Title: Production of trialkylaluminum
Inventor: IWAO TETSUYA
IPC: C07F5/06
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To obtain a trialkyl aluminum useful as a catalyst for polymerizing olefins at a high reaction rate in a high yield. SOLUTION: This method for producing the trialkyl aluminum comprises reacting an amorphous type aluminum-magnesium alloy uniform in the composition with an alkyl halide, if necessary, in the presence of methylaluminum sesquichloride, etc., as a reaction initiator in a solvent (e.g. n-hexane). The aluminum-magnesium alloy has an aluminum content of 35-45wt.% and a magnesium content of 55-65wt.%, and is obtained by melting aluminum and magnesium, and subsequently quickly cooling and solidifying the melted mixture at a rate of >=10<5> K/sec. The employment of the aluminum-magnesium alloy enables to accelerate the reaction and obtain the objective compound in a high yield within 15 hr or shorter, while conventional methods require a reaction time of approximately 24hr.

Title: Method and device for measuring sea salt particle
Inventor: IKEDA KOSUKE
IPC: G01N17/00
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To make the environment of a sea salt particle assessable rapidly with a compact and simple device by spraying the air containing sea salt particles to a copper plate, measuring the discoloration of the copper surface due to corrosion by measuring the amount of reflection of light on the copper surface, and calculating the adhered amount of sea salt particles. SOLUTION: A copper plate 1 that is a sea salt particle capturing martial is arranged so that it can travel at every fixed time by a drive motor 3, and a cover 2 with window is installed on the upper surface of the copper plate 1. Air is constantly sprayed from a blowing part 5 being located at the upper portion of the cover 2 to the window part of the cover 2. If a mist containing sea salt particles exists in the air and hits against the copper plate 1 via the window of the cover 2, the copper plate 1 is corroded due to the sea salt particle, thus discoloring the surface of the copper plate 1. Light is applied from an application part 6 to the copper plate 1 at the window part of the cover 2, and a light reception part 7 for detecting the amount of reflected light from the copper plate 1 is arranged toward the window part of the cover 2.  The amount of reflected light from the copper plate 1 decreases as the corrosion by the sea salt particles progresses and the output of the light reception part 7 also decreases. It is evaluated whether the a mount of sea salt particles is large or small according to the change in the amount of reflected light.

Title: Optical disk device
Inventor: SAKANE ATSUYUKI
IPC: G11B19/02
Filed: 1994-11-30
Abstract: PURPOSE: To eliminate unnaturality of a display by replenishing between the readout time and the searching time of a disk. CONSTITUTION: A control circuit 6 stores the elapsed time of a playing read out with an optical pickup PU3 in an RAM 10 as a variable T1. Moreover, a time when the display operation at the elapsed time of a playing is delayed with respect to the position of PU3 is added to T1 and stored in the RAM 10 as a displaying elapsed time of the playing T2. Then, in the case PU3 is moved from a ten times speed to a reproducing speed, when the calculated time just prior to the movement is delayed from the readout time just after the movement, the control circuit 6 performs a time display by replenishing the time of the difference between them. Thus, the display is returned without unnatuality.

Title: Angular velocity sensor
Inventor: SHIRATORI NORIHIKO
IPC: G01C19/56
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To obtain an angular velocity sensor which has a small size, a light weight, a thin thickness, and high sensitivity and the oscillation frequency of which can be adjusted accurately by providing through holes of such sizes that do not hinder the vibration of a weight body through a circuit board and a substrate so as to trim the weight body. SOLUTION: When an angular velocity acts on an angular velocity sensor, a weight body 28 moves due to a Coriolis force and, as a result, a sensor section 30 is deformed and electric charges are generated in a detection electrode 24. A circuit board 41 is put on the flange sections 52a of four pins 52 fixed to a substrate 51 and fixed to the sections 52a by soldering. Since through holes 51a and 41a of such sizes that do not hinder the vibration of the weight body 28 are respectively formed through the substrate 51 and board 41, the weight body 28 can be trimmed by irradiating the weight body 28 with a laser beam from the direction C. Since the trimming can be performed while the main body of the sensor is directly or indirectly fixed to the board 41 and substrate 51, the oscillation frequency of the sensor can be adjusted accurately.  After completing all adjustment, a rubber vibration insulator 61 provided with a recessed section 61a is fixed to the substrate 51 so that the insulator 61 cannot hinder the vibration of the weight body 28.

IPC: G05D3/10
Filed: 1988-11-28
Abstract: PURPOSE:To reduce the idle lever stroke and to attain the maximum availability of the stroke of a control lever by producing the electric signals is response to the control lever and its manipulated variable, and sending a control signal based on the electric signal. CONSTITUTION:A controller 2 calculates such a coefficient with which the latest maximum output value of a manipulated variable input device 1 is always equal to the minimum assured value in case the output value of the device 1 exceeds the minimum assured value set previously. This calculated coefficient is compared with the coefficient stored in a memory in the preceding time. When the former coefficient is smaller than the latter one, both coefficients are changed to each other for updating and stored in the memory. Then the controller 2 outputs a control signal corresponding to the valve obtained by multiplying the output value of the device 1 by the stored coefficient as long as the output sufficient enough to update the latest stored coefficient is not received from the device 1. Then an actuator is driven by the control signal of the controller 2.
