Title: Apparatus for producing tablet of thermoplastic resin molding material
Inventor: KAJIO MAMORU
IPC: B29B9/08
Filed: 1980-06-14
Abstract: PURPOSE: To precisely control the weight of a tablet, by measuring the loaded amount of material injected into a mold by detecting the air pressure of a piston which applys back pressure to the injected material.  
     CONSTITUTION: The lower end of an injection cylinder 2 having a thermoplastic resin molding material feeding port 1 is tapered to form an injection nozzle 3 whose lower end surface engages slidably with the upper surface of a turn table 5. The turn-table 5 has a plurality of circulary arranged and equally spaced cylindrical molds 4 whose upper and lower ends are open. The piston 6 is inserted into each mold 4 to apply back pressure to the material injected from the nozzle 3, and is connected to an air cylinder arranged below the turn-table 5, and the amount of the tablet 8 injected into the mold is measured by detecting the air pressure within the air cylinder 7. A cylinder 9 is provided which can push down the tablet 8 in the mold 4 every time when the turn-table 5 is rotated stepwise.

Title: Structure of freezer
Inventor: ONO KOJI
IPC: F25D23/06
Filed: 1988-04-01
Abstract: PURPOSE:To save a freezer from reduction in ratio of the effective volume and prevent icing in the vestibule by covering the outer sides of the framework of the main body of the freezer with thermal insulation to form an outer insulation layer and by locating a vestibule thereto on the outer side of the main body. CONSTITUTION:The framework of the main body 1 of a freezer is located on the inner side of thermal insulation 10 and external finishing material 11, that is, on the low temperature side (usually about -30 deg.C) in the freezer, and a vestibule 3 is located on the outer side of the main body, or on the normal temperature side. The insulation separates the vestibule from the main body, any by closing the entrance to the main body by means of a thermal insulation door 4 or the like, the cold from the main body can be withheld from escaping to the vestibule. Moreover, the contact of the vestibule with a normal temperature environment results in a considerable decrease in the amount of dew condensation at the surface of the walls and also in elimination of the occurrence of icing therein. Expansion joints 13 are interposed between slabs 8 laid on the floor between the main body and the vestibule so as to stop the transmission of heat and prevent formation of heat bridges wherein the floor slabs act as a medium.

IPC: B24B37/30
Filed: 1994-04-19
Abstract: PURPOSE:To check any damage to a work holding member in absorbing and easing the extent of impact force at a time when this impact force due to work has acted on the inner circumferential surface of a recess hole by holding the work holding member rockably on the other surface plate. CONSTITUTION:In a state that a work W is pressed to a polishing surface 3 of a lower surface plate 1, this lower surface plate 1 is rotated at a constant speed as feeding this polishing surface 3 with slurry inclusive of an abrasive. Then, an upper surface plate 2 is rocked on the lower surface plate 1 as freely rotation in response to a rotation of this lower surface plate 1, and thereby an underside of the work W is made uniformly in contact with the polishing surface 3 and uniformly polished. At this time, the work W collides with an angular part of a recess hole 7 by dint of torque to be received out of the polishing surface 3 of the lower surface plate 1 in time of polishing, but since a work holding member 6 is somewhat rockable to the upper surface plate 2, this member 6 is rocked to some extent in time of receiving the impact force and thus it absorbes and ease this impact force.

Title: Hermetic package for semiconductor device
Inventor: YAMAMICHI NOBUYUKI
IPC: H01L23/50
Filed: 1982-05-14
Abstract: PURPOSE:To enable to reduce the capacity between leads greatly and utilize glass sealed packages in a wider range by a method wherein the intermediate parts of lead frames are bent up and down partially alternately so that the lead frames are not faced directly to each other. CONSTITUTION:Sealing glass 12 is adhered on a ceramic base 11, the lead frames 13 are fixed thereon, and a part of the adjacent leads is bent up and down alternately so that the side surfaces of the leads are not faced directly. The lead frames do not have all the leads on the same plane, but are bent up and down alternately for example at a part so that the adjacent leads do not oppose the side surfaces thereof. In this manner, since parts without opposition of leads to each other are obtained, the capacity between the leads reduces by that amount.

Title: Rotating force switching method of recording and reproducing device
Inventor: SASAYA TAKUJI
IPC: G11B15/44
Filed: 1986-04-10
Abstract: PURPOSE:To surely engage an oscillating gear with a take-up gear or a supply gear by engaging the oscillating gear with the take-up gear or the supply gear by the kick operation of a motor and driving the motor with a normal voltage. CONSTITUTION:When the gear with which the oscillating gear 10 is engaged is switched from a supply gear 1 to the take-up gear 2, a voltage is applied to a motor 3 for time t1 to reverse the motor, and driving is stopped for time t2, and the voltage is applied to the motor 3 again to reverse it. Then, a pulley gear 5 is rotated clockwise to oscillate the oscillating gear 10. Since driving is stopped for the time t2, the oscillating gear 10 approaches the take-up gear 2 in the state, where the rotation angular velocity is reduced to about zero, and is engaged with the take-up gear 2 even if the oscillating gear 10 is rotated during rotation of a shake arm 9. Since the motor 3 is reversed again, the oscillating gear 10 is surely engaged with the take-up gear 2 with the rotation angular velocity reduced to rotate the take-up gear 2 clockwise.

Filed: 1986-04-10
Abstract: PURPOSE:To enable high-quality recording free of nonuniformity of recording or the like, by providing a carriage-driving motor with a rotary encoder for detecting the position and movement of carriage, using a stepping motor as a ribbon-feeding motor, and driving the stepping motor in synchronism with an output signal from the encoder. CONSTITUTION:A ribbon motor controller 21 is connected to a position detector 16C for a carriage 4, and when the carriage 4 comes to be moved at a constant velocity, the controller 21 controls a ribbon motor 11 in synchronism with zero- crossing parts of a detection signal C from a rotary encoder 10. For example, when driving the motor 11 by two-phase excitation, the controller 21 so controls that the motor 11 makes a step for each two zero-crossing parts of the detection signal C. As a result, the carriage 4 and the ribbon motor 11 for taking up an ink ribbon 9 can be synchronously driven during the recording. Accordingly, ununiformed recording can be obviated, and high-quality recording can be performed.
