Title: Rotating device
Inventor: ISHIKAWA KIYOSHI
IPC: A61M16/00
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To perfectly automatically regulate rotating speed and oxygen supplying quantity to a preferable relation and provide a precise result through a simple operation by providing an oxygen supplying device for supplying, to a rotating patient, aspiratory oxygen to a position suitable for respiration of the patient. SOLUTION: The communication of a shaft horizontal hole 17 with a sleeve hole 16 is started when the rotating speed of a rotating shaft 6 is gradually raised, and the force for pushing up the lower end of a sleeve 11 by the centrifugal force of a weight 9 overcomes the elastic force of a spring 10 and pushes up the sleeve 11 to allow the sleeve hole 16 to communicate with the shaft horizontal hole 17. Thereafter, the push-up of the sleeve 11 is continued with the rise of the rotating speed, and the flowing area by the superposition of both the holes 16, 17 is increased until the sleeve 11 reaches a certain position.  Therefore, the rotating speed required for a patient and the supplying oxygen quantity required in a set with it are preliminarily calculated, and the form and size of each hole 16, 17 as realize these numerical values are properly set, whereby a desired result can be provided.

Title: Production of thick plate of heat treated high tensile trength steel
Inventor: IKI HIROSHI
IPC: C22C38/14
Filed: 1992-11-05
Abstract: PURPOSE:To produce a thick plate of heat treated high tensile strength steel excellent in toughness at low temp. by subjecting a slab of a steel containing specific trace amounts of Nb and Ti to hot rolling under specific temp. conditions and then to normalizing treatment. CONSTITUTION:A slab of a steel having a composition which contains, by weight, 0.05-0.15% C, 0.02-0.80% Si, 0.60-2.50% Mn, 0.005-0.020% Nb, and <0.020% Ti and where Ti/Nb<=0.70% is satisfied is heated up to a high temp. region of 1100-1250 deg.C, hot-rolled, and worked into a thick steel plate of >=50mm plate thickness. Subsequently, by subjecting the steel plate to normalizing treatment consisting of air cooling, e.g. from a temp. region not lower than the Ar3 point, the amounts of solid-solution Nb and solid-solution Ti and the growth of austenite grains at the time of normalizing is inhibited and the precipitation of coarse TiN deteriorating toughness is prevented, by which a structure can be refined. By this method, the thick high tensile strength steel plate free from internal defects, such as inner porosity and microporosity at the time of rolling, and extremely excellent in toughness at low temp. can be produced while obviating the necessity of treatments, such as hardening and tempering.

Filed: 1991-10-16
Abstract: PURPOSE:To maintain good piling-up performance, when a discharging tray is constituted into a deep one which is able to accommodate many sheets of paper, avoiding rolling-up of the paper, which is discharged from an image forming device, into the shape of a barrel. CONSTITUTION:A discharging tray 5 is provided in correspondence to a discharging roller 1, which is installed in a recording paper discharging part of an image forming device, so that the recording paper is piled up one after the other in the discharging tray 5. In the discharging tray 5, an elastic plate 10, which is fixed at the vicinity of the tip part of a bottom plate 6 and which is constituted from a plastic film or an other elastic member, is installed, and the elastic plate 10 is extended to the position at which the tip part of it approaches a roller 1, keeping its position lower than the nipping position of the roller 1. When the recording paper discharged from the roller 1 is placed on the elastic plate 10, a receiving member is gradually lowered because of the weight of the paper sheet. As a result, an angle  - or +  at which the newly discharged form abuts on the form already piled, can be kept at a small value.

Filed: 1985-12-27
Abstract: PURPOSE:To lessen the extent of chromatic aberration in an image due to thermal expansion of a shadow mask, by installing an electron absorbing film, coated and formed by means of metal spraying or frame spraying, in an inner surface of an internal magnetic shield. CONSTITUTION:An electron absorbing film 9 coated to an inner surface of an internal magnetic shield 8 to be opposed to a shadow mask 3 absorbs most of electron beams reflected out of the shadow mask 3. Therefore, a temperature rise in the shadow mask 3 is reduced, whereby deformation due to thermal expansion of the shadow mask 3 becomes lessened. Therefore, chromatic aberration in an image due to slippage of a relative position between a phosphor screen 6 and the shadow mask 3 is relievable.

Title: Phase locked loop circuit
Inventor: KATO TAKEO
IPC: H03L7/14
Filed: 1988-11-24
Abstract: PURPOSE:To output the signal of an arbitrary frequency in the case of a self- traveling oscillation mode by outputting the pulse with pulse width to be specified by a time constant, which is determined according to the values of a resistor and a capacitor, and adding a direct current voltage component, which is obtained through a low-pass filter, to a crystal oscillator when a digital signal is interrupted. CONSTITUTION:A crystal oscillator 300 is connected to a low-pass filter 200 and an output frequency is changed in correspondence to the output voltage of the low-pass filter. A frequency dividing circuit 400 is connected to the crystal oscillator 300 and the output frequency of the crystal oscillator 300 is divided into a prescribed frequency. When an input signal is interrupted, a phase comparator 100 outputs the pulse of the pulse width to be supplied by the time constant which is determined according to the values of a resistor R and a capacitor C. For such a pulse, by adding the direct current component, which is obtained through the low-pass filter 200, to the crystal oscillator 300, the signal of the frequency to correspond to the pulse width can be outputted. Thus, when the input signal is interrupted, the signal of the desired arbitrary frequency can be outputted in the case of the self-traveling oscillation mode.
