Filed: 1981-10-30
Abstract: PURPOSE:To improve the yield of a material and to reduce the stages of work by forming a cylindrical part projecting from the outer circumfernce of a disk to the shaft by press work, and forming grooves in the cylindrical part. CONSTITUTION:A slag 11 is drawn into a body consisting of a side plate 5 and a cylindrical part which projects from the outer circumference of the side plate to the shaft, and a through-hole 1 is punched on the basis of the outer circumference. At the outer circumference of the cylindrical part 6, such V-shaped grooves 7 that a flat belt engages them are formed by rolling to complete the manufacture of a pulley. Thus, the outer circumference is worked by rolling after the major part of he pulley is made of the slag 11 by press work, the stages of the work are reduced and the waste of the material is eliminated.

Title: Production of sintered zn-mn alloy
Inventor: SASAKI SADAYUKI
IPC: C22C1/04
Filed: 1991-07-16
Abstract: PURPOSE:To produce a Zn-Mn alloy by a sintering method where zinc yield is extremely improved. CONSTITUTION:At the time of sintering a green compact of metallic zinc powder and metallic manganese powder by heating, metallic titanium more active than manganese is allowed to exist and heating is done in a reducing atmosphere. Because titanium is oxidized and oxygen is dissipated even if the atmosphere is contaminated with oxygen, the oxidation of manganese can be prevented and a sintered Zn-Mn alloy can be produced. Further, when the green compact is heated in a state covered with granular metallic titanium, the oxidation of manganese can efficiently be prevented and the separation from a sintered compact after sintering can be facilitated. Moreover, when heating temp. is regulated to 420-600 deg.C, zinc yield practically becomes 100% and the melting and dripping of zinc can be prevented and the sintered alloy having uniform composition can easily be obtained.

Title: Preparation of coloring material coating liquid for pressure-sensitive recording
Inventor: KAWAI AKIRA
IPC: B41M5/132
Filed: 1985-08-09
Abstract: PURPOSE:To prevent a coating liquid from thickening with time, by adding an inorganic polyphosphate before or during wet grinding of an aqueous dispersed liquid containing a color developer consisting of a salicylic acid derivative and a polyvalent metallic compound. CONSTITUTION:Salicylic acid or a derivative thereof having 1-4 substituent groups such as alkyl, cycloalkyl or halogen on the benzene ring of salicylic acid is used as a salicylic acid derivative, and at least one selected from an oxide, hydroxide or carbonate of zinc, magnesium, aluminum, copper of the like is used as a polyvalent metallic compound, to prepare the color developer. When the aqueous dispersed liquid containing the color developer is wet-ground in the presence of an inorganic polyphosphate, efficient grinding can be performed owing to the low viscosity of the liquid, and the particle size of the color developer is reduced. Accordingly it is possible to sufficiently enhance the color-developing capability, reduce the viscosity of the coating liquid prepared, and prevent the coating liquid from thickening with time.

Title: Transfer material for thermal transfer recording
Inventor: KOBASHI TADAO
IPC: B41M5/42
Filed: 1984-08-23
Abstract: PURPOSE:To continuously control the density of transfer recording dots by a method in which in the case of temperature-rise writing control, the bonding and transference of a tacky material in the non-temperature rise writing section of the recording material to a recording medium is interrupted. CONSTITUTION:A porous layer 122b of non-adhesive solid resin material is formed on the surface of a tacky material 122a containing any colorant of dyes and pigments, and thereby the bonding and transference of the tacky material 122a in the non-temperature rise section during the temperature rise writing control period to the recording medium is interrupted to improve the quality of tacky transferred recording pictures by fogging transfer. To prevent the dissolution of the tacky material layer 122a and also of dyes present in the solvent used during the formation of the layer 122b, solvents for the resin material should be properly selected or the use of aqueous emulsions is recommended. The fogging transfer of the material 122a can thus be prevented by the layer 122b, and when a temperature-rise writing is made on the recording material, tacky transfer recording density is analog-tonally controlled to obtain a multi- tonal picture.

Title: Method of feedback control of air-fuel ratio
Inventor: HARADA SUSUMU
IPC: F02D41/14
Filed: 1980-12-12
Abstract: PURPOSE: To enable accurate control of air-fuel ratio, by judging whether the air- fuel ratio is large or small and by effecting addition and subtraction in accordance with a set sampling signal to stabilize the air fuel ratio at a predetermined level.  
     CONSTITUTION: It is judged through an oxygen concentration detector 1 and an air fuel ratio discrimination circuit 2 whether the ratio of air to fuel is larger or smaller than a set level. Addition and subtraction are effected by a reversible ciunter 5 in accordance with a set sampling signal to stabilize the air-fuel ratio at a predetermined level. If the running condition of an engine goes as shown by a point P 1 , it is discriminated through the detector 1 and the circuit 2 that the fuel mixture is too thick. In that case, a discrimination signal indicating that the air-fuel ratio is smaller than the set level is generated. The reversilble counter 5 having stored the state up to the present is subtracted by the number of sampling signals which have entered into the counter 5 until the output discrimination signal of the circuit 2 is inverted. Since operation is repeated until the predetermined air-fuel ratio is reached.

Filed: 1984-08-27
Abstract: PURPOSE:To prevent rotation unevenness, noise generation by a brush, or residual dust while a cleaner stops by permitting a rotary brush for follow-up upward and downward to a record face and rotating it by the rotation of a turntable. CONSTITUTION:When a cleaner case 10 is turned toward the turntable shaft direction, an idler 6 makes contact with the external circumference 13 of the turntable 12 by a sheet spring 18 to be rotated, and the rotary brush 2 is rotated in the direction of A by pulleys 1 and 5 and a belt 29.

Dust 23 adheres to the external circumference of the rotary brush 2, lifted upward, and accommodated in a dust receiver 8. Then, the dust 23 on the record is removed. This assures that the cleaner is not required to be used during a play, and that the rotation unevenness or noise by a brush resistance is not generated. Since the rotary brush permits up-down movement, it rotates corresponding to the rotation of the record face and its pressing force is stabilized, so that the dust is removed completely.

Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To attain a general-purpose shieve, using a conventional urethane shieve by coupling a first shieve and a second shieve through a first coupling rod and a second coupling rod whose length to a latching part are different respectively and coupling a first shieve and a second shieve through a third coupling rod. SOLUTION: A first shieve 1 and a second shieve 2, conventional urethane shieve are coupled through a third coupling rod 5. A first coupling rod 3 and a second coupling rod 4, whose length to a latching part 7 are different respectively, are set so that the shorter one is on an engine area side. As a result, the length of contact for the first shieve with a wire 6 is longer than that of the second shieve with the wire 6, and the length of contact of a shieve (the second shieve) on a drum area side having much effect on wire torsion can be reduced, thus wire torsion can be prevented. Various wires can be applied with this, because no narrow grooves are used, thereby attaining general-purpose shieve.
