibers like glass fibers etc. are kneaded.
