Title: Undercut treatment structure for injection mold
Inventor: TANAKA FUMIO
IPC: B29C45/44
Filed: 1990-01-30
Abstract: PURPOSE:To prevent generation of trouble of a mold at the time of molding processing by making mold making easy, by a method wherein an ejector pin with a rotary core is arranged by penetrating through a movable mold and the rotary core is turned by a spring in a process releasing an injection-molded product, which is made into constitution where an undercut part is treated. CONSTITUTION:A circular hole surface 81 through which a rotary core 9 is made turnable by fitting the rotary core 9 to the tip part of an ejector pin 8, a rotary space 83 and a fitting part 84 are formed. When ejector pins 3, 4 are ejected, the ejector pin 8 is moved in the direction of an arrow A by interlocking with the ejection of the ejector parts 3, 4, the rotary core 9 also moved under the same movement as that of the ejection of the ejector parts 3, 4. When a corner 93 passes through an inlet 26 of a hole 25 provided into a movable mold 2, the rotary core 9 begins turning on the surfaces 91, 92 coming into contact with round hole surfaces 81, 82 of the ejector pin 8 as axes in the direction of an arrow D by an action of a spring 10, an undercut part 11 of an injection-molded product 1 is disconnected from an undercut forming part of the rotary core 9 under a state where ejection is completed and the same becomes releaseable. Even under this state, the inside of the molded product 1 is supported by the surface of the ejector pin 8 and it does not happen that the molded product 1 moves synchronously with a rotation of the rotary core 9.

IPC: G02B7/28
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To bring an object into good focus regardless of degree of contrast even if number of dots for displaying contrast is fewer. SOLUTION: An integrator 8A determines contrast value for each frame and an integrator 8B determines brightness value for each frame, and a RAM 16 stores the contrast value and the brightness value for plural frames. A CPU 9 checks the change of brightness, when the change of brightness shows possibility of displaying increase/decrease of contrast, judges the increase/decrease trend based on the stored contrast values, and controls a finder 15 so that the finder displays the judged consequence.

Abstract: PROBLEM TO BE SOLVED: To easily confirm a present location and the state of the road of a progressing direction by seeing the map display of a map range wider than a normal display without a time delay and displaying the reduced part of peripheral parts of stored maps with a data processing. SOLUTION: Generally, in a frame memory, map data of peripheral parts of an area to be actually displayed on a display are stored in addition to map data of the area. Then, the area of the map data is divided into the A area of the vicinity of a location cursor position, the B area other the A area and the C area of the side outer than the B area and the map data of the A area are displayed with a scale 1, that is, by an original figure and the map data of the B area are reduced with a prescribed reduction rate to be displayed and the map data of the C area are reduced with a reduction rate larger than that of the B area to be displayed. Such a display control is performed in a display controller by instructions from a CPU corresponding to request inputs of wide area displays of an external input device.

Filed: 1993-02-08
Abstract: PURPOSE: To provide a twisted helical ferroelectric liquid crystal element having high response and high contrast and to provide a ferroelectric liquid crystal compsn. to be used for the same. CONSTITUTION: A ferroelectric liquid crystal layer 15 having specified thickness is held between plural electrode plates 11, 12 at least one of which is transparent or translucent to constitute a twisted helical ferroelectric liquid crystal cell 10. By applying voltage on electrode plates 11, 12 through the layer, the optical anisotropy of the element can be changed. The ferroelectric liquid crystal which constitutes the layer shows a ferroelectric phase, while it shows a chiral nematic phase at a temp. higher than the temp. of the ferroelectric phase. In the ferroelectric phase, the pitch of natural helix of the ferroelectric liquid crystal is shorter enough than the thickness of the ferroelectric liquid crystal layer 15 of the element so that the ferroelectric liquid crystal has a helically oriented vector structure and has no stabilized surface. In the nematic phase, the pitch of natural helix of the ferroelectric liquid crystal is longer enough than the thickness of the ferroelectric liquid crystal layer 15 so that the layer 15 of the element can be easily oriented.

Title: Transmitting/receiving device
Inventor: KANO HIDETO
IPC: H04B1/40
Filed: 1993-01-13
Abstract: PURPOSE:To switch the high speed frequency with low power consumption by synthesizing the output of a PLL frequency synthesizer and the output of a fixed oscillator, changing the frequency of the received signal by the synthetic sum signal, and feeding the received signal back to a variable frequency generator means by a difference signal. CONSTITUTION:The transmission signal produced by a base band signal processing part 12 undergoes the orthogonal modulation for elimination of undesired waves. Then the transmission signal undergoes the up-conversion through a mixer 31 with the 1st local oscillation frequency and then amplified by a power amprifier 19 up to a prescribed power level after the undesired waves are eliminated by a BPF 20. Thus the transmission signal is transmitted. Meanwhile the output frequency of a PLL frequency synthesizer 35 is supplied to the mixer 31 as the 1st local oscillation frequency for transmission and also supplied to a mixer 36. The mixer 36 synthesizes the supplied local oscillation frequency with the output frequency of a fixed oscillator 38, and this sum frequency is extracted by a BPF 14 and supplied to a mixer 5 as the 1st local oscillation frequency for reception. Meanwhile the difference frequency is extracted by an LPF 37 and fed back to the synthesizer 35.

Title: Flow rate control method
Inventor: TORIMOTO KOICHI
IPC: G05D3/12
Filed: 1986-01-30
Abstract: PURPOSE:To eliminate the useless steps of a valve body and to attain a flow rate control method with high accuracy and high reliability, by storing the difference between the target working amount and the real working amount that is produced with backlash of a screw in an advance/retreat switch mode of the valve body and then giving correction with control to said difference. CONSTITUTION:The pulse wave type signal is impressed to a coil 7 from a controller via a lead wire 28 to give the step revolutions to a rotor 12. These step revolutions give the linear advance/retreat movements to a valve body 14 which is screwed by a male screw 13a of a motor shaft 13 and a female screw 26a of a sleeve 26. Thus the flow rate of intake air is controlled. Under such conditions, the useless steps of the body 14 are mainly due to the backlash of the screw part and therefore have virtually no change under the fixed conditions, i.e., the drive conditions and even at the time when the product is new or its durability is deteriorated. Such a test result is noticed and the pulse signals undergone the correcting control are produced with increase equal to the useless steps stored previously in a controller in case the body 14 is changed to a retreat state from an advance state or vice versa. Thus the body 14 is advanced and retreated.

Title: Flexible aramid film
Inventor: FUJIWARA TAKASHI
IPC: C08L77/10
Filed: 1989-02-01
Abstract: PURPOSE:To obtain a heat-resistant film excellent in heat insulation properties, drape and afterprocessability and improved in adhesiveness because of an increased specific surface area by giving a specified initial tensile modulus and a specified tensile modulus to a film comprising a p-orienting aramid. CONSTITUTION:An aramid film comprising a p-orienting aramid and having an initial tensile modulus <=100kg/mm<2> and a tensile modulus >=400kg/mm<2>. A p-orienting aramid which can be particularly desirably used is poly(p- phenyleneterephthalamide) or poly(p-benzaldehyde). This aramid film has a special tensile behaivor because the film which is inherently highly rigid is a flexibilized one. This special property is related with irregularities of about 1-30mm in size formed on the film by flexibilization. The flexibilization is advantageously performed by forming said irregularities on the film by applying a mechanical force and optionally heat during or after its molding.
