Title: Core bit for rotary percussion drill
Inventor: ENDO TETSUYA
IPC: E21B10/02
Filed: 1994-01-11
Abstract: PURPOSE:To reduce the blur of bit blades and smoothly discharge excavated chips and improve the core quality, by forming the bit blade edge to nearly show a heaved shape or an arc shape and making a conical excavating face to actuate the centripetal force. CONSTITUTION:The blade edge 3a of a plurality of blades 3 provided at the front end of a cylindrical bit body 1 are formed to nearly show a heaved shape or an arc shape and arranged to be almost parallel to the radial direction against the axial line of the bit body 1 or arranged along the rotary direction of the bit body 1. When the bit body is rotated, the excavated face becomes conical and a centripetal force is generated in the bit body 1 and hence the blur of blade edge 3a is reduced. Since the excavated face shows a nearly conical shape, the centripetal force in the forward direction of the bit body 1 is decomposed to the component of the right-angled direction against the blade edge 3a and the component of the outside direction of the blade edge 3a and hence, the discharge effect of excavated chips and the excavating effect are increased.

Title: Varying device for irradiating angle of zoom electronic flash
Inventor: GOTOU SHIGEKANE
IPC: G02B7/10
Filed: 1987-01-23
Abstract: PURPOSE:To obtain an angle of irradiation corresponding to the zooming of a photographic lens by arranging plural flash discharge tubes in the irradiation direction of illumination light and controlling the operation of the plural flash discharge tubes corresponding to the zooming of the photographic lens. CONSTITUTION:The flash discharge tubes 10a and 10b are arranged in parallel in the irradiation direction of flash light, which passes through a reflector 7 and a Fresnel plate 8 directly to illuminate a subject. The flash discharge tube 10a projects a short- distance subject and the flash discharge tube 10b projects a long-distance subject. When the photographic lens is put in zooming operation, a variable power lens 14 moves in an optical-axis direction, which is detected by a zoom ratio detection part 15, whose output is sent to a time constant circuit 16. The time constant circuit 16 generates signals for determining the light emission times of the flash discharge tubes 10a and 10b. Namely, when the zoom ratio is in a telephoto range, a signal specifying a short light emission time is sent to the flash discharge tube 10a and a signal specifying a relative long light emission time is sent to the flash discharge tube 10b. Consequently, the subject is irradiated at an angle of irradiation corresponding to the zoom ratio.

Title: Asynchronous system counter
Inventor: MIYATAKE YUKIO
IPC: H03K23/58
Filed: 1987-01-22
Abstract: PURPOSE:To reduce a delay time by incorporating a circuit which transmits pulses to a high rank bit only when carries occur by means of the pulses after inputting the pulses of increase and decrease in the respective bits and annihilates the pulses at the bit when the carries do not occur. CONSTITUTION:The pulse line 1 of the increase and the pulse line 2 of the decrease are inputted in the clock 4 of a JK flip flop through the operation of an OR gate 3 and in the JK flip flop both J input and K input are 1 and inverting is repeated every time pulses come in. The outputs from the JK flip flop Q5 and the Q6 are connected to AND gates 7 and 8, where it is decided whether the next pulse is made to pass through or to be annihilated. And the pulse output 9 of increase and the pulse output 10 of decrease are transmitted from the AND gates 7 and 8 to the high rank bit as outputs. An up-down counter, which sets a circuit like this as one bit, is asynchronous system and since repeating actions are possible in cycles of one level of a T flip flop as a repeating cycle and it is not needed to wait for the completion of the actions of all the bits, high speed actions are possible.

Title: Camera
Inventor: AIKAWA SATOSHI
IPC: G03B17/02
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To surely shield light at a clearance between a pressure plate and a camera main body even in case of using a metallic pressure plate by arranging a light shielding sheet member between the pressure plate and a printed circuit board. SOLUTION: A clearance exists at the joint part between the gate part 1e of a camera main body 1 and the gate part 2b of a pressure plate 2. For blockading the clearance, a light shielding insulating sheet 3 is protruded from the pressure plate 2, the clearance is covered with the protruded part, and light is prevented from entering a film holding space through the clearance. The thickness of the light shielding insulating sheet 3 is about 1/10 of that of the pressure plate 2, and hence the thickness of the camera is almost never thickened although the light shielding insulating sheet 3 is provided. Consequently, a light shielding construction against a film can be completed while realizing miniaturization of the camera. Thus, a perfect light shielding construction can be provided, in a simple constitution, scarcely requiring the cost and the space for it.

Title: Stabilizing plate
Inventor: MIHASHI DAISUKE
IPC: G11B17/34
Filed: 1989-01-25
Abstract: PURPOSE:To reduce the deformation of a magnetic sheet and to secure a satisfactory head touch by defining a counter surface set to a magnetic sheet as a flat surface which is parallel to a free rotary surface of the magnetic sheet and forming an opening approximately at the center of the counter surface so as to inhibit the relative shift of a magnetic head together with plural recessed parts formed around the opening. CONSTITUTION:The negative pressure is produced at the recessed parts 26-29 of a counter surface 22 in response to the high speed revolutions of a magnetic sheet 15. Thus the sheet 15 is attracted along the surface 22 owing to the negative pressure and rubs a magnetic head 23. Then the sheet 15 is set along the surface 22 since this surface is set parallel to a free rotary surface N of the sheet 15. Furthermore the sizes of parts 26-29 can be changed with each other in accordance with the negative pressure value necessary for each position of parts 26-29. Thus it is possible to reduce the deformation of the sheet 15 and to secure a satisfactory a head touch.
