Title: Dust suction switching device in polishing and pumping feeder
Inventor: FUKUDA YOSHIAKI
IPC: A63F7/02
Filed: 1989-02-03
Abstract: PURPOSE:To increase a suction force largely by providing a dust suction switching device for performing opening and closing of a dust suction pipe interlocked with opening/closing action of a passage switching device so as to make it possible to eliminate dust produced in a polishing grain cleaning device by suction only when this cleaning device is operating. CONSTITUTION:A passage switching device A is provided for reducing polishing grains directly or leading them to a polishing grain cleaning device 23 through a polishing grain cleaning passage 21. A dust suction pipe 22 connected with this polishing grain cleaning device 23 is connected with a dust suction switching device B at the other end, and opening/closing action of this dust suction pipe 22 is performed by the dust suction switching device B interlocked with opening/ closing action of the passage switching device A. That is, the dust suction pipe 22 is released only when the polishing grain cleaning device 23 is operating, so dust produced in the cleaning device 23 is eliminated by suction, and the dust suction pipe 22 is closed when the polishing grain cleaning device 23 is stopped, where only dust produced in a directing device 26 is eliminated by suction.

Title: Abnormality detecting device for controller
Inventor: ISHII MITSUAKI
IPC: G05B9/02
Filed: 1986-02-05
Abstract: PURPOSE:To set an internal combustion engine system under a safe state even though a power supply line or an earth line of a detector has disconnection, by securing such a constitution where a trouble mode control signal generating means produces the signal to control a controlled system under a prescribed state when a trouble is detected by trouble detecting means and the controlled system is controlled under a safe state equal to the state where a signal line has disconnection. CONSTITUTION:When a power supply line of a target rotational frequency setting device 2 has disconnection, the earth potential is supplied to an A/D converter 12 through a resistance 16 as the 1st voltage level. In case an earth line has disconnection, the 3rd voltage level (high potential) approximately equal to the power supply voltage level is supplied to the converter 12 since the resistance value of the resistance 16 is higher enough than that of a variable resistance 21. When an output signal line has disconnection,the earth potential serving as the 1st voltage level is supplied to the converter 12 like a case where the power supply line has disconnection. Then a high potential if detected is not defined as the target rotational frequency and the target rotational frequency is set at the safe side like in case of the earth potential.

Filed: 1987-02-06
Abstract: PURPOSE:To perform normal focusing servo which reflectance an optical disk has, by dividing a focusing error signal by the peak value of a light quantity signal to automatically eliminate the influence of the reflectance of the used optical disk. CONSTITUTION:A peak value SP of a light quantity signal S proportional to the reflectance of a used optical disk 5 is held by a peak holding circuit 14 in a first focusing driving period when an objective lens 4 as the focusing means is driven in one direction before the focus leading-in operation. A focusing error signal FE which has information of focusing and is proportional to the reflectance of the optical disk 5 is divided by this held peak value SP, and focusing servo is performed, based on the resultant signal. The focus leading-in operation is performed in second and subsequent focusing driving periods following the first focusing driving period. Thus, the influence of the reflection factor of the used optical disk 5 is automatically eliminated, and normal focusing servo is performed whichever reflectance the optical disk 5 has.

Title: Manufacture of transistor
Inventor: OISHI YOSHIRO
IPC: H01L21/203
Filed: 1988-02-05
Abstract: PURPOSE:To reduce the resistance of a p-type layer with the thickness of the p-type layer being kept thin, by forming a recessed portion with slant sides by selective etching of a GaAs substrate and by depositing an n-type layer, a p-type layer and an n-type layer in order on the bottom of the recessed portion by the molecular beam epitaxial method. CONSTITUTION:A 100-facet GaAs substrate is etched selectively using a phosphoric acid etching fluid to form a recessed portion illustrated in Figure (a). On this substrate, an n-type GaAs layer 2, a p-type GaAs layer 3 and an n-type AlGaAs layer 4 are deposited by the MBE method using Si and Be as dopants. At this time, 100 facets appear on the bottom of the recessed portion, while other facets appear on slanted portions. Therefore, the n-type layer, the p-type layer and the n-type layer are deposited in order on the bottom. However, only a p-type layer is deposited on the slanted portions. Since the thickness of the p-type layer on the slanted portions is thick, the base resistance is low. By this method, an easy manufacture of an HBT is available by forming an emitter electrode 6 and base electrodes 5 as shown in Figure (b).

Filed: 1988-02-05
Abstract: PURPOSE:To enable a thin film transistor with a sufficient transconductance, by a method wherein Si ions are implanted into a polysilicon film, and a two- step annealing process is then performed. CONSTITUTION:A polysilicon film 2 is formed on allover the surface of a silica glass substrate 1 by means of a lower pressure CVD system. Subsequently, Si ions are extensively implanted into the polysilicon film 2 by means of an ion implanter. As an implantation condition, the Si implantation dose is set to more than 1X10<15>dose/cm<2>. This implantation of Si ions makes the polysilicon film 2 amorphous. Next, in order to prevent the silica glass substrate 1 from deforming and the polysilicon film 2 from cracking, the polysilicon film 2 is selectively etched so that it is left on only a transistor area for a TFT with being removed on the other area. Next, an annealing is performed for 30 hours or more at 500-700 deg.C to enlarge a crystal grains. Thereafter, when an annealing is again performed for 1 hour or more at above 900 deg.C, a large number of crystal defects which are generated in the crystal grain are extinguished. According to the manufacturing process described hereinabove, the crystal grains are enlarged and the electron mobility is increased.

Abstract: PURPOSE:To eliminate jitter from a transmission signal by providing a signal detector set by a head bit of a reception signal and reset after a prescribed time count and inputting a timing signal extracted from a reception data to a digital phase control oscillator only during the set period of the detector. CONSTITUTION:An input blocking gate circuit 108 is placed to an input section of a DPLL (digital phase controlled oscillator) 104 and the input of the timing signal from a tuning circuit 102 to the DPLL is blocked while looking into the end point of the reception signal. The gate signal for blocking the input is set to the head bit of the reception signal and reset after a prescribed time count in a signal detector 107, the gate signal brings the block gate 108 into the passing state during the set period, that is, the DPLL is locked to the timing of the reception signal, and the gate signal blocks the timing of the reception signal by the block gate 108 during the reset period to run the DPLL freely. Thus, the clock of the head of the transmission signal 118 from the data transmission section 106 loss jitter in the transmission clock for the transmission data because the DPKK is in the free run state.
