Title: Travel adjuster
Inventor: KUSHIBE YUUKI
IPC: F16H25/20
Filed: 1978-02-02
Abstract: PURPOSE: To easily adjust the travel of a rod, by making a stopper of a gear engaged with a screw shaft and relating the stopper to a switch for controlling the rotation of a motor to accurately displace the stopper.  
     CONSTITUTION: The rod 1 reciprocates within a range limited by stoppers 4, 5. To change the travel of the rod 1, the stopper 4 screw-engaged with the non-rotary rod 1 is rotated by a spur gear 6 coupled to the motor 8 so that the stopper 4 is displaced in the direction of the arrow (b). At that time, the rotation of the motor 8 is transmitted to a screw rod 14 through a chain 12, and a holder 16 containing a microswitch 21 is caused to reciprocate. If the position of an adjusting block 18 is adjusted, the motor 8 stops when the microswitch 21 operates. Therefore, the stopper 4 is accurately positioned.

Title: Molding method of mold
Inventor: NAKADA KUNII
IPC: B22C1/16
Filed: 1980-01-31
Abstract: PURPOSE: To prevent mold deformation by moisture absorption and make hot strength sufficient by compounding a water soluble thermosetting resin in a glue, and drying and hardening the same with heat.  
     CONSTITUTION: Molding sand obtd. by compounding and kneading a water soluble glue and a water soluble phenolic resin is quickly packed in a heated metal mold. The surface of the mold is dried and the glue hardened by the heat of the metal mold, and the thermosetting resin causes thermosetting reaction, thereby creating the surface hardened layer having strength. This core is put into a green sand mold matrix and in the thoroughly moisture absorbed state by allowing it to stand, molten cast iron is poured. In this way, a casting of good dimensional accuracy free from deformation and casting defects is obtained. When it is dried and hardened by the heat of the metal mold, even if the thermosetting resin is unreacted, it causes setting reaction by the heat of the molten metal at the pouring, whereby sufficient high temp. strength is obtained.

Title: Suction device of internal-combustion engine
Inventor: SUGIURA YASUYUKI
IPC: F02B31/08
Filed: 1982-01-29
Abstract: PURPOSE:To contrive to improve the combustion quality centering around the range from light load to medium load by a method wherein the swirl produced by means of the primary side suction air is rendered to be strong and at the same time the inflowing speed of the secondary side leak suction air is raised in order to intensify the swirl.

Because each primary suction passage 26 has a relatively larger cross-sectional area S1, which satisfies the following relationship with respect to the cross-sectional area S2 of each secondary suction passage: (n-1)S1>S2, a large amount of primary side suction air is carried so as to produce strong swirl in a combustion chamber 14 in combination with a strong primary side swirling part. Furthermore, when the third cylinder 4-3 is in suction stroke, for example, the primary side suction airs in the primary suction passages 26-1, 26-2 and 26-4 of the remaining first, second and fourth cylinders respectively flow in the secondary suction passage 28-3 of the cylinder 4-3, resulting in producting a secondary side leak phenomenon.
