Title: Face light source panel
Inventor: MURASE SHINZO
IPC: G02F1/1335
Filed: 1990-02-27
Abstract: PURPOSE:To prevent incident light from being extinguished by smoothing both end surfaces in the incidence travel direction of light source light positioned crossing an incidence end surface facing a light source into specular surfaces. CONSTITUTION:The face light source panel 9 uses a single acryl-made resin substrate 10 which is made thin and an irregular reflecting surface is formed in the pattern of dots which are distributed with high density. Thus, the face light source panel 9 having the irregular reflecting surface 11 has the upper and lower specularly smoothed surfaces 15 and 16 in the incidence travel direction of the light source light positioned crossing the incidence end surface 14 on one side of the transparent resin substrate 10 facing the light source 19. Therefore, a flat reflecting border surface is formed in the end surface for the light source light which travels in the face light source panel 9 while reflected and refracted. Consequently, the reflecting border surface accelerates, separately from partial light having a large angle, reflection into the face light source panel 9 efficiently to prevent the incident light from being extinguished.

Title: Output check circuit for decode circuit
Inventor: FUKUSHIMA MASAHARU
IPC: H03M7/00
Filed: 1988-02-29
Abstract: PURPOSE:To facilitate the function change and to simplify the circuit constitution by using a ROM receiving an output signal of a decode circuit as address information and outputting the stored data to an output check circuit of the decode circuit. CONSTITUTION:The decode circuit 2 outputs logic '1' to X7 only, '1000000' is inputted to the ROM 5 as address information and a data logic '1' designated by the address information is outputted to a CK. This represents that the output check of the decode circuit is not defective. If logic '1' is outputted to X7, X0 due to a fault of the decode circuit 2, '1000000' is inputted to the ROM 5 as the address information and data logic '0' is outputted to CK from the ROM 5. This shows that the output check of the decode circuit is defective and the output of the decode circuit is inhibited by a gate circuit 4.

Title: Receiver
Inventor: OBAYASHI TOSHIYUKI
IPC: H04N5/44
Filed: 1988-02-29
Abstract: PURPOSE:To improve channel switching by key operation by devising a receiver such that a channel closest to the channel having been received before mode change among memory channels when a full channel sequential selection mode is switched into a memory channel selection mode by the operation of a mode switching key. CONSTITUTION:When the full channel sequential selection mode is switched into the memory channel selection mode by the operation of the mode switching key 2c, whether or not the reception channel before mode change is stored in a memory and preset is judged by a CPU 1. When a channel preset at mode change does not exist, the closest channel among channels stored in the memory of the CPU 1 is sought out. In this case, if the closest channel is only a single channel, the channel is to be set. When plural channels are available, the channel having the highest frequency is to be set. Then the operability of mode change is improved without loss of the reception channel by the operator.

Title: Spike tyre operating with pneumatic pressure
Inventor: AOKI CHIYOMATSU
IPC: B60C11/16
Filed: 1983-03-18
Abstract: PURPOSE:To prevent environmental pollution of dust by constituting a spike tyre as to have the spike pins give no evidence of projection under usual air pressure in the tyre but have them projected by elevating the pressure. CONSTITUTION:Under usual pressure of air in a tyre, the spike pins 3 which are arranged on the middle line of the peripheral face thereof will not be projected from the grounded face because the middle part of the grounded face of the tyre 1 is flat. If the pressure of air in the tyre 1 is elevated from said pressure, the middle part of the grounded face is rounded, thereby projecting the spike pins 3 from the grounded face to function as spikes. Projection and retraction of the pins may be easily adjusted according to the frozen state of road face, hence providing an aid for prevention of environmental pollution of dust.

In consequence, at the same time as big load can be applied,  absorption of up and down fluctuation of a fixer can be easily done.

Title: External signal input device for industrial robot
Inventor: KAWAGUCHI HIROBUMI
IPC: G05B19/18
Filed: 1985-03-08
Abstract: PURPOSE:To realize the wide simplification of the circuit by arranging the output transistor of an optically coupled element in a lattice-shaped manner between the input terminal pulled up by a load resistance and the external terminal with a driver circuit. CONSTITUTION:When an external signal contact 11 is closed, the electric current determined by an input electric current limit resistance 21 flows to the input diode of an optically coupled element 31 and the output transistor is conducted. At such a time, when the output transistor of a driver circuit 51 is conducted by an output terminal 71, a low level appears in correspondence to the external signal contact at the input terminal 61. When an external signal contact 12 is closed, the input terminal goes to be 62. Further, when external signal contacts 13 and 4 are closed, the output transistor of a driver circuit 52 is conducted and the same is executed. Here, when 64 points are inputted by eight input terminals and eight output terminals, the circuit at the later stage than the optically coupled element can be composed of eight load resistances, one IC for the input terminal, an output terminal and one IC to combine the driver circuit, and the circuit can be significantly simplified.

Abstract: PURPOSE:To provide the automatic use of guidance and to provide the visual output service of a telephone number by automatically registering the telephone number guided in number guide service in an abbreviated dial telephone number format. CONSTITUTION:In a digital exchange provided with an automatic abbreviated dial registering means 2 and a telephone number guide means 4, a first judging means 6 judges whether a call of abbreviated dial automatic registration is the one from the telephone set of a general subscriber or a public telephone set. When it is judged that the call is the one from the general subscriber, a second judging means 8 judges the presence/absence of a space in the abbreviated dial registering area 7 of the general subscriber. A registration control means 10 starts up the automatic abbreviated dial registering means 2 replying to the affirmative output of the Judging means 8, and makes the means 2 automatically register the abbreviated dial of the telephone number guided by the telephone number guide means 4 on a blank abbreviated dial registering area.

Filed: 1987-03-02
Abstract: PURPOSE:To effectively suppress convection in the horizontal direction without strengthening magnetic field, by immersing a cylindrical heat convection suppressing column in a raw material melt for single crystal at a concentric position and producing single crystal by pulling method. CONSTITUTION:A crucible 5 is supported on a lower shaft 7 in a pressure container 10 and raw material melt 6 is packed in a crucible 5. A heat 3 to heat the raw material melt 6 is set on the periphery of the crucible 5. When an upper shaft 8 is raised while being rotated, single crystal 1 is pulled up from the raw material melt 6. A magnetic field applying device 4 generates magnetic field advancing from one pole to the other in the horizontal direction in space wherein the raw material melt 6 and the heater 3 exist. A cylindrical heat convection suppressing column 2 is immersed in the raw material melt 6 concentrically with the crucible 5. The raw material melt 6 is halved into inner melt and outer melt by the heat convection suppressing column 2. Since there are slits 11, the heights of the liquid level of the inner and outer melt are equal. When the single crystal 1 is pulled up, the inner melt and the outer melt are reduced while maintaining the same height.
