Patent JP-H079666-A (JP)
Title: Printer
Inventor: ROBERUTO UIREMU TEIERUROOI
IPC: B41F17/28
Filed: 1993-06-18
Abstract: PURPOSE: To adjust the speed of the side wall of an object interposed between mandrels to the corresponding speed with a printing roller capable of obtaining proper printing quality by providing an annular ring to a means for rotating mandrels with respect to a mandrel wheel and elastically pressing the shaft parts of the respective rotatable mandrels. CONSTITUTION: A mandrel rotating assembly includes the ring 28 held with respect to an mandrel wheel in concentric relation around a central fixed hub by a rotatable assembly 30. Next, the ring 28 is separated from an end surface 54a by a relatively short distance to be certainly pressed to the shafts 22 of mandrels. The ring 28 is produced from a material generating no slip with respect to the shafts. The driving of a belt 74 is different from the rotary driving of the mandrel wheel and the other member of this apparatus. That is, it is important to change of the mandrels independently of that of the mandrel wheel because the rotational speed of the mandrels is desired to be increased, for example, corresponding to the material of a container according to circumstances.

Title: Heat treatment method of steel rolling roll
Inventor: SHIMOTAMURA OSAMU
IPC: C21D9/38
Filed: 1978-12-01
Abstract: PURPOSE:To prevent propagation of crack by applying compressive residual stress to both surface and inside of roll, by adjusting the cooling temperature of hardening after rolling Cr-Mo-V steel into roll form. CONSTITUTION:Cr-Mo-V steel containing C by 0.4-0.6%, Cr by 2.5-5%, Mo by 0.5-1.5%, V by <0.5%, Si by <1.5%, and Mn by <1.5% is processed to obtain a roll for hot rolling. This roll is uniformly heated to hardening temperature of 1000 deg.C+ or -50 deg.C, and is colled at a relatively high cooling speed of 500-1000 deg.C/hour to about 500 deg.C lower than the temperature of causing perlite transformation. Holding this temperature for a while, the temperature in the center of the roll is made equal to that of the surface. Cooling slowly again at a rate of 10-20 deg.C/hour, the surface of the roll is transformed to bainite, and compressive residual stress is applied to the surface and inside of the roll by expanding them.

Title: Analog-digital converter
Inventor: UCHIMURA KUNIHARU
IPC: H03M3/04
Filed: 1983-08-15
Abstract: PURPOSE:To obtain a high S/N with a low quantized accuracy by forming a quantized output into a tri-state level and spreading a DC converted error with a pulse signal so as to change over the full scale of a D/A converting circuit depending on the magnitude of the input signal level. CONSTITUTION:An input analog signal is added to an output from a pulse generator 10 at an adder 2, subtracted with a velue D/A-converting (6) an output of a quantizer Q4 sampling signals in a frequency higher than an input frequency, and the result is inputted to an integration device 3. An integrated output signal is quantized into three levels, a reference voltage VREF1 or over, a middle value between VREF1 and VREF2, and the VREF2 or below by two voltage comparators 12A, 12B of a quantizer 4 and outputted to a digital filter DF7 and the D/A converter 6. The DF7 eliminates a pulse signal spreading a DC converting error from the generator 10 and outputs a digital signal corresponding to the input analog signal. The output signal is detected by a signal amplitude detecting circuit 11 and the full scale of the D/A and the DF7 is changed over into two stages depending on the magnitude of the signal amplitude so as to improve the S/N ratio to a low input level signal.

Title: Speed measuring device
Inventor: MAIKERU JIYON GIRU
IPC: G01F1/66
Filed: 1989-06-09
Abstract: PURPOSE: To accurately measure flow rate of a fluid flowing between transducers by detecting a flight time of acoustic signal transferred between two transmission/reception transducers two-way. CONSTITUTION: Transducers T1 and T2 are used for both transmission and reception of acoustic signal. Assuming that a gas flowing in a meter is of sound velocity C and flows at speed V along the common axis to two transducers T1 and T2, with interval being L, the flight time of ultra-sonic wave pulse between the transducers T1 and T2 comes to be L/(C+V) in the direction from T1 and T2 and L/(C-V) in the direction from T2 to T1. The flight time is measured with a propagation sensing circuit. The form of a drive signal from a micro processor 100 which controls the propagation sensing circuit is a carrier of short pulse modulation where phase-inversion of 180 deg. is inserted, or a tone- burst signal. The phase-inversion acts as a timing maker for recognizing reception pulse, independent of a momentum value of received signal.
