Filed: 1995-03-17
Abstract: PURPOSE: To form an inner wall of a caulking section into a spherical face having the same shape as that of a ball so as to form a complete valve mechanism consisting of the ball by holding the ball which is mounted in a hole at a holder tip in a fixed state and caulking the edge of the holder tip so as to press it to the ball. CONSTITUTION: In manufacturing a pen tip, a holder 2 through which an ink passing hole 2a is made is chucked with the tip part upward. After an ink channel 2c is worked subsequently to a ball house 2b, a ball 3 is mounted in a tip hole. A caulker jig T having a proper caulking angle θ is pressed to the tip edge of the holder and caulking is performed so as to provide a desired clearance Q between the ball 3 and an inner wall 2e of a caulking section. A ball support rod R1 is inserted from a back end hole and pushed up such that the ball 3 comes into contact with the inner wall 2e of the caulking section. At the same time, the caulker jig T is pressed to a caulking section 2d so as to form the inner wall 2e of the caulking section into a spherical face having the same shape as that of the ball 3.

Title: Swing body
Inventor: SAMEJIMA SHUNEI
IPC: A63B69/00
Filed: 1989-04-05
Abstract: PURPOSE:To inform automatically the set of swings by providing a counter generating the output when receiving an output from a detector responsive to at least a predetermined acceleration to count set values and a pronouncing device for receiving the output from the counter to pronounce an informing sound on sports outfits swung. CONSTITUTION:A desired swing circuit is preset in a down-counter 6 by a preset device 7. By swinging a racket with at least a predetermined acceleration is displaced at least predetermined amount a magnetic body core 3a of a differential transformer so that an output of at least a predetermined level from a converting circuit 4 is generated to generate an output from a clipper circuit 5. This output is counted by a down-counter 6 and the remaining number of swings is indicated by an indicator 10. When the desired number of practice swings are carried out, the content of the down-counter 6 becomes zero so that a circuit 15 for judging zero generates an output to produce an informing sound from an announcing device 16. Thus, when the number of swings reaches a desired one, it is automatically informed, so that the number of swings does not need to be counted and thereby one's mind can be concentrated into the practice swing training.

Title: Reactor of automatic analyzer
Inventor: TSUNASAWA YOSHIO
IPC: G01N35/04
Filed: 1990-03-30
Abstract: PURPOSE:To perform the vibratory stirring of a reaction tube to a rotary type reaction turntable by supporting the rotary shaft of other rotary system on the center-of-rotation part of a turntable having a rotary drive mechanism connected thereto and holding a plurality of reaction tubes in a rotatable manner in a state mounting an eccentric wt. on said rotary shaft. CONSTITUTION:A turntable 2 is rotated at extremely low speed by a motor 22 and an eccentric wt. 30 is rotated at about 50 Hz by a motor 32. Since the wt. 30 is supported on a vibration box 24 in a rotatable manner, a box 24 is not rotated and becomes the vibration source due to the vibration of the wt. 30 and the turntable 2 is fixed to the box 24 and both of them are integrally vibrated. The wt. 30 and the turntable 2 are provided on the almost same horizontal plane and the vertical component of vibration is suppressed. By this constitution, the vibratory stirring of a reaction tube can be performed even with respect to a rotary type reaction tube turntable and, since the rotary shaft 28 of the eccentric wt. 30 and the turntable 2 are supported in a mutually rotatable manner, it is unnecessary to rotate the motor 32 along with the turntable 2 and a structure can be simplified.

Abstract: PURPOSE:To improve the adhesive strength of a thin film to a substrate by carrying out deposition by electrolysis by the use of two colloidal solutions different in particle size at the time of forming a thin film of limited water solubility or a water-insoluble thin film on the surface of a substrate by an electrochemical method. CONSTITUTION:Fine particles of a material of limited water solubility or a water- insoluble material are dissolved in a mecelle aqueous solution of a surfactant having a characteristic of at least charging by means of electrolysis and formed into colloidal state. At this time, a solution A in which the primary particle size of the fine particle material is regulated, e.g. to <=0.05mum and a solution B which consists of a material to be formed essentially into a film and in which the particle size of the material in a colloidal state is regulated to >=0.05mum are prepared. A glass substrate having a thin ITO film is immersed in the solution A and electrified, and electrolytic treatment is carried out to break the micelles of the surfactant enveloping the particles of the film forming material, by which the particles are deposited and a primary layer is formed. Subsequently, the particles of the material to be essentially formed into a film as a secondary layer are deposited by using the solution B and formed into a film, by which a film excellent in the adhesive strength to the substrate as a whole can be formed.

Abstract: PURPOSE:To reduce the effect of a zero-point temperature by forming each gage resistor by a plurality of diffusion layers having different impurity concentration and making the compounding ratios of a plurality of the diffusion layers in the gage resistors corresponding to one or more of sides of a bridge circuit differ with other. CONSTITUTION:A silicon diaphragm has an annular thin projecting strain section 13 surrounded by a central rigid body section 11 and a peripheral thick fixing section 12, and a resistor containing four piezo-resistance effect type gage resistors constructing a bridge is mounted to one side surface of the projecting strain section 13. The gage resistor consists of a first diffusion layer 15 functioning as the principal ingredient of a resistance value and a second diffusion layer 16. Impurity concentration differs in the layers 15, 16. The resistance values of the four gage resistors constituting a bridge circuit are the same, but the ratios of the layers 16 to the layers 15 are differed in the two gage resistors on the outside and the two gage resistors on the inside. When the diaphragm is applied to a pressure detector, the effect of a zero-point temperature can be reduced remarkably.

Title: Waveform shaping circuit for rotation sensor
Inventor: KIMURA TAKASHI
IPC: G01P3/489
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a waveform shaping circuit which can improve the noise resistance of a Hall type rotation sensor to nearly the same degree as that of an electromagnetic pickup type rotation sensor and can be commonly used for both the Hall and electromagnetic pickup type rotation sensors. SOLUTION: A waveform shaping circuit further removes noise by means of a time-base filter 25 after the circuit roughly removes noise by means of an analog primary filter 11 and performs waveform shaping by means of a comparator 13. Therefore, the waveform shaping circuit can have the same noise suppressing ability as a secondary filter has by combining the analog primary filter 11 with the time-base filter 25. Although the characteristics of the above-mentioned combined filter are slightly inferior than those of the secondary filter, the combined filter has less waveform dullness and an excellent noise removing ability. In addition, this waveform shaping circuit can be used commonly for both Hall and electromagnetic pickup type rotation sensors, because both types of sensors can basically use the same circuit.
