Title: Die for die casting
Inventor: SEGAWA KAZUYOSHI
IPC: B22D17/22
Filed: 1981-12-22
Abstract: PURPOSE:To improve productivity and product quality by providing a projecting part  to a stationary die so as to contact with the materials cast in runner parts and parting the product part and the runners and drawing the runners from the intermediate  mold simultaneously by die opening force in the stage of opening dies. CONSTITUTION:A molten alloy to be cast is charged into an injection chamber 78,  main and auxiliary runners 80, 82, a gate 84 and a cavity 72, and is cooled to solidify  and to shrink. Therefore, the alloy in the runner 80 part adheres tightly to the projecting part 86 of a stationary die 60 by enclosing the outside circumference thereof and  is hardly detachable from the die 60. The cavity 72 is so formed that a product 96  clings to a moving die 64 as in an ordinary way. In the starting stage of die opening  upon completion of cooling of the molten metal, the alloys in the runners 80, 82 are  kept stuck tightly to the mold 60, and the alloys in the gate 84 and the cavity 72  move left together with the die 64 and an intermediate die 66. Thus the alloy in the  gate 84 is parted by die opening force. When the die 64 moves left further, the die 66  is stopped; therefore the product 96 detaches from the die 66 and moves left while  sticking on the die 64. Upon completion of die opening the product is ejected from  the die 64, and the runners 80, 82 are ejected together with the alloy in the chamber 79 from the die 60.

Abstract: PROBLEM TO BE SOLVED: To enable the engine oil of a cylinder head to drop on an oil pan even in a driving area where an amount of generation of blow-by gas becomes increases. SOLUTION: A lubricating oil return passage 20, piercing through from the lower end of a cylinder block 3 up to the top of a cylinder head 4, is formed on the lower side than a cylinder axis CL of an engine 1.

Title: Bar code reader
Inventor: TSUJI NOBUHIKO
IPC: G06K7/10
Filed: 1988-08-19
Abstract: PURPOSE:To attain an immediate reaction by issuing an alarm signal from a signal inputted to a decoding part when bar code information is decided to be unreadable, and selectively outputting data supplied to a corrected data input means. CONSTITUTION:In a normal condition, a bar code 2 is detected by a detecting part 7, and whether or not it is in a prescribed format is decided by a decoding part 8 based on a detecting signal. When the decision result is normal it is outputted through an output selecting part 11 and an output terminal 12 to a host computer after converting into the encoded data. On the other hand, when the bar code 2 is dirty or scratched, and the detecting signal from the detecting part 7 is decided to be undecodable by use of the decoding part 8, a command 13 is issued to an alarm 9 and an output selecting part 11. Thus, the alarm 9 issues an alarm signal, and an output selecting part 11 selectively outputs the data supplied to a corrected data input/output means 10 by a manual operation. Thus, the immediate reaction is attained when automatic reading impossibility is generated.

Filed: 1982-11-26
Abstract: PURPOSE:To reduce electric impedance and to attain ease of matching with a power supply by laminating at least >=2 polymer piezoelectric film stretched uniaxially and making parallel the electrode split direction and the stretched direction of the piezoelectric film. CONSTITUTION:Silver is vapor-deposited on both sides of a PVF2 (polyvinylidenefluoride) stretched uniaxially, the deposited film is polarized at a high temperature under an electric field, and the film is quenched rapidly to form a PVF2 piezoelectric film. Then, a narrow paper-tablet electrode 2 is formed by etching so as to be parallel to the uniaxial direction of the piezoelectric film. The opposite side 3 of the electrode 2 is patternized for a whole surface or partly as required. The PVF2 piezoelectric film 1 is folded and laminated. This is adhered onto a printed board 5 so that the narrow paper-tablet electrode 2 and a copper plate in common use of the sound reflecting plate and the electrode are overlapped with each other. Leads are led out from common electrode leads 3 to a common electrode section 6 of the printed board 5 by using silver-epoxyd- tight paint 7.

Title: Image reader
Inventor: OTA AKIRA
IPC: H04N1/028
Filed: 1993-08-20
Abstract: PURPOSE:To obtain the maximum light quantity and to effectively use the original light quantity of a light source by shifting the optical axis position of the light source on an original surface in a direction separated far from the optical axis position of a convergence lens. CONSTITUTION:An original 1 whose position is decided by a glass plate 2 is illuminated with the light source 3 from the obliquely lower side. Reflected light(part of irregular reflecting light) from the original 1 is converged by a rod lens array 4, and is image-formed as an unmagnified erected image at a conjugate length position on the side opposite to that of the original 1. Image- formed light information is located at the conjugate length position. The information is photoelectrically converted by a photoelectric conversion element 5 packaged on a substrate board 6, and is taken out to the outside. At this time, since a light source optical axis 101 is designed so as to be located at a position far from the light source 3 than a rod lens optical axis 102, almost the maximum light quantity can be obtained on the rod lens optical axis 102.

Title: Image forming device
Inventor: TANADA SHINICHI
IPC: G03G15/16
Filed: 1984-10-02
Abstract: PURPOSE:To decrease the scattering of a developer for a long period of time by constituting integrally a conductive member, cleaning means and electrostatic charger before transfer. CONSTITUTION:The negative bias voltage of the same polarity as the polarity of a toner T1 is kept impressed to a conductive roller 101 by an electric power source 102. The toner T1 of the negative polarity among the toners scattered or suspended in the laminar flow of a photosensitive drum shown by a broken line is subjected to the electrostatic force by which said toner is pushed back to the photosensitive drum side by the effect of the electric field formed between the photosensitive drum and the conductive roller by the impression of such bias voltage. The toner is thus attracted to the place of the photosensitive drum where a positive latent image is formed. On the other hand, the toner T2 of the positive polarity having the polarity opposite from the polarity of the toner T1 receives the electrostatic force toward the conductive roller side by the effect of the electric field and is attracted to the surface of the conductive roller. The toner T1 of the negative polarity is thus attracted to the image part on the photosensitive drum 1 and the toner T2 of the positive polarity onto the roller 101 and therefore the scattering of the toner from the roller 101 to the lower stream side is substantially eliminated.

Title: Semiconductor light emitting element
Inventor: SAKAI KAZUO
IPC: H01S5/042
Filed: 1989-08-11
Abstract: PURPOSE:To enable an active layer to confine enough injected carriers and to be improved in light emitting efficiency as satisfying a lattice matching condition with respect to a substrate by a method wherein a first barrier layer, which is thinner and smaller than the active layer in electron affinity, is arranged at the interface of a heterojunction between the active layer and a clad layer. CONSTITUTION:A first barrier layer 5 formed of semiconductor, whose electron affinity Ea is smaller than that of an active layer 4 and is smaller than the layer 4 in thickness, is provided to an interface of the heterojunction between the active layer 4 and a clad layer 6. Therefore, lattice constants of a substrate 1, clad layers 2 and 6, the active layer 4, and the first barrier layer 5 are roughly matched with each other, and as the first barrier layer 5 is thin, the probability that holes subsist in it becomes small. Therefore, electrons injected into the active layers 4 can be restrained from overflowing to the P-side clad layer 6, so that electrons can be confined into the active layer 4. By this setup, a device high in efficiency and operable in the wavelength region of blue light can be obtained.
