Title: Clock phase variable circuit
Inventor: KAJIWARA MASANORI
IPC: H03L7/081
Filed: 1986-03-12
Abstract: PURPOSE:To optionally change the phase of the output clock of the second frequency divider connected to the output of a loop, and having a regulated division ratio, by performing a control to change temporarily the division ratio of the first frequency divider provided at a feedback path in a phase locked loop. CONSTITUTION:A phase locked loop circuit which phase-locks an output signal to an input clock signal, is constituted of a voltage controlled oscillator 101, a frequency divider 102, and a phase comparator 103. By providing the second frequency divider 104, and dividing the output clock of the voltage controlled oscillator 101, the output clock can be obtained. Meanwhile, by providing a control means 105, and controlling the first frequency divider 102 so as to change its division ratio temporarily, a change to complement the change of the division ratio by the oscillation frequency of the voltage controlled oscillator 101, is generated. Since the second frequency divider 104 divides the oscillation output clock of the voltage controlled oscillator 101 with a regulated division ratio, the phase of the output clock is varied corresponding to the change of the oscillation frequency of the voltage controlled oscillator 101. A changed phase, thereafter, is maintained unless the oscillation frequency of the voltage controlled oscillator 101 is varied.

IPC: B01D7/02
Filed: 1987-03-11
Abstract: PURPOSE:To industrially and advantageously obtain the titled compound having a good form, by feeding high-temperature gas-containing pyromellitic anhydride together with a cooling gas to an empty column type collector at a specific wall temperature, exchanging heat, passing through the collector under specific condition and recovering needle crystals from the bottom of the collector.

Title: System for detecting incoming call
Inventor: ARAI MASATAKA
IPC: H04M1/64
Filed: 1983-03-30
Abstract: PURPOSE:To use a device such as automatic answering telephone set by connecting in parallel with a main station connected to a PBX or the like by detecting a call signal from a pulse exchange using an intermittent signal having a short period such as 16Hz of a private branch of exchange PBX or the like as a call signal while distinguishing it from a dial pulse. CONSTITUTION:A pulse detecting section 11 generates a detecting signal corresponding to an input signal in a signal detecting section 4. An intermittent time detecting section 12 is set by the trailing of the said signal, counts a prescribed number, e.g., 450 and generates a detecting signal. Thus, an incoming detecting section 13 is set by the leading edge of a pulse signal when a pause period of the pulse signal is shorter than 450ms and generates an incoming detecting signal. On the other hand, when a dial pulse is transmitted from a telephone set, since the dial pulse has a pause period being >=450ms between numbers as a minimum pause, when the pulse detecting signal is generated again, the intermission time detecting signal is turned off and then no incoming detecting signal is generated from the incoming detecting section 13.

Filed: 1987-03-10
Abstract: PURPOSE:To cause wafers to be formed symmetrically in a simple process and to reduce their bends, by forming a polysilicon layer between two sheets of single-crystal silicon wafers so as to unify them and next forming semiconductor elements on these single-crystal silicon wafers. CONSTITUTION:In order to upgrade adhesiveness of polysilicon layers 3 formed between two sheets of single-crystal silicon wafers 1 whose both surfaces are mirror-polished, a drying process in succession to a hydrophilic process is performed and the polysilicon layers 3 are made to adhere to each other and junctioned. When high-temperature processing is performed in this state, surfaces of the polysilicon layers 3 are coupled with each other so that two sheets of the single-crystal silicon wafers 1 are unified. Next, a semiconductor element is formed thereon. Since the wafers are thus formed to interpose the polysilicon layers 3 therebetween and formed symmetrically in the center of the polysilicon layers 3, stress generated in the element formation process is exerted symmetrically to itself and so bends of wafers are reduced.
