Title: Pressure reducing device at starting of engine with manual starter
Inventor: SAKURAI KENICHI
IPC: F01L13/08
Filed: 1981-05-27
Abstract: PURPOSE:To allow even a man of weak power to easily start an engine, by previously setting a pressure reducing device at starting of the engine and automaticallly releasing said pressure reducing device when a crankshaft increases its rotary speed required for starting of the engiene. CONSTITUTION:At starting of an engine, an operating knob 31a is previously rotated to a prescribed direction to rotate a rod 31 to a prescribed amount. Then a semi-circular cam part of the rod 31 is adapted to a rocking end part 21b of a rocker arm 21, and the arm 21 is slightly rocked to move an intake valve 13 downward to a prescribed amount of opening. At this time, a ratchet gear 33 and cam plate 34 are also rotated integrally with the rod 31 to depress one end 37b of a connecting arm 37 downward. In this way, a plunger 32 is depressed, simultaneously a pawl 35 is engaged to a tooth part 33a of the ratchet gear 33 to set a starting pressure reducing device 30 to an operating condition. Under this condition, cranking operation is performed, and the pressure  reducing device 30 can be released by upward motion of the one end 37b of the  arm at perfect explosion of the engine.

Filed: 1989-03-30
Abstract: PURPOSE:To directly detect the position of the position display mark part of an ink sheet by the reflection from the surface of the ink sheet, in the ink sheet for a hard copy apparatus outputting an image, by forming the position display mark part of said sheet into a reflecting gloss surface. CONSTITUTION:A yellow colorant layer 1a, a magenta colorant layer 1b and a cyan colorant layer 1c are formed and a position display mark part 1d having a reflecting gloss surface is also formed by applying aluminum ink. Since the mark part 1d of an ink sheet 1 opposed to a detection sensor 7 has the reflecting gloss surface, the light emitted from the detection sensor 7 is reflected from the surface 1d of the ink sheet 1 to be detected by the detection sensor 7. That is, the reflecting gloss surface 1d is arranged to the head part of the colorant layer part of yellow, magenta and cyan colorants 1a, 1b, 1c. By this method, a recording apparatus can detect the head position of the ink sheet 1.

Title: Fishing rod having out guide
Inventor: MUTO YOSHIOMI
IPC: A01K87/04
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a fishing rod having a fishline guide, capable of being easily removed from a fishing pipe without deformation caused by heat, especially an out-guide. SOLUTION: This fishing rod having an out-guide is a fishing rod in which the out-guide 2 made of a synthetic resin for guiding a fishline is fixed to a fishing pipe with an adhesive R and the out-guide is easily removed by making a difference in softening temperatures between the adhesive R and the out-guide 2 made of the synthetic resin. When the out-guide is adhered and fixed to the fishing pipe by using a thermoplastic resin adhesive having lower softening point than that of the thermoplastic resin out-guide, the out-guide is simply removed by heating it to the softening point of the adhesive, thus, it is very convenient to repair the fishing rod. It is the same when the thermoplastic adhesive is used to an out-guide made of a thermosetting resin.

Title: Laser marker
Inventor: YAMAGUCHI MOTOO
IPC: G06K1/12
Filed: 1987-04-03
Abstract: PURPOSE:To reduce power consumption and enable a smaller laser oscillator to be used, by providing a mask plate on the outside of a transmitting mirror, providing the mask plate with through-holes corresponding to symbols, and providing the mask plate with a reflective surface on the surface thereof opposed to a reflective mirror. CONSTITUTION:The surface of a mask plate 14 comprises a reflective surface 20 and through-holes 19. A total-reflection mirror 6 and the reflective surface 20 constitute a pair of resonators. When glow discharge is developed in a laser oscillator 1, an excitable gas 8 is excited to generate a laser beam 21. When the laser beam 21 passes through the through-hole 19, the beam 18 is projected on a work 23 through a condenser lens 22 to mark a symbol on the work 23. When the laser beam 21 is reflected by the reflective surface 20, the beam 21 is returned into the excited gas atmosphere, is amplified by stimulated emission, and is then again projected on the mask plate 14. Thus, the laser beam 21 is utilized for amplification, so that electrical energy inputted to the laser oscillator 1 can be reduced.

Title: Drainage treatment apparatus for drainage containing phosphate ion
Inventor: MORIIZUMI MASAKI
IPC: C02F1/465
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce the discharge of phosphorus compounds outside a treatment apparatus by installing an adsorption means for removing phosphorus compounds. SOLUTION: An adsorption means for removing phosphorus compounds is installed in a disinfection tank E. An adsorbent 19 comprising active carbon or a porous ceramic material such as alumina and titanium oxide, which can adsorb fine phosphorus compounds, iron oxides, or aluminum oxide, and others, is used. The particle size of the adsorbent is preferably at least 3 mm to prevent clogging. Since the adsorbent 19 is placed in the tank E with reduced suspended solids(SS), clogging caused by the suspended solids can be prevented. Especially by placing the adsorbent upstream from a disinfectant 20 in the tank E, the deterioration of the adsorbent 19 by the disinfectant can be prevented. Since the adsorbent 19 is set in a case 21, when replaced with the new adsorbent 19, the adsorbent 19 can be replaced with the case 21.

Abstract: PROBLEM TO BE SOLVED: To provide a surface acoustic wave(SAW) device capable of being miniaturized by delaying transmission speed and having a high electric/ mechanical connection coefficient (K2) characteristic and a low temperature characteristic by specifying the relation between the pitch of an electrode and the thickness of a piezoelectric substrate. SOLUTION: This SAW device 5 has a glass substrate 1, a piezoelectric substrate 2 and electrodes 3. The piezoelectric substrate 2 is formed on the glass substrate 1 and consists of LN. The electrodes 3 having arrangement corresponding to a device are formed on the piezoelectric substrate 2. When the thickness of the piezoelectric substrate 2 is H, the pitch of the electrodes 3 is λ, and K is 2π/λ, KH is regulated to 0.5-1.0. The glass substrate 1 and the LN substrate 2 are combined and therefore the SAW device itself can be miniaturized. Namely, the glass substrate 1 has a material whose sound velocity is slower than the LN substrate 2 and therefore the glass substrate 1 and the LN substrate 2 are combined. Thus, the LN substrate 2 is affected by the glass substrate and the sound velocity of SAW becomes slow.
