Title: Polishing apparatus and method for detecting final point of polishing
Inventor: IWABUCHI KAZUHIRO
IPC: B24B37/07
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To eliminate collateral work such as the setting work of polishing conditions by continuously detecting the polishing degree of the wafer substrates during polishing process and by preventing occurrence of dispersion of flatness in respective wafer substrates. SOLUTION: The holding disk 4 of a pressing head portion of a polishing apparatus holds the back surface of a wafer substrate 6, while pressing the polishing surface of the wafer substrate 6 to the grinding wheel 7 or the abrasive cloth of a platen portion 9. Then, the holding disk 4 is upwardly lifted by a stroke in proportion to the degree of pressing provided by a bellows-like spring 5 securing the holding disk 4, and the vertical level of the holding disk is detected by a displacement detecting portion 2 within the pressing head 1 so that polishing is started after the vertical level is identified as the standard level in starting polishing.  With the change in polishing degree of the wafer substrate 6, the location of the holding disk 4 also changes following the polishing degree, so that the displacement is continuously measured at the displacement detecting portion 2 in order to recognize the polishing degree based on measured data, allowing to automatically control the final point of polishing. Accordingly, dispersion of flatness respective wafer substrates 6 can be prevented.

Abstract: PURPOSE:To improve interest for play and prevent the play from monotony by constituting a pinball machine such that a right generating play condition is provided to increase the frequency of the generation even when a shot ball winning a prize in a prize winning ball device does not win the prize in a first specified prize winning port, but wins the prize in a second specified prize winning port. CONSTITUTION:When a shot ball wins a prize in a first specified prize winning port 59, a right generating play condition is provided, and when the shot ball wins the prize in start prize winning ports 18a, 18b under the right generating play condition, a variable prize winning ball device 13 is opened for a predetermined period. When the shot ball wins the prize in second specified prize winning ports 60a, 60b to turn on second specified prize winning ball detectors 62a, 62b, a drive motor is stopped for a fixed time every time they detect a change in a drive motor stop position detector. Thus, the shot ball winning the prize in a ball inlet 44 to be dropped from an end of a ball guiding trough 46 when the drive motor is stopped is given a extremely high possibility of winning the prize in the first specified prize winning port 59. Thus, interest for the play is improved while the play is prevented from monotony.

IPC: H04L7/00
Filed: 1990-08-16
Abstract: PURPOSE: To make uninterest its dynamic motion in the signal power of a band terminal area without receiving the effect of the frequency separation of a band-pass filter by forming a timing phase vector. CONSTITUTION: The peripheral components of Nyquist frequencies +1/T and -1/2T are extracted from a baseband signal by two band-pass filters BPF-U15 and BPF-L17, they are correlated with each other by a multiplier 19, and a difference between two T/2 correlation products is formed by a subtracter 23. By low-frequency-filtering the difference between the correlation products, short fluctuation largely reduces. Thus, the timing phase vector tpvn (τ) counterfeits the expected value of an input signal A phase error Δτn showing a phase difference between tpvn (τ) and a reference timing phase vector tpvREF is calculated by a phase error generating component 33, a sampling phase τis formed by a timing phase adjusting component 33, and controlling it by a timing means 35.

Title: Suction device for engine
Inventor: ASAYAMA YOSHIAKI
IPC: F02M25/07
Filed: 1984-10-15
Abstract: PURPOSE:To control a highly accurate exhaust gas recirculation rate as well as to control a stable idling speed, by installing a suction throttle valve, which opens or closes a suction passage, and an oxygen sensor which detects oxygen content in suction air mixed with exhaust gas. CONSTITUTION:A first suction throttle valve 4, which opens or closes a first suction passage 3 and simultaneously fully closes it in time of idle running in an engine 1, is installed. An exhaust gas recirculation control valve 18 makes exhaust gas recirculate from an exhaust pipe 17 to the suction passage 3. An oxygen sensor 11 detects oxygen content in suction air in which the exhaust gas is mixed. In order to control an idling speed, a second suction throttle valve 7 alone is opened or closed, while an exhaust gas quantity to be recirculated is controlled for feedback. Thus, a highly accurate exhaust gas recirculation rate and a stable idling speed both are controllable simultaneously.

Title: Tial intermetallic compound having high strength, high toughness, and high ductility
Inventor: FUJIWARA YOSHINARI
IPC: C22C14/00
Filed: 1991-08-27
Abstract: PURPOSE:To improve strength, toughness, and ductility by specifying the average crystalline grain size and the amount of contained oxygen in a TiAl intermetallic compound, respectively. CONSTITUTION:This TiAl intermetallic compound has a composition consisting of 36-60 atomic % Al and the balance Ti and also has <=50mu average crystalline grain size and <=1.0wt.% contained oxygen content. When the average grain size exceeds 50mu, the regularity of crystal orientation is increased and, as a results, transgranular cleavage is allowed to occur and the strength, toughness, and ductility of the above intermetallic compound are deteriorated. Further, when the amount of contained oxygen exceeds 1.0wt.%, the toughness and ductility of the above intermetallic compound are deteriorated similarly. Because this intermetallic compound is obtained by regulating the amount of oxygen contained in powdery raw materials at the time of preparing these powdery raw materials and also regulating the crystalline grain size by means of heat treatment, the refining of crystalline grains and the reduction in the amount of contained oxygen can be relatively easily attained.

Abstract: PROBLEM TO BE SOLVED: To improve the discharging state of wash water by installing a flow path for drainage branched from a piping connecting a heating means and a wash water nozzle and a valve for drainage opening and closing the flow path for drainage to the downstream of an air supply means and controlling the air supply means. SOLUTION: When pressure in a hot-water storage tank 17 reaches specified pressure or less, a valve is opened, a flow path 34 for drainage is branched from the downstream-side connecting piping 9 for a vacuum breaker 18, from which air is introduced into the tank 17, and a flow-regulating changeover valve 19 opening and closing the flow path 34 is mounted. A main solenoid valve 15 and a wash-water supply means are opened and air inflow from the breaker 18 to the piping 9 is prevented during a time up to stop indication after wash-water discharge to a wash water nozzle 20. The valve 19 is brought to an open state during a time when the nozzle 20 is forwarded and retreated, and a part of wash water is discharged from the flow path 34.  Accordingly, the mixing of air into initial discharge water from a nozzle for washing and uncomfortable feeling can be prevented, and the force of wash water is weakened during the forwarding and retreating of the nozzle for washing and the moistening of clothing, etc., can be obviated.

Filed: 1981-12-29
Abstract: PURPOSE:To obtain highly accurate and continuous speed information from a shaft encoder by bringing projected current speed close to actual speed with readjustment thereof in respective measuring cycles comparing the two speeds. CONSTITUTION:A series of encoder pulses 1 with the cycle inversely proportional to an unknown speed are applied to an input line 2. An equivalent cycle 53 of a pulse 1 corresponding to the initial projected speed is applied to a second counter 6. When it is correct, the second counter 6 is counted down accurately to zero upon the end of an encoder pulse cycle 51. When it is not correct, the position of a first counter 4 is reduced by one unit for speed to be projected anew and reloaded with a difference 54 between the equivalent cycle 53 and a cycle 55 corresponding to the newly projected speed. The foregoing process is repeated until the cycle 51 comes to the end.
