Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a game machine in which a player can sufficiently enjoy a process which leads a result indicating a deterministic change or not. SOLUTION: In a game machine, when the displayed result of a special pattern variably displayed on a variable display device is a big hit, a result as to whether or not the big hit is a deterministic change hit is displayed. When a deterministic change deciding pattern command is outputted from a main base to a display control panel side, the display control panel decides (S2201, S2202) whether the big hit is to be a deterministic change hit or an undetermined change hit based on the command to decide a random number C-RND-K on the basis of a decided value in accordance with a decision. A using pattern is selected (S2206) from among a plurality of kinds of deterministic change sampled patterns. Thus, a sub-game indicating whether the big hit is a deterministic change or undetermined change hit is displayed on the variable display device (S2207) on the basis of the pattern.

Title: Image write-in device
Inventor: YOSHIDA YOSHIKI
IPC: B41J11/42
Filed: 1990-06-29
Abstract: PURPOSE:To finish a copying action without leaving a transfer paper in a machine and to execute error processing by switching a pulse even in the case than a laser synchronization detection signal used for copying sequence control is not received. CONSTITUTION:When the LD error 104 of the abnormality of synchronization is detected, a paper supplying roller is reversely rotated and returned so that the next transfer paper does not come in the case that the transfer paper exists in a paper supply part. Then, the input of the synchronizing signal of a printer sequence control part 70 is automatically switched to a signal from a timer IC 105 from a signal from a laser 103 because the LD error is generated. In the case that the synchronization detection signal used for the copying sequence control is not received in such a way, the pulse is switched to a false synchronizing signal pulse and the action of a carrying system is continued until the transfer paper in the machine is ejected. Thus, the copying action is stopped without leaving the transfer paper in the machine.

Title: Sandblasting nozzle
Inventor: TAKAHIRA TAKUYA
IPC: B24C5/04
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To plane smooth a projecting part of the front of a brick and to extend the life of a nozzle by forming the end of the nozzle into an elliptical cross section, and cutting a part of a side wall that is parallel to the long side of this elliptical form. SOLUTION: A nozzle end 2 is crushed to have a vertically elongated elliptical opening, and a part of a side face parallel to the long side of the ellipse into which the nozzle end is crushed is cut away. Therefore, sand blown out collides against an object surface as shown in Figure (c), and the grinding force of the sand grains at the center of the surface is lower than it will be if the nozzle end has a circular or elliptical cross section. Therefore, if the sand is blown repeatedly, the force of collision becomes uniform over the entire surface, achieving smooth grinding. Also, since the end 2 of the nozzle 1 is notched 7, the wear of that part during blowing is reduced, and the life of the nozzle 1 itself can be prolonged. Therefore, the projecting part of the front of a brick can be planed smooth, and the life of the nozzle can be extended.

Title: Color liquid crystal display device
Inventor: KIMURA TADASHI
IPC: G02F1/1335
Filed: 1985-07-31
Abstract: PURPOSE:To form a twisted nematic liquid crystal display device having high contrast, wide angle range and good color reproducibility by specifying the elastic constant ratio of a liquid crystal. CONSTITUTION:A color liquid cystal display system having the high contrast, wide angle range and color reproducibility of high purity can be realized by specifying the product of the refractive index anisotropy DELTAn the liquid crystal and cell thickness (d) to DELTAn.d>1.5mum. The high contrsat ratio, the wide field angle and further the color reproducibility of the high purity are thereby obtd., but the lift (Tpeak) of transmittivity appears near the threshold value voltage of the transmittivity. This phenomenon is the cause for the generation of gradation inversion in the video of a color TV image, etc. for which the gradation display is necessary. The Tpeak is required to be suppressed to <=2% in order to solve such problem. More specifically, the elastic constant ratio K33K11 (K33: bend (bend), K11: splay (tension) of the liquid crystal material is specified to <=1.0 to suppress the Tpeak to <=2%.

IPC: H03G3/10
Filed: 1993-07-09
Abstract: PURPOSE:To provide a variable gain amplifier in which a gain is decided by a current rate I2/I1, and the gain can be changed by changing the rate, and to prevent the gain by the I2/I1 from not being obtained due to the increase of an emitter resistance (re) of transistors Q1 and Q2 at the time of decreasing the I1 in order to increase the gain. CONSTITUTION:The transistors Q1 and Q2 of a differential amplifier are equipped with constant current sources I01, I02, I03, and I04 for stabilization which supply currents only to those transistors, and by-pass resistors R1 and R2 for gain adjustment or transistors Q3 and Q4 for load resistance. Then, the prescribed currents flow to the transistors Q1 and Q2 regardless of the II. Thus, even when the value of the I1 is small, the currents running through the transistors Q1 and Q2 can be held so as to be more than a constant value by currents I, and the emitter resistance (re) can be prevented from being more than a constant value.
