Title: Method and device for forging work
Inventor: MIYAZAKI TOYOFUMI
IPC: B21J13/02
Filed: 1990-05-11
Abstract: PURPOSE:To accurately manufacture a desired product at a low pressure by retreating a die pin by a volume equal to a forced volume of a punch synchronizing with the forcing motion of the punch. CONSTITUTION:When a work 7 is set in a forming hole 40 of the die and the punch 3 is forced in, the pressure of the punch 3 is given to the work 7 and the work is formed along with the force-in of the punch 3. In that case, the outer peripheral surface of the work is brought, first, into close contact with the side of the forming hole by the force in of the punch 3 and prohibited from moving and since the die pin 5 is retreated by a volume equal to the forced volume of the punch 3, a part on the side of the die pin of the work flows in a free state, an additional pressure by frictional force, etc., is not required to the punch 3 and the work 7 is formed only by the pressure nearly equal to the working force to the work.

Title: Method for transmitting or storing audio signal
Inventor: YANITSUKU MAIYUU
IPC: G10L19/04
Filed: 1990-05-10
Abstract: PURPOSE: To reduce a required bit ratio to obtain a uniform restoration quality by performing prediction and encoding to an adaptive code for a prescribed time with respect to a coefficient in the most significant position of conversion of each block of a sound signal. CONSTITUTION: In an encoder, a harmonic extraction circuit 82 dispatches coefficients going to a branch, which is not accompanied with prediction, or coefficients going to a branch, which has module and phase ADCPM, as a function of a matching signal received from a recursive spectrum rough estimate circuit 84. In the branch which is not accompanied with prediction 86, the number of precedences of phases and blocks is uniformly quantized for a prescribed time, and modules are non-uniformly adaptively quantized. In a prediction branch 88, prediction coding of a frequency characteristic reduces a ratio of bits to be assigned to the coefficient in the most significant pace of a spectrum and is led to a coding algorithm where looped adaptation or inverse quantization is combined to reduce auxiliary information.

Title: Filter provided with tunable pole frequency
Inventor: JIIRUTO EI DE BEAMAN
IPC: H03H11/12
Filed: 1991-04-26
Abstract: PURPOSE: To improve the operating characteristic of the filter circuit by compensating unideal performance of a mutual conductance element and providing a differentiation device to a feedforward path of an input signal. CONSTITUTION: An input voltage Vi10 is given to a capacitor C1 ' via a feedforward loop. A capacitance, of the capacitor C1 ' is in matching with a capacitance of a capacitor C1 and a mutual conductance of a mutual conductance element 36 is in matching with a mutual conductance of an input mutual conductance element 21. A parasitic conductance and capacitance are eliminated by matching the capacitance of the capacitors C1 , C1 ' and the conductance of the elements 21, 36. Since a frequency of a feedforward differentiation device is lower than a typical signal frequency of the filter circuit, a problem of a dynamic range is caused when the input signal Vi10 is fed to a variable gain amplifier 29, but it is solved by increasing a -3dB frequency of the differentiation device.

Abstract: PURPOSE:To insert a cartridge without receiving load from a pressing means by providing the pressing means pressing the cartridge when an opening and closing member is closed and releasing the pressing of the cartridge when the opening and closing member is opened. CONSTITUTION:An upper opening and closing cover 16b is opened and the process cartridge is inserted along guide parts 7a and 7b. When the cover 16b is closed, the upper surface of the cartridge is pressed by the pressing member 18a provided on the inner top panel of the cover 16b. Simultaneously, the projections 1a1 and 1a2 of a frame body abut on the abutting parts 7b1 and 7b2 of the guide part 7b. Then, the cartridge is positioned and the rotation thereof is regulated. Besides, a leaf spring 18b is fitted to a frame near the turning center of the cover 16b. Since a distance between a supporting point P1 and a point to which force is applied P3 where the spring 18b is pressed is longer than the distance between the supporting point P1 and the point of application P2 where the cartridge is pressed, the cartridge can be pressed by the spring 18b by small power. Therefore, the load added on the cover 16b is reduced.
