Title: Pitch detecting device
Inventor: DAISHIYOUJI TAKESHI
IPC: G10L25/90
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To accurately find a pitch cycle fast and accurately even when a speech waveform is a complicated waveform containing an overtone component or when a fine noise is superposed on the speech waveform. SOLUTION: A binarization part 8 which has a masking zone nearby the zero level converts a digital speech signal into a binary signal. Then, a timer 9 measures the inversion intervals of the binary signal to find successive zero- crossing intervals of the digital speech signal and stores them in a RAM 10. A pitch arithmetic part 11 assumes that the pitch cycle is the sum of 2n pieces of zero-crossing interval data as to n=1-4, calculates a reproduction rate as the degree of matching in each pitch cycle of each zero-crossing interval data constituting one pitch cycle, and employs the assumption by which the highest reproduction rate is obtained to find the pitch cycle.

Title: Amplifier circuit and display device
Inventor: OKAMOTO NOBUYUKI
IPC: H03F3/183
Filed: 1995-01-19
Abstract: PURPOSE: To suppress the generation of a smear and a sag owing to feedback capacity through the cascade connection of active elements. CONSTITUTION: The signal inputted from a signal input terminal 30 is amplified by an NPN transistor(TR) 34 and an NPN TR 81 cascaded thereto and outputted from a signal output terminal 53. When the frequency of the signal is low, the impedance of a capacitor 43 becomes large and the signal component is substantially not supplied to the base of a PNP TR 40, which operates as a constant current source. When the frequency of the signal is high, on the other hand, the PNP TR 40 outputs a constant current on which the signal component is superposed. Consequently, mainly, the rise characteristics of the output signal is improved. An NPN TR 81 is cascaded to the collector of the NPN TR 34, so none of the signal component appears. Consequently, the signal component is never fed back to the base of the NPN TR 34 on the basis of the feedback capacity of the TR 34.

Title: Control of blast at blast furnace stove
Inventor: NAGAO MASAYUKI
IPC: C21B9/00
Filed: 1979-01-22
Abstract: PURPOSE: To maintain blast to a blast furnace at a constant temperature at all times during blast by a method wherein the outlet temperature of each blast stove is newly introduced as control factor when blast stoves for the blast furnace are operated in staggered parallel blast operation.  
     CONSTITUTION: There are provided outlet thermometers between a mixing chamber MC1 of a first blast stove HS1 and a blast valve HV1 and between a mixing chamber MC2 of a succeeding blast stove HS2 and a blast valve HV2, both blast stoves being operated by staggered parallel blast operation. Temperature signals T 1 , T 2  are detected by an outlet temperature comparator CM. When the draft to the succeeding stove HS2 is started while the first stove HS1 is drafted, it is sometimes possible that at first the temperature of blast from the succeeding stove is lower than that of blast from the first stove. In this case, the polarity of the output of a temperature regulator C1 is reversed through the outlet temperature comparator CM by a signal inverter IN. The signal is transmitted to a blast valve regulator C2. When the blast temperature is higher than set temperature, the blast valve WV1 of the first stove is throttled, and the blast valve WV2 of the succeeding stove is controlled in the direction of opening to keep constantly blast temperature to the blast furnace.

Title: Recoilless pistol
Inventor: SENDAI SHIGERU
IPC: F41A25/10
Filed: 1990-01-17
Abstract: PURPOSE:To reduce recoil and shock at the time of firing and contrive a higher accuracy of fire, by mechanically absorbing upward recoil at the time of firing. CONSTITUTION:With a trigger of a pistol pulled, a hammer 6 is released to cause ignition at a primer, thereby firing a bullet 7 forward. Upon the firing, recoil is generated in a main body 1 of the pistol. The pistol 1 is divided into two parts, i.e., a part 2 and the main body 1, and the part 2 is slid backward simultaneously with a shock generated upon firing. The part 2 incorporates a strong spring 3 so as to absorb the firing shock, and a stopper 4 provided at a rear part prevents the part 2 from slipping off. It is thereby possible to reduce the shock and recoil upon firing, to eliminate unintentional movement of the hand or hands in firing, and to enhance accuracy of fire.
