Title: Heat exchanger
Inventor: KOBAYASHI KAZUO
IPC: F28F3/04
Filed: 1979-11-14
Abstract: PURPOSE: To obtain a laminated heat exchanger having a simple constitution and mass-productivity by piling up a plurality of boxes with bottoms which have tapered side-surfaces to form parallel passages, through which the primary and secondary air streams are passed in the opposite directions to allow the different air streams to exchange heat or moisture with each other.  
     CONSTITUTION: Each of boxes with bottoms 19 and 20 is formed into a pyramidal trapezoid so that when the box 19 is fitted with the box 20 the outsides of side surfaces 25 and 26 near bottom surface 23 and 24 contact closely with the insides of the side surfaces near openings 21 and 22 in order to reliably close the passages by the bottom surfaces 23 and 24 and the side surfaces 25 and 26. This prevents the leakage of the primary and secondary air streams. The primary air A and the secondary air B flowing in from air inlets 33 and 34 in the opposite directions are passed through passages 39 and 40 formed between boxes with bottoms 27a and 27b, and discharged from outlets 35 and 36 respectively, while exchanging heat with each other. Thus, a heat exchanger, which has a simple constitution, large strength, improved effectiveness and mass-productivity, can be obtained.

Title: Dot forming method
Inventor: AKANABE YUICHI
IPC: H04N1/40
Filed: 1985-07-03
Abstract: PURPOSE:To obtain a picture whose lattice pattern is not noticeable in a highlighted part and a shadow part of a dot picture by setting the proportion of the plural picture elements in said two parts larger than that in an intermediate gradation part. CONSTITUTION:When a first dot or initial nine in a 16X16 matrix is or are black picture element(s), a cycle of a length (a) occurs horizontally and vertically. When a fourth one or initial twelve becomes or become black one or ones, a cycle of a length of a/2 in the same directions occurs. Other than the proper cycle of dots which has a length of a/2sq. rt. 2 in the direction angled by 45 deg. from the horizontal direction, these cycles cause the lattice pattern to become noticeable. When the initial ten dots are black picture elements, the cycle is in the direction at 45 deg. and of a length of a/2<1/2>, making the pattern less noticeable. The above is the same with white picture elements. By making the proportion of the plural picture elements in the highlighted part and the shadow part the more larger than that of the intermediate gradation part the farther apart the formers are from the latter, a dot picture whose lattice pattern is not noticeable is obtained.

IPC: B41J2/245
Filed: 1985-07-03
Abstract: PURPOSE:To enable miniaturizing and high speed printing, by providing a driving source with a binary structure. CONSTITUTION:A change of direction of a hammer bank 2 is performed by a movable type linear motor 5, and driving of a uniform speed portion (printing region) of the hammer bank 2 is carried out by a rotary motor 10 and a deformed cam 11. Since the movable type linear motor 5 is able to generate electromagnetic force proportionate to an electric current, a large thrust is easily obtainable, and therefore, the motor is the most suitable driving source for a direction change of the hammer bank 2. As the strength required for control of the uniform speed of the hammer bank 2 is pretty smaller than the one required for a direction change, the rotary motor 10 is not required to the large. The switching over between the linear motor 5 and the rotary motor 10 is performed in accordance with a position signal from a position sensor 7.

Title: Device to detect abnormality in gas control valve
Inventor: NAKANE SHINICHI
IPC: F23N5/18
Filed: 1984-07-17
Abstract: PURPOSE:To detect the abnormality in closing funtion of a gas control valve caused by mechanical trouble, by providing a pressure sensor to detect the internal pressure in a burner to a gas burner. CONSTITUTION:A controller 7 receives a signal from a pressure sensor 8 which senses the internal pressure in a burner 5, as well as to outputs driving signals to control valves 2 and 3. The difference in the internal pressure in a burner during a combustion and non-combustion can clearly be discriminated by P21> P22>0 (mm.Hg). At the time of initial checking before combustion is started, gas control valves V2 and V3 are alternately driven within a specified time (t), and whether the internal pressure in a burner in each state is P22 or not is detected. If an output from the pressure sensor is P22 in a term t3-t4 when the valve 2 is opened and the valve 3 is closed, it indicates that the closing function of a valve V3 is damaged. While, if the pressure is P22 within the term t4-t5, it indicates that the closing function of a valve V2 is damaged.

Title: Waveguide type photosensor
Inventor: WADA HIROSHI
IPC: G01J1/02
Filed: 1985-07-08
Abstract: PURPOSE:To eliminate Fresnel reflected light at the joint part between a sensor waveguide and an optical fiber connected thereto and to obtain the distinctive waveform of back scattered light having no noises due to the reflected light by slanting an end surface of the sensor waveguide and an end surface of the optical fiber to surfaces which cross each other at right angles in a propagation direction. CONSTITUTION:One end side of the optical fiber 4 is connected to a directional coupler 3 and the other end is connected to an end part of a plane waveguide sensor 5. The sensor 5 has a light guide 11 formed in a light-transmissive substrate 10 in an area having a larger refractive index than any other part. Further, the side edge 10A of the substrate 10 containing the end surface of the light guide 11 is slanted by an angle theta in a plane parallel to the substrate surface to a surface 13 crossing the axis 12 in the light propagation direction and the end surface 4A of the optical fiber 4 connected to the light guide 11 so that their axes are aligned with each other is also slanted by the same angle theta. Consequently, light which is propagated in the fiber 4 and returned into the fiber by Fresnel reflection on the end surface 4A and light guide end surface 11A strikes the interface of the fiber 4 at angle larger than the critical angle of total reflection and the light is emitted from the fiber 4.
