Title: Compact zoom lens
Inventor: HASHIMURA JUNJI
IPC: G02B15/16
Filed: 1990-06-07
Abstract: PURPOSE:To offer the low-cost, compact zoom lens which consists of a small number of lenses while maintaining high optical performance by composing each of a front and a rear group of two lenses and using at least one lens whose both surfaces are aspherical. CONSTITUTION:The zoom lens consists of two components, i.e. the front group with positive refracting power and the rear group with negative refracting power in order from the object side and the air gap between the front group and rear group is varied to vary the focal length of the whole system. Then the front and rear groups each consist of two lenses, and a least one lens is the lens whose both surfaces are aspherical. This zoom lens is shortened in overall length and reduced in movement quantity so as to make the constitution compact, and consequently the refracting power of each group needs to be increased, so that tendency of deterioration of aberrations becomes remarkable. For prevention against the tendency, the front and rear groups each consist of two lenses and at least one both-surface aspherical lens is used.

Filed: 1989-06-14
Abstract: PURPOSE:To obtain excellent environmental resistance and mechanical strength by a simple technique by using a glass film forming method using a sol-gel method for formation of the film to coat the optical disk. CONSTITUTION:The magneto-optical recording medium 3 is formed on a disk substrate 1 and the entire part of the disk is coated with glassy protective films 2, 2' formed by using the sol-gel method.

Title: Contour correction circuit
Inventor: SAKURAI KUNIO
IPC: H04N5/208
Filed: 1990-06-08
Abstract: PURPOSE:To attain proper contour correction in response to an inputted video signal by synthesizing a video signal to be subject to contour correction with an output of a contour signal processing means generating a contour signal with a smaller amplitude as a luminance level of the video signal to be subject to contour correction is larger and its amplitude change is larger. CONSTITUTION:A luminance level detection circuit 22 detects a luminance level of a video signal inputted to an input terminal 20 and a change detection circuit 24 detects a change in the video signal inputted to the input terminal 20. An arithmetic circuit 26 adds outputs of the circuits 22, 24 and applies the result to a contour signal processing circuit 28 as a control signal. Thus, the contour signal processing circuit 28 outputs a contour signal with a smaller amplitude as the luminance level is higher and its amplitude change is larger. The contour signal outputted from the contour signal processing circuit 28 is added to the video signal inputted from the input terminal 20 at a synthesis circuit 32 and the result is outputted externally from an output terminal 34. Thus, proper contour correction in response to the video signal to be subject to contour correction is implemented.

Abstract: PURPOSE: To provide a drive controller for a vehicle which can regenerate the braking energy from a wheel to its maximum and obviate the necessity to decelerate the vehicle, at the time of deceleration of the vehicle, and suppress the supply of fuel to minimum and accelerate the vehicle again smoothly. CONSTITUTION: Braking energy can be regenerated by making a motor generator generate electricity when a vehicle is detected to be in deceleration. Moreover, when vehicle need out be decelerated, that is, there is a possibility of reaceleration, a speed change control means changes the transmission into such optimum speed change stage that the revolution of the motor generator 2 comes closest to the specified revolution besides being under the specified revolution, so it becomes easy to synchronize the revolution of an engine 1 and the revolution of the motor generator 2 with each other. Furthermore, when synchronizing the revolution of the engine 1 to the revolution of the motor generator 2, the fuel consumption for increasing the revolution of the engine 1 can be suppressed, so the fuel consumption can be improved.

Title: Electronic circuit module
Inventor: MIO SHIGEMI
IPC: H01L21/66
Filed: 1982-09-01
Abstract: PURPOSE:To detect the risk of the breakdown of terminal connecting parts when the breaking possibility is present, by providing monitoring wirings in a multilayered substrate and in a semiconductor chip so that the parts between monitoring connecting parts are connected and one circuit is constituted. CONSTITUTION:Each monitoring part 3 is connected by an intrachip wiring 4 which is provided along each side of a semiconductor chip 1. Meanwhile, a multilayered ceramic substrate 5 has terminals at the positions corresponding to ordinary terminals 2 and the monitoring terminals 3. The parts between the monitoring terminals 3 and the part between the monitoring terminal 3 and a monitoring terminal 6 at the outside of the chip are connected by wirings 7 in the multilayered ceramic substrate 5. When a current is conducted through an electronic circuit module, the semiconductor chip 1 is heated and thermal expansion occurs. Conversely, when a power source is turned OFF, the temperature is decreased and the chip is contracted. Thus shearing stress is repeatedly applied to soldered connecting parts. When the power source is turned ON and OFF for more than certain number of times, thermal fatigue breakdown occurs. The first breakdown occurs at the monitoring terminals 3, which are located at the out side where the shearing stress is the largest. Therefore, opening of the monitoring terminal 6 of the electronic circuit module occurs before the ordinary terminals 2 are broken.

Title: Method for controlling page printer
Inventor: TAKEUCHI NOBUITSU
IPC: B41J21/00
Filed: 1982-08-31
Abstract: PURPOSE:To save time for form expansion and to shorten printing speed, by expanding only data without expanding a form every time in an electrophotographic printer. CONSTITUTION:Form information in a form buffer is transferred to an operation part by a form transfer command from a host computer 1. The operation part 2 expands the form information in a page memory 3. After the form expansion, data are sent from the computer 1 to the operation part 2. On the basis of the data, the operation part 2 originates data to form a clear table and sends the data to a clear controlling part 4. Simultaneously, the operation part 2 expands printing data in the memory 3. Subsequently, the operation part 2 reads out the data expanded in the memory 3 and sends the read-out data to a printer mechanical part 6 as a video signal. After completing said transmission, the operation part 2 sends a clear command for the data part to the controlling part 4. Receiving the command, the controlling part 4 clears only the data part of the memory 3. Consequently, the form information is left in the memory 3 as it is.
