Title: Safety device for work floor in high ground work vehicle
Inventor: SUZUKI YUUSUKE
IPC: B66F9/24
Filed: 1989-04-20
Abstract: PURPOSE:To ensure the safety in no contact with an obstacle by providing constitution in such a way as setting up on a work floor a reflecting ultrasonic sensor connected to a boom operating circuit interlocked, when the ultrasonic sensor oscillates a detection signal, stopping movement of a boom. CONSTITUTION:Any of the four ultrasonic sensors S1 to S4, mounted to a handrail of a work floor, is assumed to detect an obstacle in the above. For instance, when the ultrasonic sensor S4 detects the obstacle, a relay R4 in an address 4 is deenergized breaking a work contact R4 in an address 5, and this address relay R5 is deenergized. As a result, by breaking a work contact R5 in a control signal draw out line connected to an operating circuit of a boom, its operating circuit is turned off. That is, the boom is stopped moving by actuating an emergency stop circuit or an interlock circuit built in the operating circuit of the boom.

Title: Magneto-resistance effect type magnetic head
Inventor: SAWADA TAKESHI
IPC: G11B5/39
Filed: 1982-06-15
Abstract: PURPOSE:To improve the reproduction efficiency of a short wavelength for a magneto-resistance effect (MR) type magnetic head, by laminating the MR elements. CONSTITUTION:An MR element 3 is laminated with a soft magnetic thin film 6 via an insulated layer 7. In such a constitution, a closed loop is formed by the film 6 and the line of magnetic force of the element 3 to absorb the diamagnetic field generated from the film 6 and the element 3 by their relative magnetic functions. When the diamagnetic field is reduced, a change is produced in the magnetizing direction 9 of the element 3 in a minor signal magnetic field owing to a signal magnetic field. This improves the sensitivity. Furthermore the quantity of applied bias magnetic field can be greatly reduced. As a result, the signal of a recording medium is never demagnetized. Thus the reproduction of a short wavelength is possible.

Title: Ghost eliminating device
Inventor: IGA HIROYUKI
IPC: H04N5/21
Filed: 1983-06-07
Abstract: PURPOSE:To eliminate residual ghost signal due to nonlinearity of a weighting circuit by constituting the device that an attenuating means is inserted between a transversal filter and an adding means so that the amplitude level of a ghost cancelling signal is larger than the level of the ghost cancelling signal applied to the adding means. CONSTITUTION:Only C10 among tap gains is 0.5 when a ghost signal SG is eliminated. The ghost signal must be eliminated with the tap gain C10 set to 0.5, but the ghost signal SG remains unerased actually in a pattern signal SP part because of the nonlinearity of a weighting circuit 2A. In setting an attenuation (k) of a variable attenuator 26 to -6dB, the tap gain C10 is to be set to 1.0. The weighting circuit 2A can be used with a smaller differentiation gain Gd by changing the tap gain C10 from 0.5 to 1.0 (two times of 0.5) in this way, thereby decreasing the unerased ghost signal SG at the pattern signal SG part.

Filed: 1980-07-25
Abstract: PURPOSE:To set the output of a laser beam according to a measured value when the measured value is not reference surface potential and perform image formation by measuring the potential of the latent image after irradiation of the laser beam onto a recording medium by prescribed signals. CONSTITUTION:Prior to image formation, a photoreceptor is scanned by laser light based on a prescribed driving reference signal E1 to create a sample image, and the surface potential thereof is measured. The measured value VS is compared with reference potential VL and when they do not coincide, the laser driving signal value E2 of the time when VL attained is obtained from the characteristic curves at which VS is attained by said reference signal E1. The surface potential (corresponding driving signal value Ei of VS<i>) coinciding with the measured value VS is read out and is outputted. For example, when the corresponding driving signal E2 from one curve of said characteristic curves is resulted with respect to said measured value VS, this signal E2 is used as the driving signal for the laser light source for the purpose of image formation; thereafter, the image by the video signal is made.
