Title: Line interface circuit
Inventor: NAKAZAWA KAZUO
IPC: H04N1/32
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To deal with the special service using polarity inversion operation before forming a DC loop by permitting a feeble current to flow so as to detect the polarity inversion of a line by means of detecting elements which are connected to the line in parallel. SOLUTION: When a forward current is made to flow in the detecting element D4 and a reverse voltage is impressed on the detecting element D5, the outputs of the detecting elements D4 and D5 becomes 0 and 1. Then, a polarity is inverted by a line exchange network and the outputs of the elements D4 and D5 are changed-over from 0 and 1 into 1 and 0. CPU detects it, forms the DC loop by adopting switches SW1 and SW2 as the ones at a (b) side and executes first response. The line exchange network detects the first response of a callee terminal so as to report a call originator number, the switches SW1 and SW2 are connected to a (c) side so as to open the DC loopa after detecting the number by the callee terminal and first response is released.  When the line exchange network detects it, an incoming call signal is transmitted, the callee terminal detects this so as to execute hook-up and the switches SW1 and SW2 are made to be at the (b) side so as to form the DC loop again.

IPC: B41J2/355
Filed: 1987-09-02
Abstract: PURPOSE:To eliminate discontinuity in printing by subdividing a single line into blocks with the overlapping ends and supplying correction power twice to the overlapping end after obtaining such electric power by application of a correction factor to an electric power corresponding to a density to be displayed by a thermal head drive device. CONSTITUTION:Of subdivided blocks, the first block contains the first pixel to the 457th pixel, while the second block contains the 407th pixel to the 889th pixel. The maximum energies to be applied to the first and second blocks with each overlapping 50 pixels heated between the first and second blocks, and the second and third blocks respectively, are taken to be E1, E2. The heat energy E to be supplied to these overlapping pixels subjected to heating is E=xsi1E1+xsi2E2, where 0<=xsi1<=1, 0<=xsi2<=1. The correction factor xsi1 is a linear decrease function of 1 for the 407th pixel, and 0 for the 40th pixel and 1 for the 457th pixel.

Title: Molding die for insulation of stator
Inventor: OKUDERA HIROYUKI
IPC: B29L31/34
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent the front end of a gate from being torn off, being left in a molding die, and interrupting the flow of a resin in the subsequent molding when a stator and the gate left in the movable half of the molding dies are ejected by providing a two-stage ejecting means which ejects the stator prior to the gate. SOLUTION: An ejector pin 9a for stator is positioned so that the lower end of the root section 9a1 of the pin 9a can nearly become the same position as that of the upper section of an ejector plate 9c. Therefore, when the plate 9c is pushed up, a stator is first pushed up by the pin 9a, but the front end section of a gate 5a remains in the gate 5a. The gate 5a is ejected by an ejector pin 9b for the gate 5a with a little time lag due to the clearance caused by the height difference S in a two-stage ejecting means. Since the front end section of the gate 5a is also ejected when the gate 5a is ejected, the front end section does not remain in a molding tool. Therefore, the front end of the gate 5a can be prevented from being left in the molding die.

Since the same output voltage as that of the first voltage variable characteristic filter 2b is supplied to the second voltage variable characteristic filter 2a, the same characteristic as that of the first voltage variable characteristic filter 2b is attached on the second voltage variable characteristic filter 2a. In such a way, it is possible to automatize the adjustment of an active filter.

Title: Frequency deviator for wave within intermediate infrared rays range
Inventor: MISHIERU PAPIYUSHIYON
IPC: G02B26/00
Filed: 1988-09-01
Abstract: PURPOSE: To prepare a comparatively long and integrated optical waveguide by providing a movably diffraction grating formed by the optical induction of a carrier on the surface of the optical waveguide integrated by a semiconductor. CONSTITUTION: The wave to shift the frequency is a wave 4 to be guided to be parallelly added to layers 3 and 2 for guiding that wave and its pulsation Ωi belong to an intermediate infrared range. The layer 2 is an intermediate layer, and the reference factor of that intermediate layer is set medium between the refraction factor of the layer 3 and the refraction factor of a substrate 1 so that a mode to be guided can be more effectively enclosed. The materials and thickness of the layers 3 and 2 are selected so that the loss of the mode to be guided for diffraction to the outside of the optical waveguide can be reduced as much as possible near the wavelength of the wave to be guided. Therefore, the wave 4 to be guided can interact over the full length of the optical waveguide. Thus, the high diffraction grating can be provided because of its long length.
