Filed: 1982-04-30
Abstract: PURPOSE:To generate axial force for keeping an engaging state when the internal and external gears interlock each other by forming the inner tooth of the internal gear in such a manner that the thickness is tapered in the direction of interlocking the external gear with the internal gear. CONSTITUTION:A valley portion 14 of an inner tooth 13 is formed like a circular arc, and the center 16 of the circular arc makes an angle of alpha with a tooth ridgeline 17 of the inner tooth 13. The thickness T of the inner tooth 13 is tapered from the inner tooth working surface 15 towards the inner tooth inmost recess 18, in the direction of interlocking an external gear 8 with an internal gear. Therefore, the relationship between a thickness t' in the inner tooth working surface 15 and a thickness t is t'>t. Accordingly, a clutch can be prevented from falling off due to jarring reaction caused by tolerance of the internal and external gears 11 and 8 or a spline shaft 1 or by a vibration or a shock during transmission of rotation.

Inventor: TERAUCHI KAZUHIDE
IPC: G01C15/00
Filed: 1995-03-29
Abstract: PURPOSE: To obtain a laser apparatus whose damage owing to a movement is prevented and whose durability is enhanced by a constitution wherein a freely rotatable lock body for support and a switch are fixed to the rear surface of a horizontal frame and a lock mechanism used also for switch operation is provided. CONSTITUTION: A lock mechanism 20, used also for switch operation, which is provided with a switch for turning on a laser projection device 12 and an operating lever 22 and which supports a support lock body whose tip is fork-shaped, so as to be freely rotatable, is installed at the rear surface of a horizontal frame 9. When the lock body for support is operated by the lever 22, the device 12 is turned on and off, and the lock body for support sandwiches and locks a support 10 when the device is turned off. As a result, in a state that the device 12 is turned off, the support 10 is locked always and surely so as not to be moved rashly.  When a laser apparatus is transported, moved and the like, it is possible to eliminate a fault that the device 12 is damaged when it hits on the inner wall of a case or that the projection of a vertical marking line becomes out of order owing to the damage of a pivot part, and the durability of the apparatus can be enhanced.

Title: Doctor blade for gravure printing
Inventor: KAMETAKA ATSUSHI
IPC: B41F9/10
Filed: 1986-03-29
Abstract: PURPOSE:To prevent the formation of burrs in the edge of a doctor blade and to improve the stability of printing by a method wherein a material which is more likely to be worn out or chipped minutely than the material on the surface side is superposed on the back side of the blade. CONSTITUTION:For instance, a brass material 4 is stuck by an adhesive, or copper plating is applied, on (the back side of) a material 3 of steel or stainless steel having a hardness enabling the primary working of a doctor, and thereby the joining portion B' of steel and copper is worn out in the same way as the portion of the fore end C' on the surface side of a doctor blade. This is because a sufficient doctor pressure is applied on the portion B' owing to the presence of the copper portion. The hardness of the copper portion is low, and therefore the contact surface D' of the copper material 4 with a gravure plate 2 is worn with the wear of the contact surface A' of the plate with the steel material 3 while burrs of the steel material 2 are prevented from occurring. The fore end E' of the outside of the copper material 4 is worn out uniformly even in the condition of a low doctor pressure. Accordingly, such printing troubles as comets and streaks, which take place in the course of printing, can be prevented.

Title: Method of transporting used ion exchange resin
Inventor: NATSUI KAZUJI
IPC: G21F9/28
Filed: 1988-03-28
Abstract: PURPOSE:To establish the inexpensive transporting method which does not generate a large amt. of radioactive waste and is capable of making treatment in a short period of time with a simple transport device by adding a dehydrating agent to a used ion exchange resin to put the resin into a dry state, then pneumatically transporting the resin. CONSTITUTION:A vent valve 4 and a drain valve 5 are opened to remove water from the inside of an ion exchange resin column 1 while the ion exchange resin column 1 is held isolated from a treating water system by closing a treating water inlet valve 2 and a treating water outlet valve 3. The dehydrating agent 12 consisting of, for example, magnesium metasilicate aluminate as an essential component is added from a manhole 11 into an ion exchange resin bed 6. After the drying of the ion exchange resin by the dehydrating agent 12 progresses to the extent of allowing the pneumatic transport, a suction port 14 of a vacuum cleaner 13 or an air ejector is guided to the ion exchange resin bed 6 to vacuum-suck the ion exchange resin. The used ion exchange resin sucked in such a manner is collected into a trap 16 existing at the mid-point of a suction piping 15. The trap 16 is used as it is as a waste container or the collected ion exchange resin is put into another waste container and is treated.

Title: Manufacture of semiconductor device
Inventor: HIRANO YOSHIYUKI
IPC: H01L21/3065
Filed: 1982-04-28
Abstract: PURPOSE:To form a steplike electrode hole by a method wherein a resist film is selectively left on a hole partly removing an oxide film adjoining the resist only by HF plasma to etch any residual resist in the longitudinal and lateral directions. CONSTITUTION:An SiO2 film 12 is formed into a hole on n layer 13 on p type Si substrate 11 to be covered with another SiO2 film 14 further forming a rubber base resist mask 15 in the hole. After selectively etching the film 14 by means of activating HF heated in a furnace, HF is removed to etch the mask 15 isotropically by O2 plasma down to the contracted shape 15' of said mask 15. HF is again introduced to etch the film 14 and then HF is discharged to contract the mask 15' isotropically by O2 plasma repeatedly until Si surface comes into direct contact with the mask 15'. Consequently the hole becomes steplike and the reaction is stopped as soon as Si comes into direct contact with the resist. In this constitution, the dimensional difference in the lateral direction of the resist mask before and after etching may be decided by the size of hole at upper and lower edge of the connecting hole regardless of the adherence of the resist forming a steplike hole with excellent reproducibility.

Abstract: PURPOSE:To achieve high effective sealing of a rotary shaft against vacuum, high pressure gas or other liquid by the use of magnetic fluid. CONSTITUTION:The inner circumference of magnets 9-12 joined to one another is faced to a rotary shaft 1 with a small gap. Magnetic fluid 7 is adhered in the annular form to each joining point between the magnets 9-12 on their inner circumference and the inner surface of the magnetic fluid 7 is made to contact with the rotary shaft 1.
