Title: Manufacture of helical pinion gear
Inventor: SONODA HIROTETSU
IPC: B21K1/30
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To form a helical pinion gear integrating an outside valve member and a helical gear part by cold-forging. SOLUTION: A large diameter cylindrical part 2A for forming the outside valve member in the following process and a perform 4A of the helical gear part engaged with a rack are formed by cold-forging a circular cylindrical type gear blank.

This excess thickness 24A is removed and the tooth-form having the complete shape is formed with the machining process in the following time.  Therefore, in the case of forming the helical pinion gear integrated with the outside valve member with the cold-forging, since the difference of the outer diameters of the outside valve member and the helical gear member is large, the reducing ratio of area exceeds the permissible value but this ratio can be made to small by attaching the excess thickness and the cold-forging can be executed.

Title: Formation of mask for ion injection
Inventor: KAWADA HARUO
IPC: H01L21/265
Filed: 1979-11-20
Abstract: PURPOSE:To obtain the desired injection layer by a method wherein mask dimensions are prescribed taking into consideration of the tilt angle of the mask end surface and the coefficient of lateral expansion corresponding to the depth of ion injection. CONSTITUTION:The tilt angle theta of the mask end surface, to be formed on a semiconductor substrate, differs according to the method of etching and the condition thereof, but it can not be formed at an angle of 90 deg.. The tilt angle will be about 45 deg.  in the case of a chemical etching and about 80 deg. when an ion etching is used. Therefore, the end surface 9 of the mask 6 on the substrate 8 has the angle theta, and  the high resistance layer 7 to be formed at the depth Zm by an H<+> injection 10 is  expanded on the lower part of the mask to the lateral direction of the Wm. Then  the forming method and condition of the mask are fixed in advance, the angle theta is prescribed, the lateral expansion measurements are found from the graph for Wm/Z m-theta and the mask measurements are fixed taking into consideration of the above  measurements. In this way, a highly precise injection layer is formed, the extent of  integration is increased and the desired characteristics can be obtained.

Title: Apparatus and method for preparing rubber chip
Inventor: MORIYAMA MASAO
IPC: B29B9/04
Filed: 1987-06-17
Abstract: PURPOSE:To obtain a large amt. of rubber chips by a small driving force and at a high speed, by cutting a drawn sheet-like rubber by means of a pair of rollers on whose whole outer circumferential face press-cutting blades are set. CONSTITUTION:When a sheet-like rubber 3 is fed to the first rollers 1A and 1B, it is sent out with the circumferential velocity V1 of the first roller. When the apex of the sent-out sheet-like rubber 3' is caught by the press-cutting blades of the second rollers 2A and 2B, and pulled with a velocity V2 higher than the velocity V1, the material is drawn due to the difference in velocity (V2-V1). The press-cutting blades 10 set on the outer circumferential face of the second rollers bite into the material and the rubber 3' is easily cut interdependently on the recovering force of the sheet-like rubber 3. Cut rubber chips return to the original state due to the recovering force of the rubber itself.

Title: High-stability voltage control multivibrator
Inventor: YUUKI SUOMI
IPC: H03K3/282
Filed: 1978-12-08
Abstract: PURPOSE:To increase both the frequency stability and the ratio between the carrier power and the noise at the frequency band higher than VHF by connecting the small-capacity capacitor plus the elastic surface wave element in series to the time constant circuit which decides the relaxation oscillation frequency. CONSTITUTION:Small-capacity capacitor 13 and elastic surface wave element 12 are connected in series between terminals 4 and 5 which decide the relaxation oscillation frequency of the voltage control multivibrator. As a result, the low frequency of element 12 which is caused by the inter-electrode electrostatic capacity is cut off by capacitor 13. And thus no coupling is given between element 12 and the multivibrator, and the basic frequency of element 12 functions to combine element 12 with the multivibrator. Thus the oscillation frequency is drawn into the basic frequency to start the steady oscillation.

Abstract: PURPOSE:To prevent malfunction of a computer, by providing a circuit which stores a volatilization detecting signal showing that the storage contents of a semiconductor external memory are volatilized and then limiting data transfer, etc. on the basis of said storage circuit. CONSTITUTION:It is supposed that the storage contents of the semiconductor external memory 5 are volatilized due to some factor such as the cut-off of a power supply, etc. In such a case, an external memory controller 4 sets a flag to a flip-flop circuit 6A to show the erasion of the storage contents. While the controller 4 checks the contents of the circuit 6 of its own if an access instruction is delivered to the memory 5 from a CPU2. As a result, if the flag is set within the circuit 6, the volatilization of data arised within the memory 5 is informed to the CPU2. At the same time, an access is inhibited thereafter to the memory 5.

Title: Antioxidizing agent of graphite electrode for steel making
Inventor: IKEGAMI SAKAE
IPC: C01B31/04
Filed: 1984-07-23
Abstract: PURPOSE:To provide an antioxidizing agent capable of reducing wear of graphite electrode by oxidation remarkably and improving the life of the electrode to great extent by dissolving H3BO3 in glycerin. CONSTITUTION:An antioxidizing agent for graphite electrode is prepd. by using H3BO3 as antioxidizing agent and glycerin as solvent. H3BO3 is decomposed thermally at about 300 deg.C and transformed to B2O3 which exhibits superior oxidation preventing effect of the surface of the electrode. But, if water is used as solvent, uniform aq. soln. of high concn. necessary for exhibiting sufficient oxidation preventing effect is not obtd. because of its small solubility in water. Sufficiently high concn. of H3BO3 is obtd. by using glycerin having high solubility for H3BO3 as solvent. Since the soln. has superior wettability and penetrating effect to graphite together with moderate viscosity, separation of the soln. from the graphite surface and outflow of the soln. impregnated into the pores on the surface layer of a graphite electrode are retarded even if the electrode is heated. The soln. is easily penetrated into the pores by coating, impregnation, or spraying.

Title: Knock sensor
Inventor: TANAKA KATSUHIKO
IPC: G01H11/08
Filed: 1980-10-29
Abstract: PURPOSE:To prevent the production of a change in an oscillation frequency at a using time, by a method wherein, in a bimorph type piezo-electric vibrator which vibrates in synchronism with a natural frequency generated at a time when an engine knocks, a thickness of a retainer thereof is thicker than that of a vibrating part. CONSTITUTION:In an ignition device when an engine efficiency is improved by setting forward an ignition time of an engine to the limit to which a knocking is generated, a bimorph type piezo-electric vibrator is employed to a sensor for detecting engine knocking. A thickness T2 of a retainer 5b, supporting a vibrating part 5a of the vibrator, is enoughly thicker than a thickness T1 of the vibrating part 5a to form a double vibrator in a cantilever in which one end is fixed and the other end is free. Thus, even if a slippage deformation is caused between the retainer 5b and a support body surface during the use, a c-part, which forms the vibrating point of the vibrating part 5a, is monolithically structured, and this permits the stabilization of a resonance frequency, which results in enabling to prevent the production of a change  in an oscillation frequency.
