Title: Rotary electric razor
Inventor: YAMASHITA YASUO
IPC: B26B19/16
Filed: 1990-02-20
Abstract: PURPOSE:To smoothly and quietly rotate a rotary inner edge all the time by incorporating three of the rotary inner edge, a pair of left and right bearing bases, and a beam member, and supporting them so as to be freely floatable in the vertical direction against the main body case. CONSTITUTION:The rotary inner edge of a cylinder type is brought into sliding- contact with the inner surface of an arch-like outer edge 55 installed in a main body case 1 and rotated. A rigid body structure is formed by connecting integrally each bearing base 5, 6 in the lower part of the rotary inner edge 4 by a beam member 13 formed integrally with or being a separated body from a pair of left and right bearing bases 5, 6 for supporting shafts 12 of both ends of the rotary inner edge 4. Three of these rotary inner edge 4, pair of left and right bearing bases 5, 6 and beam member 13 are formed integrally, and supported so as to be freely floatable against the main body case 1. As a result, twisting, etc., in the periphery of the shafts 12 of both ends of the inner edge 4 do not occur and the inner edge can always be rotated smoothly and quietly, and also, an inclination of the inner edge can be prevented and the cutting quality can be improved.

Title: Color sensor
Inventor: TOMITA MASAHARU
IPC: H01L31/103
Filed: 1985-03-01
Abstract: PURPOSE:To obtain a color sensor, which does not react to ultraviolet rays whatever, by a method wherein the photoelectric conversion layer of the color sensor having three photoelectric conversion cells, each having some one of three kinds, of blue, green and red color filters, on its light incidence side is constituted of a P-type a-Si layer converted into a P-type by doping an impurity and an impurity-undoped weak N-type a-Si layer. CONSTITUTION:A lower electrode 3 consisting of ITO and so forth is coated on the bottom surface of a frame body 11 made of glass and so forth, and a P-type a-Si layer 51 converted into a P-type by doping an impurity and an undoped weak N-type (N<-> type) a-Si layer 54 are laminated thereon. The P-type layer 51 is formed according to a DC glow discharge decomposition using gasses, such as hydrogen diluent gas containing SiH4 of 10% in concentration and diluent gas containing B2H6 of 0.1% in concentration and the N<-> type layer 54 is formed according to a DC glow discharge decomposition using one-kind of gas only, such as hydrogen diluent gas containing SiH4 of 10% in concentration. IN such the P-N<-> junction element, the spreading of a depletion layer at the time of impression of inverse bias is small. Therefore, the element almost never has a spectral sensitivity to the ultraviolet and infrared regions and has a spectral sensitivity to the visible region only. Accordingly, this color sensor becomes one that does not react to the ultraviolet region whatever.

An output proportional to the phase difference of the output of the PC 6 is generated, fed to an LPF 7, whose output controls the VCO 8. The reference speed of the transmission PLL circuit comprising the PC 6 - the frequency divider 9 depends on the LPF 7 and the frequency divider 9, but the response is quickened by setting the cut-off frequency of the LPF 7 to a value being >=4 times of the highest frequency of the modulation signal.

Abstract: PURPOSE:To roll a long-sized material fed intermittently in the lateral direction by rotating normally and reversely a pressing roller provided parallel to the direction of feeding of a metallic blank material to an anvil while reciprocating the roller perpendicular to the material. CONSTITUTION:A round metallic rod 3 is fed intermittently from the direction of the arrow 4 between an anvil 1 and a roller 2. At the same time, external force is applied to move the roller 2 horizontally to the right or left as shown by arrows 5, 5a. At this time, a sector gear 7 is fixed to the shaft 6 of the roller 2 and engages with an idler gear 8, and the idler gear 8 engages with a rack 10 fixed to a housing 9. Accordingly, when the roller 2 is moved in the direction of the arrow 5, the roller 2 is rotated in the direction of the arrow 12 through the idler gear 8 and sector gear 7, and rolls the round rod 3. The round rod 3 is fed by specified length when the roller 2 arrives at a position shown by an alternate long and short dash line 2a. When the roller 2 is moved in the direction of the arrow 5a, the roller 2 rotates in the reverse direction and rolls the round rod 3 again. The long-sized round rod is rolled by repeating the above-mentioned process.

Title: Article carrying method
Inventor: MURATA HIROHIKO
IPC: B65G27/32
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To silently carry even any article without collapsing the article by setting vertical directional acceleration positive when the article transfer surface is moved in the transfer direction in the horizontal direction, and setting the acceleration negative when the transfer surface is moved in the inverse direction of the transfer direction. SOLUTION: Positive-negative vertical acceleration α(|α|<g) changing to an advance-retreat is applied to a vibrating plate 1. When the vibrating plate 1 advances, force being [m(g+α)] vertically acts on an article (m). Here, (g) is gravitational acceleration, and (m) represents mass of the article. That is, since [acceleration x mass (m)] of horizontal directional motion becomes smaller than frictional force when large frictional force acts on the article (m), the article (m) moves forward in the horizontal direction together with the vibrating plate 1. When the vibrating plate 1 retreats, force being [m(g-(α)] acts in the vertical direction on the article (m), but frictional force at this time is sufficiently small and horizontal directional excitation force is larger, so that the article (m) relatively advances to the transfer surface 1a.

Abstract: PURPOSE:To prevent a telephone line from being opened during speech by providing a voltage detecting circuit in a base set, detecting it by the voltage detecting circuit that the telephone line voltage of the base set is lowered when a branched telephone set is closed, and stopping the operation of a timer. CONSTITUTION:When it is desired to transfer the contents of the conversation to the owner of a hand set, a telephone set 13 is kept to a holding state and the owner of the hand set is called. When the owner of the hand set picks up the hand set after hearing the call, a transmission circuit 17 is turned to an operating state. Then, the base set operates a telephone line control circuit 1 and branches a telephone line 2 and the speech is realized with a caller instead of the branched telephone set 13. At such a time, when the branched telephone set 13 is set in a speech state or the holding state, the voltage to be applied from the telephone station of the telephone line 2 is lowered. This is detected by a voltage detecting circuit 12 and the operation of a timer 11 is stopped. Therefore, the telephone line 2 is not opened during speech.
