Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To prevent the excessive feed of a medium to be printed before the start of printing and to minimize the blank of the medium to be printed at the start time of printing. SOLUTION: Before a printing head 15 starts printing to the recording paper 2 fed in an apparatus main body 1, at first, a pressure contact and separation mechanism 11 moves the printing head 15 to a platen roller 16 by a CPU and, since the racing mechanism of a feed roller part 8 races during the movement of the printing head 15, the recording paper 2 is not fed by the feed roller part 8 and the excessive feed of the recording paper 2 can be prevented and, when the racing by the racing mechanism is completed after the pressure contact of the printing head 15 with the platen roller 16 through the recording paper 2, the detection switch of the feed roller part 8 is turned ON and, since the CPU designates the start of printing to the printing head 15 on the basis of this ON signal, the start timing of printing can be matched with that of feed-out and, therefore,  the blank of the recording paper 2 at the start time of recording can be minimized.

Title: Counter device
Inventor: KIMURA MASATOSHI
IPC: H03K23/66
Filed: 1990-06-01
Abstract: PURPOSE:To enable a counter device to perform its counting action while skipping over the count value of an optional range by correcting the count value of a counter by a desired amount when the count value is coincident with a desired level. CONSTITUTION:The flip-flops 1a-1c are provided to store the skip codes showing the skipping start count values together with the ExNOR gates 2a-2c and an AND gate 5 which detect the coincidence or discordance between the outputs (count values) of the counters 70a-70c and the skip codes stored in the flip-flops 1a-1c. Then the gate 5 outputs the signals showing the coincidence between the skip codes and the count values of the counters 70a-70c when all gates 2a-2c show the coincidence. Then an xOR gate 4 skips the counting actions by the prescribed value when the skipping start count value arrives. Thus it is possible to obtain a counter device that can set an optional count skipping range and an optional skipping start count value.

Abstract: PURPOSE: To stabilize flow within impeller, to improve capacity of a fan, and to reduce noises by making the impeller three dimensional blade which matches the air flow, by enlarging a diameter of an inlet port of the impeller and by enlarging outer diameter of a blade on an inlet part side.  
     CONSTITUTION: A blade 13 of a fan is, as shown in the figure, three-dimensioned and a blade on an inlet side part is cut off, and an inlet port diameter D 1s  on a shroud 12 side is set to be larger than an inlet port diameter D 1h  on a hub 11 side. Being thus designed, a difference between a wind velocity V 2  and a wind velocity V 3  becomes small as the wind velocity V 2  at an inlet part of the fan becomes small to flow the air smoothly and to make an aireddy at the blade inlet part small, so that the intensity of air can be increased and noises can be reduced. Furthermore, D 1s /D 1h =1.1W1.3 is desirable. Also, by extending a blade length l 3  on the shroud 12 side and setting a blade outer diameter D 2s  larger than a hub outer diameter D 2h  to reduce breaking away at the blade surface, capacity of the fan can be improved and noises can be reduced.

Abstract: PROBLEM TO BE SOLVED: To reduce separation of a surface layer from a base layer and reduce a manufacturing cost by forming a paving material into a double layer structure with the surface layer having master stones as aggregates and the base layer having general crushed stones as aggregates and setting the master stones and the crushed stones to preset size ranges and preset continuous porosity ranges as well. SOLUTION: A water-permeable paving material 10 is formed into a double layer structure with a surface layer (a) and a base layer (b). Master stones with a size range of 2.5-5 mm are used as aggregates for the surface layer (a) and general crushed stones with a size range of 2.5-5 mm are used as aggregates for the base layer (b). Both the surface layer (a) and the base layer (b) are molded with a continuous porosity of 10-20%. The surface layer (a) has a thickness in a range of 15-25% of a total thickness, keeps itself at a preset strength and eliminate the waste of the master stones to be used. In this way, a boundary between the surface layer (a) and the base layer (b) is hardly formed and separation from the boundary is reduced, resulting in the economical water-permeable paving material 10 in good appearance.
