摘要:
This invention relates to a vehicle cruise controller which controls engine output and gear shift position such that a detected vehicle speed is identical to a target vehicle speed. A shift to lower gear is performed when a difference between the target vehicle speed and detected vehicle speed reaches a first predetermined value .alpha..sub.1. A mechanism is provided for estimating a travel resistance of the vehicle, the travel resistance when this difference has reached a second predetermined value .alpha..sub.2 which is less than the first predetermined value .alpha..sub.1, being learnt as a maximum drive torque FB of the engine. A shift to higher gear is made when the estimated travel resistance has become less than this learnt maximum drive torque FB after the shift to lower gear. In this way, gear shift hunting during cruise control when the vehicle is climbing or descending slopes, is suppressed.

An apparatus and method for measuring a temperature of a high temperature liquid contained in a furnace. An optical fiber covered with a metallic tube is inserted through a passageway inside a nozzle arranged on a furnace wall of the furnace. The nozzle communicates with an interior of the furnace containing the liquid, and gas is supplied into the passageway inside the nozzle to prevent the nozzle from clogging. The metal-covered optical fiber is fed through the passageway inside the nozzle into the liquid such that spectral light radiated from the liquid enters a tip of the metal-covered optical fiber and is propagated therealong. The temperature of the liquid is determined by a radiation thermometer, coupled to the metal-covered optical fiber, based on the spectral light propagated along the metal-covered optical fiber.

In a microprocessor, a minimum instruction code length is set to a predetermined number of bits (e.g. one byte) length. One feature of the invention is that an instruction set which can selectively expand the instruction code length at a unit of the predetermined number of bits is used. Another feature is that an operand addressing mode and a type of operation for an operand are designated by separate predetermined number of code bits which are coded in a common coding scheme so that an instruction decoder is shared by those codes.

A semiconductor logic device having arrays of logic elements and chains of logic cells alternately arranged in a direction substantially perpendicular to the direction of the chains of logic cells in a surface portion of a semiconductor substrate. Each of the logic element arrays has input and output leads extending from the array in the above-mentioned direction substantially perpendicular to the direction of the chains of logic cells so that each of said logic cell chains is in an electrical connection with two adjacent logic element arrays via the input and output leads.

In order to compensate for the effect of a by-pass passage which by-passes air about the engine throttle valve when a predetermined vacuum prevails downstream thereof, or the delay in air flow within the induction system in response to the demand for engine power, a target torque value is derived based on the engine speed and the accelerator pedal depression amount and this value is used in connection with one or both of the fuel supply and the air flow control. In some embodiments two basic injection pulses are developed and one is selected to suit the instant induction conditions. In other embodiments, selectively delayed target torque values are used to individually modify the throttle valve control and injection fuel supply amount.

A machine for cleaning a coupler consisting substantially of a male coupler element and a female coupler element, especially mating surfaces related parts thereof is proposed for avoiding fouling thereof in advance of practical coupling of both the elements. The machine is provided with a ring tube type cleaner unit suspended from a detachable top cover of a cleaning box. The inside space of the ring tube constitutes a liquid chamber supplied with cleaning water from a source and delivers from a number of nozzle openings formed through the inner wall of the ring tube, for delivery of sweep water jets in the center of the ring tube, where the tip and to-be-coupled ends of both the coupler elements are positioned at a small mutual distance. After cleaning jobs, either one of the male and female coupler elements is advanced to mating position for establishing a tight contact with the other one of the coupler elements for avoiding otherwise frequently encountered, disadvantageous fouling.
摘要:
A semiconductor integrated circuit with a nonvolatile memory has a plurality of nonvolatile data memory elements arranged in a matrix and a means for reading data from the memory elements in accordance with an address signal which specifies a position in the matrix. A protecting data memory element for storing at least one-bit protection data is disposed in the matrix. Whether operations such as a programming (i.e., writing), erasing or reading with respect to the data memory elements will be allowed or inhibited is determined in accordance with the contents of the protecting data memory element. In other words, data security in an arbitrary area of the matrix can be accomplished based on the content of the protecting data memory element.
