Title: Focusing detection means, optical head and optical storage
Inventor: TAKEDA TAKASHI
IPC: G11B7/09
Filed: 1995-02-06
Abstract: PURPOSE: To provide an excellent focus error signal by reducing modulation due to a recording groove and influence from a pit at a spot where diffracted light is focused, using the diffracted light and detecting an focus error. CONSTITUTION: The light outgoing from a semiconductor laser 101 is diffracted into luminous flux 109, 110 by a hologram element 102 to be incident on a beam splitter 103 of a light branching means. The light transmitted through the beam splitter 103 are converged on a recording medium 105 as the spots 113, 114 by an objective lens 104. The light reflected on the recording medium 105 are reflected by the beam splitter 103 to be led to an error signal detection part 108, and the light are imparted with astigmatism by a cylindrical lens 106 to become rays of light 111, 112, and they are made incident on an error signal detection sensor 107.  The modulation due to the recording groove and the influence from the pit are reduced remarkably in the spot where the diffracted light is focused, and by using the light and detecting the focus error, the excellent focus error signal with almost no groove traverse noise and disturbance due to the pit is obtained.

Title: Settling sludge expelling device of settling acceleration plate in settling basin
Inventor: YAMAGATA TETSUO
IPC: B01D21/02
Filed: 1981-02-09
Abstract: PURPOSE: To perform removal of sludge and algae stuck on multiple stages of horizontal sludge settling acceleration plates and prevention of their sticking by irradiating ultrasonic waves to said plates.  
     CONSTITUTION: When an oscillator 8 is moved on a settling basin 1 by the combination of a traveling carriage 5 and a carriage 6, and settling acceleration plates 2 are moved uniformly, the oscillator 8 connected to an ultrasonic oscillator 7 moves while irradiating ultrasonic waves in a downward direction from said oscillator above the plates 2. At this time, the sludge and algae stuck on the plates 2 are stripped by the irradiation of ultrasonic waves to the plates 2. Further, the stripped sludge is pushed by the velocity of flow and is removed successively in such a way as to spill down gradually from the down flow ends in the down flow direction of the plates 2. The sludge removed from the plates 2 settles into a hopper 3 in the lower part by gravity, from which it is withdrawn and removed.

Title: Pattern shape of cmos ic
Inventor: KIMURA TOSHIO
IPC: H01L27/08
Filed: 1984-02-03
Abstract: PURPOSE:To enable the increase in latch-up strength, reduction in chip size and in cost, and increase in reliability by a method wherein the wirings of CMOS drains are bent in the boundary regions between P-channel regions and N-channel regions. CONSTITUTION:An N type high concentration impurity diffused layer: 23 is formed as a guard band in the sub-sub section: 22 in an N type WELL: 21 formed on a P type 20OMEGA.cm substrate, thus taking many contacts 25 with power source aluminums: 24. Similarly, on the N-channel MOS transistor side, a P type high concentration impurity diffused layer: 26 is formed as a guard band, thus taking many contacts with the power source aluminum: 24. A current injected from an output terminal passes under the drain aluminum having the weakest sub-sub and is going to flow to the power source of the P-substrate potential; however, since there is no linear route, the absorption rate increases in the N type well, resulting in the increase in latch-up strength. Thus, the increase in integration and reliability and the reduction in cost are enabled.

Title: Dryer of washing
Inventor: TOKAWA HIDEYOSHI
IPC: F26B9/00
Filed: 1994-01-20
Abstract: PURPOSE:To provide a structure of a heat exchanger which decreases efficiently the temperature and humidity of the exhaust air discharged in a room by city water, in a ductless type dryer of washing. CONSTITUTION:The humid high temperature exhaust air discharged from a dryer is conducted to an indirect water cooling heat exchanger 2 and a direct water cooling heat exchanger 4 with an atomizer 3 for the exhaust air conducted to the indirect heat exchanger 2 and thereafter, the exhaust air is discharged to the outside. In this way, the condensation heat is absorbed by the indirect heat exchanger with a high heat capacity, in a high temperature and humidity and also a high heat transfer efficiency stage. Thereafter, since the air is cooled with partial evaporation of water by the atomizing type direct heat exchanger, the heat transfer efficiency of both direct and indirect heat exchangers can be increased and hence, the dehumidification and cooling capacity of exhaust air can be increased with a smaller volume than a system using only a direct heat exchanger or only an indirect heat exchanger.
