摘要： A drainage pump has a pump body, a vane, a ring, and a circumferential wall. The pump has a cylindrical small vane pump chamber and a large vane pump chamber extending from and communicating with the small vane pump chamber. A suction inlet communicates with the small vane pump chamber and a discharge outlet communicates with the large vane pump chamber. A chamber slope portion is formed between the small vane pump chamber and the large vane pump chamber. The vane is adapted to be driven by a motor and is rotatably mounted to the pump body. The vane includes a large vane portion received in the large vane pump chamber and a small vane portion extending from the large vane and received in the small vane pump chamber. The small vane portion and the large vane portion rotate together when driven by the motor. A vane slope portion is formed between the large vane portion and the small vane portion. The ring has a central opening, positioned between the large vane portion and the small vane portion. The small vane portion extends through the central opening. The circumferential wall surrounds the periphery of the large vane portion and extends upwardly from the ring. The ring covers the lower end of the large vane portion. The circumferential wall collides against any drainage water returning from the discharge outlet into the pump body to absorb shock and prevent the drainage water from returning directly to the pump body from the discharge outlet.

摘要： An image display apparatus comprise: a light source section; a light modulator that modulates light delivered from the light source section to display an image; a light level control section that adjusts the amount of light delivered from the light source section to the light modulator; and a display control section that updates the image displayed on the light modulator during a first period and a second period alternately switched therebetween. The display control section updated in the first period to a first image and a black image in this order and updates in the second period to a second image and the black image in this order. The light level control section sets the amount of light delivered from the light source section to be greater than that in other periods during a predetermined switching period including a point to switch between the first period and the second period.

摘要： It is possible to achieve the protection of software with reduced overhead. For example, a memory for storing an encrypted code prepared in advance and a decryptor module for decrypting the code are provided. The decryptor module includes, for example, a three-stage pipeline and a selector for selecting one output from the outputs of each stage of the pipeline. When a branch instruction is issued and subsequent inputs of the pipeline are in the order of CD′1, CD′2, . . . , the decryptor module outputs a first decrypted code by performing a one-stage pipeline process to CD′1. Next, the decryptor module outputs a second decrypted code by performing a two-stage pipeline process to CD′2, and the decryptor module outputs a third decrypted code by performing a three-stage pipeline process to CD′3 (and subsequent codes). Therefore, in particular, the overhead to CD′1 can be reduced.

摘要： An optical apparatus includes an optical element disposed on an optical path along which the light flux emitted from a light source travels, and a polarizing element disposed on the light flux emitting-side of the optical element. The polarizing element includes a first prism having a light flux incident-side end surface on which the light flux having emitted from the optical element is incident and an emitting-side inclined surface inclined to the light flux incident-side end surface, and a polarizing element body provided on the emitting-side inclined surface, the polarizing element body transmitting first linearly polarized light out of the light flux having passed through the first prism and reflecting second linearly polarized light polarized perpendicular to the first linearly polarized light toward the first prism. The optical element is integrated with the polarizing element with an interposed adhesive layer formed on the light flux incident-side end surface. The refractive index n0 of the adhesive layer is set to satisfy the following equation: 1≦n1/n0×sin [2φ−arcsin {n0/n1×sin(θ−φ)}−2φ] where n1 represents the refractive index of the first prism, θ represents the angle between the optical axis of the light flux emitted from the light source and the light flux incident on the light flux incident-side end surface, φ represents the angle between a plane orthogonal to the optical axis and the light flux incident-side end surface, and φ represents the angle between the orthogonal plane and the emitting-side inclined surface.
