IPC: B41J11/42
Filed: 1982-12-29
Abstract: PURPOSE:To prevent a stagger in printing from occurring after starting printing, by a method wherein a recording medium is positioned at an initial set position, and thereafter a trigger pulse is impressed on a recording medium feeding power amplifier. CONSTITUTION:A change-over switch 22 is turned ON when stop positioning of a recording paper is completed, whereby an integrating circuit 23 is discharged, and a discharge current is earthed, so that a voltage is generated and is inputted into a gate circuit 17 as a trigger pulse.

Abstract: PROBLEM TO BE SOLVED: To improve the productivity at a low cost by adjusting the deviation of a code phase between a signal from a spread code generating system of a receiver and a reception signal with a variable timewise position of a reference pulse so as to reduce phase adjustment using variable delay elements. SOLUTION: An identification signal 201 is given to a synchronization circuit 103, in which the signal is subjected to correlation calculation with a spread code *PNO from a synchronization code generator 104 and a correlation peak and a timewise position of a reference pulse signal 205 via a variable delay element 301 are matched to acquire a code synchronizing signal. The spread code *PNO and a carrier recovery spread code PNO have the same code phase and a carrier recovery circuit 106 recovers a carrier 206. Then a signal 204 is multiplexed with the carrier 206 by a mixer 107 and the product is given to an LPF 108, from which a code division multiplex base band signal 207 is obtained. The delay time is corrected by a fixed delay element 302 and the result is outputted from an A/D converter 109 and a demodulation code generator 110.  The adjustment by using the variable delay element is only the adjustment of the reference pulse as above and the productivity is improved at a low cost.

Title: Heterobipolar transistor
Inventor: MIYAWAKI MAMORU
IPC: H01L29/737
Filed: 1988-09-21
Abstract: PURPOSE:To restrict injection of holes into an emitter and reduce recombination current by providing a shallow (n) layer between the emitter consisting of a non-oxide material with a wide forbidden bandwidth and a base with a narrow forbidden bandwidth. CONSTITUTION:An n layer 13 is formed between a semiconductor layer 14 which becomes an emitter with a wide forbidden bandwidth and a base layer 9 with a narrow forbidden bandwidth. Since this n layer 13 is shallow, holes are injected from the base 9 to the (n) layer 13. But, since the forbidden bandwidth of the emitter 14 is wide, a barrier is formed on a valence electron side, injection of holes into the positive emitter 14 is restricted, and the location where electric field strength due to pn junction is the maximum shifts to the junction interface between the (n) layer 13 and the base (p) layer 9, thus also reducing recombination current.

Filed: 1993-09-21
Abstract: PURPOSE:To stably heat and join slabs by installing plural units of inductors for generating magnetic fields for heating slab ends in a width direction and unifying the phases of the currents to be impressed to the respective inductors. CONSTITUTION:The rear end of the preceding slab 1 and the front end of the succeeding slab 2 are connected to each other by a combination of a heating treatment and pressing treatment.
