IPC: G01B3/10
Filed: 1991-12-13
Abstract: PURPOSE:To prevent slip of a take-up drum without causing damage, lowering of a resisting force, etc., of a measuring tape, by a method wherein a rotable roller is brought into contact with the outer periphery of a roll of the measuring tape and the resistance under its own weight is applied to the rotation of the take-up drum.

Title: Tracking controller for multibeam optical disk device
Inventor: KATO KIKUJI
IPC: G11B7/14
Filed: 1992-12-10
Abstract: PURPOSE:To attain the stable translation transfer by adding the difference signal, etc., of a tracking error signal to the output of a compensation circuit for translating a light spot line in a translation position control system through a mutual interference compensator. CONSTITUTION:The mutual interference compensator 30 is added to a conventional tracking control system, and it is controlled so that the positioning precision of both light spots of the translation position control system and a rotational position control system become equal. In the mutual interference compensator 30, the drawout point is set at immediately before the compensation circuit 25 for rotating the ligh spot line, and the addition point is set at immediately after the compensation circuit 21 for translating the light spot line. At this time, the eccentricity of one track T4 out of the tracks positioning tow light spots for detecting the tracking error signal is taken as the synthsis of the eccentricity D1 of the track T1 and the eccentricity deviation  D4-1 between both tracks when the eccentricity of the other side track T1 is taken as a reference. Thus, the stable translation transfer is performed.

Title: Production of carbon material for sliding current collection
Inventor: FUJIMOTO KENICHIRO
IPC: C04B35/52
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a carbon series sliding current collecting material having high strength, low electric resistance and high resistance to brittle fracture by a method wherein a carbonaceous powder material is admixed with specific quantity of metallic fibers and then it is molded and sintered and further subjected to heat treatment. CONSTITUTION:Metallic fibers are admixed by 5-60vol.%, preferably 10-45vol.%, for the total of a carbonaceous powder material and the metallic fibers. When it is lower than 5vol.% electric resistance does not decrease sufficiently whereas when it is higher than 60vol.% the carbonaceous powder material is not sintered sufficiently thus causing decrease of strength. Thus obtained mixture material is then molded or subjected to cold hydrostatic press and sintered at a temperature lower than the melting point of the metallic fiber under an environment of inert gas such as argon or nitrogen thus carbonizing the mixture material. It is further subjected to heat treatment for quenching the metallic fibers.

Abstract: PURPOSE:To make it possible to calculate the influence of a two-dimensional potential distribution on the characteristic parameters such as the threshold voltage of an SOIMOSFET in a simple one-dimensional model and to shorten the calculation time remarkably by taking in the characteristic parameters into the one-dimensional model. CONSTITUTION:A two-dimensional electric field directed from a drain electrode 7 towards a gate electrode 5 is approximated to a one-dimensional electric field which is constant in the longitudinal direction near a gate oxide film or an SOI layer. This approximation can be materialized by setting an equivalent electrode 8 which makes the above described one-dimensional electric field instead of the drain electrode. The location and the potential of the equivalent electrode 8 is found by analytically. Then, the characteristic parameters are determined based on the one-dimensional model.

Title: Shift register
Inventor: HARADA MOEMI
IPC: G11C19/28
Filed: 1987-12-29
Abstract: PURPOSE:To reduce the number of transistor devices and the area of a circuit and to easily substitute the shift register for an on-going register by providing a latch circuit and an output selection circuit in the circuit block of each output stage separately. CONSTITUTION:In the circuit block [for example, the circuit block (j) in a stage (j)] of each output stage of shift registers with constitution of (n) stages, an output stage selection circuit constituted as a tri-state buffer circuit and the latch circuit constituted as an inverter type FF are provided separately from the circuit block. The output stage selection circuit controls the fetch of the level conversion of a shift register driving signal to the circuit block by a FET which sets the circuit block at a preceding stage as a gate input signal at the circuit block in each stage. Also, the latch circuit is connected to the output of the output stage selection circuit, and it is to suppress the floating state of the output of the circuit. Therefore, it is possible to reduce the number of transistor devices compared with the on-going register, and also, since no NOR circuit is used, the area of the circuit can be reduced as a whole.
