Title: Control device for vehicular suspension
Inventor: HIWATARI MINORU
IPC: B60G17/015
Filed: 1992-06-29
Abstract: PURPOSE:To promptly control the rolling of a vehicle at the time of cornering by forecasting a rate of change in lateral acceleration associated with the cornering of the vehicle, thereby changing a threshold value by which the attenuation characteristics of a damper are fixedly kept low, into a small one so as to be controlled, when it is judged that the forecasted value is over a set value. CONSTITUTION:A controller 5 switches the damping force characteristics of a damper 1 as have been elected as follow: when the absolute value of a vertical displacement speed over a spring, which is obtained by an integrating circuit 51, is equal to or more than a shreshold value which is selected and set by a shreshold value change control means 8, high damping force characteristics (a) shall be selected if the speed of a suspension stroke obtained by a differentiating circuit 52 is identical in direction to the vertical displacement speed, however, low damping force characteristics (b) shall be selected if the speed of the suspension stroke is different in direction from the vertical displacement speed. And when the vertical displacement speed is less than the threshold value, the low damping force characteristics (b) shall be selected, so that the damper 1 shall be of low attenuation characteristics. Thus, as mentioned above, damping control where riding comfort is the first consideration, is assumed at the time of straight ahead running and steering or normal running similar to the aforesaid straight ahead running and steering, and clamping control is promptly assumed if a vehicle is changed in attitude at the time of cornering.

Title: Production of aluminum nitride fine powder
Inventor: KUGIMOTO JUNICHI
IPC: C01B21/072
Filed: 1993-07-13
Abstract: PURPOSE:To obtain aluminum nitride fine powder suitable for mass production using an inexpensive and readily handleable raw material by reacting metallic aluminum with aniline and then burning the resultant precursor in an atmosphere of a nonoxidizing gas. CONSTITUTION:Metallic aluminum is made to react with aniline and the resultant precursor is then burned in an atmosphere of a nonoxidizing gas to afford the objective fine powder. Coarse massive aluminum, ingot, etc., are undesirable as the metallic aluminum used due to slow reaction with the aniline. Since the surface of the metallic aluminum is usually coated with an oxide film, a fresh surface is preferably formed by a method for cutting, crushing and atomizing, etc., just before the reaction so as to accelerate the reaction thereof with the aniline. When water is dissolved and present in the aniline used, a hydroxide film is formed on the aluminum surface to prevent the aluminum from reacting with the aniline. Thereby, the aniline is preferably dehydrated according to a usual method.

Title: Switching circuit network
Inventor: MAAKU BOASOO
IPC: H04Q11/06
Filed: 1983-10-20
Abstract: A switching network for selectively connecting at least one input time-division channel on an input link (IL) to at least one output time-division channel on an output link (OL). The network is organized around a closed-loop link (10) on which circulates a multiplex message carrying 512 time-division exchange channels. The input and output links (LE and LS) are respectively multiplexed onto an input multiplex link (IML) and an output multiplex link (OML) which are coupled to the closed loop (10) by a switching module (SM). Each switching module comprises an input buffer (IB), an output buffer (OB) and a local buffer (LB) the addressing of which is selectively controlled by a time slot counter (CRT) or a corresponding pointer memory. So-called "broadcast" connections coupling one input channel to several output channels, and "in-cast" connections coupling several input channels to one output channel, can be established. Each of these connections uses only one exchange channel.

Title: Machine controller
Inventor: HAYASHI SHINNOSUKE
IPC: G05B19/042
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a machine controller which starts rewriting a program, etc., without causing an unexpected driving state even if a machine is in a driving state when the program, etc., is rewritten. SOLUTION: When it is decided that an engine is rotating (S600), a request to stop the engine is sent to a memory rewriting machine (S700) and an engine control routine (S300) is not rewritten. When an operator stops the engine and the memory rewriting machine makes a request to rewrite again, a rewriting control program is received from the memory rewriting machine (S900) right after a step S800, and the program is executed (S1000 and S2000). Then a new engine control routine (S300) is started by resetting. Therefore, the engine is at a stop both when the program is rewritten and when it is restarted, so the mechanism of an automobile never enters an unexpected driving state even when control program data are altered.
Patent JP-S6257851-A (JP)
Title: Device for feeding main spindle lubricating oil
Inventor: YOSHIMI TAKAHITO
IPC: B23Q11/12
Filed: 1985-09-04
Abstract: PURPOSE:To prevent the generation of heat in a main spindle at the time of restarting by detecting that said main spindle has stopped for a certain period of time or above by a main-spindle stoppage detecting means, and making a control means stop feeding a lubricating oil until the restarting of rotation, and stopping the feeding of more than necessary quantity of lubricating oil to a bearing under a stopped condition. CONSTITUTION:When a main spindle 6 is stopped and as the stopping condition has continued for the set time of a main-spindle stoppage detecting timer T1, the set time of the timer T1 is expired at this point of time, closing an electromagnetic closing valve 22. Thereby, an oil and air feeding operation is discontinued and the feeding of oil and air is stopped until the rotation of the main spindle 6 is restarted and the main-spindle stoppage detecting timer T1 is reset, preventing more than necessary quantity of lubricating oil from being collected in a ball bearing. Since the set time of the main spindle stoppage detecting timer T1 is set shorter than the set time of a lubricating interval timer T2, the number of feeding times of oil and air after the main spindle has stopped is once or less, minimizing the feeding of unnecessary lubricating oil. Thereby, the generation of heat in the main spindle at the time of restarting the main spindle can be effectively prevented.

Title: Gas valve for automatic extinguishment and flame extinguishing device using the valve
Inventor: FUKITA TERUO
IPC: A62C35/02
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To spurt a flame extinguishing gas to a spot intended for flame extinguishment at the time of fire outbreak using a low-cost structure which ensures an unfailing gas ejection. SOLUTION: This flame extinguishing device uses a gas valve with a gas supply pipe 24, introduced into a body 22, through which a flame extinguishing gas is supplied to the interior. In addition, the gas supply pipe 24 is movable between a blockage position where a gas outlet 24c on the tip side of the gas supply pipe 24 is blocked with a blocking member 25 and an opening position where the gas outlet 24c is opened. Further, the gas supply pipe 24 is urged to the opening position side with the help of a compression coil spring 28. The gas supply pipe 24 is locked at the blockage position resisting an urging force when a temperature is normal and is unlocked by the deformation of a temperature detecting member 30 when the temperature is high. This behavior of the pipe 24 is attributed to the temperature detecting member 30 with a bimetal installed on the gas valve.

Abstract: PURPOSE:To provide an automatic self-checking function with pumping operation repeated, wherein the margin condition allow a specified times of motor starting is left at all times, by comparing the sensing pause time according to a pause time sensing means with the threshold value-pause time which guarantees the specified times of continuous start of motor by the insertion of a coil. CONSTITUTION:The time with a start voltage decreasing means 14 inserted is measured as the start time A by a start time measuring means 16. The predetermined relation of the pause time to this start time A is accommodated in a data table 18-1, while a pause time sensing means 20-1 senses the pause time B relative to the start time A by reference to the data table 18-1. In case the pause time sensed at the previous start still remains when the start time A is measured at the current time, the pause time is sensed as a time obtained by adding the pause time sensed anew to the remaining pause time. The pause time B is fed to a comparing means 22 and compared with the specified threshold valve-pause time C. If this sensed pause time B is below the threshold value C which guarantees the specified times of motor continuous starts, driving a motor associating with automatic checking is admitted, and if exceeding, driving the motor shall be prohibited.
