Title: Frequency measuring method
Inventor: EGAWA AKIRA
IPC: G01R23/02
Filed: 1980-05-07
Abstract: PURPOSE:To make measurement of frequencies possible without receiving the in fluence of noise and amplitude change by calculating the time when an input sine wave signal zero-crosses by using a circuit analysis method and taking the inverse number of the period thereof. CONSTITUTION:A sample holding circuit 1 sample-holds the amplitude analog value at each point of time of an input sine wave signal according to the sampling pulses outputted from a timing circuit 4 based on clock pulses and applies the value thereof as amplitude information to an operator 3. A counter 2 calculates time data by counting the clock pulses and applies this to the operator 3. Based on these data, the operator 3 makes circuit analysis, thereby determining the period of the sine wave signal. The period determined by this is taken of reciprocal by the circuit of the subsequent stage, whereby the frequency of the sine wave signal is determined. Thereby, the highly accurate frequency measurement is accomplished without being affected by noise and the change of amplitude.

Title: Accomodation of pitch fiber bundle
Inventor: MAEKAWA HIROSHI
IPC: B65H54/78
Filed: 1981-04-20
Abstract: PURPOSE:To prevent a pitch fiver bundle from being broken, by winding off the pitch fiber bundle from a bobbin which is set on a paying-out device and rotated at a slow speed after the pitch fiber bundle is wound up on the bobbin so that the pitch fiber bundle is carried at a slow speed on an under conveyor belt for carrying it to an unmelt treating region. CONSTITUTION:A pitch fiber bundle which is once wound up onto a bobbin 3 is transferred to a paying-out device 19 and then is paid out onto a conveyor belt 25 for feeding the pitch fiber bundle to an unmelt treating region. That is, each grooved winding bobbin 3 inserted onto each motor shaft is rotated at a slow speed in the direction of winding off, and the pitch fiber bundles P fall at a low speed to the degree that they are allowed to fall mainly under their weight. An air sucker 30 above the conveyor belt 25 has suction force to the degree that prevents the paid-out pitch fiber bundles from being rewound up onto the rotating bobbins, and also has its lower end flared such that fluid flow is retarded for preventing the pitch fiber bundle from impinging upon the conveyor belt 25.

Title: Semiconductor device
Inventor: TOOMASU SHIYUTOTSUKUMAIERU
IPC: H01L23/31
Filed: 1989-03-13
Abstract: PURPOSE: To bring a silicon substrate and a semiconductor element into a passive state by disposing a PSG layer (silicophosphate glass layer) on an SIPOS layer (semi-insulating polycrystalline oxygen doping silicon layer). CONSTITUTION: An SIPOS layer 3 covers directly the surface 2 of a silicon substrate 1, and is deposited, and the reaction of SiH4 with N2 O is utilized under the typical reactive conditions, and the oxygen content percentage of the SIPOS layer 3 is adjusted by the partial pressure ratio of SiH4 to N2 O. The doping of phosphorus into the SIPOS layer 3 is performed simultaneously with the vapor deposition or performed later, and then a PSG layer 4 is deposited on the SIPOS layer 3, and in that case phosphorus is added thereto to reduce the remaining stress of silicon oxide. However, when the concentration of phosphorus is too high, since corrosion is generated in an aluminum electric conductor 5 disposed on the PSG layer 4 as a metal cover layer 5, boron is substituted for phosphorus in some degree, and in this case, the BPSG layer (borosilicophosphate glass layer) is produced.  Thereby a semiconductor element and a silicon substrate, particularly, the weak edge and rim can be passivated.

Title: Idling controller of internal combustion engine
Inventor: OBATA TAKEAKI
IPC: H02P9/00
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the control hunting by a method wherein the generated energy of an alternator is changed to adjust the load on the alternator for an internal combustion engine. SOLUTION: The integral feedback control value of the supplied air flow of an internal combustion engine is calculated from a revolution detected by a revolution detecting means (a) and a target revolution calculated by a target revolution calculating means (b). An operation value of the supplied air flow control valve of the internal combustion engine is calculated by a supplied air flow control valve operation value calculating means (e) in accordance with the integral feedback control value and signals from control value calculating means (d) for the control other than the integral feedback control. The correction value of the generated energy of an alternator is calculated by an alternator generated energy correcting means (f) from those values.  As a result, if the hunting is caused by the integral feedback control of the supplied air flow, the control hunting can be eliminated by adjusting the load on the alternator for the internal combustion engine.

Title: Semiconductor integrated circuit device
Inventor: SAKAMOTO MASATAKA
IPC: H03K3/023
Filed: 1991-03-26
Abstract: PURPOSE:To avoide a trouble generated due to the transmission of an intermediate potential by transmitting the intermediate potential outputted by the logical circuit of a preceding stage side as an 'H' or 'L' binary logical signal by the logical circuit of the succeeding stage side which receives the output of the logical circuit of the preceding stage side. CONSTITUTION:Logical circuits 31 and 32 multiple-connected in order to form a delay circuit 30 are constituted so that potentials Vt1 and Vt2 being the boundary of the 'H' and 'L' binary logical level can be different from each other. Thus, even when the signal of the intermediate potential is included in a signal inputted from an outside, and the intermediate potential is outputted from the logical circuit 31 of the preceding stage side, the intermediate potential from the logical circuit of the preceding stage side is not the intermediate potential of the logical circuit 32 of the succeeding stage side. The intermediate potential from the logical circuit of the preceding stage side is transmitted as a logical signal in an 'H' area, and outputted by the logical circuit 32 of the succeeding stage side. Therefore, even when the intermediate potential which is not the 'H' or 'L' binary logical potential is generated, the trouble generated due to the potential is generated, the trouble generated due to the transmission of the intermediate potential to the other part can be prevented.
