Title: Manufacture of semiconductor photo receptor
Inventor: YASUDA KAZUTO
IPC: H01L31/18
Filed: 1984-05-31
Abstract: PURPOSE:To make the distribution of avalanche multiplication factor uniform by a method wherein the same crystal layer as a multiplication layer is formed by the second crystal growth, and next a p-n junction is set up by forming an impurity region coming from the surface into the multiplication layer. CONSTITUTION:An n type InP buffer layer 2, an n type InGaAs photo absorption layer 3, an n type InGaAsP acceleration layer 4, an n type InP field control layer 5 and the n<-> type InP multiplication layer 6 are successively grown on an n<+> type InP substrate 1 by applying liquid phase epitaxial growth. The layers 6 an 5 are mesa-etched. The crystal layer melted back by the second liquid phase epitaxial growth is the surface of the layer 6. No matter how this surface comes rough, it becomes part of the p<+> type InP light receiving region 7 when the titled element is completed, becomes a part with no application of electric fields, and is not contributed to the distribution of multiplication factor.

Title: Phase locked loop circuit
Inventor: HIROSE TSUNEO
IPC: H03L7/14
Filed: 1992-04-28
Abstract: PURPOSE:To prevent a fault from being caused in an output signal even when a fault takes place in an input signal. CONSTITUTION:A phase comparator 1 is connected to an input side of a loop switch 51 and an output terminal of the phase comparator 1 is connected to a phase fault detector 52. An output terminal of the loop switch 51 is connected to a resonance circuit 53 and its output controls a voltage controlled oscillator 3. The resonance circuit 53 acts like a low pass filter of a quadratic system. The resonance frequency f0 is made almost coincident with a fluctuation component frequency of an input signal. The phase fault detector 52 is not required depending on the kind of the fault of the input signal. Thus, even when a fault takes place in the input signal and an output from the phase comparator is not obtained, the oscillating frequency follows to the fluctuation frequency component of the input signal accurately.

Title: Setting system for data link
Inventor: OOBA EIJI
IPC: H04L29/08
Filed: 1984-05-31
Abstract: PURPOSE:To reduce the load on the CPU of an exchange by detecting the bit string of a specific pattern sent as respective LSBs from the transmission system of the opposite party terminal controller in communication. CONSTITUTION:An LSB monitoring part 51 detects the transmission of the bit string of the specific pattern from the transmission system and then knows directly without any intervention of a CPU that the opposite party requests data transmission. Then, data and signals are transferred to and from a data terminal through an interface 63 and a switch 73 is switched at the lower-side contact under the command of an MPU22. Consequently, a data link is set and the terminal gets ready to receive a data signal.

Abstract: PURPOSE:To selectively use either one of the original synchronizing speed and the peripheral speed of 1/2 of the synchronizing speed by providing changeover switches in 2-phase windings and a capacitor. CONSTITUTION:The first windings 10A are selectively connected at one end through a changeover switch 14A to either one terminal of a power source 12. Simultaneously, the second windings 10B are selectively connected at one end through a changeover switch 14B to either one terminal of the power source 12. The other terminals of the windings 10A, 10B are further connected at one through the third changeover switch 14C and a capacitor 16 at the other directly to the other terminal of the power source 12. The third changeover switch is switched at every 1/2 cycle synchronously with the power source voltage, and the first and second switches are switched by displacing 1/2 cycle at every one cycle of the power source voltage synchronously with the switching operation. By this arrangement, a synchronous speed corresponding to one half is obtained.

Title: Air purifier
Inventor: MASUDA TERUO
IPC: B01D53/38
Filed: 1987-05-06
Abstract: PURPOSE:To make the replacement of contaminated dust collecting paper easy by providing, along dust collecting electrodes of an air purifier, a means of readily inserting and removing the paper which collects dust such as smoke. CONSTITUTION:A gas containing dust such as tobacco smoke is forced into an air purifier by driving an air blow fan 9 and introduced in a frame member 3, with large dust particles removed through a prefilter 7. Such gas is negatively ionized due to a corona discharge generated between a negative discharge electrode 1 and a dust collecting electrode 2 with a high voltage applied thereto. Then, the dust particles are negatively charged in contact with the gas, travelling to the positive dust collecting electrode 2. Inasmuch as the dust collecting paper 5 inserted along the dust collecting electrode 2 has an apparently semiconductive property, the negatively charged dust particles are attached to the positively charged side of the dust collecting paper 5. Thus, the contaminated dust collecting paper 5 may be removed for replacement from a dust collecting electrode slit, with electric current turned off.
