Title: Metallocene catalyst and production of polyolefin
Inventor: ISHIGAKI SATOSHI
IPC: C08F4/64
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To polymerize an olefin without using an arom. hydrocarbon and without being accompanied by fouling, by combining a metallocene compd. solubilized by the contact with an organometallic compd. in an aliph. hydrocarbon with a cocatalyst carried by a fine particulate carrier. SOLUTION: The aliph. hydrocarbon may be alicyclic. Examples of the organometallic compd. are organoaluminum (except aluminoxanes), organolithium, organozinc, and organomagnesium compds. An example of the metallocene compd. is bis(η<5> -cyclopentadienyl)zirconium dichloride. The amt. of the organometallic compd. mixed with the metallocene compd. is 10-800 times that of the transition metal atom of the metallocene compd. The cocatalyst, e.g. methylaluminoxane, is carried by a fine paticulate carrier such as silica or alumina.

Title: Rolling measuring apparatus
Inventor: HASHIMOTO TSUKASA
IPC: G01C19/72
Filed: 1995-01-10
Abstract: PURPOSE: To provide a rolling measuring apparatus which can continuously measure a rolling state of an object to be measured without lowering the work efficiently of construction, etc. CONSTITUTION: An optical gyro sensor package is composed of an optical fiber gyro compass 46 to measure the absolute direction of an excavator and a yaw rate sensor 48 to measure the relative direction of the excavator. The measurement of the absolute direction by the optical fiber gyro compass 46 can be carried out when excavation work by the excavator is stopped and the excavator is stopped. The yaw rate sensor 48 can be operated even at the time of excavation by the excavator and can continuously detect the relative direction. Consequently, the absolute direction of the excavator can be measured intermittently by the optical fiber gyro compass 46 and at the same time, independently of the driving state of the excavator, the direction of the excavator can be measured continuously by computing the relative angle alteration from the absolute direction by the yaw rate sensor 48.

IPC: A61B5/05
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent an adverse effect by magnetic noise due to imprudent, opening by locking the door of a magnetic shield chamber while operating a sensor part. SOLUTION: The opening/closing of the door 20 is detected by a door opening/closing sensor 22 and transmitted through a signal line 22a to a sensor driving switch 23 inside a sensor driving part and signal processing part B. In this case, when the door is closed, the sensor driving switch 23 is turned ON and the sensor part 3 is turned to an operation state and detects a magnetic field from a testee body. When the door 20 is opened, the sensor driving switch 23 is turned OFF and the sensor part 3 is not operated. The opening/closing signals of the door 20 transmitted by the signal line 22a are inputted to a data analyzer 10 and the opening/closing state information of the door 20 is displayed at a part of a screen together with other numerical values.  Further, while the sensor part 3 is operated, the door 20 is locked and the door 20 is opened and closed from the side of the data analyzer 10. Thus, the effect of the magnetic noise by opening during measurement is prevented.

IPC: H01L21/82
Filed: 1987-01-28
Abstract: PURPOSE:To improve the wiring process efficiency of layout, and make the perfect automating of wiring possible, by making the number of wiring channels in the wiring channel region of each cell array differ in accordance with each channel region. CONSTITUTION:In a semiconductor integrated circuit of gate array system, the following two regions are perfectly separated; cell regions 12-14 in which a group of cell transistors constituting logic is regularly arranged in one- dimensional direction, and wiring regions 15 and 16 in which wirings between each cell 11 are arranged. The respective numbers of wiring channels 17 and 18 in the wiring channel regions 15 and 16 are made different from each other. Thereby, even if arrangement and wiring are made from the central part of a chip, and the wiring is crowded there, the number of the wiring channels of the wiring channel region in the central part of a chip can be made larger than that of the regions excepting the central part. Thus the wiring efficiency can be improved, and automatic layout is enabled.

IPC: G11B15/52
Filed: 1993-01-11
Abstract: PURPOSE:To sustain the amplitude constantly at a predetermined level by amplifying a reproduction control signal delivered from a control based on a cut-off frequency and a gain being set according to the operating mode and then outputting the amplified reproduction control signal. CONSTITUTION:A control head amplifier 2 absorbs fluctuation in the amplitude level and the frequency characteristics of reproduction control signal between various types of tape T and operating modes thus producing a reproduction control signal having constant amplitude level and frequency characteristics at all times. Resistors R1-R4, capacitors C1-C3, and switches sw1-sw4 are inserted between the inverted input terminal and the output terminal of an amplifier 2 depending on the type of the tape T, normal reproduction mode, and quick/rewind mode in order to set the gain and cut-off frequency of the amplifier 2. In case of an iron oxide tape, for example, SW1 and SW2 are turned ON whereas SW3 and SW4 are turned OFF under normal reproduction mode thus setting the gain at 60dB and the cut-off frequency at 1.8kHz.

Title: Rotary body apparatus
Inventor: SHIMIZU FUKUZO
IPC: B04B9/12
Filed: 1987-01-31
Abstract: PURPOSE:To suppress the conduction of the heat generated in the rotor of a motor to the main body of a rotary body, by providing a heat resistance increasing part to the flange part positioned between the rotor and the main body of the rotary body. CONSTITUTION:When hysteresis motor 17 is energized, a rotor 9 is rotated and a rotary body main body 1 is rotated with the rotation of the rotor 9. Herein, when the motor 17 is energized, the rotor 9 generates heat by eddy current loss and the heat is ready to be conducted to the rotary body main body 1 through the flange part 3 of a shaft 2. In this case, since the flange part 3 is formed into a pulley shape and a hole 8 is provided to the axial center part of a center shaft part 5, the cross-sectional area of the heat conducting route reaching the rotary body main body 1 from the rotor 9 becomes an extremely small value as compared with a columnar flange part. That is, a heat resistance increasing part is formed to the flange part 3 and the heat generated in the rotor 9 becomes difficult to be conducted to the main body 1.

Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To set many data sending bit rate classes by distributing alternately plural data multiplexing channels to plural programs based on the number of data packets of each data group. SOLUTION: The data multiplexing channels which are conventionally occupied by a single data program until it's finished are alternately used by the data packets of plural data programs. At the same time, a single data program that is conventionally multiplexed by means of only a single channel is multiplexed to plural data multiplexing channels. Furthermore, the data packets of plural data programs are divided into groups for organization of data programs. The charts show an example where eight scanning lines 10H to 13H and 273H to 276H which are available to the scanning line multiple data broadcast are used and proportionally distributed in the data packet number ratios 8:14:20... 9:9:3 of data groups (a, b, c...n, o, p).
